Summary of the Invention

Problems to be Solved by the Invention

[0004] The technology disclosed in Patent Document 1 has a large number of setting items, and the screen is appropriately switched to find the desired setting item and change the setting content. Such processing is complicated and there is a problem that smooth setting cannot be performed.

[0005] The object of the invention of the present application is not limited to this, and the applicant also has the intention to obtain rights through divisional applications, amendments, etc. for a configuration aimed at obtaining the effects exerted by the components of the configuration disclosed in this specification, drawings, etc. For example, in this specification, the problem of reading the part described as "can be" as "is a problem" is disclosed in this specification. The problems are described as independent ones, and the applicant also has the intention to obtain rights through divisional applications, amendments, etc. alone for the configuration for solving this problem. Even if the problem is implicitly grasped from the description of the specification, the applicant has the intention to make a part of the configuration described in this specification the scope of claims by amendment or divisional application. Also, problems combining these independent problems are disclosed.

Means for Solving the Problem

[0006] (1) A system having a notification function for a user and a setting function for setting matters related to the notification by the notification function, which displays an immediate first menu screen when there is an operation on the screen normally displayed, and displays a second menu screen for the above-mentioned setting without immediacy when a predetermined item on the first menu screen is selected, and the first menu screen is provided with items that can be set immediately and items for going to the second menu screen.

[0007] By operating the screen normally displayed, an immediate first menu screen is displayed, so that the user can immediately select the item to be executed at that time. When a predetermined item is selected from the first menu screen, a second menu screen is displayed, so that the user can set matters related to the desired notification while operating the second menu screen.

[0008] The system is preferably, for example, mountable in a vehicle. When it is mountable in a vehicle, it is preferable that the notification provides information beneficial for driving and running. The system may be composed of a plurality of devices and equipment, but it is preferable that it is composed of one device. The screen normally displayed is, for example, a screen displayed during operation.

[0009] (2) It is advisable that when the first menu screen is displayed for a certain period of time, it returns to the original screen, and when the second menu screen is displayed for a certain period of time, it does not return to the original screen. By looking at the first menu screen, the user can immediately determine whether there are any immediate items to be processed at present. If there are no items, it can be left as it is and it will automatically return to the standby screen. When looking at the second menu screen, the user may consider how to set the items while viewing the display content of the display unit, and there may be no operation for a certain period of time. If it returns to the original screen in such a case, it is necessary to perform an operation to transition to the screen for processing again, which becomes cumbersome. Therefore, by not allowing automatic return, the user can consider carefully and perform operations reliably.

[0010] (3) For the first menu screen with immediacy, it is advisable to display all selectable items on one screen, and for the second menu screen for non - immediate settings, it is advisable to limit the number of items displayed on one screen to a reference value or less.

[0011] On the first menu screen with immediacy, the items selectable on that first menu screen are listed. So, the user can immediately select the target item and perform the desired process. Since the number of displays on one screen of the second menu screen is limited, the items for settings displayed on that second menu screen are easy to see, it is easy to find the target item to be set, and the target item can be selected reliably. By limiting the number of displays, the number of screens of the second menu screen increases, but since it has no immediacy, it can be searched slowly. Especially when the selection of items for settings is made in a touch - type manner for the display screen, since the number of displays is limited, for example, the area of one setting item can be enlarged or the distance from adjacent setting items can be increased, and it is possible to prevent accidentally touching different items or pressing multiple adjacent setting items simultaneously, which improves the operability.

[0012] (4) For the second menu screen for non-immediate settings, it is preferable to arrange a predetermined number of setting items vertically and provide a function to display the title of the setting item and the current setting content in the display area of the setting item. Selectable setting items are displayed on the second menu screen, and the current setting content of the setting item can be known together with the title of the setting item. The user does not need to enter the hierarchy for setting the setting value of the setting item one by one to confirm the current setting content, so the operability is improved, which is preferable.

[0013] (5) For the second menu screen for non-immediate settings, it is preferable to arrange a predetermined number of setting items vertically and provide a function to display the title of the setting item and the current setting content in the display area of the setting item, a function to display a setting menu screen for changing the setting content of the setting item when there is an operation on the display area, and a function to switch the current setting content without displaying the setting menu screen when an operation is performed on the area for displaying the current setting content on the second menu screen. By doing so, it is possible to set the setting content of the setting item without transitioning to the lower-level setting menu screen. The function to switch the current setting content without displaying the setting menu screen is applicable when the number of candidates for the setting content is small. When the number of candidates is large, it is preferable that such a switching function does not work. The small number is preferably 2 to 3, and more preferably 2.

[0014] (6) For the second menu screen for non-immediate settings, it has a menu screen including a display area for setting items that displays the title of the setting item and the current setting content, and a setting menu screen for changing the setting content of the setting item, which is separate from the menu screen. The display statement of the setting content to be displayed on the menu screen and the display statement of the setting content to be displayed as selection candidates on the setting menu screen are held as separate data, and each display statement having the same content preferably has a simpler expression on the menu screen.

[0015] On the menu screen, the current setting content can be displayed within the display area of the setting items, and the user can understand the content even if only vaguely. When transitioning to the actual setting menu screen, the setting content as the selection candidates is correctly displayed, so the user can correctly understand the content. For a simple expression, for example, it may be a mark or symbol, but it is better to use a term with a small number of characters, and when reducing the number of characters, it is better to use an abbreviated form.

[0016] (7) It is preferable to have a function of performing processing for the setting of the setting item when a first operation is performed on the setting item displayed on the second menu screen, and a function of displaying an explanation screen of the setting item when there is a second operation different from the first operation.

[0017] By performing the first operation, the user can change the content of the setting item or perform other settings, and by performing the second operation, the user can display the explanation screen to know the content of the setting item. For example, while operating, the user can smoothly and timely know the content of the setting item without referring to the instruction manual, can immediately judge whether it is a necessary item for the user, and can efficiently set appropriate notification content for the user.

[0018] The first operation is preferably a short press, for example, and the second operation is preferably a long press, for example. The function of performing processing for the setting is, for example, to display a setting menu screen for changing the setting of the selected setting item, or to change the setting content of the setting item while remaining on the menu screen. The explanation screen is preferably an explanation pop-up screen, for example.

[0019] (8) It is preferable to have a function of performing processing for the setting of the setting item when a first operation is performed on the setting item displayed on the second menu screen, and a function of displaying an explanation screen of the setting item when there is a second operation different from the first operation, and not to display the explanation screen even if there is the second operation on the normal display screen and the first menu screen.

[0020] The screen displayed during normal times is the one that is always shown, so an explanatory screen is not necessary. For example, if the user accidentally performs a second operation different from the first operation, it would be cumbersome to display an explanatory screen, but it is acceptable not to display it as this eliminates such cumbersome issues. The first menu screen is for selecting processes with immediacy, so the content of each process is easy to understand and an explanatory screen is not needed. For example, if the user accidentally performs a second operation different from the first operation, it would be cumbersome to display an explanatory screen, so it is acceptable not to display it as this eliminates such cumbersome issues. In particular, for example, if the first operation is a short press on the screen and the second operation is a long press on the screen, the first menu screen is for performing processes with immediacy. For example, since the user may keep pressing the screen in a hurry, it would be cumbersome and inhibit the immediacy of the process if an explanatory screen is displayed due to that long press, so it is advisable to set it not to display.

[0021] (9) The notification function preferably has a first warning by a moving CG and a second warning using an image corresponding to the scenery including the warning target, and is provided with a function of displaying the second warning after displaying the first warning at a predetermined timing.

[0022] After attracting the user's attention with a moving CG, an image corresponding to the scenery including the warning target by the second warning is displayed, so it is good because it makes it easier for the user to recognize the warning content. The second warning performed after the first warning is preferably to issue warnings continuously. By issuing warnings continuously, the continuity between the CG of the first warning and the image of the second warning becomes stronger, and it is good because it can effectively attract attention and enable recognition of the warning content through the reproduction of continuous images. The area for displaying the CG of the first warning and the area for displaying the image of the second warning are preferably at the same position. By displaying the first warning and the second warning at the same position, the integration and continuity of the two become stronger, so it is good. The CG for the first warning is preferably related to the type of warning. The image of the second warning is preferably an image seen from the driver's seat, and more preferably a real image. The warning target is preferably a specific device or equipment, and in the case where such equipment is not present, it may be a specific location, but it is good because it is easier to understand if it is a specific device or equipment.

[0023] (10) The notification function has a first warning by moving CG and a second warning using an image corresponding to a scene including the warning target, and has a function of displaying the second warning after displaying the first warning at a predetermined timing. The first warning may be one that repeatedly plays the movement a plurality of times.

[0024] If the image of the second warning is continuously shown after the first warning, it is difficult to draw attention. However, by showing the moving CG of the first warning for a certain period of time and repeating a series of movements a plurality of times, it becomes easier to draw attention. Since the movement is played back a plurality of times, the first warning by CG may also be noticed. For example, when the CG is related to the type of warning target, the type of warning target can be recognized by the first warning, and then, by displaying an image corresponding to the scene including the warning target, the actual situation can be understood, which is preferable.

[0025] (11) The notification function has a first warning by moving CG and a second warning using an image corresponding to a scene including the warning target, and has a function of displaying the second warning after displaying the first warning at a predetermined timing. After displaying the first warning, the process of displaying the second warning may be repeatedly performed a plurality of times.

[0026] For example, when the second warning is continuously displayed after the first warning, the display time of the second warning becomes long and the attention level for the first warning displayed first decreases. However, by displaying the first warning consisting of moving CG after the first warning, the first warning may also be noticed. In particular, when the image indicated by the second warning is a still image, if a non-moving image is continuously displayed, it is difficult to draw attention. However, by appropriately displaying the first warning consisting of moving CG, movement can be generated in the peripheral vision of the user, and it can be recognized that there is a target to be cautious about, which is good.

[0027] The display time of the first warning may be, for example, several seconds. With such a duration, movement can be recognized. Also, when the user looks at the screen upon such recognition, after waiting at most several seconds, an image of the second warning such as a live-action image will be displayed. Thus, the user can confirm the content of the second warning without staring at the screen for a long time.

[0028] Moreover, if the first warning is a CG corresponding to the type of warning target, by notifying the CG corresponding to the type after displaying an image of the actual scenery, attention will also be drawn to the CG, and the understanding of the type of warning target displayed in the second warning will be enhanced. In particular, when approaching, for example, when continuously displaying a warning screen even when no sound is ringing, by appropriately inserting a moving CG, movement can be created in the user's peripheral vision, enabling the user to recognize that there is a warning target that requires attention. Along with this, when looking at the screen, after waiting at most several seconds, it is acceptable to be able to view the image of the second warning.

[0029] The multiple repetitions are not necessarily limited to integers. For example, it may end with the first warning like 2.5 times, or it may stop during the first or second warning, but it is better to use integers.

[0030] (12) The notification function has a first warning by a moving CG and a second warning using an image corresponding to the scenery including the warning target, and is equipped with a function of displaying the second warning after displaying the first warning at a predetermined timing. The CG has a movement of zooming in on the warning target, and it is advisable to display the image by the second warning after the zoomed-in video. The first warning can enable the user to recognize what the warning target is, and then, by giving the second warning, it can be used to notify the existence of the recognized warning target.

[0031] (13) The notification function includes a function of displaying a law enforcement information screen, and it is preferable that the types of law enforcement information to be notified on the law enforcement information screen are notified in a predetermined color. Since the law enforcement information is displayed on the law enforcement information screen and the types of law enforcement information are notified in color, the user can easily understand at a glance what kind of law enforcement information is being notified by looking at the color. The law enforcement information includes, for example, public law enforcement information and information regarding speed enforcement guidelines, etc., and their types are distinguished by color. For example, it is difficult to find if the types of such law enforcement information are displayed in text, but it is good that it can be understood at a glance by distinguishing with color. The predetermined color may be displayed at a predetermined position within the law enforcement information screen as in the embodiment, for example. Also, the predetermined color may be displayed on the LED light emitting part in the embodiment, for example, but if it is displayed within the law enforcement information screen, it is good that the relationship with the displayed law enforcement information can be easily understood.

[0032] (14) The notification function preferably includes a function of displaying a predetermined screen after displaying the law enforcement information screen for a predetermined time, and a function of displaying the law enforcement information screen when a predetermined location on the predetermined screen is operated. Even if the law enforcement information screen disappears and the content is missed, it can be redisplayed with a simple operation and the content can be confirmed. The predetermined screen is preferably the original screen before the law enforcement information screen is displayed, and for example, it is good to be a waiting screen for map display.

[0033] (15) The notification function includes a function of displaying a predetermined screen after displaying the law enforcement information screen for a predetermined time, and a function of displaying the law enforcement information screen when a predetermined location on the predetermined screen is operated. When there is no law enforcement information on the road during driving, it is preferable that the law enforcement information screen is not displayed even if the predetermined location is operated. When the road during driving has nothing to do with law enforcement information, the law enforcement information screen is not displayed, so it is good that it is possible to easily know whether there is law enforcement information by operating the predetermined location.

[0034] (16) For the same type of warning target, the warning target that requires attention for passing is defined as a specific warning target, and it is preferable that the notification function relaxes the conditions for the specific warning target to become a notification target. Even for the same type of warning target, for the specific warning target, the conditions for becoming a notification target are relaxed, so it becomes easier to be notified, and it is notified from a relatively far position away from the warning target. Therefore, it can be understood that it is necessary to proceed with caution or detour from a distant position, and safe and smooth driving can be achieved. The same type of warning target may include, for example, those with the same part in the name, such as "level crossing" and "level crossing requiring attention". Relaxing the conditions for becoming a notification target may include, for example, increasing the target separation distance or widening the angle included in the notification target. The notification of the specific warning target should preferably be in a more prominent warning mode than the notification of the normal warning target.

[0035] (17) The notification function preferably overlays and displays a message window for displaying information related to the warning target on the map screen, and the overlay position should be a place where it is difficult for the vehicle to proceed. Since the message window is displayed overlaid on the map screen when displaying, for example, the same map screen can be used regardless of whether the message window is displayed or not. It is preferable that the standby screen such as the map screen can be displayed full screen. The map information that cannot be seen due to overlapping in the message window is set as a place where it is difficult for the vehicle to proceed, so there are few adverse effects. It is good to fix the display position of the message window. The place where it is difficult to proceed should preferably be the right end of the screen. The message window should not be always displayed but should be displayed when necessary. For example, when two windows are displayed with the vehicle at the current position in between, each window should not overlap and should display information about the same warning target.

[0036] (18) The program according to the present invention is preferably a program for causing a computer to realize the functions in the system according to any one of (1) to (17).

[0037] The inventions (1) to (17) described above can be arbitrarily combined. For example, at least a part of the configuration of at least one of the inventions (2) and later may be added to all or a part of the configuration of the invention shown in (1). In particular, it is preferable that the invention shown in (1) is an invention to which at least a part of the configuration of at least one of the inventions (2) and later is added. The applicant of the present application also has the intention of obtaining patent rights, design rights, etc. by means of amendment, divisional application, change application to design registration application, etc. for those including these configurations.

Effect of the Invention

[0038] According to the present invention, settings can be easily and appropriately made. In addition, it becomes easier for the user to recognize the warning content, and an appropriate warning can be given.

Embodiments for Carrying Out the Invention

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain the technical features that can be adopted by the present invention. The configuration, shape, etc. of the described devices are merely illustrative examples, and the present invention is not to be construed as being limited thereto. Without departing from the scope of the present invention, various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art.

[0042] [Basic Configuration of the System] FIG. 1 and FIG. 2 show the configuration of a radar detector, which is a form of an in-vehicle device suitable as a system constituting the system of the present invention. The radar detector 1 includes a thin rectangular case 2, and is attached and fixed, for example, on a dashboard of a vehicle using a bracket 3 attached to the lower part on the back side of the case 2.

[0043] On the front surface of the case 2, a display unit 4 is provided. The display unit 4 is composed of a color liquid crystal display. For example, a 3.5-inch color liquid crystal display is used. The display unit 4 is provided with a touch panel 5 for detecting which part of the display unit 4 has been touched. Also, on the left side of the front surface of the case 2, an LED light emitting unit 6 and an illuminance sensor 7 are arranged. The LED light emitting unit 6 has a bar-shaped light emitting region extending in the vertical direction and functions to emit various colors. For example, it may be composed of full-color LEDs or the like. The LED light emitting unit 6 emits light in various colors for warning, etc., according to, for example, the type and urgency of the warning or notifications such as public inspection information. The illuminance sensor 7 is arranged above the LED light emitting unit 6 and detects the ambient brightness. Based on the detection result of the ambient brightness output from the illuminance sensor 7, the control unit 18 adjusts the brightness of the display unit 4.

[0044] On the right side surface of the case 2, a card insertion slot 9 for mounting a memory card 11 as a removable recording medium is provided, and a card reader 10 is built inside the card insertion slot 9 in the case 2. By inserting the memory card 11 through this card insertion slot 9, the memory card 11 is mounted on the card reader 10. The card reader 10 takes in the data stored in the mounted memory card 11. The data stored in the memory card 11 includes, for example, update information such as information on new warning targets (position information such as latitude and longitude, type information, etc.). The update information is stored and downloaded, for example, via the control unit 18 to a database 19 built into the device, and the data is updated.

[0045] The database 19 can be realized by a non-volatile memory (for example, a NAND Flash memory) built into the microcomputer of the control unit 18 or externally attached to the microcomputer. Also, the memory card 11 itself may be configured as part or all of the database 19. Note that map data and information regarding certain warning targets are registered in the database 19 at the time of shipment, and data, etc., regarding additional warning targets are updated as described above.

[0046] Place the GPS receiver 13 inside the upper part on the back side of Case 2, and further place the microwave receiver 14 and the wireless receiver 15 beside it. The GPS receiver 13 receives radio waves transmitted from artificial satellites in the satellite orbits, measures the latitude and longitude of the current position, and outputs the obtained current position information. In addition to the positioning function based on the radio waves from the artificial satellites, the GPS receiver 13 has a function of receiving signals from the quasi-zenith satellite "Michibiki" for more accurate positioning, a function of using Russian satellites such as GLONASS (Global Navigation Satellite System) to calculate the current position on the ground, a function of receiving signals from the "Himawari" of the multi-purpose transport satellite to correct the error of the current position measured by receiving the radio waves of the artificial satellite shell in the satellite orbit and improving the positioning accuracy, a function corresponding to the Indian geostationary satellite-based satellite navigation augmentation system such as GAGAN (GPS Aided GEO Augmented Navigation), and a function corresponding to the global navigation satellite system of the EU (European Union) such as GALILEO (Global Navigation Satellite System). The microwave receiver 14 receives microwaves of a predetermined frequency emitted from the speed measuring device. The wireless receiver 15 receives wireless radio waves in the VHF and UHF bands for traffic control communication, etc. A speaker 16 is built in at a predetermined position inside Case 2.

[0047] Below the lower part on the back side of Case 2, a DC jack 12 is arranged. This DC jack 12 is used to supply power to the radar detector 1. For example, a connector 22 of a cigarette plug cord can be connected to the DC jack 12, and the cigarette plug cord can be connected to the cigarette socket of the vehicle to receive power supply. Instead of the cigarette plug cord, it is advisable to use an OBDII adapter 21 that can be connected to the OBDII connector of the vehicle. The OBDII connector is also called a fault diagnosis connector, is connected to the ECU of the vehicle, and various vehicle information is output regularly. Therefore, by connecting this OBDII adapter 21 and the OBDII connector on the vehicle body side, and connecting a connector 23 attached to the tip of the connection cord of the OBDII adapter 21 to the DC jack 12, while supplying power to the radar detector 1, the control unit 18 can regularly acquire various vehicle information.

[0048] This vehicle information includes the vehicle's driving distance, vehicle speed, injection time, intake air volume, remaining fuel information, etc. The remaining fuel is the amount of fuel remaining in the current fuel tank and is output with a resolution of 0.5 liters. Therefore, by regularly acquiring the remaining fuel and recording the timing when a change occurs between the previous remaining fuel and the current remaining fuel, it can be said that the fuel consumed from the previous change to the current change is 0.5 liters. Also, some output information related to fuel consumption (such as lifetime fuel consumption, current fuel consumption, instantaneous fuel consumption, etc.) regularly. The control unit 18 can display the acquired vehicle information on the waiting screen, or acquire speed information even in places where satellite information cannot be received, such as inside a tunnel, and issue more accurate warnings.

[0049] In Case 2, an acceleration sensor 25, a gyro sensor 26, and an air pressure sensor 27 are provided. The acceleration sensor 25 detects the acceleration related to the vehicle and obtains the acceleration in two directions, the front-rear direction and the lateral direction of the vehicle. The gyro sensor 26 integrates the angular velocity so that the control unit 18 can obtain the traveling direction of the own vehicle on the map. The air pressure sensor 27 is used to measure the altitude change due to the change in air pressure.

[0050] The control unit 18 is a microcomputer equipped with a CPU, ROM, RAM, non-volatile memory, I / O, etc., and is connected to each of the above-described units as shown in FIG. 2. The control unit 18 creates information to be notified to the driver based on information input from the various input devices (touch panel 5, GPS receiver 13, microwave receiver 14, wireless receiver 15, acceleration sensor 25, gyro sensor 26, barometric pressure sensor 27, etc.), and outputs the information using the output devices (display unit 4, LED light emitting unit 6, speaker 16, etc.).

[0051] The functions of the radar detector 1 in the present embodiment are realized by the CPU included in the control unit 18 executing the firmware stored in the NAND Flash memory of the control unit 18. The firmware stored in the NAND Flash memory can be updated by the new firmware stored in the memory card 11.

[0052] "Basic functions of notification and warning using the display unit 4, etc." The main information output from the output device of the radar detector 1 is warning information for prompting the driver's safety. The warning information is output, for example, in the following cases. The control unit 18 obtains the distance between the position (latitude and longitude) of the warning target stored as map information in the database 19 and the current position (latitude and longitude) of the vehicle detected by the GPS receiver 13, and when the obtained distance is equal to or less than a predetermined distance, the control unit 18 outputs warning information from the output device (GPS warning function). Also, for example, when the control unit 18 detects a signal corresponding to the microwave in the frequency band emitted from the speed measuring device by the microwave receiver 14, the control unit 18 outputs warning information from the output device (radar wave warning function). Also, for example, when the control unit 18 receives a predetermined radio wave by the wireless receiver 15, the control unit 18 outputs warning information from the output device (wireless warning function). The radar detector 1 causes the driver to recognize a dangerous location where a traffic accident is likely to occur by outputting the warning information. Thereby, the radar detector 1 can prompt the driver to drive safely. Note that the above-described warning information is an example, and actually, various other warning information is output to the driver. The warning information includes, for example, visual information composed of a predetermined image, video, character, etc. output to the display unit 4, and those using sound or voice output to the speaker 16. Specific warning contents will be described later.

[0053] *Standby screen display The control unit 18 outputs warning information for prompting the driver for safety when a predetermined event occurs. On the other hand, when such an event does not occur, the control unit 18 displays a predetermined standby screen as shown in FIG. 3 for example (standby screen display function). This standby screen display function displays various pieces of information useful for driving. For example, it displays information based on GPS such as the speed, latitude, longitude, altitude, etc. of the own vehicle detected by the GPS receiver 13 in numerical values, graphs, animations or other forms, or displays the presence of GPS satellites detected by the GPS receiver 13 in numerical values, animations or other forms, or displays in numerical values, graphs, animations or other forms based on predetermined OBD information and vehicle information acquired by the OBDII adapter 21. Further, the standby screen display function also has a MAP display function that accesses the database 19 based on the current position detected by the GPS receiver 13, reads out the map data stored therein, and displays it.

[0054] FIG. 3(a) shows an example of the display screen output to the display unit 4 by the MAP display function. The control unit 18 reads out and displays the surrounding map information from the database 19 in the main display area R1 of the entire display screen of the display unit 4 based on the current position of the own vehicle. At the position of the own vehicle on the map, an arrow-shaped own vehicle icon 31 is displayed. The display position of this own vehicle icon 31 is set as a predetermined position determined in the main display area R1, and based on the display position of the own vehicle icon 31, the map information is displayed, for example, with the heading fixed (always displayed with the traveling direction upward). The display position of this own vehicle icon 31 is, for example, near the center on the lower side within the main display area R1.

[0055] The control unit 18 has a function of overlapping and displaying the first window W1 at the upper left corner within the main display area R1, and a function of overlapping and displaying the second window W2 at the upper right corner within the main display area R1. The first window W1 takes a layout in which, for example, a traveling speed display section is arranged on its upper side and a clock display section is arranged on its lower side. The traveling speed display section displays the current vehicle speed of the own vehicle. The control unit 18 outputs the own vehicle speed obtained, for example, by calculating the speed from the displacement / history of the current position and the elapsed time based on the received GPS radio wave, or by acquiring the vehicle speed information from the vehicle via the OBDII adapter 21, to the traveling speed display section. The clock display section displays the current time. The control unit 18 acquires the current time from, for example, an internal clock or GPS information and outputs it to the clock display section. The second window W2 displays the place name and road name of the current position.

[0056] Figure 3(b) shows an example of an acceleration waiting screen, and takes a layout in which a large acceleration meter 32a is arranged on the left half side of the main display area R1, two small meters 32b and 32c are arranged vertically on the left half side, and a character meter 32d is arranged on the lower right side. The control unit 18 displays a schematic diagram of the own vehicle and a diagram / animation that shows the state of acceleration around it within the acceleration meter 32a so that the direction / strength of the acceleration applied to the vehicle detected by the acceleration sensor 25 can be understood. Also, in the illustrated initial values, an analog clock is displayed on the upper small meter 32b, a compass is displayed on the lower small meter 32c, and the own vehicle speed is displayed on the character meter 32d. It is preferable that the information displayed on the small meters 32b and 32c can be changed by setting.

[0057] Figure 3(c) shows an example of an inclination waiting screen, and in order from the left side of the main display area R1, a longitudinal inclination display section 33a that shows the longitudinal inclination of the vehicle, a compass display section 33b, and a lateral inclination display section 33c that shows the lateral inclination of the vehicle are arranged. The control unit 18 obtains the longitudinal and lateral inclination angles of the vehicle based on the output of the acceleration sensor 25, and represents the state of the inclination angles by the orientation / posture of the schematic diagram of the own vehicle in the longitudinal inclination display section 33a and the lateral inclination display section 33c. In the illustrated example, since the inclination angle is 0, both the own vehicle and the display are horizontal.

[0058] FIG. 3(d) shows a standby screen for a hybrid vehicle, which is an example of a standby screen based on OBD information and vehicle information obtained via an OBDII adapter. This standby screen has a layout in which two mini meters 34a and 34b are arranged above the main display area R1, and hybrid information is displayed in the area below them. In this example, the control unit 18 displays the engine speed on the left mini meter 34a and the engine water temperature on the right mini meter 34b. The hybrid information includes the engine speed 34c, the engine water temperature 34d, the HV air conditioner power consumption 34e, the engine operating state (green: engine brake, red: engine drive) 34f, the current engine running ratio / instantaneous fuel consumption 34g, the generator power generation state 34h, the front motor operating state (green: regeneration, yellow: drive) 34i, the battery remaining amount 34j, the linear motor state (green: regeneration, yellow: drive) 34k, etc., which are displayed at appropriate positions.

[0059] * Alarm output based on event occurrence The control unit 18 executes processes to implement functions such as a GPS alarm function, a radar wave alarm function, and a wireless alarm function according to the generated event. Each alarm function switches and warns the display on the display unit 4 from various standby screens to a map screen that displays a map around the vehicle position when an event occurs. The standby screens include a screen that displays the map shown in FIG. 3(a) and screens that display information other than the map as shown in FIGS. 3(b) to (d). The alarm screen for visually performing the alarm, for example, as shown in FIG. 4, etc., has a layout in which a map screen showing a map around the vehicle position displayed in the main display area R1 of the entire screen of the display unit 4 and a message window are overlapped and displayed at a predetermined position on the map screen. The message window includes an alarm image display window W3 arranged at the lower left end and a message window W4 arranged at the lower right end in this embodiment. The details of the alarm function by the message window will be described later.

[0060] When the microwave receiver 14 detects a signal corresponding to the microwave in the frequency band emitted from a speed measuring device (such as a mobile radar, hereinafter simply referred to as "radar"), the radar wave warning function switches the display on the display unit 4 from the standby screen to the warning screen and displays it (see Fig. 4(a)), and it is a warning function that outputs a warning sound from the speaker 16.

[0061] For example, when the microwave receiver 14 detects the microwave in the frequency band of the microwave emitted by the radar, the control unit 18 reads out the schematic diagram, CG or photo of the radar stored in the database 19, displays it in the warning image display window W3, and displays the information related to the warning in the message window W4. The control unit 18 displays the warning screen and reads out the voice data stored in the database 19 to output a voice "There is a radar. Pay attention to speed" from the speaker 16.

[0062] When the wireless receiver 15 receives the radio wave emitted by an emergency vehicle or the like, the wireless warning function is a function that issues a warning so as not to interfere with its running or the like. In the wireless warning function, frequencies such as traffic control radio, car stereo radio, digital radio, very small radio, police activity radio, police telephone, police activity radio, vehicle location radio, helicopter radio, fire helicopter radio, fire radio, emergency radio, highway radio, security radio, etc. are scanned. When a radio is received at the scanned frequency, the display unit 4 is displayed with a warning screen in which a schematic diagram or CG indicating that the radio corresponding to the frequency stored in the database 19 for each radio type has been received is displayed in the warning image display window W3, and at the same time, the voice data stored in the database 19 for each radio type is read out, and a warning voice indicating the type of the radio is output from the speaker 16. For example, when traffic control radio is received, a voice such as "There is traffic control radio. Pay attention to speed" is output.

[0063] The GPS warning function is a process that is executed at predetermined time intervals (for example, at intervals of 200 ms) by an event from a timer in the control unit 18, for example, during the execution of the standby screen display function. It uses the current position detected by the GPS receiver 13 and the warning target information stored in the database 19 to determine whether the warning conditions (for example, a predetermined proximity relationship) are satisfied, and issues a warning when they are satisfied.

[0064] First, an example of the type of warning target is as follows: drowsy driving accident location, vehicle speed measurement device (radar type / H system / loop coil / LH system), mobile vehicle speed measurement area, speed limit switching point, enforcement area, checkpoint area, no-parking monitoring area, N system, traffic monitoring system, intersection monitoring point, signal violation suppression system, police station, accident-prone area, on-vehicle target-prone area, sharp / continuous curve (highway), branch / merge point (highway), ETC lane advance notice (highway), service area (highway), parking area (highway), highway oasis (highway), smart interchange (highway), gas station inside PA / SA (highway), tunnel (highway), highway radio reception area (highway), prefectural border notification, road station, viewpoint parking, zone 30 area, level crossing, etc. There are various types. For such various types, it is better not to display a warning screen for all of them as warning targets, but to issue a warning for the targets desired by the user selected through settings.

[0065] The warning target information stored in the database 19 is information related to individual warning targets, including position information including longitude and latitude for specifying the position of the warning target, and warning target specifying information useful for the driver to identify the warning target. In this embodiment, the position information is absolute position information using longitude and latitude. This is preferable because the relative position relationship with the current position detected by the GPS receiver 13 can be easily obtained.

[0066] The information for specifying the warning target includes type information indicating the type of the warning target, character information indicating the position of the warning target, voice information indicating the warning target, image information indicating the warning target, and the like. In the case where the voice information, image information, etc. indicating the warning target correspond to the type information of the warning target, they are not stored as warning target information for individual warning targets, but can be stored as separate common information in a predetermined storage area. And when issuing a warning, the control unit 18 can read out the type information stored as warning target information, acquire the corresponding image information, voice information, etc. from the type target, and output a warning.

[0067] As common image information, there is image data such as a schematic diagram that makes it easy to understand the type of the warning target. The schematic diagram is also a mark for enabling the type of the warning target to be intuitively understood from the visual sense. For example, there are those created as images in 3D or the like for a vehicle speed device, a police car, a police officer, etc. These schematic diagrams can be drawn and output on the display unit 4 when notifying, so that the driver can intuitively understand the type and content of the warning target currently being notified. Then, the own vehicle icon 31 is drawn at the position of the own vehicle on the display area of the display unit 4, and the target icon 35 composed of the schematic diagram is drawn at the position of the warning target location (see Fig. 4(b) etc.). It is more preferable to display the own vehicle icon 31 and the target icon 35, as it allows for an intuitive understanding of the position of what warning target is present.

[0068] Also, the voice information is data for outputting, from the speaker 16 as voice information, relative positional relationships such as "1 km ahead in the left direction, highway H system" and "immediately ahead, general road N system", and the type of the warning target, etc. In the above examples, the voice data indicating the relative positional relationship between the current position of the vehicle and the warning target, such as "left direction", "1 km ahead", "immediately ahead", etc., and the voice data for specifying the type and content of the warning target, such as "general road N system" and "highway H system", are managed and stored separately, and when notifying, the control unit 18 combines and outputs the respective voice data.

[0069] By separately managing fixed voice information (voice data), etc. according to the types of these warning targets, it is not necessary to register information of the same content as warning target information for each warning target, and the consumption amount of the memory area can be reduced.

[0070] Then, for example, the control unit 18 periodically accesses the database 19 based on the current position. When the distance between the loop coil that is the warning target and the own vehicle becomes any one of 2 km, 1 km, and 500 m, which is the approach warning distance stored in the database 19, the control unit 18 reads out the data of the schematic diagram / CG or photo of the loop coil that is the warning target from the database 19, displays it on the warning image display window W3, and displays the information regarding the warning on the message window W4. The control unit 18 reads out the voice data stored in the database 19 and outputs a warning sound from the speaker 16 for approach notification. For example, when approaching 500 m, the voice data "There is a loop coil 500 m ahead, pay attention to speed" is read out from the database 19 and output from the speaker 16.

[0071] Furthermore, the database 19 stores map data including road network information. This road network information is data necessary for searching for a recommended route in car navigation, etc., and includes information such as a road network (road layout) and traffic regulations such as one-way traffic. Furthermore, this road network information stores the position information (latitude and longitude) of the nodes at intersections or inflection points of roads as nodes, and information indicating which other nodes each node is connected to. Based on the information indicating the connection relationship of each node in this way, adjacent nodes are connected to each other, and the connected nodes become a road link. Note that since it does not guide to a destination like a car navigation device, there is no detailed data such as display data of facilities and houses, and it is simple data.

[0072] [Setting function] As described above, the radar detector 1 of the present embodiment has a notification function for the user, such as an alarm function that issues an alarm or the like in accordance with the occurrence of an event. Further, the radar detector 1 has a setting function for setting matters related to the notification. Matters related to this notification include, for example, those related to the entire system such as the screen brightness and base color, whether to issue an alarm for a large number of alarm targets, the way of the alarm, individual notification conditions and functions such as the sound effect, and the setting of optional products connected to the radar detector 1 such as an OBDII adapter. In the present embodiment, in order to perform the setting by the setting function easily and smoothly, it has the following various functions.

[0073] (The first menu screen with immediacy and the second menu screen without immediacy) When there is a predetermined operation on the standby screen normally displayed by the control unit 18, the control unit 18 has a function of displaying a first menu screen with immediacy, and when a predetermined item on the first menu screen is selected, it displays a second menu screen without immediacy. The predetermined operation is, for example, a touch on the standby screen. As shown in FIG. 5(a), the control unit 18 displays a predetermined standby screen in the main display area R1 of the entire display screen of the display unit 4. When the touch panel 5 detects contact within the main display area R1, the control unit 18 switches the display of the display unit 4 from the standby screen to the first menu screen shown in FIG. 5(b), and displays the first menu screen on the entire display screen of the display unit 4.

[0074] The first menu screen includes a volume-up button 41a and a volume-down button 41b as an example of item buttons that can be set immediately. Further, the first menu screen includes a setting button 41c for transitioning to the second menu screen. Furthermore, the first menu screen includes a standby change button 41d, an item change button 41e, a registration button 41f, and a top button 41g. Each button is arranged appropriately vertically and horizontally.

[0075] The volume increase button 41a and the volume decrease button 41b are buttons for adjusting the volume. As shown in Fig. 6(a), when the control unit 18 detects that each button area has been touched by the touch panel, it changes the volume setting to a level increased or decreased by one step. The control unit 18 outputs a confirmation sound of "Pit" at the volume level after the change, and overlays and displays a level notification window W5 indicating the current volume near the center of the first menu screen. The user listens to this confirmation sound, determines whether it is appropriate, and further touches the volume increase button 41a or the volume decrease button 41b to adjust the volume if necessary. The volume is adjusted in 8 steps from 0 to 7, and the initial value is set to 5. When the volume level is set to 0, no voice alarm is issued. Also, when the volume increase button 41a is further touched in the state where the current volume level is the maximum "7", the control unit 18 outputs a warning sound of "Bubbu" without changing the volume level. In this way, since the volume increase button 41a and the volume decrease button 41b are arranged on the first menu screen, the user can easily change and set the volume level by simply touching either button, enabling immediate setting.

[0076] When it is detected that the standby change button 41d has been touched (see Fig. 7(a)), the control unit 18 displays a standby change screen shown in Fig. 7(b) on the display unit 4 instead of the first menu screen. When it is detected that the registration button 41f has been touched (see Fig. 7(c)), the control unit 18 displays a registration screen for registering a location or the like at an arbitrary place shown in Fig. 7(d) on the display unit 4 instead of the first menu screen. In this way, the control unit 18 displays a screen for performing predetermined selection, registration, etc. in accordance with the touch of a button.

[0077] When the top button 41g is further touched, the control unit 18 displays the standby screen displayed in the normal state, which is the top screen. Also, when there is no operation for a predetermined time after the control unit 18 displays the first menu screen, it performs a process of returning to the display of the standby screen. The predetermined time is, for example, 3 seconds.

[0078] When the control unit 18 detects that the setting button 41c has been touched (see Fig. 5(b)), it displays the setting menu screen, which is the top screen of the second menu screen shown in Fig. 5(c), on the entire display screen of the display unit 4. In this embodiment, the items to be set are divided into three groups, and specific settings are made from the setting menu screens provided for each group, so that the target item can be easily and smoothly reached and the setting can be performed. The three groups are "System", "Function", and "Option". The system is a setting item related to the entire radar detector 1. For example, it is good to assign setting items that are often not changed as long as they are installed in the vehicle once set, or initial settings that are performed at the beginning of use. The setting items belonging to this system include, for example, brightness, base color, car type, etc. Specifically, for example, there are 9 items listed in Fig. 8.

[0079] The function is a setting item for setting individual functions such as changing the opening or mode, and it is good to assign those that are sequentially changed during normal use. The setting items belonging to this function include, for example, the mode for specifying the warning target to be notified, the warning pattern for setting what kind of warning display to make, etc. Specifically, for example, there are 6 items listed in Fig. 9. The photo frame setting is for setting the image displayed on the standby screen and is a display setting in the standby function. Since it is a display mode setting in the notification function, both are regarded as setting items belonging to "Function".

[0080] The option is a setting item when an optional product such as an OBDII adapter is connected. For example, it is divided into an OBD setting that is only displayed when the OBDII adapter is installed and a WLAN setting that is only displayed when an SD card with a wireless LAN function is installed. The OBD setting and the WLAN setting each have a plurality of setting items.

[0081] The setting menu screen is laid out with three buttons, namely the system button 42a, the function button 42b, and the option button 42c, arranged horizontally in three groups. The top button 42d is placed small at the lower left, and the title display section 42e is placed at the upper left. The title display section 42e shows "Settings", indicating that it is the setting menu screen. When the control unit 18 detects that the top button 42d has been touched, it switches to the top standby screen display (see Fig. 5(a) etc.).

[0082] When the area of the system button 42a is short-pressed on the setting menu screen (see Fig. 10(a)), the control unit 18 displays a system setting screen as shown in Fig. 10(b) on the entire display screen of the display unit 4. As will be described later, the system setting screen is composed of three pages, and the first page is displayed. This system setting screen has a title display section 43a at the upper end, and uses many areas below the title display section 43a to arrange a predetermined number of multiple setting item display areas 43b vertically side by side. Cursor buttons 43c are arranged vertically at the right end, a page display section 43d is arranged in the center of the right end, and a return button 43e and a top button 43f are arranged below the left end, taking this layout.

[0083] When the return button 43e is touched, the control unit 18 performs a process of returning the screen display to the previous screen, and here, the setting menu screen is displayed. When the top button 43f is touched, the control unit 18 switches to the display of the standby screen. The title display section 43a shows "System Settings", indicating that it is the system setting screen.

[0084] The setting item display area 43b is formed horizontally, provided with a title display section 43b' for displaying the title of the setting item on the left end side thereof, and provided with a setting content display section 43b'' for displaying the current setting content on the right end side. A predetermined number of the setting item display areas 43b having such a configuration are arranged vertically. The predetermined number is four in this embodiment. On the system setting screen of the illustrated page, in the uppermost setting item display area 43b, "Brightness" is displayed as the title, and "Normal" is displayed as the setting content. As shown in FIG. 8, the possible setting values for the setting item "Brightness" are three values, namely, "Dark", "Normal", and "Bright", and here it shows that "Normal" is the current setting content as per the initial value.

[0085] In this embodiment, since the setting content display section 43b'' is provided at the right end of the setting item display area 43b of the system setting screen, the current setting content can be known without switching the screen and entering, for example, a setting change screen of a lower layer. The user can easily know whether to change the setting content for the setting item and there is no need to switch the screen for confirmation. The user can check the displayed current setting content and, if wanting to switch, can enter, for example, a lower setting menu screen, so it is preferable because the setting for the necessary setting item can be quickly performed. Further, since the title and the setting content are displayed in pairs in a single-line display, the relationship therebetween can be understood at a glance.

[0086] The predetermined number is set to a maximum of four. Thus, the setting item display area 43b is characterized in that four lines are displayed on one screen. By displaying four lines in this way, while ensuring the visibility of the information displayed in the title display section 43b' and the setting content display section 43b'', the number of items that can be displayed on one screen can be increased, and the number of screens for displaying the setting items belonging to one group can be suppressed. In this embodiment, in principle, the setting can be accommodated within three screens. For example, since there are nine setting items belonging to the system, the system setting screen can be composed of three screens (see FIG. 11(a)). The switching to each screen is performed by touching the cursor button 43c.

[0087] In this example, since it is composed of three screens, the whole can be checked with a small number of touches, and the target selection item can be found. Therefore, from the setting menu screen, enter the system setting screen one level lower, immediately check the content, make settings as necessary, and then return to the upper screen by touching the return button 43e or the top button 43f.

[0088] Also, as will be described later, the setting value candidate display section 44b also serves as a button for transitioning to the lower setting change screen. Then, this button is touched and selected with a finger or the like. By limiting it to 4-line display, it is possible to accurately touch the desired setting value candidate display section 44b without accidentally pressing a plurality of adjacent setting value candidate display sections 44b above and below at the same time. Furthermore, in this embodiment, although the display section 4 uses a 3.5-inch size, by adopting 4-line display, for example, even a 2.8-inch size can ensure visibility and operability without accidental touch.

[0089] When a setting item display area 43b other than the setting content display section 43b″ is touched, the control unit 18 displays a setting change screen for the touched setting item. For example, when the setting item display area 43b of "brightness" in FIG. 10(b) is touched, a setting change screen for the brightness shown in FIG. 10(c) is displayed. The layout of this setting change screen is the same as that of the system setting screen. A title display section 44a is arranged at the upper end, and using many areas below the title display section 44a, a predetermined number of setting value candidate display sections 44b are arranged vertically side by side. Cursor buttons 44c are arranged above and below the right end, a page display section 44d is arranged in the center of the right end, and a return button 44e and a top button 44f are arranged below the left end. The title display section 43a displays "Brightness Selection" indicating that the setting item is "brightness".

[0090] The maximum number of setting value candidates to be arranged on one screen is set to 4. By limiting it to 4, each setting value candidate display section 44b can have a vertical length, ensuring good visibility and good operability such that a desired one of the setting value candidate display sections 44b can be touched. Since the candidates for the setting value of the setting item "brightness" are three, namely "dark", "normal", and "bright", the fourth line is blank and it fits on one screen. When there are five or more of these setting candidate values, a plurality of screens are prepared and the screens are switched by touching the cursor button 44c.

[0091] In the present embodiment, the number of setting candidate values to be set is limited to within four so that it fits on one screen. As a result, the user can list up the candidates for the selectable setting values in the setting item to be set processing on one screen and confirm them at a glance, and it is good that the desired one can be selected and set. For example, if a large number of five or more candidates are prepared, although more user-preferred settings can be made, it is necessary to take a lot of trouble to switch the screens while confirming the candidates for the setting values, and the setting process becomes complicated. As a result, it often remains at the initial value without setting, but in the present embodiment, by narrowing down and reducing the number of candidates for the selectable setting values and the number of setting items, it becomes easier to find the target setting value and it can be set with a small number of processing steps.

[0092] As shown in FIG. 8, for example, for the setting items "base color" and "cartype", five candidates for the setting values are prepared. Therefore, when such a setting item is selected, two setting change screens are displayed. For these setting items as well, it is more preferable that the candidates for the setting values are four or less so that they can be displayed on one screen.

[0093] The setting of the set value for the setting item is performed while displaying the desired set value candidates. This setting is performed by touching the set value candidate display section 44b. As shown in FIG. 10(c), the control unit 18 displays a line 44h below the frame that partitions the area of the set value candidate display section 44b corresponding to the current setting content. In the figure, since "Normal" is selected, the line 44h is displayed in the central set value candidate display section 44b corresponding to the "Normal". In this state, for example, when the upper "Dark" set value candidate display section 44b is touched, the control unit 18 changes the setting content for the selected item "Brightness" to "Dark" and performs a process of displaying a line in the upper "set value candidate display section 44b".

[0094] When detecting that the function button 42b has been touched on the setting menu screen shown in FIG. 5(c), the control unit 18 displays the function setting screen (1 / 2) shown on the left side of FIG. 11(b). As shown in the figure, the function setting screen has the same layout as the system setting screen, with the title "Function Setting". In response to the touch operation of the cursor button 44c, the control unit 18 switches and displays the function setting screen (1 / 2) and the function setting screen (2 / 2). As shown in the figure, in the 4-line setting item display area 43b on the first function setting screen, [Mode] [Alarm Pattern] [Opening] [Photo Frame Setting] are displayed from the top. At the right end of the setting item of [Mode], [Normal] is displayed as the initial value.

[0095] When detecting that the option button 42c has been touched on the setting menu screen shown in FIG. 5(c), the control unit 18 displays the option setting screen. Although not shown in the figure, the option setting screen has the same layout as the "system setting screen" and the "function setting screen", with the title "Option Setting", and has a layout in which [OBD] [WLAN] are displayed in two areas from the top in the 4-line display area.

[0096] Then, when the control unit 18 detects that the button portion of [OBD] has been touched on such an option setting screen, it displays the OBD setting screen (1 / 2) shown on the left side of FIG. 11(c). Further, when the control unit 18 detects that the button portion of [WLAN] has been touched, it displays the WLAN setting screen (1 / 3) shown on the left side of FIG. 11(d). The control unit 18 switches the displayed screen in response to a touch operation on the cursor button 44c on each setting screen.

[0097] As described above, in the present embodiment, the immediate first menu screen displays all selectable item buttons on one screen, and the second menu screen for non-immediate settings restricts the number of displayed setting items to a reference value or less on one screen. In this way, on the immediate first menu screen, the operation buttons selectable on the first menu screen are listed, so that the user can immediately select the target operation button and perform the desired process. Further, on the second menu screen, a layout of four rows with a long and narrow button area arranged vertically is adopted, but the first menu screen is characterized in that it does not adopt the basic arrangement layout of arranging six buttons (seven including the back button) vertically like the second menu screen. Arranging six to seven buttons vertically would result in two pages and they could not be listed all at once, so they cannot be shown in a series and pressed immediately without scrolling. However, by arranging them appropriately vertically and horizontally and displaying them on one screen as in the present embodiment, the effects of the above-described embodiment are exhibited.

[0098] Since the number of items displayed on the second menu screen is limited, the setting items displayed on the second menu screen are easy to see, the setting item for the intended purpose is easy to find, and the intended setting item can be surely selected. In particular, when the number of items to be restricted is exceeded, it is preferable to provide a plurality of sheets and a switching function. In the embodiment, the switching function is realized by the cursor buttons. By restricting the number of items displayed, the number of sheets of the second menu screen increases, but since there is no immediacy, it is possible to search slowly. In particular, when the selection of the setting item is made touch-sensitive to the display screen, since the number of items displayed is restricted, for example, the area of one setting item can be enlarged or the distance from the adjacent setting item can be increased, so that it is possible to prevent accidentally touching a different setting item or pressing a plurality of adjacent setting items simultaneously, which improves the operability, and this is preferable.

[0099] (Automatic return function to the standby screen, etc.) As described above, when touched on the standby screen (see FIG. 5(a) etc.), the control unit 18 displays the first menu screen (see FIG. 5(b) etc.), but when there is no screen operation for a certain period of time, the control unit 18 has a function of returning to the display of the original standby screen. The certain period of time is preferably, for example, 3 seconds.

[0100] In the immediate first menu screen, for example, selectable operation buttons are listed, so the user can immediately determine whether there is an immediate item to be processed now by looking at the first menu screen. If there is no item, it can be left as it is and automatically return to the standby screen. Since the first menu screen is a button for performing an immediate process, a user who wants to perform various processes and settings should press the button for the next operation if there is a certain period of time such as 3 seconds, so it may be automatically returned to the standby screen.

[0101] Furthermore, after the system settings screen is displayed when the settings button 41c is pressed on the first menu screen, it is advisable not to transition back to the original screen even if there is no screen operation for a certain period of time. Since the second menu screen is for making settings that do not require immediacy, one may need to consider how to make settings by looking at the displayed screen, and there may be no screen operation for a certain period of time. If one returns to the original screen in such a case, it is necessary to perform an operation to transition back to the screen for processing again, which becomes cumbersome. Therefore, by not allowing automatic return, one can consider carefully and perform operations reliably, which is good.

[0102] Also, it has a radar cancellation function that stops the alarm when the screen is touched during an alarm associated with radar wave reception. For example, if the screen is touched for such a radar cancellation function and it is set to transition to the first menu screen associated with the screen touch, for the person who wants to stop the alarm, the display of the first menu screen is an obstructive operation and there is a demand to immediately return to the original standby screen. Therefore, it is advisable to set it to return in a relatively short fixed time, for example, 3 seconds. And for those who want to make settings later, since there are 3 seconds, they will press the button for the next operation, so it is okay not to have automatic return.

[0103] Also, when the screen is touched during a radar alarm, the alarm is stopped and the radar is cancelled, but it is advisable not to display the first menu screen. The touch during the alarm can be an operation for alarm cancellation, and by not having a screen transition, the standby screen can be continuously displayed, which is good.

[0104] (Function for changing setting values using the setting content display section 43b″) In the above-described embodiment, on each setting screen, a predetermined number of setting item display areas 43b are arranged vertically, and each horizontally long setting item display area 43b is provided with a title display part 43b' for displaying the title of the setting item and a setting content display part 43b'' for displaying the current setting content, so that the current setting content can be confirmed while maintaining such a setting screen. In order to change the setting value of the setting item, it is necessary to touch a predetermined position of the setting item display area 43b to switch to the display of the setting change screen.

[0105] Each setting screen provided with the setting item display area 43b may also be provided with a function for changing and setting the item value of the setting item. For example, as a function for changing and setting the setting value, when an operation is performed on the setting content display part 43b'' that displays the current setting content, it is preferable to have a function for switching the current setting content without displaying the setting change screen. The operation on the setting content display part 43b'' may be, for example, a touch on the said part.

[0106] This function is preferably applicable when there are two to three candidates for the setting value, and particularly preferably two. For example, in the case of two, when it is detected that the setting content display part 43b'' has been touched, the control unit 18 sets something other than the current setting content as the current setting content and switches the display of the setting content display part 43b''. For example, as shown in FIG. 9, since the setting values of the alarm patterns are two types, namely, "CG live-action alarm" and "telop alarm", for example, when the setting content display part 43b'' is touched in a state where "CG live-action alarm" is displayed as the initial value, the setting value is set to "telop alarm", and "telop alarm" is displayed on the setting content display part 43b''. Further, when the setting content display part 43b'' is touched from that state, the setting value is set to "CG live-action alarm", and "CG live-action alarm" is displayed on the setting content display part 43b''. This is also applicable to the case of a setting for turning a certain function ON / OFF.

[0107] Also, when there are three or more set values, it is preferable to adopt a toggle method in which each time the setting content display section 43b″ is touched, the set values are changed one by one in a predetermined order. Also, in the case of three or more, for example, if the candidates for the set values to be switched in a toggle manner with the touch of the setting content display section 43b″ are made fewer than the candidates for the selectable set values displayed on the lower setting change screen, the number of touch operations required to go around once can be reduced, which is good in that it eliminates annoyance, but it is preferable to make them the same. When reducing the number of the toggle type, it is preferable to set so that representative ones are displayed. With such a configuration, even without transitioning to the lower-level setting change screen, the setting of the setting content of the setting item can be performed by operating the setting content display section 43b″. Therefore, there is no need to repeatedly perform screen transitions between the lower setting change screen and the setting screen in which four setting items are displayed, and the operation is also simple in this embodiment because it only requires touching a predetermined position on the setting screen once, resulting in good operability, which is preferable.

[0108] Furthermore, when the number of candidates for the set value is equal to or more than a reference value, it is preferable to prevent the setting content from changing even if there is an operation on the setting content display section 43b″. Often, the user does not know how many candidates for the set value there are. If there are a large number of candidates, there is a risk that even if the user tries to touch and the setting content changes, it may not be the desired setting content. Therefore, when the number of candidates for the set value is equal to or more than the reference value, for example, by preventing the setting content from changing even with a predetermined operation such as touching the setting content display section 43b″, it is possible to suppress the occurrence of such a situation. Furthermore, when the change of such setting content is prevented, it is more preferable to transition to the lower setting change screen.

[0109] (Display on the setting content display section 43b″) The display information for specifying the setting value to be displayed on the setting content display section 43b″ and the display information for specifying the setting value to be displayed on the setting value candidate display section 44b of the lower-level setting change screen may be the same. However, the display information for the setting content display section of the setting menu screen and the display information for the setting value candidate display section of the setting change screen are each given a different data structure, and it is preferable that each display information meaning the same content has a simpler expression for the setting content display section. The simpler expression may be, for example, a mark or symbol, but it is better to use a term with a small number of characters, and when reducing the number of characters, it is better to use an abbreviated form.

[0110] In particular, the setting content display section 43b″ is provided in a partial area within the setting item display area 43b, and is narrower than the display area of the setting value candidate display section 44b, especially in the horizontal length. Therefore, for example, if the number of characters of the setting content becomes long, it may not fit within the display area and the meaning content may become difficult to understand. Thus, considering that such a display area has a short horizontal length, by using display information that can be understood with short content, the setting content displayed on the setting content display section 43b″ can be easily understood, and it is possible to determine whether it is necessary to change the setting. On the other hand, since the setting value candidate display section 44b has a long horizontal length, the display information is made to have a sufficient length so that the content can be easily understood when the setting change screen is displayed, and after the user understands the content of the setting value, the user can make a setting according to their preference.

[0111] When currently displaying the setting content in characters, it is preferable that the display of the setting content display section 43b″ is created with one picture instead of a font. Since the setting content display section 43b″ has a small display area, it is difficult to see when using a font. However, by displaying each setting content as one picture, the character part becomes neat and easy to see, which is good.

[0112] On the setting menu screen, the current setting content can be displayed within the display area of the setting items, and the user can understand the content more or less. And in the state where the actual setting menu screen is transitioned to, the setting content as a selection candidate is correctly displayed, so that the user can correctly understand the content.

[0113] (Mode setting function) Also on this function setting screen, when it is detected that the setting item display area 43b is touched, a setting change screen for the touched setting item is displayed. Although not shown in the figure, when [Mode] is touched, a setting screen for the mode (displaying selection candidates of Normal, All On, and Manual from the top) is displayed. As shown in FIG. 12 for the correlation between some setting items and setting values, "Normal Mode" and "All On Mode" are fixed settings and the user cannot individually set ON / OFF for each setting item. On the other hand, when [Manual Mode] is selected, all setting items can be individually configured to change the setting values. Although specific illustrations are omitted, the setting items are divided into three groups of [Radar / Wireless], [GPS], and [Others], and the setting items are configured to be selected and set in units of groups.

[0114] To realize such a configuration, when the manual mode is selected, the control unit 18 first displays a screen with three selection buttons of [Radar / Wireless], [GPS], and [Others]. When any button is touched, a setting menu screen with four setting items belonging to that group arranged vertically is displayed. When one of the four displayed setting items is touched, the control unit 18 has a function of, for example, displaying a setting change screen for the touched setting item or changing the setting content based on the touch on the setting content display unit 43b″.

[0115] There are many setting items whose set values can be changed in the manual mode. As described above, even if they are divided into three groups of [Radar / Wireless], [GPS], and [Others], especially for "GPS", since there are many warning targets based on location information, the setting menu screen for GPS exceeds 4 pages. In this embodiment, in order to conform to the principle of within 3 pages, for example, without dividing them into [GPS1], [GPS2], [GPS3], etc., the number of setting menu screens is made to exceed the standard number of 3 pages as an exception. If the warning targets based on location information are divided and distributed among multiple GPS groups so that they can fit on 3 setting menu screens, the user will not know which items belong to which GPS group, so they need to view each group in order to find the group they belong to, which actually makes it less user-friendly. Therefore, GPS is grouped into one group.

[0116] Furthermore, the initial value of the "manual mode" is set to the content of the minimum mode that turns on the necessary minimum number of setting items. Therefore, if the manual mode is selected and used with the initial value, it will be an operation setting with few warnings and not the noisiest, which is fine. And when the user wants to make individual settings according to their preferences, they can select the manual mode and set each selection item individually to set the warning conditions and types of warnings according to their preferences. The content once set is saved as it is. For example, when the manual mode is selected again after selecting another mode, the ON / OFF, etc. of each setting item will be the content set immediately before saving. In this embodiment, the manual mode combines two types of modes: a mode for literally manual setting and a minimum mode for performing the necessary minimum number of warnings.

[0117] (Explanation pop-up display function) When a first operation is performed on a setting item displayed on the second menu screen, a function for performing processing for setting the setting item is provided, and when there is a second operation different from the first operation, an explanation pop-up screen for explaining the content of the setting item is provided. The first operation may be a short press, and the second operation may be a long press. As the function for performing processing for setting, for example, a function for displaying another screen or changing and setting the setting content based on a touch on the above-described setting content display unit 43b″ may be used.

[0118] The explanation pop-up screen has a function of displaying, on the display screen, for example, an explanation regarding the selected and displayed setting item, for example, a general explanation / description about the long-pressed item, and explanations of the content of the setting such as "when setting to ○○, it will move like this" and "when turned on, it will give such an alarm". In this way, for example, when the user does not understand the content displayed on the display screen of the display unit 4, the user long-presses. When the control unit 18 detects the long press, the corresponding explanation pop-up screen is displayed. Therefore, the user can check the display content of the explanation pop-up screen and can instantly know the content they want to know without taking out the instruction manual and searching for the corresponding page. When the "setting item" is actually displayed and the "setting item" is long-pressed to display an explanation about the "setting item", the user can understand what settings will be made when operating the "setting item", can easily determine whether the setting is necessary for themselves, and if necessary, can immediately change the setting.

[0119] For example, as shown in FIG. 13(a), when it is detected that a setting item display area 43b for displaying a predetermined setting item (in the example of the figure, "brightness") is long-pressed while a system setting screen, which is an example of the second menu screen, is being displayed, the control unit 18 displays, on the display unit 4, an explanation pop-up screen as shown in FIG. 13(b), for example. Also, for example, in the system setting screen shown in FIG. 13(a), when it is detected that the setting item display area 43b of "base color" is long-pressed, the control unit 18 displays, on the display unit 4, an explanation pop-up screen as shown in FIG. 13(c), for example.

[0120] The explanatory pop-up screen has a layout including a content explanation display section 45a arranged in the main display area R1 of the entire display screen of the display section 4, and a close button 45b arranged in the lower right within the content explanation display section 45a. This explanatory pop-up screen is set to be displayed across the entire display section 4. By this display, the screen that was previously displayed (here, the system settings screen) becomes invisible. The invisible state may be, for example, that while displaying the previously displayed screen, the explanatory pop-up screen is overlaid on that screen for display. However, it is better to display only the outer surface of the explanatory pop-up without displaying the previous screen before switching the screen display. As shown in the figure, the content of the explanatory text displayed in the content explanation display section 45a provides a general explanation and does not show specific settable values, etc.

[0121] This explanatory pop-up screen is prepared for all the second menu screens, including, for example, the settings menu screen which is the top screen of the second menu screen shown in Fig. 5(c), for each item arranged on each screen, and stored in the radar detector 1. The control unit 18 calls up the explanatory pop-up screen for the item that has been long-pressed and switches the display to the display section 4. For example, on the settings menu screen, when the system button 42a is long-pressed, the control unit 18 switches the display to the explanatory pop-up screen explaining the system shown in Fig. 13(d). When the function button 42b is long-pressed, the control unit 18 switches the display to the explanatory pop-up screen explaining the function shown in Fig. 13(e). When the option button 42c is long-pressed, the control unit 18 switches the display to the explanatory pop-up screen explaining the option shown in Fig. 13(f). In each figure, the explanatory text displayed in the content explanation display section 45a is specifically exemplified, but it provides a general explanation and does not show specific belonging setting items, etc.

[0122] When it is detected that the close button 45b has been touched while the explanatory pop-up screen is being displayed, the control unit 18 cancels the display of the explanatory pop-up screen and displays the screen that was displayed immediately before.

[0123] Also, as described above, on the second menu screen, in principle, an explanatory pop-up screen is prepared for all items, and it has a function of displaying the corresponding explanatory pop-up screen based on a long press on the screen. However, for the back button and the top button on the second menu screen, it is characterized in that no explanatory pop-up screen is prepared. Users who operate those buttons to return to the top screen or the immediately previous screen tend to long press them even during normal operations, such as continuously pressing those buttons until the screen switches. If an explanatory pop-up screen is displayed due to such a long press, it is an unexpected process for the user and is rather troublesome. Furthermore, for the back button and the top button, their contents can usually be understood, and it can be said that explanations by an explanatory pop-up screen are unnecessary. Therefore, in this embodiment, as described above, for the back button and the top button, no explanatory pop-up screen is provided, and they are configured not to display an explanatory pop-up screen even when long pressed.

[0124] An explanatory pop-up screen may be prepared on the standby screen and the first menu screen as well. However, in this embodiment, on those screens, the explanatory pop-up screen is not displayed even when long-pressed. The items selected on the first menu screen are buttons for selecting and instructing what to do immediately, such as those with immediacy, so the user has a strong desire to perform the immediate processing, and may accidentally long-press by continuously pressing even during normal operations. For example, the volume up button 41a and the volume down button 41b are buttons for the immediate setting of increasing or decreasing the current volume. For example, the setting button 41c is a button for immediately transitioning to the second menu screen because the user wants to make some kind of setting, and the registration button 41f is also a button for immediately transitioning to the registration menu screen to register the current point. In any case, it is easy to keep pressing each button until transitioning to the screen for performing each process. In such a case, it would be troublesome if the explanatory pop-up screen were displayed, so the setting is such that the explanatory pop-up screen is not displayed on the first menu screen. Also, like the above-described back button and top button, these buttons have content that is easy to understand and are items that do not require much explanation on the explanatory pop-up screen, so in this embodiment, the setting is such that the explanatory pop-up screen is not displayed.

[0125] On the other hand, for example, after touching the setting button 41c and the screen display transitions to the second menu screen, there are many cases where, for example, when parked, there is time available. As described above, to provide an explanation to the user using the explanatory pop-up screen and perform appropriate settings, explanatory pop-ups are prepared for all setting items except for the screen transition buttons such as the back button and top button.

[0126] Also, on the standby screen, for example, the screen is touched to cancel the radar, but the user tends to keep pressing until it is canceled. Considering such an event as a long-press and finding it troublesome if the explanatory pop-up screen is displayed, the setting is such that the explanatory pop-up screen is not displayed by long-pressing on the standby screen as well as on the first menu screen.

[0127] (Car type setting function) In this embodiment, for example, as the setting values of "car type" prepared in the second setting item display area 43b from the top in the system setting screen shown in FIGS. 10(b) and 13(a), as shown in FIG. 8, five types of "compact car", "sedan 1", "sedan 2", "SUV", and "minivan" are prepared. When this setting item display area 43b is touched, the control unit 18 displays a setting change screen for the car type, and the car type is set by a touch operation on this screen. By setting the car type in this way, as shown in FIG. 14, the shape of the schematic diagram 50 of the own vehicle displayed on the standby screen and the display mode of the wheel 51 are made to match the set car type. By doing so, the user can feel as if their own vehicle is displayed, which is good and makes them happy. FIG. 14(a) shows the standby screen for "compact car", FIG. 14(b) shows the standby screen for "sedan 1", FIG. 14(c) shows the standby screen for "sedan 2", FIG. 14(d) shows the standby screen for "SUV", and FIG. 14(e) shows the standby screen for "minivan". Also, although specific illustrations are omitted, with the setting of this car type, the shape of the vehicle displayed on the accelerometer also changes.

[0128] [CG & Real Photo Warning] FIG. 15(a) shows an example of the operation timing of the warning by the GPS warning function. As described above, the control unit 18 displays the standby screen normally displayed on the display unit during the running of the own vehicle 62 or the like. Then, the control unit 18 periodically accesses the database 19 based on the current position, and when the distance between the warning target 61 and the own vehicle 62 reaches the approach warning start distance stored in the database 19, it starts a switching warning to the map screen. Then, the control unit 18 reads out the data of the CG or photo of the warning target 61 from the database 19 according to the distance between the own vehicle 62 and the warning target 61, displays it in the warning image display window W3, and displays the information about the warning in the message window W4 (see FIG. 15(b) etc.).

[0129] In the present embodiment, a first warning for displaying a moving CG stored in the database 19 (see FIG. 15(c) etc.) and a second warning for displaying a real image obtained by photographing an image corresponding to a scene including a warning target (see FIG. 15(d) etc.) are provided. After outputting the first warning to the warning image display window W3, the second warning is output. After attracting the user's attention with the moving CG in the first warning, an image corresponding to the scene including the warning target in the second warning is displayed, so that it is easy for the user to recognize the warning content.

[0130] When the warning start distance is reached, the control unit 18 controls the LED light emitting unit 6 to blink in a predetermined emission color. The predetermined color is any one of red, yellow, green, and blue according to the type of warning target. As will be described later, it is the same color as the background display color in the message window W4 and the base color of the target icon 35 drawn on the map of the warning target. The same color is preferably a color of the same color system, but it is even better to be the same color. When starting the blinking emission of the LED light emitting unit 6, the control unit 18 is preferably performed until the warning conditions are violated, such as when the distance between the host vehicle 62 and the warning target 61 passes through 0 or the distance is separated by a predetermined distance or more.

[0131] The moving CG is a CG corresponding to the type of the warning target. For example, as shown in FIG. 16, from a state of overlooking a street scene including the warning target 55 from afar (FIG. 16(a)), it is gradually enlarged and zoomed in so that the area occupied by the warning target 55 in the screen becomes larger, and it approaches the warning target (FIGS. 16(b) to (h)). Finally, it is preferably moved so that the warning target 55 comes to the center of the screen. By making such a movement, it is good because it becomes easier for the user to understand what kind of warning target it is. Also, instead of reproducing approaching while driving on the road, for example, from a state of being seen from above, it gradually descends and approaches, wraps around, and rises from the front, etc., so that it is a video that makes the warning target 55 stand out. It is good to superimpose and display an indication icon 56 indicating the position of the warning target 55 in the CG image. In the illustrated example, the indication icon 56 is initially a rectangular frame, and as it approaches and expands with respect to the warning target, the whole becomes annular and is deformed to be thick and prominent. By drawing the indication icon 56 in this way, it becomes easier to pay attention to the warning target 55 in the screen, and it becomes easier to recognize its type.

[0132] Furthermore, for the moving CG, the entire part other than the warning target 55 of its window is covered with a translucent color that is the same as the emission color of the LED light emitting part 6 from the middle, and the opacity of the color covering the entire part other than the warning target 55 is gradually increased. By doing so, it is more preferable because the warning target gradually floats up. By unifying the CG, the LED light emitting part 6, and the background color of the message window W4, it is good because the degree of emergency can be understood without being cumbersome. In the illustrated example, since the warning target is the LH system, it is unified in red.

[0133] The real image displayed following the playback of the moving CG is preferably an image that shows the view from the driver's seat of a moving vehicle. In this embodiment, a real image consisting of image data captured at the actual location where the warning target is installed so that the warning target is reflected therein is used. Also, it is not limited to such a real image. For example, an image created from image data such as CG showing the view from the driver's seat of a moving vehicle may be used. However, using a real image as in this embodiment is better as it increases the realism. As shown in Fig. 15(d), an instruction icon consisting of an arrow 57 indicating the warning target is drawn in the real image so that it can be immediately understood where the warning target exists in the real image. By looking at the real image displayed in the warning image display window W3, the user can confirm the scenery and the position of the warning target therein, making it easier to find the existence of the warning target from the scenery actually visible ahead during driving.

[0134] The CG shown in Fig. 16 described above is an example for cases where actual devices and equipment are specified like in the LH system. Among the types of warning targets, there are also those for which specific devices and equipment such as restricted areas are not specified. Figs. 17(a) to (i) are part of the frames constituting the CG for a restricted area, which is an example of a warning target where the specific device and equipment and its installation position and state are not uniquely specified. Fig. 17(j) shows a real image.

[0135] As shown in Figs. 17(a) to (i), starting from a state where the warning target 55 is hardly visible, it gradually zooms in, and finally changes to a state where the warning target 55 imitating a mobile speed measurement device and a police officer operating it fills the entire screen. The instruction icon 58 is a ring-shaped body whose diameter gradually changes, and the screen is covered with a semi-transparent yellow to unify it in yellow.

[0136] When there is no regular monitoring in the monitoring area, the actual image may be the image data taken at the location where monitoring is carried out as shown in, for example, Fig. 17(j). When the monitoring state is not captured, arrows 57 indicating specific locations and devices are not drawn. When there are no arrows in particular, the user can recognize that the forward view visible through the windshield during driving comes to the same location as the actual image, and that it is a place where frequent monitoring is carried out and one should drive with extra caution due to many traffic accidents and the like.

[0137] The CG with movement due to the first warning is preferably set to play a series of movements repeatedly multiple times. Since the movement is played multiple times, the first warning by the CG can also be noticed. For example, when the CG is related to the type of warning target, the type of warning target can be recognized by the first warning, and then, by displaying an image corresponding to the scene including the warning target, the actual situation can be understood.

[0138] As described above, the control unit 18 controls the warning image display window W3 to output the actual image due to the second warning following the reproduction of the CG due to the first warning. It is preferable to perform this continuously without providing a time lag between the output of the CG of the first warning and the output of the actual image due to the second warning. By doing so, by continuously displaying the actual image immediately after the CG reproduction, the relevance between the notification of the type of warning target by the CG and the notification of the actual situation by the actual image can be strengthened. Furthermore, since the CG that zooms in on the warning target is used at the end, it is possible to strongly recognize the type of warning target and understand the actual situation while still recognizing the type.

[0139] Furthermore, as shown in Fig. 18(a), the control unit 18 may be controlled to display the images of the first warning and the second warning both superimposed on the warning image display window W3 within a certain period. In the period of superimposed display, the ratio of the opacity of the CG image to the opacity of the real-shot image is gradually changed so that the appearance of the two images displayed on the warning image display window W3 smoothly transitions from the first displayed image to the next marked image. In this way, within a certain period, both images are drawn, and by gradually changing the opacity of each image, it is good that the connection and continuity between the first warning and the second warning are strengthened.

[0140] An example of such control is shown in Figs. 18 and 19. For example, in Fig. 18(b), only the CG image of the first warning is displayed on the warning image display window W3. In Fig. 18(c), the CG image of the first warning and the real-shot image of the second warning are superimposed and displayed on the warning image display window W3. In Fig. 18(d), only the real-shot image of the second warning is displayed on the warning image display window W3. Also, in Fig. 19(a), only the CG image of the first warning is displayed on the warning image display window W3. In Fig. 19(b), the CG image of the first warning and the real-shot image of the second warning are superimposed and displayed on the warning image display window W3. In Fig. 19(c), only the real-shot image of the second warning is displayed on the warning image display window W3.

[0141] The control unit 18 may be configured to repeatedly perform the process of displaying by the second warning a plurality of times after the display by the first warning. For example, as shown in Fig. 18(a), after playing the CG by the first warning, after outputting the real-shot by the second warning, after playing the CG by the first warning again, it is good to repeat the process of outputting the real-shot by the second warning.

[0142] For example, when the second warning continues to be displayed after the first warning, if it is not repeated, the display time of the second warning may become long, and the attention paid to the first warning displayed first may decrease. By displaying the first warning consisting of CG according to the type of warning target after the second warning, the first warning can also be noticed. For example, even a user who initially missed the first warning can visually recognize the first warning later and recognize the type of warning target. In particular, when the second warning is a still image, if a non-moving image continues to be displayed, it is difficult to attract attention. Especially during driving, although it is impossible to focus on the display screen of the display unit 4 of the radar detector 1, by appropriately displaying the first warning consisting of moving CG, movement can be generated in the peripheral vision of the user, and the user can be made to recognize that there is a warning target that should be noted.

[0143] The display time of the first warning may be, for example, several seconds, such as 2 to 3 seconds. With such a period of time, movement can be recognized. Also, when the user looks at the screen along with that recognition, if they wait for at most about 2 to 3 seconds, a second warning such as a real image will be displayed. So, the user can confirm the content of the second warning without staring at the screen for a long time. Furthermore, after displaying an image of the actual scenery with the real image of the second warning, by notifying the CG according to the type of warning target by the first warning, attention can also be paid to the CG, and the understanding of the type of warning target displayed in the second warning can be deepened.

[0144] Thus, when repeatedly performing the first warning and the second warning, for example, as shown in Fig. 18(a), when switching from the second warning to the first warning, even in a partial section, both images are drawn, and by gradually changing the opacity of each image, it is good to strengthen the connection and continuity from the second warning to the first warning. An example of this control is shown as follows: starting from the state where only the real image of the second warning is displayed in the warning image display window W3 shown in Fig. 19(c), passing through the state where the CG image of the first warning and the real image of the second warning are superimposed and displayed in the warning image display window W3 shown in Fig. 19(d), it is good to transition to the state where only the CG image of the first warning is displayed in the warning image display window W3 shown in Fig. 19(a).

[0145] Also, the time for giving the first warning and the time for giving the second warning are preferably the same. Also, as described above, for example, when giving an audio warning at the approaching warning distances of 2 km, 1 km, and 500 m, at the first or second warning, after repeating the CG playback by the first warning and the live output by the second warning a predetermined number of times, the warning using the warning image display window W3 is stopped and the warning image display window W3 is made invisible. When reaching the nearest approaching warning distance such as 500 m, it is preferable to continue the warning using the warning image display window W3. The continuation is preferably carried out, for example, until the warning target has passed or until the warning target conditions are no longer satisfied due to a course change or the like even if it has not passed. In such a case, it is preferable to make the warning image display window W3 invisible.

[0146] In the above-described embodiment, the live image by the second warning was a still image, but it may also be a moving image. In the case of a moving image, it is preferable to play it regardless of the vehicle speed or approaching faster than the vehicle speed. Also, since the moving CG by the first warning also becomes larger as it approaches the warning target, the playback speed of the live video of the actual vehicle is preferably set to be the same as the speed of the approaching movement in the CG. By making them the same, the continuity and unity of the first warning and the second warning can be increased, which is good.

[0147] Figs. 20 and 21 show an example of notification of warnings and information using the message window W4. This message window W4 is a window for displaying various warnings during warnings or notifications, and is displayed overlaid on the map in the same manner as the warning image display window W3. With the display of this message window, no control is performed to shift the display position of the map or reduce the display area of the map. The user can check the necessary information by looking at this message window W4. Since the display position of the map is not shifted and the display area of the map is not reduced, the map on the display unit 4 and the position of the own vehicle on the map do not change, so it is easy to view. When the own vehicle icon 31 is displayed at the lower center of the display unit 4 in the heading-up display, the display positions of the warning image display window W3 and the message window W4 are on the left or right side of the own vehicle, and further, they are arranged at a predetermined distance from the own vehicle position. Therefore, the map information hidden by the window is not important because it is not the place where the currently traveling own vehicle will go immediately after that. Furthermore, regardless of the display / non-display of the warning image display window W3 and the message window W4, the display area of the map screen is the entire screen of the display unit 4, and it is good because a large area can be secured.

[0148] The warning information using the message window W4 is appropriately set according to the level of the urgency of the warning target, and four types of background colors are prepared according to the level of the urgency: red → yellow → blue → green (from high level to low level). Although the explanation is in a bit of a jumbled order, this background color is the same as the emission color of the LED emission unit 6, the base color of the target icon 35, etc. For the "Severe Caution" target with the highest level of urgency such as a loop coil, it gives a warning with a red background, and displays the type name of the warning target and the radio wave reception level in a level display. For example, Fig. 20(a) is an example of the display layout when the warning target is "Regulatory radar wave", and it takes a layout where a warning target type display section 60a (displays the type of regulatory radar wave), a reception level display section 60b (1 (low) - 5 (high)), and a current speed display section 60c are arranged. The background color is red. Fig. 20(b) is an example of the display layout when the warning target is "GPS target", and it takes a layout where a warning target type display section 60a (displays the type of GPS target), a speed limit display section 60d (displays the speed limit at the position of the speed measuring device, etc.), a current speed display section 60e, a warning target direction display section 60f (displays the direction of the GPS target with the arrow direction), and a remaining distance display section 60g are arranged at appropriate positions. Since the speed limit and the current speed are arranged side by side in one window, it is easy to understand. The background color is red. Fig. 21(a) shows an example of a warning for a small orbis.

[0149] For the "Caution Required" target with the second highest level of urgency such as a restricted area, etc., it gives a warning with a yellow background, and counts down and displays the target name and the distance to the target. For example, Fig. 20(c) is an example of the display layout when the warning target is "Digital radio", and it takes a layout where a warning target type display section 60a (displays the type of radio) and a current speed display section 60c are arranged. The background color is yellow. Fig. 21(b) shows an example of a warning for a closed level crossing.

[0150] For the "Slight Caution" target with the third highest level of urgency ratio such as a continuous curve, etc., it notifies with a blue background, and displays the target name and the current speed. Fig. 21(c) shows an example of a notification for a police phone.

[0151] "Safety driving information" with the lowest level of urgency, such as in the ETC lane, is notified with a green background, displaying the target name and current speed. Figure 21(d) shows an example of a new emergency radio.

[0152] It is advisable to prepare such a layout using the message window W4 for each warning target. The message window W4 on the right is displayed in large characters. When looking at the warning screen, it is good to have a general understanding of the situation at a glance, which allows drivers to feel at ease while driving and concentrate on driving.

[0153] [Display function for public notice information etc.] Figure 24 is a diagram for explaining the display function of public notice information. Public notice information such as the date and time and location of traffic control is regularly announced by the Metropolitan Police Department or prefectural police stations. The speed management guidelines indicate the speed limits and traffic control policies within each prefecture based on traffic realities such as the occurrence status of traffic accidents and the need for speed suppression, and are guidelines compiled by the police headquarters. The speed enforcement guidelines clarify the routes, time zones, etc. where speed enforcement is focused based on the analysis of the occurrence status of traffic accidents and requests from local residents for general roads and expressways within the jurisdiction of each police station, based on the guidelines shown in the speed management guidelines. These are guidelines compiled by each police station. These pieces of information are stored in a storage means such as a memory card and should be updated to the latest version. Also, it is advisable to store information related to traffic, although not directly related to enforcement during, for example, Traffic Safety Week.

[0154] The control unit 18 accesses the storage means during startup or while driving and searches for public notice information, speed enforcement guidelines, and other traffic-related information around the current position or along the road being traveled. For example, when the control unit 18 displays a map screen on the waiting screen, as shown in Figure 22(a), the enforcement route 70 with public notice information is indicated by a flashing red background color, and the enforcement route 71 with speed enforcement guidelines is indicated by a flashing blue background color of the road.

[0155] When the control unit 18 enters a route with, for example, regulatory information, it displays the regulatory information screen shown in Fig. 22(b) on the display unit 4 for a predetermined time and then returns to the original screen. The predetermined time is, for example, 10 seconds. Fig. 22(b) is a regulatory information screen that displays public regulatory information and becomes a public regulatory information screen. The regulatory information screen has a date information display section 72b on the upper left side, a current time display section 72c on the upper right side, a regulatory type notification section 72d at the lower end, and an information display section 72a provided in many other areas. The acquired regulatory information is displayed on the information display section 72a. Information is displayed on this information display section 72a without scrolling. Scrolling display is cumbersome as the overall image cannot be understood without looking at it all the time, and if the beginning is missed, one has to wait for a full cycle. However, in this embodiment, by performing a batch display without scrolling, the user can efficiently obtain the information they want to know, which is acceptable.

[0156] When the information to be displayed does not fit on one page, the control unit 18 displays the first page for a predetermined time without scrolling, then switches the display to two pages, displays for a predetermined time, and when the last page has been displayed for a predetermined time, it controls to cancel the regulatory information screen and switch back to the original screen. Further, when the control unit 18 detects that the screen has been touched while the regulatory information screen is being displayed, it cancels the display of the regulatory information screen and performs a process of returning to the standby screen. By providing a function to return to the standby screen by touching the screen in this way, it is possible to cancel the regulatory information screen without waiting for a predetermined time, which is acceptable.

[0157] Furthermore, when a predetermined part of the standby screen is touched (see Fig. 22(c)), the control unit 18 displays the regulatory information screen for a predetermined time (see Fig. 22(d)). The predetermined part is set at the upper left of the standby screen. Even if the public regulatory information screen has disappeared and been missed, it can be redisplayed with a simple operation to check the content.

[0158] When a predetermined part of the standby screen is touched, if there is no regulatory information on the route during driving, the control unit 18 may not display the public regulatory information screen. This way, when the regulatory information screen is not displayed even when touched, it can be understood that the road during driving is not relevant, so it is acceptable to drive with peace of mind.

[0159] The control unit 18 causes the enforcement type notification unit 72d to emit red / blue light corresponding to the type of enforcement, so that it can be understood from the color what the information is about. The emission color is the same as the background color of the road, red for public enforcement information and blue for speed enforcement guidelines. When the type of enforcement is displayed in characters, it is known that the first one will be missed in the case of scrolling display, and it is difficult to find even if it is displayed in characters on the information display unit 72a. However, it can be intuitively understood by the color displayed on the enforcement type notification unit 72d. In particular, since the emission color is the same as the background color of the road, it is good for the user to be able to understand the type more intuitively.

[0160] [Function of issuing different warnings for the same type of warning target] Even for the same type of warning target, it is advisable to set the warning target that requires attention during passage as a specific warning target, and relax the conditions for the specific warning target to be the notification target, making it easier to be notified. The same type of warning target includes, for example, those containing the same part in the name. For example, it is advisable to distinguish and issue a warning for "Level Crossing Requiring Attention" which is of the same type as the warning target of "Level Crossing" and requires attention during passage. Examples of "Level Crossing Requiring Attention" include "Closed Level Crossing", "Level Crossing with Frequent Accidents", "Automobile Bottleneck", "Pedestrian Bottleneck", "Narrow", "School Route", etc. This "Level Crossing Requiring Attention" may use, for example, the information of "Level Crossing Road to be Improved" designated by the country and the Ministry of Land, Infrastructure, Transport and Tourism.

[0161] Group the warning target level crossings into normal level crossings and level crossings requiring attention, and distinguish and remember them. For example, by making the distance at which the approach warning starts between a level crossing requiring attention longer than the distance at which the approach warning starts between a normal level crossing, it is possible to issue a warning from a farther position. Furthermore, for example, for a normal level crossing, the target for which the approach warning is issued is within a predetermined angle θ1 with respect to the traveling direction of the vehicle, and for a level crossing requiring attention, it is θ2 (θ2 > θ1). In this way, even level crossings existing in a more oblique direction will satisfy the warning conditions and issue a warning when they are level crossings requiring attention.

[0162] For example, when there is a "non-opening level crossing" ahead on the road during driving, even if it is reported that "there is a non-opening level crossing" when approaching, for example, 200 m, there is no escape route from there and it only causes stress. Therefore, in this embodiment, by notifying at a timing earlier than that of a normal level crossing, it is possible to escape via another detour. Since a target icon of a level crossing requiring attention such as a non-opening level crossing is displayed on the map of the waiting screen, the user can determine whether it is okay to drive on the current road by looking at the relationship with the position of the own vehicle, or whether it is necessary to turn right or left, and can proceed along an appropriate passage. Also, even if a voice message adding directions such as "There is a level crossing requiring attention ○○ m ahead to the left" or "There is a level crossing requiring attention ○○ m ahead" is notified, it is okay because it is possible to know whether it is necessary to go straight ahead.

[0163] The specific warning target may have a prominent warning mode. For the prominent warning mode, for example, it is good to change the color or change the content of the voice notification. For the notification using voice, for example, two types such as "This is a non-opening level crossing, please be careful" and "This is a level crossing with frequent accidents,..." are prepared individually, and the others are grouped together like "This is a level crossing requiring attention,..." so that the number of types of notifications is reduced compared to the types of level crossings belonging to the level crossings requiring attention. By using different voice messages for the "non-opening level crossing" and the "level crossing with frequent accidents" that require special attention, it is good because it is possible to know what kind of level crossing requiring attention it is just by listening to the voice.

[0164] Also, it is advisable to use one common target icon 35 for the six types of level crossings requiring attention to be displayed on the map, and to prepare six different moving CGs to be displayed in the warning image display window W3. In the case of the target icon 35, since the display area is also small and it is difficult to distinguish the difference at a glance, it is grouped into one type. Since the warning image display window W3 has a certain display area, it is good to use different CGs to convey the content of each level crossing clearly.

[0165] Furthermore, among "level crossings requiring attention", it is advisable to relax the notification conditions for "closed level crossings" in particular and make the alarm sound earlier and more widely. For example, "level crossings with frequent accidents", "narrow sections", "bottlenecks", and "school routes" arouse stronger attention than ordinary level crossings, but one can just pass through them with caution. However, for closed level crossings only, one cannot pass through or it takes a great deal of time to pass through, so it is advisable to notify earlier. Also, for school routes and the like, it is advisable to change the alarm conditions and alarm content according to the school commute time zone and day of the week.

[0166] [Modification Example] Figs. 22 and 23 show an example of the type of each target that is the alarm target, the target icon, and the timing of alarm / notification in the GPS alarm function that alarms based on location information. Instead of or together with the explanations displayed on the above-described explanation pop-up screen, a figure explaining the timing of issuing an alarm as shown in the figure may be displayed.

[0167] Although the user does not pay much attention to the timing when the alarm sounds, it is good because it can be intuitively understood and a sense of acceptance can be obtained by showing it in the figure. Although these figures may be described in the instruction manual, they have poor linkage with the actual operation of the radar detector 1 and are often not visible, but it is good because it becomes easier to understand the alarm timing by displaying them on the display unit of the radar detector 1.

[0168] The above-described embodiments are premised on a single device, the radar detector 1. However, for example, the display of the explanation pop-up screen may be realized by another device. When realized by another device, for example, a smartphone or a communication robot may be used.

[0169] The smartphone can be used as an AR app. For example, it is advisable to take a picture of the radar detector 1, perform recognition processing based on the acquired image to identify the model, and display an explanation for that model. Also, it is advisable to use AI to provide voice notifications. For example, if there is a voice recognition function and it can recognize questions containing terms corresponding to setting items such as "What is the LH system?", it can answer the content to be notified in a description pop-up by voice. In both cases, it is good to have an explanation of the content immediately when one wants to know.

[0170] [History display function] For example, when a vehicle speed measuring device such as Obis passes by the warning target, the driver may worry, such as "Did I slightly exceed the speed?". The conventional radar detector has a function of displaying the vehicle speed of the host vehicle from ○○ m in front of Obis until it passes on the display unit, but there is a problem that the vehicle speed of the host vehicle when it has passed cannot be confirmed after passing. For example, if the driver looks at the vehicle speed displayed on the display unit 4 of the radar detector 1 when the warning target passes by, the passing speed can be confirmed. However, usually, the driver looks ahead while driving and it is difficult to focus on the display unit 4 when passing by. Even if the driver looks at the vehicle speed displayed on the display unit 4, since only the vehicle speed at the pinpoint position at the time of viewing is confirmed, there is also a problem that it is difficult to understand the tendency of driving trends such as driving state and speed changes.

[0171] The radar detector 1 has a function of recording information regarding the vehicle speed of the host vehicle when passing a predetermined warning target, and a history display function of notifying the display unit 4 of the recorded history information of the vehicle speed of the host vehicle. The predetermined warning target is preferably, for example, a speed measuring device that measures the speed of a vehicle, and particularly preferably a vehicle speed measuring device that is fixedly installed.

[0172] For example, not limited to the place where a vehicle speed measuring device such as Obis is fixedly installed, including places where mobile speed enforcement such as a restricted area is carried out, the points and areas where the vehicle speed is measured are, for example, dangerous places where it is easy to exceed the speed or where traffic accidents are likely to occur, and it is often necessary to drive safely without exceeding the speed. Among the warning targets for GPS warnings, if the warning targets that record the history information of the own vehicle speed are limited to them, when checking the recorded history information later, it is good because the driving tendency of oneself at the points and areas where safe driving should be particularly carried out can be efficiently confirmed. In particular, the place where a vehicle speed measuring device such as Obis is fixedly installed is a place where more attention should be paid to the driving speed than in the restricted area, so it is good to have a function of recording and notifying the history information only for the warning targets such as the Obis.

[0173] When "passing through the warning target" for recording the own vehicle speed, for example, it may be set within a predetermined section from when the warning target passes to Xm in front of the warning target and Ym after passing. In the present embodiment, since information regarding the own vehicle speed is recorded, the own vehicle speed at the time of passing can be confirmed after passing a predetermined warning target. Since the own vehicle speed within a predetermined section from Xm in front of the warning target to Ym after passing is recorded, not only at the time of passing but also the driving situation of the own vehicle speed in the surrounding area can be notified. During this predetermined section, the control unit 18 acquires and records the own vehicle speed obtained based on the GPS information and the "vehicle speed" included in the OBD information at an appropriate timing, and displays it on the display unit 4 as a list display at a predetermined timing.

[0174] If a function is provided to record and display the history of vehicle speed multiple times in the section from before the warning target to the warning target itself, it is beneficial as it allows the driving tendency to be understood. For example, when the warning target is a speed measuring device such as Orbis, a driving tendency of decelerating the speed below the speed limit immediately before the warning target is not preferable and is dangerous. For example, if only the vehicle speed at the time of passing is notified, both the case where the speed is decelerated to below the speed limit at the time of passing after decelerating immediately before, and the case where the vehicle is traveling below the speed limit from a relatively far distance ahead, will result in the normal outcome of "passing below the speed limit", and the dangerous driving tendency immediately before cannot be detected. In contrast, in this embodiment, by recording and displaying the speed history from a predetermined distance before the warning target, it is possible to detect a driving behavior that is not preferable in terms of safe driving, such as reducing the speed immediately before the warning target, and it is good because it can prompt attention.

[0175] For example, a driver who views the vehicle speed in the displayed predetermined section can understand their driving tendency, such as "always driving safely below the legal speed from ahead", "decelerating as approaching immediately before the warning target from a state of speed over-limit", "decelerating the speed after receiving a warning and keeping it below the legal speed", "not decelerating even after receiving a warning". This can serve as a reminder when driving later. Also, if a function is provided to record and display the speed history for a certain period of time even after passing the warning target, it is beneficial as it allows the driving tendency after passing to be understood. By recording and displaying the vehicle speed in the section up to Ym after passing in addition to at the time of passing, etc., driving tendencies such as "continuing to drive safely below the legal speed after passing", "accelerating immediately after passing and exceeding the speed limit" can be understood. Accelerating immediately after passing and exceeding the speed limit is not good, so it is good that such driving can be objectively recognized by the driver, etc.

[0176] Xm and Ym may be the same, or it may be better to make Xm longer. When the object to be warned is a fixed speed measuring device such as an orbis, its installation position is often selected in a place where it is dangerous and more attention should be paid to safe driving, such as a place where speeding is likely to occur or a place where traffic accidents are likely to occur. Therefore, it is not preferable for safe driving to only reduce the driving speed below the legal speed at the moment of passing or just before passing the speed measuring device of the object to be warned. It is necessary to reduce the speed from a farther position. Therefore, X is preferably set to a relatively long distance, and it is better to record and notify from a relatively far position.

[0177] On the other hand, for example, accelerating immediately after passing the speed measuring device and driving in a way that exceeds the speed limit is not preferable for safe driving, for example. Such a driving tendency appears at a relatively short distance compared to Xm in front of the object to be warned such as a speed measuring device. Therefore, Y can sufficiently grasp the driving tendency at a shorter distance compared to X. It is also possible to set Y = X or Y>X, but if so, a large memory capacity is required to record the speed history information. Therefore, if X>Y as in this embodiment, it is possible to appropriately record and notify the driving tendency in the sections before and after the object to be warned with a sufficient and necessary memory capacity.

[0178] X is preferably a relatively long distance, but for example, it is preferably a distance corresponding to a predetermined distance in front of the object to be warned that gives an audible notification. The corresponding distance is preferably a certain section before and after including the predetermined distance in front of the object to be warned that gives an audible notification. The certain section is preferably a short distance such as immediately before and immediately after, and particularly preferably the same. By doing so, for example, it is possible to know the driving state after the audible notification, such as decelerating to an appropriate driving speed based on the audible notification or continuing to drive at high speed without decelerating even after receiving the audible notification, and it is possible to know whether the warning of the audible notification is effectively functioning for the driver.

[0179] The predetermined distance for voice notification may be, for example, 500 m, 1 km, 2 km, etc., but it is preferable to set it as 500 m. When issuing multiple alarms, the most recent alarm is the most important. It is good because the effect of the alarm by the most important voice notification immediately before can be understood. Further, if the location where the alarm target such as a speed measuring device is installed is set as a dangerous section, for example, it is not a place where it is necessary to be more careful about safe driving in a dangerous place such as a place where speeding is likely to occur or an accident is likely to occur over a long section such as 1 km or 2 km before that, but a predetermined section close to the location where the alarm target is installed becomes a section where special attention should be paid to safe driving. In view of such a point as well, it is good to set Xm as 500 m as in the present embodiment. If it is set as 1 km or 2 km, when regularly recording the section up to the alarm target, the data capacity becomes large, which is not preferable due to, for example, the memory capacity of the memory card. However, if it is set as 500 m, there is also an advantage that the memory capacity can be reduced.

[0180] The control unit 18 equipped with the history display function of the vehicle speed etc. of the present embodiment acquires and records the vehicle speed at every predetermined distance during the recording section of the vehicle speed from Xm before a predetermined warning target to Ym after passing it. The predetermined distance may be, for example, 100 m. In the present embodiment, for example, since X = 500 and Y = 100, for the section from 500 m before passing the warning target to 100 m after passing, the vehicle speed is acquired at 100 m intervals and stored in one file. Further, the control unit 18 preferably has a function of also acquiring information related to driving and traveling, recording it in association with the vehicle speed, and notifying it. The related information may be, for example, the date and time information of travel, the reception status of GPS radio waves, information for specifying the road on which the vehicle is traveling, a photo of the actual shooting warning, the speed limit, the type of warning target, and the like. By recording the related information and simultaneously displaying the related information together with the vehicle speed acquired when displaying the history of the speed, it is possible to more detailedly and appropriately determine whether the driving was appropriate from the history of the vehicle speed. For example, when the vehicle speed is obtained based on GPS radio waves, recording the reception status of GPS radio waves can be used as an index of the reliability of the obtained vehicle speed. For example, when the reception status of GPS radio waves is good, the reliability of the recorded vehicle speed becomes high, and when the reception status is bad, the reliability becomes low. Also, for example, by recording the speed limit and simultaneously displaying the speed limit and the vehicle speed, it is possible to intuitively understand whether the vehicle is traveling below the speed limit and the degree of deviation from the speed limit.

[0181] The control unit 18 displays, on the display unit 4, the history of the vehicle speed during the recording period when passing through a predetermined warning target recorded at a predetermined timing. In the present embodiment, since the vehicle speeds before passing by 500 m and after passing by 100 m are displayed in a list, a user such as a driver who sees this can immediately tell whether a speeding violation has occurred or not. For example, the driver can know the tendency of the speed increasing or decreasing around here and the relative speed with respect to the speed limit, which can prompt safe driving for the driver and be used to arouse attention to suppress traffic accidents. For example, when passing through an SPEED TRAP while speeding, a notice will come from the police station at a later date, but it may take several months until the notice arrives. A driver who notices the existence of an SPEED TRAP after passing through it can use the history display function to check the driving history, thereby obtaining a clue as to whether a speeding violation has occurred or not, and can relieve the mental stress during the several months when it is unknown whether an actual notice will come or not.

[0182] The display of the history information such as the speed of the own vehicle recorded may preferably use, for example, the second menu screen without the above-described immediacy. As described above, for example, the control unit 18 that has detected that the standby screen has been touched switches the display on the display unit 4 from the standby screen to the first menu screen shown in FIG. 5(b), and displays the first menu screen on the entire display screen of the display unit 4. When it is detected that the setting button 41c in the first menu screen has been touched in that state (see FIG. 5(b)), the control unit 18 displays the setting menu screen, which is the top screen of the second menu screen shown in FIG. 5(c), on the entire display screen of the display unit 4. When the function button 42b in this setting menu screen is touched, the control unit 18 displays the first page of the function setting screen shown on the left side of FIG. 11(b). In the above-described embodiment, two of the four setting item display areas 43b on the second page of this function setting screen, namely, "Sound Customization" and "Screen Inversion", are used, and the lower two are left blank. However, as shown in FIG. 25(a), the second page of the function setting screen has a layout provided with setting items for history display. In the illustrated example, the title display section 43b' of the third setting item display area 43b from the top is displayed as "Orbis Passage History", and the setting content display section 43b'' at the right end of the third setting item display area 43b remains blank. In the present embodiment, since the warning target for recording the passage history such as the own vehicle speed is a speed measuring device fixedly installed like the Orbis, it is denoted as "Orbis Passage History" so that the warning target can be clearly understood.

[0183] When it is detected that the setting item display area 43b of this "Orbis Passage History" has been touched, the control unit 18 displays an Orbis passage history list screen as shown in FIG. 25(b). The layout of the Orbis passage history list screen is the same as that of the function setting screen and the like. A title display section 46a is arranged at the upper end, and a plurality of passage history list display sections 46b are arranged vertically in a predetermined number using many areas below the title display section 46a. Cursor buttons 46c are arranged above and below the right end, a page display section 46d is arranged at the center of the right end, and a return button 46e and a top button 46f are arranged below the left end. The title display section 46a is displayed as "Orbis Passage History", which indicates that it is a passage history list.

[0184] As described above, the passage history list display section 46b adopts a layout with four arranged vertically. The control unit 18 acquires the passage date and time information and the like of the recorded passage history, and displays the date and time information and the like on the passage history list display section 46b in order from the latest passage date and time information. When there are five or more recorded passage histories, the control unit 18 forms a plurality of orbis passage history list screens and displays the first one. Also, upon receiving a touch on the cursor button 46c, the control unit 18 switches the screen.

[0185] On the passage history list display section 46b, the passage date and time, information specifying the type of warning target, and information representing the speed limit at the installation location of the warning target are arranged horizontally in a row and displayed. For the passage date and time, it is advisable to add day-of-week information to the year, month, and day as shown in the figure. Adding the day-of-week information makes it easier for the user to recall when and which orbis, etc. they passed through. The information specifying the type of warning target uses a target icon drawn at a location corresponding to the installation position of the warning target on the map screen in the map screen. By using the target icon, it is possible to understand the type of warning target at a glance. In the illustrated example, in order from the top, a mark of "LC in white letters within a red circle" indicating a loop coil, a mark of "LH in white letters within a red circle" indicating an LH system, and a mark of "RD in white letters within a red circle" indicating a radar type including a small orbis are respectively displayed. The speed limit information for the installation location of the warning target is set as a mark corresponding to the speed limit traffic sign. In the illustrated example, the speed limits of 110 km / h, 100 km / h, and 80 km / h are respectively displayed in order from the top.

[0186] When the control unit 18 displays a list of each passing history on the passing history list display unit 46b, if there is an unfavorable driving trend such as exceeding the speed limit, it may be displayed in a manner different from the normal case. The different manner may be a conspicuous manner. By making it a conspicuous manner, it is good because it can be recognized without overlooking that an unfavorable driving such as exceeding the speed limit is being performed in terms of safe driving. The conspicuous manner may be, for example, a conspicuous color. For example, it is good to display the date and time information in red. In the illustrated example, the date, day of the week, and time for the second "2017 / 12 / 22 (Fri)" from the top are displayed in red. For example, as a different manner, a part of the date, day of the week, and time may be made in a different manner such as red, the outer frame of the passing history list display unit 46b may be displayed with a red line, or a line may be displayed below the date and time information as in line 44h of FIG. 10(c). However, as in this embodiment, it is good because the date and time can be made conspicuous by making the character part red, and it is particularly good to make all of the date, day of the week, and time red to be more conspicuous.

[0187] When the control unit 18 detects that the passing history list display unit 46b has been touched, it reads out information regarding the touched passing history and displays a detailed information display screen as shown in FIGS. 25(c) and (d). The control unit 18 reads out and displays the vehicle speed at each point and information related to driving and traveling stored in association therewith on the detailed information display screen. In the display layout of the detailed information display screen, in the left area of the screen, a date and time information display unit 47a, a road identification information display unit 47b, and a vehicle speed information display unit 47c are arranged in order from the top. In the right area of the screen, in order from the upper side, a GPS radio wave reception status display unit 47d, a moving direction display unit 47e, a real image display unit 47f that displays a real image of the warning target passed through, a warning target type information display unit 47g that displays the type of the warning target, and a speed limit information display unit 47h that displays the speed limit information of the warning target point are arranged. An SD output button 47i is provided below the warning target type information display unit 47g and the speed limit information display unit 47h, and a layout is adopted in which a two-dimensional code 47j such as a QR code (registered trademark) is displayed to the left of the warning target type information display unit 47g and the SD output button 47i.

[0188] The date and time information display unit 47a displays the date and time information displayed on the passing history list display unit 46b. The road identification information display unit 47b displays road identification information for identifying the road traveled, and outputs, for example, the address and the road name simultaneously vertically. Since there are people who are familiar with the road name, by outputting the address and the road name simultaneously, it becomes easier for the driver to recognize where the displayed orbis passing history was installed and what road the information was recorded while driving. If a specific location can be identified and recognized, for example, when speeding, etc., it is good because it is possible to raise awareness to be careful about excessive speed when driving on the same road and location later.

[0189] The own vehicle speed information display unit 47c displays the own vehicle speed information at each point from, for example, 500 m ahead to 100 m after passing, and displays, for example, the recorded own vehicle speeds arranged in order from the top in order from the distant position on the front side of the warning target. Since the own vehicle speeds are arranged vertically in the order of vehicle movement, it is good because the user who sees it can easily understand the situation of the speed change as approaching the orbis or the like of the warning target and the presence or absence of the speed change after passing.

[0190] When the recorded own vehicle speed exceeds a predetermined speed with respect to the speed limit, it is preferably displayed in a different display mode from others. The different display mode is preferably a conspicuous mode. The conspicuous mode can be realized with a simple configuration, for example, by displaying it in a conspicuous color. The conspicuous color is preferably, for example, red. The part where the color is changed may be, for example, the entire part of the speed and the unit like "○○ km / h", but as in this embodiment, it is good to change only the display color of the numerical part of the speed and not to change the unit part such as km / h. By changing only the color of the numerical part of the speed, the number becomes more conspicuous, and it is good because it is possible to know that the speed has been exceeded and the actual speed.

[0191] The specified speed may be, for example, set to 0 km / h and the display changed when the speed is above the speed limit, or the specified speed may be set to 1 km / h and the display changed when the speed limit is exceeded, and not changed when the speed is exactly at the speed limit. However, it is better to set it as a constant speed with a predetermined margin. The constant speed with a predetermined margin may be, for example, a speed that becomes a dangerous driving speed due to excessive speeding. In particular, only when the speed exceeds the dangerous driving speed is displayed in a prominent color such as red. When there is such a prominent color display, it can be immediately seen that there is a driving situation where the speed limit is greatly exceeded, which is good for raising awareness of future safe driving. The constant speed with a predetermined margin may be, for example, 20 km / h. A speed over 20 km / h is very dangerous and not a phenomenon that occurs, for example, when the accelerator is accidentally pressed a little too hard or the speed increases slightly on a downhill slope. Therefore, it is advisable to change the color to raise awareness when the speed is above this speed.

[0192] Although it is not preferable for the driving speed to exceed the speed limit in terms of safe driving, for example, it is hard to say that it suddenly becomes dangerous when the speed slightly exceeds the speed limit by, for example, 1 km / h compared to driving at the speed limit. For example, when driving stably near the speed limit, the speed may momentarily exceed the speed limit slightly due to the operation of the accelerator or road conditions such as a downhill slope, and the vehicle speed at the time of such a slight excess may be recorded. In such a case, if it is displayed in a prominent color as exceeding the speed limit, it is difficult to immediately tell whether it was a very dangerous driving above 20 km / h as described above or a driving that only slightly exceeded the speed limit, and it is not possible to efficiently inform that there was a dangerous driving. In some cases, the history of dangerous driving may be buried in the history of slightly exceeding the speed limit near other speed limits. In this embodiment, for example, only when there is a very high-speed and dangerous driving above 20 km / h is displayed in a different color such as red, so that the history of such dangerous driving can be surely recognized by the user. The specified speed may be set with a larger margin, for example, 30 km / h or more. However, if it is made too large, it is easy to overlook dangerous driving that does not reach that level. Therefore, it is good to set it as 20 km / h as in this embodiment.

[0193] Since the reception status of the GPS signal is displayed on the reception status display unit 47d simultaneously with other information, when the traveling speed is determined based on the GPS signal, for example, when the reception status is good, it can be understood that the displayed history information of the traveling speed is reliable and highly trustworthy. For example, when the reception status is good and all the displayed traveling speeds are below the speed limit, it can be seen that the section for which the passing history was obtained was driven safely without violating the speed limit, and when the speed limit is exceeded, it is possible to accept that a speed violation has occurred. When the reception status is poor, since the reliability of the recorded and displayed vehicle speed of one's own vehicle is low, even if the displayed vehicle speed of one's own vehicle is below the speed limit, it becomes difficult to claim that no speed violation has occurred. For example, when a speed violation is recorded in the orbis with the passing history, the user is more likely to give up.

[0194] The image data to be displayed on the real image display unit 47f is preferably the real image to be displayed in the warning image display window W in front of the warning target that has passed. By displaying the real image, the user who sees it can more intuitively recognize which history data it is when passing a warning target such as an orbis.

[0195] When it is detected that the SD output button 47i has been touched, the control unit 18 creates a text file recording the displayed detailed information and performs a process of outputting it to the memory card 11. The file name of the text file may include, for example, date and time information.

[0196] Two-dimensional codes such as QR Codes (registered trademark) may be, for example, two-dimensional codes containing information for identifying an alarm target displayed on a detailed information display screen. The information for identifying the alarm target may be, for example, location information, restricted speed, etc. For example, when photographing a two-dimensional code 47j using a portable device equipped with an application for reading two-dimensional codes such as a smartphone, the application displays the information recorded in the two-dimensional code 47j on the display unit of the portable device. By looking at the content displayed on the display unit of the portable device, the user can know information about alarm targets such as orbits related to the driving history displayed at their hand. Usually, since the display screen of the display unit of a portable device such as a smartphone is larger than the display unit 4 of the radar detector 1, it is better because the content can be more easily viewed and confirmed. In particular, as the information for identifying the alarm target, it is good to use a two-dimensional code including information for identifying the location where the alarm target is installed and information for accessing a map site on the Internet. The information for identifying the location may be, for example, longitude and latitude information. For example, by using a portable device equipped with an application for reading two-dimensional codes such as a smartphone and photographing the two-dimensional code 47j, access is made to a map site, and the display unit of the portable device displays the location of the installation position of the alarm target on the map. By doing so, the user can more accurately recognize where the alarm target is, and a warning can be given to pay attention when driving on the road where it is installed later.

[0197] [Modified Example of Driving History Information Display Function] In the above-described embodiment, each time passing a predetermined warning target, history information such as the vehicle speed is created and recorded, and sorted by date and time information to display a list. However, the present invention is not limited to this. For example, when the control unit 18 records a series of information such as the vehicle speed obtained with the passing of one warning target, it is more preferable to record the information about the same warning target in association. Recording in association may be, for example, creating a holder for each individual warning target and recording it in the holder of the passed warning target. If there is a warning target such as an orbis that passes each time, the control unit 18 groups and stores the obtained information such as the vehicle speed in the same holder. By doing so, it is possible to easily compare with the history information obtained when passing in the past for the same warning target such as the same orbis. The same warning target is regarded as a different warning target if the installation location is different. For example, when the warning target is a speed measurement device such as an orbis, it may be distinguished as one warning target for each individual speed measurement target. However, for example, it is more preferable that a plurality of speed measurement devices installed on the same road with the same road name are regarded as the same warning target. In particular, for motor vehicle-only roads such as highways, it is good to divide them into certain areas such as by prefecture, and register a plurality of warning targets installed in the same motor vehicle-only road in the same area as the same warning target in one group.

[0198] In such a modification example, for example, when the setting item display area 43b of "orbis passing history" is touched on the function setting screen shown in Fig. 25(a), a list screen of the orbis passing history for each warning target is displayed. This list of the orbis passing history for each warning target has the same layout as, for example, the orbis passing history list screen shown in Fig. 25(b), and it is advisable that the content displayed in the part of the passing history list display section 46b be information for identifying the warning target. The information for identifying the warning target may be, for example, a road name, an address, etc., and it is particularly advisable to use a road name because it is easy to understand. The information for identifying a plurality of warning targets arranged vertically may be arranged, for example, in order from the warning target that passed most recently (see Fig. 26). When it is detected that the display section for displaying the information for identifying the warning target has been touched, the control unit 18 displays the orbis passing history list shown in Fig. 25(b), and it is advisable to configure it to display the date and time information, etc. of the passing history information belonging to the group of the touched warning target in each passing history list display section 46b.

[0199] [Modification Example of Speed Recording] In the above-described embodiments and modifications, each time a predetermined warning target is passed, speed history information associated with the passage is created, recorded, and displayed at a predetermined timing. Instead of recording all the information in this way, for example, the storage of the passage history of the own vehicle speed may be performed when the speed exceeds a predetermined speed with respect to the speed limit, and not stored when the speed is less than the predetermined speed. The predetermined speed may be, for example, 0 km / h when it is equal to or higher than the speed limit, or may be stored when the predetermined speed is 1 km / h and the speed limit is exceeded. In particular, it is preferably a speed with a predetermined margin, such as 20 km / h or 30 km / h. By doing so, the number of histories to be stored is reduced. For example, when there is an often-passed orbit, the problem of being bothered by recording each time and remaining in the history can be solved. In particular, usually, the position of the often-passed orbit is grasped and there is a tendency not to exceed the speed. When such data that does not exceed the speed remains in the history and is displayed in the list, it becomes difficult to find the desired history. However, in this embodiment, the occurrence of such a situation can be suppressed. By storing only those with a large level of speed exceeding with a predetermined margin, it is possible to effectively display dangerous driving as a history and raise awareness.

[0200] Also, warning targets for which the history is not stored may be registered at a location, and the registered ones may not be left in the history. However, it is more preferable to store only when the predetermined speed is exceeded as in the above-described modification. For example, even if one usually drives well, knows the existence of the warning target, and drives while observing the speed limit, there is still a possibility of accidentally exceeding the speed. In the above-described modification, it is preferable because the history can be stored when such a speed violation occurs.

[0201] [Modification of Display Timing] The display timing of the recorded history information may be, for example, when the power of the radar detector 1 is turned on, or when a predetermined distance before a predetermined warning target such as an orbis is reached, and it is preferably displayed when there is a passing history for that warning target. In particular, when a detailed screen of the driving history is displayed when a predetermined distance before the warning target is reached, it is good because it can efficiently and appropriately draw attention to safe driving. For example, if the content of the detailed information on the past passing history at the same displayed location shows that the speed limit has been exceeded, there is a risk that the driver may exceed the speed just like when driving on the road where the speed has been exceeded in the past, and it is possible to make the driver recognize and be alerted to the need to drive at a slightly reduced speed.

[0202] When there are multiple pieces of passing history information of the target to be displayed when the power is turned on or in front of the warning target, for example, the most recent one may be displayed, but it is more preferable to display a bad passing history with a large excessive speed because it can alert to safe driving.

[0203] In this way, the display timing may be automatically displayed when the conditions are met, but it is good to perform it based on a user operation such as screen touch as in the above-described embodiment. When displaying based on a user operation, the driver or the like, as a user, has the awareness of wanting to view and confirm the detailed information of the passing history, so they can carefully check the displayed detailed information to confirm the presence or absence of speeding and the driving tendency such as speed changes near the warning target, and it is good because it can be used as an opportunity for subsequent safe driving and the like.

[0204] [Variation 1 of Reflection in Warning] It is preferable to have a function that performs different warning contents in front of the warning target according to the content of the passing history. For example, when the control unit 18 issues a warning at a predetermined distance in front of the warning target, if there is an unfavorable passing history such as speed exceeding for the warning target in terms of safe driving, it is preferable to issue a stronger warning than the normal warning. The stronger warning may, for example, be issued at a farther distance from the normal timing of the warning, change the warning content, change the notification mode, or a combination of multiple ones is even better. When changing the warning content, for example, change the content of the voice notification performed at a predetermined distance in front to a strong statement that can prompt attention by changing it to a normal one, or perform a notification that prompts attention in addition to the normal warning. When changing the notification mode, for example, change from a notification mode that uses only one of the voice warning and the warning using the display unit to a notification mode that uses both.

[0205] The content of the passing history serving as the criterion for issuing a stronger warning may be, for example, simply when there is one exceeding the reference speed corresponding to the speed limit. It is better to have a plurality of different reference speeds, and to vary the mode of the stronger warning according to which reference speed is exceeded. The reference speed corresponding to the speed limit does not necessarily have to be equal to or higher than the speed limit, and it is preferable to set it to a predetermined speed lower than the speed limit. For example, even if the speed is below the speed limit and the vehicle is traveling at a speed close to the speed limit, if the accelerator is depressed a little harder, there is a risk of exceeding the speed limit and a risk of future accidents. If the reference speed is set to a predetermined speed lower than the speed limit, when traveling at a speed close to the speed limit, it is good because a warning or a plus-alpha warning that prompts attention when traveling next can be issued.

[0206] For example, when the reference speed is set to 90 km / h for a road with a speed limit of 100 km / h, if the driving speed in the passing history is recorded as 90 km / h or a speed close to 100 km / h, for example, a special voice warning such as "You are almost at the speed limit, please drive carefully" may be given to arouse attention to reduce the speed. The position where a vehicle speed measuring device such as an orbis is installed is a place where speed is likely to occur and there is a risk of accidents. Therefore, it is advisable to encourage not to exceed the speed when passing the same place next time and prevent accidents from occurring.

[0207] Also, when multiple reference speeds are set, as the reference speed increases, the warning given after exceeding it, for example, by warning with a more emphasized phrase, is good for promoting safe driving below the speed limit. When multiple reference speeds are set, at least one should be set below the speed limit and at least one should be set at a speed higher than the speed limit. By doing so, warnings can be given respectively for those who have not exceeded the speed but are at risk of exceeding it in the future and for drivers who are actually exceeding the speed and driving dangerously, so that appropriate attention can be drawn to safe driving for drivers with different driving trends.

[0208] The content of the passing history used as a criterion for giving a strong warning is preferably judged from the trend of the change in the vehicle speed recorded in the past passing history multiple times. For example, when passing a place with a speed limit of 110 km / h, the vehicle passed at 100 km / h last time but passed at a speed close to 110 km / h this time. For example, if the vehicle speed recorded recently has increased and is in the direction of exceeding the speed, it is advisable to give a warning to prompt attention when driving on the same road with the same warning target next time. For example, when receiving a warning in front of the warning target on a road for the first time, the vehicle will decelerate and pass at a speed sufficiently lower than the speed limit. However, as it drives several times, it gets used to it and gradually approaches the speed limit. If it continues like this, there is a risk of exceeding the speed in the future. However, as described above, if a trend emerges from the past passing history multiple times to prevent such a situation, it is advisable to give a warning for pre-warning.

[0209] For a strong alarm, it is advisable to change to voice notification, display the "detail screen for the specified passing history" and then give a normal alarm. In particular, in addition to the prominent voice notification, giving a notification that also displays the detail screen will result in a stronger alarm.

[0210] [Variation Example 2 of Reflection in Alarm] It is advisable to have a function that gives different alarms according to the past driving state. The past driving state is not limited to the passing history of the vehicle speed for a specified alarm target such as Obis as described above. For example, record the points where the specified speed is exceeded with respect to the speed limit, and when passing through those points later, it is advisable to give a specified alarm before that point.

[0211] Also, the driving state may be, for example, rough driving. Rough driving includes, for example, sudden acceleration, sudden deceleration, sharp curves, etc., and it is advisable to determine based on the output of the acceleration sensor mounted on the radar detector 1 for example. The control unit 18 records the points where such rough driving occurred, and gives an alarm before those recorded points during subsequent driving. The radar detector 1 in the above-described embodiments etc. stores the position information of the specific alarm target and has a GPS alarm function that gives an alarm before the alarm target based on GPS information, but it is advisable to have a function of adding dangerous location points based on the driving situation of the user, and also have a function of giving an alarm for those added dangerous location points.

[0212] [Variation Example of Alarm Presence / Absence Setting Function] It is advisable to have a function that actively changes the warning given in front of the warning target according to the user's driving tendency. For example, in places where the user always drives safely and below the speed limit, it is better to give a less prominent warning than usual. Less prominent warnings may include not giving any warning, but it is better to give a weaker warning. If no warning is given, there is a risk of misunderstanding it as a malfunction or accidentally exceeding the speed limit even if the user usually drives below the speed limit. Therefore, by giving some kind of weaker warning, such misunderstandings can be avoided. By doing so, even for the same type of warning target, it is possible to give a normal warning or a less prominent warning according to the user's driving tendency, and the warnings necessary for the user can be made appropriate.

[0213] For example, there are many types and numbers of warning targets for GPS warnings, and in some driving areas, warnings are frequently issued. Therefore, even if there is an important warning, there is a risk of not noticing it. If points for issuing warnings based on the driving history information of each user are added as in the above-described various modified examples, such problems will become more prominent. To reduce the number of warning occurrences, for example, the [Mode] in the setting item display area 43b of the function setting screen can be selected, and the warning can be switched on / off for each type of warning target by setting the mode. In particular, when setting it to the manual mode, the on / off setting can be individually set for each type of warning target. However, such mode settings are cumbersome, and ultimately many users use it with the initial settings. As a result, the radar detector often gives warnings, which is annoying, and there is a problem that there is a risk of getting used to the warnings and missing important warnings. However, appropriate warnings can be given according to the user's driving, and such problems can be solved.

[0214] [Linked with Drive Recorder] It is advisable to have a function that links the radar detector 1 and the drive recorder and records video data for a predetermined section when a predetermined warning target passes. The control unit 18 of the radar detector 1 transmits a trigger signal to the drive recorder when, for example, a predetermined warning target such as an orb passes. The drive recorder records images for a certain period of time before and after the passage of a warning target such as an orb upon receiving the trigger. The certain period of time may be, for example, about 20 seconds in total, 15 seconds on the front side and 5 seconds after passage. The drive recorder has a continuous recording function that continuously records and a event recording function that records videos for a predetermined period before and after the occurrence of a predetermined event. In this embodiment, it is advisable to receive the trigger from the radar detector 1 as the occurrence of an event and acquire and record images for a predetermined time before and after the passage using the same algorithm as the event recording function. It is difficult for the drive recorder to record based on the distance, such as from ○○ m in front of the warning target. By using time as the reference as in this embodiment, recording can be easily performed.

[0215] The drive recorder has a holder for continuous recording and a holder for event recording, and stores the respective video data in the respective holders. In this embodiment, a holder called "orb" is created (see Fig. 27(a) etc.). When an orb passes, files of video data before and after the passage are created and stored in the orb holder.

[0216] By managing the passing history information with the captured video, it is possible to check the driving conditions such as the weather during driving and the vehicle conditions around. For example, it can be made easier for the driver to understand the correlation between the driving conditions and the driving speed. For example, it can improve the driver's understanding and create a situation where the driver can be conscious of safe driving.

[0217] The orbis holders are preferably created for each orbis as lower-level holders. The video data created when passing through the same orbis are grouped and stored in the same lower-level holder. By opening the holder of a predetermined orbis, the user can check the video data for the same orbis and can easily compare it with the past passing history information. For example, by comparing and checking the driving data and video data for multiple passes when passing through the same orbis or the like, if there are cases where the speed limit was exceeded or driving was near the speed limit in the past, it can be found that such events occur, for example, on a specific weather such as a sunny day, and when driving on other weather, the vehicle is driving with a margin for the speed limit. Then, it is good to be able to be aware of driving safely especially when driving on a sunny day.

[0218] The history information recorded along with the passage of a predetermined warning target is recorded on a memory card, for example, in the same way as other always-recorded and event-recorded information. When viewing the history information, for example, by taking out the memory card and setting it in a personal computer or the like and reading a predetermined file, it is good to play it on the personal computer. In such a case, if it is divided into holders for each warning target as described above, it is good that the user can easily find the history information when passing through the desired warning target.

[0219] It is preferable to have a function of displaying the reproduced video data on, for example, the display unit of the radar detector 1. With such a function, it can be checked on the spot in the vehicle without setting it on a personal computer or the like as described above. For the reproduction of the video data, for example, a reproduction button area of the video data is set within the detailed information display screen shown in FIGS. 25(c) and (d), and when it is detected that the reproduction button area has been touched, the control unit 18 may, for example, acquire the video data of the passing history displayed on the detailed information display screen from the drive recorder and reproduce it. As the reproduction button area, it is preferable to separately set a special button area such as an SD output button. However, instead of separately setting such a special button area, for example, the reproduction button area is assigned to a processing area that displays other information such as the real image 47f, and when, for example, a portion of the real image 47f is touched, the related video data is acquired and reproduced, which is particularly preferable. By using it in this way, there is no need to separately secure an area for the reproduction button area, and it is preferable because an area for displaying information such as the vehicle speed can be widely secured. In particular, as exemplified above, when the display area of the real image 47f is also used as the reproduction button area, it is preferable because it is easy to intuitively understand and recall the reproduction of the video.

[0220] As described above, instead of or in addition to the function of playing back video data by linking from the detailed information display screen of the passing history of each vehicle speed, it is preferable to provide a function of directly reading and playing back video data separately from the passing history of the vehicle speed. For such a function, for example, when the function button 42b in the setting menu screen, which is the top screen of the second menu screen shown in FIG. 5(c), is touched by the control unit 18, the first page of the function setting screen shown on the left side of FIG. 11(b) is displayed, and the page of the function setting screen displayed with the touch of the cursor button 43c may be of a layout as shown in FIG. 27(b), for example. In the function setting screen shown in FIG. 27(b), a button area for playing back video data named "Orbis passing history (video)" is set in the fourth setting item display area 43b. When the control unit 18 detects that the fourth setting item display area 43b has been touched, it displays, for example, a list screen of Orbis passing history for video data as shown in FIG. 27(c). In this example, an example of the case where it is grouped and recorded for each road name is shown. When it is not grouped, the control unit 18 may display a passing history list similar to that in FIG. 5(b), for example.

[0221] [Function of recording video data on the radar detector side] In the above-described embodiments and modified examples, when the video data of the passing history is displayed and played back on the display unit 4 of the radar detector 1, the control unit 18 acquires and plays back the video data recorded in the drive recorder. However, for example, it is preferable to previously store the video data in the storage means of the radar detector 1 and have the control unit 18 play back the video data stored in the radar detector 1.

[0222] For example, the radar detector 1 and the drive recorder are separate and of a cable connection type, and each is equipped with a memory card such as an SD card. When the control unit 18 of the radar detector 1 reaches a position of a predetermined warning target, it requests video data such as videos and images from the drive recorder. When the drive recorder receives such a request, it transmits, for example, video data for a predetermined time before and after the time of reception. The control unit 18 may record the transmitted video data on the memory card 11 of the radar detector 1. By doing so, the drive recorder only needs to record general continuous recording and event recording on its own SD card, and does not need to record video data of the passing history of the warning target. For example, the continuous recording of the drive recorder may be overwritten and deleted, and there may be cases where the storage capacity for event recording becomes full and additional storage is not possible. However, by saving on the memory card 11 of the radar detector 1 each time it passes, even if a situation occurs where the data is overwritten and deleted on the drive recorder side or cannot be recorded due to storage capacity overflow, it is possible to record the video data of the passing history of the warning target.

[0223] The control unit 18 may record the acquired video data directly on the memory card 11. However, for example, it is better to create and record a plurality of files in time series of photo images like snapshots from the video data. By doing so, not much capacity is required, and it is possible to record video data of a large number of passing histories.

[0224] The playback timing of the video data may be, for example, when passing that location next time. When the current position of the vehicle reaches a predetermined distance in front of a warning target, for example, the control unit 18 accesses a holder that records the video data of the passing history of that warning target. If there is previous recorded video data, it reads it out and displays the video on the display unit 4 of the radar detector 1. When displaying this, it is advisable to display a message such as "This is the scenery when driving last time." in voice or as a telop on the display unit 4. By doing so, since the video data when passing the warning target last time is played back, the driver or the like can look at the video, recall the previous driving / running situation, and be able to arouse attention for the current driving. When displaying past video data in front of a warning target, since the vehicle is approaching the warning target moment by moment during driving, the time margin for reading and playing back is short. However, by using the video data recorded in the radar detector 1, the desired video data can be instantaneously read out and played back. If one tries to use the video data recorded in the drive recorder, it takes time to acquire the video data from the drive recorder and it may not be possible to play it back at the desired point, or there is a risk that the past video data is overwritten on the drive recorder side and cannot be acquired. However, when playing back the video data recorded in the radar detector 1, there is no such problem.

[0225] For the passing history information of the video data recorded in the drive recorder, for example, the radar detector 1 may be made to store the information on the speed limits of each road, and trigger recording of the video before and after when exceeding a predetermined speed with respect to the speed limit. However, it is better to use the passing of a predetermined warning target such as an obis as a trigger as in the above-described modified example. When recording video with exceeding a predetermined speed as a trigger, it is difficult for the user to recognize where that location is even when playing back the video, and the passing history information that cannot contribute effectively to subsequent safe driving increases, and in particular, it is not preferable that it becomes difficult to search for the passing history information of an obis or the like that requires special attention for safety. Therefore, it is advisable to narrow down the recording of video data to a predetermined warning target.

[0226] The recording of video data may be performed, for example, based on the conditions and trends inside the vehicle when an abnormal, unusual, or emergency event that should be recorded occurs outside the vehicle. The conditions and trends inside the vehicle may be, for example, audio information such as changes in the sound inside and outside the vehicle. The occurrence of an abnormal, unusual, or emergency event that should be recorded outside the vehicle may be, for example, the sudden appearance of wild boars, deer, monkeys, etc. in the wild such as in the mountains, or when the vehicle is being tailgated. The sudden appearance of an animal may, for example, lead to a situation where the animal then collides with the vehicle and the vehicle is damaged, or in the case of tailgating, may lead to an accident or a situation where the passengers in the tailgating vehicle get out and approach. When the impact on the vehicle due to an accident, collision, etc. is large, the acceleration sensor detects the collision, and the drive recorder can record event data and record the video data before and after the collision based on this detection. However, in the case of a weak impact that cannot be detected, the acceleration sensor cannot detect the collision, and only continuous recording is possible without event recording. Then, if the continuously recorded video data is overwritten, there is a problem that the video of the collision cannot be saved.

[0227] An example of the audio information that is an example of the conditions and trends inside the vehicle may be, for example, the cheers or noises of children, words indicating the appearance of animals such as "Wow, it's a ○○" or "A ○○ has appeared", or voices of agreement such as "Really". The control unit 18 may record the video data, for example, triggered by the frequency or level of the sound corresponding to cheers or noises, or the appearance of a predetermined keyword based on voice recognition.

[0228] For example, the determination process based on audio information may be performed on the drive recorder side for recording the video of the situation at the time of an accident. However, when displaying the historical data of past passages on the display unit 4 of the radar detector 1, for example, a microphone may be built into the radar detector 1, and the control unit 18 performs the determination process based on the output of the microphone. When the conditions are met, the video data of the intervals before and after that is acquired from the drive recorder and recorded on its own memory card 11.

[0229] For example, when tailgating occurs, in addition to the in-vehicle voice, it is advisable to record video data based on the voice of the other party such as "Hey". For example, when a drive recorder has a function of recording an event by operating a predetermined switch, when the other party who was tailgating gets out of the vehicle and approaches, operating the predetermined switch can record the event, but the pressing process is complicated and there is a risk that it cannot be operated urgently. Even when the vehicle is equipped with a function of automatically recording an event based on the output of an acceleration sensor when a certain impact or more is applied to the vehicle, such as hitting or shaking the vehicle after the other party approaches, there is a problem that the event is not automatically recorded if the impact is small. As in this embodiment, it is preferable that event recording can be automatically performed based on changes in sound or the like because video data can be surely recorded.

[0230] When recording video data using the changes in the sounds inside and outside the vehicle described above as a trigger, for example, a microphone may be built into the radar detector 1 to record the sound, and when passing through the same location later, the control unit 18 may output the sound at a predetermined point in front of it. By doing so, the situation when passing by last time can be known from the sound, so it is easier to remember the situation. For example, since there is a possibility that the animal is at the same location where the animal appeared before, it is advisable to have a function of giving a notification such as sound reproduction in front of that location. With such a function, the driver can drive while paying attention to the surroundings. In this case, when the video data is reproduced together, the user who sees it can more easily remember the situation, which is preferable. However, it is better to output only the sound without reproducing the video. Even with only the audio data, the situation at that time can be sufficiently remembered, and by not reproducing the video data, other useful information can be displayed on the display unit 4.

[0231] It is advisable to have a function of recording the animal discovery point as an alarm target for the user like a my point and giving an approach alarm to the alarm target for the user. The approach alarm may be, for example, a moving image or a still image using pre-prepared CG or the like displayed in the alarm image display window W3, but it is good to be configured to reproduce the actually recorded sound to give a sense of presence.

[0232] [Function for changing the intensity of the alarm] The control unit 18 preferably has a function of changing the intensity of the alarm based on user settings. For example, it can be changed. In the mode setting function in the above-described embodiment, for each item of the alarm, a binary choice of "do / do not" was made. In this embodiment, for example, a plurality of alarm levels are prepared, and when an alarm is issued, the alarm level can be selected. The strength of the alarm level, for example, in the case of voice notification, for example, change the voice level (for example, increase the volume for a stronger alarm), change the content of the voice itself, or in the case of notification using the display unit, for example, change the displayed content or the notification mode. Furthermore, for example, it is more preferable to increase the location or frequency of issuing the alarm as the alarm level is stronger.

[0233] The alarm level classification can be, for example, two levels such as a normal alarm and a stronger level alarm or a weaker level alarm, three levels such as weak, normal, and strong, or even more. However, if the number of levels is increased too much, the setting becomes complicated and the effect caused by the level classification is not so great, so it is better to have two levels. For example, if it is set to two levels such as a normal level and a stronger level, even a user who does not notice the normal level alarm can be made to issue a stronger level alarm by mode setting, so that the user can notice the alarm and promote safe driving. For example, for a user who easily forgets to wear the seat belt, if an alarm is frequently issued, for example, before the entrance of the highway, it is possible to prompt the user to wear the seat belt.

[0234] [Modification example of the standby screen] FIG. 28(a) shows an example of a standby screen. The illustrated standby screen has a layout in which three mini meters 37 are arranged vertically on each of the left half side and the right half side of the main display area R1. Each mini meter 37 includes an item name display section 37a at the upper left, a character information display section 37b at the lower left, and a circular meter-like display section 37c on the right side. The control unit 18 displays the item of information to be displayed on the mini meter in the item name display section 37a. In the illustrated example, from the top in order on the left side, time, speed (0 - 180 Km / h), and number of satellite receptions are displayed, and from the top in order on the right side, calendar, compass, and air pressure are displayed. The control unit 18 displays the information related to each item using one or both of the character information display section 37b and the meter-like display section 37c. For example, for the mini meter 37 regarding "time" in the upper left, the current time is digitally displayed in the character information display section 37b, and the current time is displayed as a schematic diagram of an analog clock in the meter-like display section 37c. Thus, as types of displaying the same content in different modes by the character information display section 37b and the meter-like display section 37c, in addition to this "time", there are "speed", "compass", "air pressure", etc. For the mini meter 37 regarding "calendar" in the upper right, the day of the week ("Tuesday" in the example of the figure) is displayed in the character information display section 37b, and "month" is displayed in the upper part and "day" is displayed in the lower part in the meter-like display section 37c. Thus, there is also a type of displaying one piece of information by combining the character information display section 37b and the meter-like display section 37c. Also, for the mini meter 37 regarding "number of satellite receptions" in the lower left, the character information display section 37b is not displayed, and the number of currently received satellites is displayed in the meter-like display section 37c. Thus, there is also a type of displaying information using only one of the character information display section 37b and the meter-like display section 37c. The information displayed on each mini meter 37 is preferably made changeable by setting.

[0235] As an item to be displayed on this mini-meter 37, it is preferable to provide information regarding the speed limit. As an example of the display of this information regarding the speed limit, for example, as shown in FIG. 28(b), for example, the control unit 18 may display "Speed Limit" on the item name display unit 37a, display the speed limit in characters such as "60 km / h" on the character information display unit 37b, and display a mark imitating the traffic sign of the speed limit on the meter-style display unit 37c. By doing so, for example, at the speed limit switching point, in a device equipped with a function of notifying the speed limit by voice or the like, even if one misses hearing it, by looking at the standby screen in this form, it is possible to confirm the speed limit of the road currently being traveled. Also, for example, as shown in FIGS. 18 and 19, in a state where the map screen is displayed when approaching the warning target, the speed limit is displayed, but in this form, it is sufficient to know the speed limit in the state of the standby screen before transitioning to the map screen displayed when approaching the warning target. Even in a section where no traffic signs are installed on the actual road, by looking at the standby screen that displays the speed limit, it is possible to confirm the speed limit of the current road, so it is possible to suppress the risk of exceeding the speed limit as much as possible.

[0236] As an item to be displayed on this mini-meter 37, it is preferable to provide information for specifying the warning target. For example, when approaching the warning target, the control unit 18 may display information regarding the warning target on the mini-meter 37 at a predetermined position without switching to the warning screen using the above-described map screen. By doing so, it is possible to give a proximity warning of the warning target while notifying the desired information using the standby screen. As information for specifying the warning target, for example, the control unit 18 may display a target icon drawn at a location corresponding to the installation position of the warning target on the map on the meter-style display unit 37c, and display the remaining distance to the warning target on the character information display unit 37b. Further, the control unit 18 preferably has a function of changing the color of the frame and / or the background color of the mini-meter 37 according to the color (red, yellow, blue, green) of the warning target. By changing the color of the frame or the background color, it is possible to easily understand the approximate type of the warning target, and it is more preferable to change the background color as well, as the degree of understanding increases.

[0237] The approach warning for the warning target using the standby screen is not limited to using the detailed mini meter 37 described above. For example, it is advisable to use predetermined elements constituting the standby screen such as the small meters 32b and 32c shown in FIG. 3 and the like, or the large meter 38a shown in FIG. 29(a). For example, the standby screen shown in FIG. 29(a) has a layout in which the large meter 38a is arranged on the right side of the main display area R1, and two small meters 38b and 38c are arranged vertically on the left side. In the illustrated example, the control unit 18 displays a clock (analog) on the upper small meter 38b, a compass on the lower small meter 32c, and satellite information on the large meter 38a. In this example, a picture schematically showing the position of the satellite that has received the radio wave is displayed on the large meter 38a.

[0238] For the warning using this large meter 38a, for example, when a warning target exists within a predetermined distance or less from the vehicle position, for example, the center of the circle of the large meter 38a is set as the vehicle position, for example, the front in the traveling direction is set as the upper side of the circle, and a mark identifying the warning target is displayed at the corresponding position of the warning target within the circle. This mark may be, for example, the same as the target icon. By doing so, the notification of the warning target using the large meter 38a becomes a mode in which the map information on the map screen is eliminated and the vehicle icon and the target icon are drawn in a predetermined positional relationship. By doing so, it is good that the approximate position of the warning target can be recognized without displaying the map screen.

[0239] As an example of the warning using the large meter 38a, for example, as shown in FIGS. 29(b) and (c), it is advisable to adopt a layout in which the own vehicle icon 39a is displayed at the center of the circle, and a mark 39b identifying the warning target existing around it is displayed at a position where the relative positional relationship matches. Also, as shown in the figure, if a plurality of concentric circles 39c of a perfect circle or concentric circles 39' of an ellipse centered on the own vehicle icon 39a are displayed in multiple lines and the diameter of each circle is set to a predetermined distance (for example, 500 m, etc.), it is good that the approximate distance to each warning target can also be known. When drawing concentric circles 39c of a perfect circle as in FIG. 29(b), it becomes a 2D mode of a plan view, and when drawing concentric circles 39c' of an ellipse as in FIG. 29(c), it becomes a 3D mode of a bird's-eye view.

[0240] In the warning including the relative positional relationship of the warning target using the large meter 38a, compared with the warning using the map screen that uses the entire main display area, since the display area is smaller, the target icon displayed at the position of the warning target also becomes smaller, resulting in a new problem that it becomes difficult to see. In order to solve such a problem, for example, it is good to display the color of the outer frame of the large meter 38a and the background color inside the circle of the large meter 38a with the color of the warning target (red, yellow, blue, green). By doing so, the approximate type of the warning target can be known from such colors.

[0241] In the standby screen for a hybrid vehicle shown in FIG. 3(d), two mini meters 34a and 34b are displayed in the upper region, and hybrid information is displayed in the lower region below them. The information displayed on these mini meters 34a and 34b is preferably switchable by setting, and it is more preferable to have a function of switching the information displayed in the hybrid information by setting.

[0242] As items to be displayed on a predetermined meter in the standby screen using the above-mentioned large meter, small meter, and mini meter, it is preferable to include information related to driving checks. The information related to driving checks may include, for example, the driving state of the vehicle, the state of dangerous driving such as sudden steering / sudden braking, and eco-drive information regarding whether eco-driving for fuel efficiency improvement is being performed. For example, a predetermined mini meter 37 is used to display information related to dangerous driving. The control unit 18, for example, from the output of the acceleration sensor, when the acceleration is less than or equal to the first reference value, sets the background color of the mini meter 37 to green, when it is greater than the first reference value and less than or equal to the second reference value, sets the background color of the mini meter 37 to yellow, and when it exceeds the second reference value, sets the background color of the mini meter 37 to red, and it is preferable to display a mark for identifying sudden braking or sudden steering within the meter. Also, the control unit preferably has a function of displaying eco-drive information on the mini meter and the small meter. For example, the eco-drive information is obtained by scoring whether eco-driving is being performed based on information such as sudden acceleration, sudden deceleration, idling time, and whether driving at the economic speed is possible. The control unit 18 preferably displays the score obtained in this way on a predetermined mini meter, and / or obtains the score at predetermined time intervals and displays the change / history of the constant on the small meter. Also, the control unit 18 preferably has a function of recording the scoring result of the eco-drive information in a predetermined driving unit such as each time of driving, comparing the scoring result based on the current driving with the scoring results based on past drives such as the previous one, and notifying the increase or decrease in the score. By doing so, it is good because it can be known whether the current driving has achieved better eco-driving. The function of notifying the increase or decrease in the score is, for example, easy to borrow a story because the recognition degree is high when it is matched with the color combination of the signal. The color combination of the signal is preferably, for example, red when it gets worse, yellow when there is no change, and green when it gets better.

[0243] The standby screen is provided with various meter-style display sections such as, for example, a large meter, a small meter, and a mini meter. For example, when changing the color with the "base color" of the setting items belonging to the system, for example, the entire main display area may be changed, but it is better to change within the range of the circular area of the meter and not change the outside (see Fig. 30). For example, the background color of the main display area is unified into a thick color such as black, and by changing the background color within the range of the circular area of the meter, the changed color can be made prominent.

[0244] [Function related to head-up display, etc.] It is advisable to have a function of connecting a head-up display to the radar detector 1 and displaying information such as the current driving speed and hourly speed, and various warnings on the front windshield of the vehicle by the head-up display. By doing so, it is smart, and the driver can recognize the driving speed, warning content, etc. without significantly changing the line of sight while looking ahead during driving.

[0245] When implementing a drive recorder while cooperating with the head-up display, it is advisable to set it so that the head-up display is displayed within the shooting area of the drive recorder. By doing so, for example, the driving speed and warning content can be reflected and recorded in the video data captured by the drive recorder. For example, when the recorded video data is played back later, the driving speed is displayed together with the scenery during driving, so that users such as drivers can easily confirm at what driving speed they were driving at which location. Also, the user can confirm from the outside scenery when the warning is issued at which location they were driving during driving. Combined with the superimposition of the outside scenery, it becomes easier to remember the location where the warning is issued, which can contribute to safe driving when driving on the same road later. It is more preferable to have a function of adjusting the reflectivity of the head-up display on the front windshield. By adjusting the reflectivity, the driving speed, warnings, etc. can be reflected more beautifully in the video data captured by the drive recorder.

[0246] Normally, the shooting area of the drive recorder is adjusted so that the front view of the vehicle or the like is reflected, and the display unit 4 of the radar detector 1 arranged on the dashboard of the vehicle or the like is outside the shooting area. However, in this embodiment, the display of the head-up display output from the radar detector is in a positional relationship that can be reflected by the drive recorder. By having such a feature, for example, the above-described effects can be achieved, and also, for example, even a drive recorder not equipped with a GPS function can record the traveling speed.

[0247] [Data update function via Bluetooth (registered trademark)] For example, when updating data such as data about an object to be alerted for GPS alerts, in the above-described embodiment, an example of using the memory card 11 was described. However, the present invention is not limited to this, and it is preferable to use a wireless communication function. For example, the radar detector 1 of the above-described embodiment has a wireless LAN connection function using WiFi connection. For example, when the control unit 18 detects that the button area of "manual download" or "automatic download" has been touched while displaying the WLAN setting screen (2 / 3) shown in the center of FIG. 11(d), it executes a predetermined process for downloading update data and performs data update. In this case, for example, it is necessary to connect the radar detector 1 and the smartphone in advance via wireless LAN. In order to make this connection, for example, it is necessary to turn on the desiring of the smartphone, which is troublesome. To solve such a problem, it is preferable to provide a function of performing wireless communication between, for example, the radar detector 1 and a mobile terminal such as a smartphone using Bluetooth and performing data update. For example, when an app for data update is installed on the smartphone and the app is launched, a connection via Bluetooth is made between the smartphone and the radar detector 1, and new update data is wirelessly transmitted from the smartphone side to the radar detector 1. The radar detector 1 performs data update based on the acquired update data. It is preferable to provide a function that an app for performing various settings of the radar detector 1 can be installed on a mobile terminal such as a smartphone and the settings of the radar detector 1 can be made by executing the app. By doing so, a user such as a driver can make the settings of the radar detector 1 by operating a familiar smartphone or the like, so that the settings can be easily made. Since the operation can also be performed at hand, it can be done more easily. By simplifying the setting operation, the awareness of switching the settings becomes stronger, and the radar detector 1 with settings more suitable for oneself can be configured, and the necessary information can be notified in an appropriate notification mode without excess or deficiency.

[0248] [Function to turn off the screen except during warnings] The control unit 18 preferably has a function of making the display unit 4 in a non-glare state during normal times when no warning is issued. For example, in the above-described embodiments, etc., during normal times when no warning is issued, for example, a standby screen or the like is displayed to issue some information. In this configuration, the display unit 4 emits light constantly, and there is a problem that it is dazzling usually. If, like in this embodiment, it has a function of making the display unit 4 in a non-glare state during normal times when no warning is issued, then there will be no glare during that normal time, and for example, a function suitable for a user who usually finds it dazzling and thus does not need screen display can be provided.

[0249] The function of making the display unit 4 in a non-glare state is preferably, for example, to draw the entire screen of the display unit 4 in a color such as black or other dark colors or non-glare colors. In particular, it is more preferable to turn off the power of the liquid crystal display constituting the display unit 4. To solve the same problem, the display unit 4 may also be provided with a function of making it non-displayed without screen display.

[0250] [Surrounding camera display function] It is equipped with a front camera that captures the front of the vehicle and a side view camera that captures the left and right of the vehicle, and connects both of these cameras to the radar detector 1. For the front camera, it is preferably to use a wide-angle camera attached around the front bumper of the vehicle, for example. For the side view camera, it is preferably to use a wide-angle camera attached under the side mirror of the vehicle, for example. When the control unit 18 of the radar detector 1 recognizes that it is about to merge into a T-junction intersection or the like based on the map information or the like stored in the radar detector 1, for example, it has a function of displaying the video captured by the front camera on the display means such as the display unit 4 or the above-described head-up display, and automatically displaying the video captured by the side view camera when receiving a turn signal from the OBD information, for example. By doing so, it is good because the driver does not need to manually switch the camera video displayed on the display unit.

[0251] The switching of the cameras to be displayed is not limited to being based on the map information described above. For example, it may be performed based on the warning target. For example, a front camera as described above and a back camera capable of photographing the rear of the vehicle are provided, and both cameras are connected to the radar detector 1. For example, the control unit 18 may display the video captured by the front camera before the passage of a warning target such as an obis, and display the video captured by the back camera after the passage of the warning target such as an obis. Thus, the switching of the camera for displaying the video is more preferably based on the map information described above than based on the warning target because useful information can be obtained.

[0252] When photographing the front with the front camera and the rear with the back camera based on the warning target, in particular, the control unit 18 may record the captured videos on, for example, the memory card 11 or the like. Recording is preferable because the situation around the vehicle before and after passage can be confirmed later.

[0253] [Warning function based on captured image data] The radar detector is preferably provided with photographing means for photographing the front and a function of issuing a warning based on the image data photographed by the photographing means. The photographing means may be built in integrally with the main body of the radar detector 1 or may be a separate photographing means. It is preferable to use a separate one because it is easier to install the photographing means at a place where it is easy to capture the target video.

[0254] The warning based on the image data is preferably performed, for example, when a predetermined detection target exists in the captured image data. The detection target may be, for example, a sign for promoting safe driving or a sign for notifying the presence of a warning target ahead on the road being traveled. In particular, it is good to set as the detection target a "regulation warning sign", which is one of the signs for notifying the presence of a warning target ahead on the road being traveled. The control unit 18 is preferably provided with a function of detecting and warning a "regulation warning sign" in the image data obtained by photographing with the photographing means, for example, by real-time image processing.

[0255] The "enforcement warning sign" is also referred to as a "prior warning sign" or "advance notice sign". For example, as shown in Fig. 31, in front of the location where speed enforcement is being carried out, an enforcement warning sign 73 is installed at a predetermined position such as the side of the road. In the illustrated example, the enforcement warning sign 73 is a vertically long board with a blue background color and white characters handwritten with words such as "Speed Violation Monitoring in Progress". Also, although specific figures are omitted, a warning sign such as "Route with Automatic Speed Enforcement Device Installed" is installed at a predetermined distance in front of the installation position of the route where the automatic speed enforcement device is fixedly installed. The words displayed on these enforcement warning signs are not limited to the above, and there are several types such as "Section with Automatic Speed Enforcement Device Installed", "Automatic Speed Monitoring", "Route with Automatic Speed Enforcement", etc., but they are not limited to specific words. Therefore, the control unit 18 performs, for example, a predetermined image recognition process on the image data obtained by the imaging means, extracts, for example, the part of the sign, performs a character recognition process on the characters described there, and issues an alarm based on the image data in the case of pre-registered characters. Since the character recognition process performed here only needs to be performed on specific characters, real-time determination can be made even if the performance of the CPU of the control unit 185 is not very high.

[0256] In this way, for example, if it has a function of detecting and notifying an enforcement warning sign, for example, although an alarm based on GPS cannot be issued because the position information has not been registered, an alarm can also be issued for a speed enforcement device such as Obis. A speed enforcement device such as Obis for which the position information has not been registered is a newly installed one, and it is a good location to promote safe driving based on the recent traffic situation, etc. Therefore, by issuing an alarm for such a location, it can contribute to safe driving.

[0257] In particular, for the sign installed in front of a small Obis or a mobile Obis, since only a simple standing sign is installed, there is a problem that it is easy for drivers and the like to overlook it. With the function of this embodiment, even for such a simple standing sign that is easy to overlook, it can be detected and notified, so that the driver can surely recognize its existence.

[0258] [Warning Function Using Road Elevation Data] The radar detector may record the elevation data of the road. The control unit 18 preferably has a function of acquiring altitude information together with the longitude and latitude position information of the current location from the GPS information and identifying the road currently being traveled using the acquired altitude information. By doing so, stable road identification becomes possible. The control unit 18 preferably issues an alarm regarding the road currently being traveled and does not issue a normal alarm for an alarm target not related to the road currently being traveled. Not issuing a normal alarm includes, for example, the case of not issuing an alarm and the case of issuing a mild or weak alarm. By doing so, the alarm regarding the road being traveled can be focused on, preventing the occurrence of unnecessary alarms and making it possible to issue a mild and non - concerning notification. For example, when an expressway and a general road exist side by side, it may not be possible to identify whether one is traveling on the expressway or the general road based only on the longitude and latitude position information. However, with the function of this embodiment, stable road identification becomes possible. Therefore, for example, when it is recognized that one is traveling on an expressway, it is good not to issue a normal alarm for speed enforcement devices such as orbis provided on the general road and other alarm targets. Conversely, when it is recognized that one is traveling on a general road, it is good not to issue a normal alarm for alarm targets related to the expressway.

[0259] [AR Alarm] The drive recorder and the radar detector are coordinated. It is preferable that the radar detector has a function of analyzing GPS information and the live image captured by the drive recorder to issue an AR warning. When an AR warning is issued, the desired warning and notification are made in the actually captured video, so that the reality is enhanced and attention can be more effectively drawn. The AR warning may be, for example, in a manner that makes the presence of the warning target conspicuous in the video captured and displayed on the display unit or the like, and is superimposed on the image by AR for notification. As a conspicuous manner, for example, it is preferable to create an indication element such as a frame or an arrow by CG or the like and display it in association with the warning target in the image. The associated display is preferably arranged in such a way that the user can easily understand that the indication element points to the warning target. For example, it may be superimposed on the warning target or arranged near the warning target. When the indication element is a frame, it is preferably arranged to surround the whole or a part of the warning target. When the indication element is an arrow, it is preferably arranged such that the warning target exists at the tip of the arrow.

[0260] As an example, for example, when analyzing the captured image and recognizing a police officer at an intersection, it is preferable to issue an AR warning so that the presence of the police officer can be known. Also, when equipped with a camera for shooting the rear of the vehicle, it is preferable to recognize a white bike, a police car, an undercover police car, etc. based on the image data of the rear captured and issue an AR warning. Also, it is preferable to create a character representing the warning target by CG or the like and display the character superimposed on the display position of the warning target to issue an AR warning.

[0261] It is advisable to implement the function of a drive recorder in the radar detector described in the above embodiments, modifications, etc. The radar detector 1 is preferably installed on the dashboard in order to improve the visibility from the driver to the display unit 4. A conventional general drive recorder has a camera that captures the front of the vehicle with the main body attached to a predetermined position of the vehicle. The shooting direction of the camera faces forward in the horizontal direction, and the viewing angle of the camera is adjusted to be equal-angled on the upper side with respect to the horizontal. To facilitate such adjustment, for example, when the case is rectangular, the direction of the camera is made parallel to the bottom surface of the case. In this way, when the case stands upright so that the bottom surface of the case is parallel to the floor surface of the vehicle, etc., the camera also faces forward in the horizontal direction.

[0262] In the radar detector 1 equipped with a drive recorder function, when the direction of the camera is the same as that of the above-mentioned conventional general one and the radar detector 1 is installed on the dashboard of the vehicle 80, as shown in Fig. 32(a), the viewing angle 81 of the camera mounted on the radar detector 1 has the bonnet 82 of the vehicle 80, and the bonnet 82 is reflected in the camera, resulting in the problem that most of the lower half region of the viewing angle 81 of the camera becomes a blind spot.

[0263] Therefore, in this embodiment, for example, as shown in Fig. 32(b), when mounting the camera 8 on the rear surface 2a of the case 2 facing the front of the vehicle in the mounted state of the case 2 in a rectangular and upright posture, the range of the viewing angle of the camera 8 is set at a certain angle and directed obliquely upward. In this way, for example, when the case 2 is mounted on the dashboard of the vehicle 80 so as to stand upright in a vertical state, the camera 8 assumes a posture of facing obliquely upward, and for example, as shown in Fig. 32(c), the viewing angle 81 also covers the range obliquely above the front of the vehicle 80. And when the direction of the camera 8 is set so that the lower boundary of the viewing angle 81 is above the bonnet 82 in the state where the radar detector 1 is installed, it is preferable because there is no blind spot in the camera 8.

[0264] Fig. 32(d) shows a modified example of the radar detector 1 equipped with a drive recorder function. In this modified example, the outer shape of the case 2' has a substantially trapezoidal longitudinal section, and the rear surface 2'a is an inclined surface. The center of the imaging angle 81 of the camera is made orthogonal to the inclined surface. As a result, the direction of the camera 8 and the rear surface 2'a are aligned, so that the camera 8 can be mounted on the case 2 without being conspicuous.

[0265] For example, when a radar detector integrated with a drive recorder is mounted on the dashboard of a vehicle, if the camera is installed to face forward in the horizontal direction, as described above with reference to Fig. 32(a) for example, there is a problem that the bonnet of the host vehicle is reflected in the video data captured by the camera. As in the above-described form, when the imaging angle of the camera 8 is directed obliquely upward, dead angles are eliminated or reduced, so that this problem can be solved. On the other hand, the resolution of the video data captured by the camera 8 decreases from the center to the periphery. Therefore, when the camera 8 is directed obliquely upward as in the above-described form, a new problem occurs in that the vehicle ahead or the like is located near the periphery of the imaging angle range of the camera 8 with low resolution. Considering video recording at the time of an accident or the like in the drive recorder, the installation of the drive recorder itself is more advantageous, for example, at the upper part of the windshield.

[0266] Implement a wireless communication function such as WiFi in a radar detector integrated with a drive recorder, and attach the radar detector 1 at a predetermined position, for example, above the upper part of the windshield of a vehicle. Prepare a terminal equipped with a wireless communication function such as WiFi and a display unit like a smartphone, maintain a state of being wirelessly connected to the radar detector, and the radar detector has a function of transmitting a warning screen and a captured video to the terminal, and the terminal has a function of displaying the received warning screen and captured video on the display unit of the terminal. By doing so, for example, the scenery in front such as the vehicle ahead can be captured in the area near the center of a high-resolution camera. By installing a terminal such as a smartphone on the dashboard or placing it in the hands of a user such as a driver, the user can check the warning screen and the captured video on the terminal near him / her. Also, by implementing such a function, for example, even for a model of a radar detector integrated with a drive recorder that has no screen or a model with a small screen of about 1.5 inches, the warning screen, the captured video data, etc. can be visually recognized on a large screen in a clear state.

[0267] [Radar detector with a two-screen drive recorder function] The radar detector with a drive recorder function has, for example, a drive recorder function. The radar detector 1 of this embodiment includes, for example, a horizontally long and wide case 2 as shown in FIG. 33, and is installed on the dashboard of a vehicle or the like via a bracket 3. It is preferable that this radar detector 1 can also be installed on the back side of the sun visor, the back side of the rearview mirror, etc. according to the change of the bracket 3. The display unit 4 provided on the front surface of the case 2 of this radar detector 1 includes a first display unit 4a and a second display unit 4b arranged in parallel in the horizontal direction.

[0268] The radar detector 1 with a drive recorder function uses a Video SoC equipped with a CMOSSensorI / F that can perform image processing for both the function as a radar detector and the function as a drive recorder, and it is preferable to perform the processing as a radar detector and the processing as a drive recorder in one chip.

[0269] The radar detector 1 preferably includes two screens, a first display unit 4a and a second display unit 4b, and a setting function for setting the types and contents to be displayed on the two screens. For example, it is preferable to set the left first display unit 4a as the display unit for the drive radar and the right second display unit 4b as the display unit for the radar detector. When the above setting function enables settings such as swapping the display positions or outputting different images / videos, it is more preferable to use the first display unit 4a for the drive recorder and the second display unit 4b for the radar detector. When equipped with the function of a drive recorder, usually, the camera is provided near the center in the vehicle width direction. Therefore, the radar detector 1 equipped with the drive recorder function in this embodiment is preferably installed, for example, near the center in the vehicle width direction. In this way, in the case of a right-hand drive vehicle such as a Japanese vehicle, for example, the second display unit 4b is arranged on the side closer to the driver during driving, making it easier for the driver to confirm the beneficial video notification by the radar detector during vehicle travel. Also, since the first display unit 4a is arranged on the side closer to the passenger seat, for example, when there is a passenger in the passenger seat, it makes it easier for that passenger to view the video captured by the camera with the drive recorder function.

[0270] Although illustration is omitted, the radar detector 1 including the first display unit 4a and the second display unit 4b is provided with a video input terminal for connecting to another external camera, and displays the video from the other external camera on one of the first display unit 4a and the second display unit 4b, and on the other display unit, it is preferable to have a function of displaying a display screen for a drive recorder or a radar detector. For example, when a display screen for a radar detector is displayed on the other display unit, it is good for the driver to receive useful video notifications by the radar detector during the running of the vehicle and to view the video captured by the external camera. In particular, the external camera is preferably one that captures an area other than the front of the vehicle. When it is configured to capture an area other than the front of the vehicle, it is possible to display on the display unit a view outside the field of view of the driver facing forward during forward movement. Also, the external camera is preferably set to capture in a direction different from that of the camera for a drive recorder in particular. In the case where it is set to capture in such different directions, in particular, it is good to display the video captured by the external camera on one display unit and the video captured by the camera for a drive recorder on the other display unit. By doing so, videos captured in different directions can be simultaneously displayed on two screens.

[0271] In the system configuration with the above-described external camera connected, the control unit 18 of the radar detector 1 preferably has a setting function for setting the types and contents to be displayed on the two screens of the first display unit 4a and the second display unit 4b.

[0272] When the display in normal times without an alarm is configured to output and display video data captured by a camera for a drive recorder, an external camera, etc. on both the first display unit 4a and the second display unit 4b, when an event of notification / alarm as a proximity alarm for an alarm target or other radar detector occurs, at least one of the first display unit 4a and the second display unit 4b may display an alarm / notification screen based on the function of the radar detector. It is good to have a function of setting a display unit that displays an alarm / notification screen based on the function of such a radar detector. Such a setting may, for example, have a function of selecting from "display an alarm / notification screen on both the first display unit 4a and the second display unit 4b", "display an alarm / notification screen on the first display unit 4a", and "display an alarm / notification screen on the second display unit 4b". The setting may be simple if it is possible to select any two of the three types exemplified, for example, but it is more preferable to be configured so that all three types can be selected. Also, when the function of making such a setting is not provided, for example, it is good to configure so that a screen based on the function of the radar detector is displayed only on the second display unit 4b. By doing so, while displaying a predetermined camera image, an alarm screen is displayed on the second display unit 4b on the driver's side of the right-hand vehicle, so that the driver can easily recognize the alarm screen.

[0273] [Radar detector with multiple screens (form where the total number of cameras is more than the number of display units)] A radar detector having a plurality of display units regardless of the presence or absence of a drive recorder function. For example, when the total number of built-in cameras installed in Case 2 and external cameras connected to Case 2 is more than the number of display units (in this form, 2) (in this form, 3 or more), it is good to have a function of displaying video data captured by a predetermined camera equal to or less than the number of display units on a predetermined display unit based on the conditions set in the case of being more. By switching the camera to be displayed according to a predetermined condition and displaying it on a predetermined display unit, for example, an appropriate video can be displayed.

[0274] For example, when there are two display units as in this embodiment and four cameras that respectively capture images of the front, rear, left, and right, it is preferable to have a function of selecting videos from two predetermined cameras and displaying them on a predetermined display unit. The imaging areas of the cameras that respectively capture images in the left and right directions may not be directly lateral, but may be, for example, diagonally forward to the left or diagonally forward to the right. These imaging areas may include areas that are blind spots or difficult to see from the driver. The two predetermined cameras that output the video to be displayed on the display unit may be, for example, the front of the vehicle and the camera that captures the direction in which the vehicle is about to travel. The direction to be captured in a predetermined direction in which the vehicle is about to travel may be determined, for example, based on the turn signal output by the OBD information and vehicle information. For example, when the turn signal is for a left turn, the control unit displays the video data from the camera that captures the left side on a predetermined display unit. When the turn signal is for a right turn, the control unit displays the video data from the camera that captures the right side on a predetermined display unit. Based on the signal of the shift lever position output by the OBD information and vehicle information, when the signal is in the R range, the control unit displays the video data from the camera that captures the rear on a predetermined display unit.

[0275] For example, when configured to display the videos of the camera that captures the front and the camera that captures the rear on the display unit respectively when going straight forward, since the video data of the camera to be displayed is the same both when going straight and when reversing, it is okay to perform the same switching display operation without performing control based on the signal of the shift lever position.

[0276] A predetermined display unit that displays the image of the camera based on the traveling direction preferably has a function of being switched by setting. For example, when it cannot be switched or as a default, the video data from the camera that shoots forward is displayed on the first display unit 4a far from the driver's seat, and the video data from the camera that can shoot left, right, or rear is displayed on the second display unit 4b close to the driver's seat. By doing so, the video that captures the area in the direction in which the vehicle is about to travel is displayed at a position close to the driver, which is easy for the driver to see and easy for the driver to confirm. Since the video data of the forward shot is also an area that the driver can originally directly view through the windshield, even if it is displayed at a position far from the driver, the influence of being difficult to see is small.

[0277] Also, as another display form, for example, on one display unit, the video data from the camera that meets a predetermined condition is displayed, and on the other display unit, the screen is divided into a plurality of parts and the video data from a plurality of cameras is reduced and displayed. The video data from the camera that meets the predetermined condition may be switched, for example, in a predetermined order or randomly, but it is more preferable to use the video data from the camera that captures the traveling direction of the vehicle described above because it becomes a useful video for driving. The one display unit that displays the video from the camera that meets the predetermined condition is preferably the first display unit 4a on the side far from the driver's seat in a vehicle with a right-hand drive, and the other display unit that reduces and simultaneously displays the video data from a plurality of cameras is preferably the second display unit 4b close to the driver's seat side in a vehicle with a right-hand drive (see Fig. 34(a)). By reducing the display, each divided display becomes smaller, but by reducing the display closer to the driver's seat, it is possible to suppress the driver from having difficulty seeing. In Fig. 34, the video data to be displayed on each display unit is shown by alphabets (a, b, c, d) for convenience.

[0278] As shown in FIG. 34(a), for example, when the second display unit 4b is divided into four parts, video data from four cameras can be displayed simultaneously. Further, as shown in FIG. 34(b), in each of the four-divided videos in the second display unit 4b, a video corresponding to the video data displayed on the first display unit 4a may be surrounded by, for example, a first instruction frame 90 of a predetermined color. By doing so, it is good because it is easy to understand which of the four-divided and displayed videos is enlarged and displayed on the first display unit 4a.

[0279] Furthermore, as shown in FIG. 34(c), it is good to display a second instruction frame 91 so as to surround the outer periphery of the first display unit 4a corresponding to the display of the first instruction frame 90. By doing so, it is good because the correlation between the video data being displayed on the first display unit 4a and the video data of one video divided and displayed on the second display unit 4b becomes easy to understand. It is preferable that the display colors of the first instruction frame 90 and the second instruction frame 91 are of the same color system, and it is more preferable that they are the same color.

[0280] When the display colors of the first instruction frame 90 and the second instruction frame 91 are of the same color system or the same color, it is more preferable to assign different colors according to the four display positions of the second display unit 4b to be divided and displayed, or the four cameras. By doing so, when the camera to be displayed on the first display unit 4a is switched, the display colors of the first instruction frame 90 and the second instruction frame 91 change, so it is possible to intuitively understand that the camera has been switched, and it is good because it is possible to understand which camera's video from the display color.

[0281] In the above-described embodiment, a video input terminal is provided and an external camera is connected by wire, but it is good to connect the external camera by wireless communication to make it wireless. The camera may not be built into the case 2, and the video from the external camera may be captured. By doing so, for example, the camera can be installed at a predetermined position such as the information center of the front glass, and the main body equipped with the display unit can be arranged at a position that is easy for the driver to see, for example, on the dashboard. In particular, by making it wireless, it is good because there is no need to route the wiring.

[0282] [For the upper and lower inversion correspondence of the two-screen radar detector 1] The above-described two-screen radar detector 1 is, for example, in a state where a predetermined bracket 3 is attached to the bottom surface side of the main body case 2 as shown in FIG. 35(a), and the bottom surface of the bracket 3 is fixed onto the dashboard of the vehicle with a predetermined fixing member. In FIG. 35, the video data to be displayed on each display unit is shown by alphabets (A, B) for convenience. Further, this radar detector 1 may be configured to be attached and fixed to the back side of the sun visor, the back side of the rearview mirror, the windshield, etc. using another bracket 3.

[0283] In this case, as shown in FIG. 35(b), since the radar detector 1 is attached to the vehicle in an upside-down posture with the bottom surface side of the case 2 facing up, the positions of the first display unit 4a and the second display unit 4b as seen from the driver's side are also arranged with the left and right reversed. Therefore, the control unit 18 of the radar detector 1 performs control to reverse the left and right and invert the up and down of the images displayed on the first display unit 4a and the second display unit 4b according to the up and down orientation of the radar detector 1. By doing so, regardless of the mounting posture of the radar detector 1, the same display content can be notified on the side closer to the driver, and for example, the information that the driver wants to show can be arranged on the driver's side. Similarly, regardless of the mounting posture of the radar detector 1, the same display content can be notified on the side farther from the driver. The up and down orientation may be detected by, for example, a G-sensor.

[0284] The display control function of this radar detector may be implemented regardless of the presence or absence of the drive recorder function. In particular, in the case of a radar detector with the drive recorder function implemented, it is advisable to use the side closer to the driver for alarm notification regardless of the mounting posture of the radar detector.

[0285] [Camera Position of Two-Screen Radar Detector 1] For example, as shown in FIG. 33(c), the mounting position of the camera 8 may be shifted from the center in the left-right direction and arranged directly behind the first display unit 4a. If the video captured by the camera is displayed on the first display unit 4a, it is good because it can create the feeling of looking through the first display unit 4a. When having a function to switch and set the display unit for displaying the video captured by the camera, it is good to set the default to display on the first display unit 4a.

[0286] [ASIC-mounted radar detector] The circuits of the various radar detectors described above may be the same as those conventionally adopted, but it is even better to make them integrated into one chip. As components built into the chip, for example, it is good to include LNA, MIXER, VCO, IF AMP, IF detection, signal processing, FSK (K-band orbis identification), etc. By doing so, effects such as miniaturization, cost reduction, reduction of the number of components, performance stabilization, and prevention of circuit copying can be achieved.

[0287] [VCO temperature compensation built into ASIC] Among the various radar detectors described above, there is a type with an ASIC mounted. The varicap capacitance inside the VCO built into such an ASIC varies due to temperature changes, and accordingly, the oscillation frequency of the VOC varies. To solve this problem, it is good to have a function to compensate for the frequency shift due to temperature changes with an external element.

[0288] For such a compensation function, for example, it is good to use the input terminal (Vcont) for setting the VCO provided in the ASIC. The VCO outputs a signal with an oscillation frequency corresponding to the voltage value input to Vcont. Therefore, by mounting, for example, a temperature sensor on the radar detector etc. to have a function to detect the ambient temperature and a function to adjust the voltage value input to Vcont based on the detected ambient temperature, it is good to realize the NTC thermistor and LTC compensation method using the input of Vcont. With such a configuration, correction is possible within a certain voltage range (for example, 0.5 to 2.5V), and fluctuations can be suppressed. Since voltage division is used, the effect is difficult to appear at low voltages, but it is good as long as it is above a predetermined voltage.

[0289] Also, it is advisable to use the input terminal (Vadj) for adjusting the VCO. When a predetermined voltage is input to the Vadj terminal of the VCO, the oscillation frequency is changed and adjusted according to the input voltage value. Therefore, for example, a temperature sensor is installed in a radar detector or the like to detect the ambient temperature, and a function of adjusting the voltage value input to Vadj based on the detected ambient temperature is provided, so that it is advisable to realize an NTC thermistor and an LTC compensation method using the input of Vadj. With such a configuration, correction is possible within all voltage ranges (for example, 0 to 3V), and fluctuations can be suppressed. By using LTC, linear compensation is possible, and it hardly fluctuates from around room temperature.

[0290] [Utilize information on disasters distributed from GPS (Michibiki), etc.] One of the services provided by Michibiki (Quasi-Zenith Satellite System) QZSS is the disaster and crisis management notification service. This disaster and crisis management notification service is a service that transmits disaster information such as earthquakes and tsunamis, crisis management information such as terrorism, and the issuance status of evacuation advisories from disaster prevention and crisis management government agencies via Michibiki. This service delivers messages such as disaster information to users, and the signal for transmitting the disaster and crisis management notification (hereinafter referred to as "disaster and crisis notification") has the same frequency and the same waveform as the signal transmitted from GPS satellites generally used in satellite positioning. Therefore, for example, various radar detectors and GPS devices equipped with a GPS unit such as a navigation system and a drive recorder can receive the disaster and crisis notification with the GPS unit.

[0291] For example, it is assumed that the power grid is damaged and the mobile network cannot be used during a disaster. On the other hand, a vehicle functions as a power source for a GPS device or the like as long as there is fuel. Also, the GPS device can be battery-powered. It is advisable for a radar detector and other GPS devices to have a function of receiving the disaster and crisis notification and a notification function of performing notification based on the received disaster and crisis notification.

[0292] For example, in Kagoshima Prefecture, volcanic ash fall from Mount Kirishima and Sakurajima has become a problem, and volcanic ash fall is so closely related to daily life that volcanic ash fall predictions are announced in weather forecasts, and checking volcanic ash fall predictions has become part of daily life. It would be good if information regarding this volcanic ash fall could be notified. For example, it would be good to notify the cause location and the predicted amount of volcanic ash fall, such as "Currently, a large amount of volcanic ash fall is expected from Mount Kirishima."

[0293] The notification timing should preferably be configured to notify when the engine is turned off when parking. It would be good to operate it with a battery backup at the time of power cut such as when the engine is turned off and notify disaster prevention weather information (volcanic ash fall).

[0294] For example, when the engine is off, it is good to notify disaster prevention weather information (volcanic ash fall) such as "Currently, a large amount of volcanic ash fall is expected from Mount Kirishima." and information such as the source of the disaster risk and the situation / degree. In particular, it is good to notify a caution message regarding the next action to be taken, such as "Let's take in the laundry." When the engine is turned off, people often get out of the car immediately, the vehicle is parked, and the driver etc. often enter a house such as their own home as it is. Therefore, by notifying at that timing, it is good because it is easy for users such as drivers to move on to the next action.

[0295] It is also possible to notify when the engine is started, but preferably when the engine is turned off. For example, when the engine is started, since the vehicle is about to start and go somewhere, if we assume that the house will be left empty and away from home for a certain period of time, notifying disaster prevention weather information (volcanic ash fall) at that timing may give an opportunity to take measures against volcanic ash fall such as taking in the laundry and then start again, but since there may be no time and one may be in a hurry to go out, it is more preferable to notify when the engine is turned off when there is more time available later, such as when returning home. Also, when the engine is off, measures such as putting the vehicle in a place with a roof such as a carport or covering the vehicle can be taken in advance when getting out of the car. It is good that measures such as immediately taking in the laundry can also be taken. Disaster prevention meteorological information (ash fall) also includes information on the predicted amount of ash fall. The predicted amount of ash fall is divided into four levels from 1 to 4. For example, 1 is "a small amount of ash fall", 2 is "a somewhat large amount of ash fall", 3 is "a large amount of ash fall", and 4 is "the fall of small pyroclastic bombs". GPS devices such as radar detectors should preferably have a function to change the alarm according to the degree. For example, it may be set that there is no notification for level 1, and notifications are made for levels 2 and 3. In the case of level 4, since evacuation is necessary, no notification of disaster prevention meteorological information (ash fall) should be made, and an alarm to prompt evacuation should be issued instead of the notification of disaster prevention meteorological information (ash fall). Also, it is advisable to make notifications only when the region and time zone correspond to the current location and current time.

[0296] (Cooperation with wireless alarms) The control unit of a radar detector etc. should preferably have a function to cooperate and notify the wireless alarm and the Michibiki information. The Michibiki information may be, for example, the issuance of a volcanic eruption alarm, ash fall information, etc. For example, it is good to associate and notify the content of a predetermined disaster danger notification such as volcanic eruption information issued from Michibiki with the wireless information, because it can enhance the attention - arousal based on both alarms.

[0297] As the timing of the alarm, when a predetermined wireless is received and a predetermined Michibiki information (for example, the issuance of a volcanic eruption alarm, ash fall information, etc.) is received, it should preferably have a function to also notify that predetermined Michibiki information. For example, at the timing of issuing a wireless alarm, read out the Michibiki information by TTS etc. For example, it is good to notify in voice, telop, or other text such as "Digital wireless has been received. Also, a volcanic eruption alarm has been issued for Kirishima - yama (Mt. Ontake). Please drive carefully." Receiving a predetermined wireless may mean that administrative activities are likely to be active. If a volcanic eruption alarm etc. is issued at that time, the possibility of administrative activities and volcanic eruption countermeasures is high. For example, it is good to be able to take countermeasures such as driving on a route where traffic jams are expected or a route that does not interfere with administrative activities.

[0298] When receiving the specified information of Michibiki, it may be notified, but since it is sent regularly, the same warning will be repeated. Therefore, if it is notified every time the specified information of guidance is received, there is a risk that the notification will be frequently performed, causing annoyance or reducing the effect of the warning. Therefore, it is advisable to issue a warning based on the same information only when the specified warning conditions are met after one warning. The specified warning conditions may be, for example, the elapse of a specified period. By doing so, there will be no warning for at least the specified period, so it will not be noisy. The specified period includes time, number of times, etc. Also, the specified warning conditions may be that another warning has been issued. In particular, it is advisable to link with a radio warning associated with radio reception because the relevance and relationship are high. In particular, it is advisable to use administrative radio such as police, fire, and helicopter.

[0299] (Notification function based on tsunami and river flood) One of the specified information of Michibiki is the "tsunami warning", and a very large number of types are regulated regarding the content of the "tsunami warning". For example, there is "A tsunami of the 2011 Great East Japan Earthquake class is approaching".

[0300] A radar detector or the like stores and holds information with coastline information on a map. When a tsunami warning is issued near the current location, the control unit of the radar detector or the like preferably has a function of emitting an alarm sound indicating that the current location is dangerous, such as "Please move away from the sea", at the time of issuing the content of the tsunami warning. It is advisable to use a message to convey that the tsunami will reach here (the current location). For example, it is advisable to notify the actions to be taken currently, such as "Please head towards the mountains" and "Please take shelter at a high position".

[0301] On the other hand, when the current location is sufficiently far from the sea, it is more preferable to have a function of suppressing the warning indicating that the current location is dangerous. The suppression of the warning may be not to issue a warning, but it is advisable to use a screen for notification without a voice warning.

[0302] For example, alarms may be issued uniformly in a certain regional unit such as a municipality when a disaster danger notification is received. However, even in the same region, there are areas with high elevations such as on mountains, and places far from the coastline where the possibility of a tsunami reaching is low. If such low - possibility places are also notified, there is a risk of panicking, confusing the driver, or causing unnecessary evacuation behavior. Therefore, it is better to specialize the notification to dangerous areas, such as a location close to the coastline as described above, based on the current location.

[0303] Instead of the function of issuing tsunami warnings based on the distance from the coastline described above, the warning function may be provided based on elevation. More preferably, it is good to have both a notification function based on the distance from the coastline and a notification function based on elevation. Even more preferably, it has a function of issuing notifications based on both pieces of information.

[0304] For example, for the notification based on elevation, contour line data may be stored in a map. When the current location is below the height corresponding to the largest - scale tsunami, an alarm voice indicating that "the current location is dangerous" may be issued. In areas with low elevations, even if they are far from the coastline, there is a risk of seawater intrusion, etc., so it is advisable to raise awareness for those areas. The height below the height corresponding to the largest - scale tsunami may be, for example, less than 20 m above sea level.

[0305] The function of giving notifications based on both pieces of information is, for example, to give a notification when at least one of the conditions is met. When both notification conditions are satisfied, such as being near the coastline and having a low altitude, it is advisable to give a stronger notification indicating a higher level of urgency. Also, for example, even within a certain distance range from the coastline, if the altitude is higher than the height corresponding to the largest tsunamis, it is better not to issue a tsunami warning. More preferably, it is good to give a notification to indicate such a state. Giving a notification to indicate such a state means, for example, giving a notification that "a tsunami has occurred or there is a risk of occurrence, and the current location is near the coastline but the altitude is high". For example, even if one moves in a direction away from the coastline when a tsunami warning is given, if the altitude of the area in the moving direction becomes lower, there is a risk that the tsunami will reach before moving to a safe distance from the coastline, and in some cases, it may be safer to stay at the current location with the altitude when the tsunami warning was given. Therefore, for example, by notifying the distance from the current location to the coastline and the altitude as specific numerical values, useful information can be provided to allow the user to judge which is safer, moving away from the coastline or waiting there.

[0306] Although the above examples have explained notifications based on tsunamis, the same can be applied to river floods with reference to the position of the river and the altitude of the river.

[0307] (Combined use of position information and notification level) The control unit such as a radar detector should have a function of determining whether the direction (dangerous location: disaster area) of an earthquake, tsunami, volcanic eruption, flood, etc. is near the current location or in the direction currently heading, and giving a notification if it is the case, and suppressing the notification if it is not.

[0308] This form gives a notification when the location that will exist in the near future rather than the current location is dangerous. For example, when a destination is set like in a car navigation system, it can give a notification based on the planned driving route. When no destination is set, it is advisable to predict the approximate direction one is heading based on, for example, the driving history from the departure place, etc., and give a notification if there is a dangerous location ahead in that direction.

[0309] In the disaster and crisis management notification service of Michibiki, emergency earthquake early warnings, tsunami warnings, volcanic eruption notice information, meteorological warnings, and flood information are distributed, and three notification levels, namely highest priority, high priority, and normal, are defined in the regulations. Therefore, it is advisable to change the notification target area according to the priority levels of highest priority, high priority, and normal. For example, for the highest priority, it is more preferable to notify even if it is not near the current location.

[0310] (Evacuation function) It is linked with a radar detector and a vehicle destination setting function, and the radar detector has a function of inputting an area without disaster information as the destination to the destination setting function. In the case of a vehicle with an automatic driving function, when the current location is in a disaster area, the vehicle is moved to an area without disaster information by automatic driving. When there are people in the vehicle, it is advisable to ask whether to move. When there are no people in the vehicle such as during parking, the vehicle should be moved to the nearest safe area.

[0311] (Link with the drive recorder) It is advisable to have a function of recording in the drive recorder log that a notification based on a disaster and crisis notification has been made. By recording event records based on the disaster and crisis notification, it becomes possible to record the situation of disasters and the like that are the basis of the disaster and crisis notification.

[0312] For example, the radar detector and the drive recorder are linked, and the radar detector that has made a notification based on a disaster and crisis notification notifies the drive recorder of the fact of the notification and its content. The drive recorder performs event recording of recording a predetermined period before and after the notification based on the notification, and records the notification content in association. By doing so, when the user or the like views the log later, for example, the location at the time of notification can be known, the user can recall that it was not dangerous, and can confirm that they were able to avoid danger safely.

[0313] In particular, it is preferable to have a function of recording event records based on giving disaster danger notifications to a drive recorder equipped with a camera for photographing inside the vehicle. When photographing inside the vehicle with the drive recorder, it is possible to record the state of the driver and passengers. For example, it can be used to later check how panicked one was when a notification based on a disaster danger notification was given, or for research on how people behave.

[0314] The communication for transmitting the occurrence of a disaster is not limited to the disaster danger communication sent from the satellite described above. For example, it may use the V-ALERT (registered trademark) of the local government disaster prevention information media using the new broadcast service i-dio or other various means, but it is particularly good to use the disaster danger communication. The disaster danger communication covers the whole country, and it is possible to know a lot of detailed information about the type and degree of the disaster to be notified, and since it can be received using the GPS unit originally installed in the radar detector, it is not necessary to install a special receiver separately.

[0315] [Passenger recognition function] It is preferable that the various radar detectors and the like described above have a function of recognizing passengers entering the vehicle, and it is preferable to have a function of giving different alarms according to the recognized passengers. By doing so, it is possible to give an alarm suitable for the entering passengers. The passenger recognition function may be performed, for example, by mounting a camera and performing face or person authentication based on the photographed image data. Different alarms may be, for example, to discriminate passengers and change the alarm content. The change in the alarm content may be, for example, in a radar detector equipped with a function of displaying a character and notifying by the movement, posture change, or voice of the character, to give a notification using a character suitable for the passenger, or to switch the presence or absence of the notification of the character.

[0316] Different alarms may, for example, be equipped with a function to switch to content for men and women, young people, or the elderly. For example, for the elderly, alarms that are once stopped, temporarily stopped, or have enhanced reverse driving compared to regular ones may be issued. For young people, alarms that are enhanced for speeding violations and the like may be issued. It is advisable to register individual preferences and issue alarms according to the content of the registered preferences for the passengers. Also, when a person without registration drives, a theft alarm may be issued. This enables theft prevention measures.

[0317] [Built-in i-dio tuner] Each of the various radar detectors and the like described above may be equipped with a function to be built into an i-dio tuner and connected to a car audio by wired or wireless communication. For wireless communication, for example, Bluetooth (registered trademark) may be used. The control unit has a function to output the sound received by the i-dio tuner from the car audio and display the information sent by data broadcasting on the display unit. It is advisable to display it on the display unit of the radar detector as one of the standby screens. It is preferable to display the screen of the free digital broadcast service Amanek Channel for car enthusiasts and those who like to go out.

[0318] The radar detector outputs an alarm sound from the internal speaker. Normally, the sound received by the tuner is output from the car audio, and during an alarm, it is advisable to output the alarm sound from both the built-in speaker and the car audio. When an alarm is received, it is better to switch the music and the like received by the i-dio tuner to be output from the built-in speaker and output the alarm from the car audio. Since the driver focuses on listening to the sound from the car audio, if the alarm sound or voice is output from that car audio, the alarm effect is enhanced, which is good. Since the music and the like that were previously output from the car audio are switched to be output from the built-in speaker, the continuity of the music can be maintained, which is good.

[0319] [Built-in door mirror type] Each of the above-described various radar detectors and the like may be incorporated in the door mirror. When incorporated in the door mirror, a display may be provided on the mirror surface for display, or the mirror may be a half mirror, and a display unit may be arranged on the back side thereof. In a state where the display unit is lit, the display content of the display unit can be visually recognized through the half mirror, and in a non-display state, the entire surface may be configured to function as a mirror.

[0320] [Flip-down monitor] Each of the above-described various radar detectors and the like is provided with a flip-down monitor that automatically opens and closes with respect to the main body, and the main body is attached to a predetermined position of the vehicle. The main body is attached to, for example, the sun visor or the windshield using a predetermined mounting bracket. When the main body is attached to a predetermined position of the vehicle, when the monitor is closed, the monitor is in a state substantially parallel to the ceiling or the floor surface of the vehicle, reducing the area that enters the driver's field of vision and suppressing the feeling of being obstructive. During an alarm, a motor that opens and closes the monitor is driven to open the monitor, and an alarm screen is displayed on the display unit of the monitor. When the alarm ends, it is preferable to configure the motor to be driven to return the monitor to the closed state.

[0321] [Mounting type for a room mirror with an existing monitor] Each of the above-described various radar detectors and the like is a radar detector of a room mirror mounting type, and when attached to a room mirror equipped with an existing monitor, it is preferable to have a structure that does not block the existing monitor. By doing so, the radar detector can be attached without impairing the visibility of the existing monitor for a room mirror with an existing monitor, making it available even for users who dislike the type installed on the dashboard.

[0322] The structure that does not block the existing monitor may, for example, have an open space in the part facing the existing monitor. In particular, it is advisable to configure part or all of the display of the radar detector with transparent EL and arrange the transparent EL display in front of the existing monitor. By doing so, for example, even an existing monitor that occupies a large area relative to the rearview mirror can ensure visibility. In the configuration using transparent EL, when the existing monitor is lit, it is better to have a function to control so that the transparent EL is not lit and is made transparent and non-displayed.

[0323] [Radar Detector with USB Output Terminal] The various radar detectors and the like described above are preferably provided with a micro-USB power output terminal. By doing so, for example, it is possible to connect a smartphone or other portable terminal device and charge it.

[0324] [Function for Suppressing Misrecognition of Acceleration Sensor of Drive Recorder Associated with Sound, etc.] The sound generated inside the vehicle is transmitted to the acceleration sensor and may be misrecognized as the vibration of the vehicle, affecting event recording. For example, the reproduction of music at a high volume and the case of low bass have a great impact. In particular, for example, in a radar detector integrated with a drive recorder, when a part that generates sound, such as a speaker that outputs the warning sound of the detector, and the acceleration sensor of the drive recorder are mounted in the same housing, there is a problem that the sound generated in the same housing enters the acceleration sensor and hinders impact detection.

[0325] In this embodiment, in order to solve such problems, it has a function of adding the opposite phase of the sound. The sound is, for example, picked up by a microphone for external sounds, and when outputting its own sound such as a warning sound, the output sound is used. These sounds are input to a processing unit that generates the opposite phase, and the opposite phase generated by the processing unit is added to the acceleration sensor to cancel it out.

[0326] Another solution is to suppress malfunction based on self-generated sounds, such as the warning sound in a radar detector integrated with a drive recorder. When the sound generation is temporary, it is advisable to perform control without acceleration detection during the period when the sound is emitted, such as during an alarm. By doing so, the problem can be solved with a simple configuration.

[0327] For example, the impact on the drive recorder function based on the warning sound in a radar detector integrated with a drive recorder also hinders the recording of environmental sounds in the drive recorder, in addition to the acceleration sensor described above. The warning sound of the detector leaks into the microphone of the drive recorder, hindering the recording of environmental sounds. To solve such problems, it is equipped with a function of adding the inverse phase of the warning sound to the detection signal by the microphone

[0328] [Device with Radio Wave Emission Function Integrated with Drive Recorder] For example, in a device equipped with a function of emitting radio waves, such as a radar detector or a moving object detection Doppler sensor, a directional antenna is provided. It is advisable to arrange the imaging center of the camera of the drive recorder and the radiation axis of the directional antenna of the device to coincide. By doing so, the radiation direction of the invisible radio waves coincides with the video, so the installation becomes appropriate.

[0329] Furthermore, it is advisable to arrange the radiation angle of the directional antenna to be wider than the viewing angle of the camera. By doing so, it can be recognized that radio waves are flying within the range of the video captured by the camera, which is good. The housing can be made compact. Desirably, the radiation angle of the directional antenna is arranged to be wider than the viewing angle of a camera with a wide half-value angle. When the radiation angle and the half-value angle are the same, it can be understood that the range of the video captured by the camera is their boundary. As an example, for example, when the directional antenna 93 is a patch antenna, it is advisable to arrange each patch 93a constituting the directional antenna 93 and the camera 8 as shown in Fig. 36.

[0330] [Data Communication Method] The various radar detectors and the like described above, for example, update the firmware or update the POI data related to the warning target. A communication device that uses a communication system that manages the data communication for firmware update and the normal communication under different fee systems, and it is advisable to transmit the POI data and the like in the data communication for firmware update. For example, if there is a limit on the capacity that can be sent at one time in the data communication for firmware update and there is room in the capacity for the data capacity of the firmware update data to be sent, it is advisable to send the POI data together.

[0331] For example, a system that distributes POI data regularly distributed from a manufacturer or the like, such as monthly, and POI data based on submissions. The POI data regularly distributed is transmitted by an existing method such as WiFi, while the POI data based on submissions is configured to be transmitted by LPWA.

[0332] In this way, the POI data of the submission can be transmitted in real time using LPWA. The POI data regularly distributed does not have real-time performance and has a large data size, so it is transmitted using, for example, WiFi or the like in the same way as before without using LPWA.

[0333] Since LPWA has a small data capacity delay at one time, it is difficult to send data for the whole country, and it is advisable to narrow it down based on the surroundings and the posting date and time. For example, when acquiring the POI data of the submission, the radar detector sends the location information of the current location to a server or the like that manages the POI data of the submission. The server extracts the POI data around the current location that has been sent and transmits it to the radar detector. The radar detector acquires and stores the transmitted POI data and adds it to the warning target when performing a GPS warning hereafter. It is advisable that the POI data of the submission extracted and sent by the server be limited to those registered recently, such as today, because the transmitted data will also be small.

[0334] The acquisition timing of the submitted POI data may be, for example, to send the location information of the current location to the server every certain period (e.g., 10 minutes), and the server periodically returns the POI data if there is any within the surrounding area of the acquired current location (e.g., within a radius of 5 km or 10 km, etc.). It is advisable to set the certain period for sending the location information of the current location to be longer, such as 1 hour. For example, when the engine is started, the current location is sent to the server, and the server sends the POI data of the submissions within the distance that can be traveled in one hour (e.g., within a 100 km range). The radar detector sends the current location again after a certain period has elapsed. By repeating this process below, the transmission span can be lengthened.

[0335] When starting the engine, send the POIs in a relatively wide range considering highway travel. After the second time and subsequent times, recognize the moving distance and moving direction from the previous current location data, predict the range to move within the next certain period, and send the POI data of the submissions within the predicted range. By doing so, by not sending unnecessary data, the communication capacity can be reduced, and the necessary and sufficient POI data can be transmitted. Rather than sending all of the POI data via LPWA, it is advisable to send only the important POI data such as those related to traffic control. If all of the POI data is sent, it is nearly 2M, which is difficult to send via LPWA. Therefore, by sending only the important POI data such as those related to traffic control, the important POI data can be preferentially and surely transmitted, and it is acceptable for the radar detector to receive it.

[0336] Send the important POI data more frequently than the regular update and send all of the POI data when the radar detector is connected to WiFi. When sending data during WiFi connection, it is advisable to send all of it regardless of whether it is the POI sent in advance or not. By doing so, there is no need to manage the information of the POI sent in advance, the control becomes simple, and when sending via WiFi, even if the total transmission capacity is large, there is not much impact, so it is acceptable.

[0337] It is not known when the WiFi will be connected. The server side updates regularly, for example, once a month. However, if the WiFi is not connected for a long period exceeding the update period, it will result in an alarm based on old POI data, which is not preferable. Therefore, important POI data is actively transmitted using LPWA.

[0338] [Lane notification function] The various radar detectors and the like described above record the lane information of several lanes in association with a predetermined road such as a main road. The radar detector preferably has a function of identifying the road on which the vehicle is currently traveling from the current position information and notifying the lane information such as how many lanes there are on that road if the lane information is registered. For example, it is good to audibly notify the number of lanes such as "This road has ○○ lanes on one side" and the lane status such as "Two-way traffic".

[0339] By doing so, for example, even in a situation where the lanes of the road being traveled are not visible due to rain making the road surface shiny, snow accumulation, or the lines being worn out, the approximate position of the lanes can be known, and driving across lanes can be reduced, which is good. Especially when driving in a place for the first time, even if it is only a main road, if it can be recognized, it is good to drive with confidence. Also, for example, when the number of lanes is large, such as "There are 5 lanes on one side", if you plan to turn right or left at the next intersection or the like, it is better to change lanes to the lane closer to the direction you want to turn earlier and move, so that you don't have to change lanes right before the intersection and panic, and can provide useful information for safe driving. Also, when the number of lanes is large, there may be a right-turn lane or a left-turn lane near the intersection. Therefore, when planning to go straight, it can be known that it is good to drive in the central lane, and there is no need to panic and change lanes near the intersection.

[0340] [Wrong-way driving warning function] The various radar detectors and the like described above preferably have a function of recognizing a no-entry sign by image recognition and giving an alarm when wrong-way driving occurs. Also, at highway entrances and exits, service areas, etc., it is good to register several position coordinates by GPS in advance and judge whether the vehicle has passed through the points in order. If it has not passed through the points in order, it has a function of giving a wrong-way driving alarm.

[0341] [Event recording linked to GPS data] In the case of a device equipped with a driving recorder function, it is advisable to equip it with an event recording function linked to GPS data. The target of event recording is, for example, to input reverse point data into the GPS data, and when reversing, not only to display a warning table on the screen and give an audible notification, but also to enable event recording. In particular, when equipped with a function such as a 360-degree camera that captures the inside of the vehicle, it is good to be able to record the driver's condition at the time of reverse warning notification.

[0342] Also, at a temporary stop point, if the vehicle speed does not reach a complete stop of 0 km / h, enable event recording. This is also a point where accidents often occur, and it is advisable to record events even for minor contacts with bicycles, pedestrians, etc.

[0343] Also, when passing a vehicle speed measuring device such as Orbis, if the speed limit is exceeded, event recording can be used to confirm after passing. It is possible to confirm at what speed the vehicle was traveling, and if there is no consistency with the speed captured by the vehicle speed measuring device, it can serve as the basis for claiming the actual driving speed. Also, it is advisable to record events when the speed limit is not exceeded. By doing so, it can serve as evidence that the vehicle was traveling within the speed limit.

[0344] [Self-vehicle position correction function during non-positioning using images] In the case of a long tunnel such as a bridge junction, GPS information becomes non-positionable, and an alarm based on GPS information cannot be issued. In such a case, there is a radar detector equipped with a function of obtaining the travel distance and direction based on OBD information, estimating the current position, and issuing an approach alarm for the alarm target based on this. In the estimation of the current position based on OBD information, for example, the alarm position may deviate slightly in units of several centimeters. To solve such problems, for example, it is advisable to have a function of mounting a camera or performing image recognition on video data captured by a camera of another in-vehicle device, correcting the position of the own vehicle with the video of a feature location such as an exit, an entrance, or a branch point in the tunnel, so as to be able to issue an accurate alarm. With such a correction function, even a radar detector not connected to OBD can issue an alarm at an appropriate position in the tunnel or the like. It is advisable to correct the current position based on an emergency exit, a digital display board, or other signboards. In this case, when there are a plurality of the same type of signboards or the like in the tunnel or the like, for example, it is advisable to count the number after entering the tunnel and correct the current position.

[0345] [Power consumption saving function during parking monitoring] In the case of a radar detector integrated with a drive recorder, the power ON / OFF is common. For example, when the power is turned on with the start of the engine, both the drive recorder function and the radar detector function operate, and when the engine is turned off, the power of the main body is turned off and both the drive recorder function and the radar detector function stop. In such a case, for example, when parking recording is performed with a radar detector integrated with a drive recorder, since the power of the main body continues to be ON even when the vehicle is parked, both the drive recorder function and the radar detector function operate, resulting in a problem of increased battery consumption.

[0346] Therefore, in this embodiment, for example, it is advisable to have a function of turning off the screen of the display unit to suppress power consumption. Also, it is advisable to have a function of turning off the receiving functions such as wireless and radar waves and operating only the drive recorder without issuing an alarm or the like to suppress power consumption.
