Description

Technical Field

[0001] The present invention relates to a system and a program for notifying when an alarm condition is satisfied.

Background Art

[0002] In recent years, a large number of speed measurement devices for measuring the speed of automobiles have been installed on the roadside and the like. As an example of a speed measurement device, microwaves in a predetermined frequency band are emitted toward a vehicle, and the reflected wave is received to measure the traveling speed of the vehicle.

[0003] On the other hand, in order to detect the presence of such a speed measurement device, a microwave detector configured to detect microwaves emitted from the speed measurement device and output an alarm has been conventionally known. However, depending on the installation position of the speed measurement device, the state of the road, and other surrounding environments, some conventional microwave detectors can detect from a relatively long distance, while others are difficult to detect unless they are relatively close.

[0004] In addition, some speed measurement devices cannot be detected by conventional microwave detectors. For example, as called a loop type, a loop-shaped coil is embedded in the ground, and when a vehicle passes over the coil, the vehicle speed is detected and determined. There are also those that detect the speed of a vehicle using light other than microwaves.

[0005] Therefore, recently, there is in-vehicle electronic equipment that stores in advance the installation position information of a speed measurement device and issues a warning regardless of the detection of microwaves when the current position approaches the installation position stored using GPS (Global Positioning System) information (when a predetermined relationship is established) (Patent Document 1).

[0006] For example, when the current position enters within 1000 m from the installation position of the speed measurement device, a first warning is given, and when it further enters within 500 m from the installation position of the speed measurement device, a second warning is given, and so on.

[0007] As specific notification modes, for example, relative positional relationships such as "Highway H system 1 km ahead to the left" and "General road N system just ahead" are output as voice information from a speaker, or content specifying the target content, or characters or images directly representing those warning targets are displayed on the display unit. Images directly representing the warning targets include actual photos of the warning targets such as speed measurement devices and images imitating them.

[0008] Furthermore, as the screen size of the display unit increases and it becomes a color screen, the types and amounts of information output using the display unit are also increasing. An example of the information to be output is a map around the position of the own vehicle. By superimposing a mark indicating the position of the own vehicle and marks (2D, 3D) indicating the warning targets on such a map, a specific positional relationship can be recognized. Furthermore, the background color is changed according to the type of warning target being notified, and when the distance to the warning target becomes closer than a reference value, the background color is changed to red.

Summary of the Invention

Problems to be Solved by the Invention

[0010] In conventional devices, as the screen size of the display unit increases, the amount of information provided using the display unit also increases. However, since a driver in operation needs to look at the surroundings of the vehicle ahead and other vehicles, it is difficult to focus on such a display unit, and it may be difficult to instantaneously understand the content of the provided information. For example, when a large number of pieces of information are output to the display unit at once, the user may not be able to view all the displayed information and may miss important information. Also, when a map is being displayed on the display unit, if the distance between the current position and the warning target becomes equal to or less than a reference distance and the background color is changed to red or the like, the map becomes difficult to view. In particular, in the case of a map, roads and the like are color-coded, and when the color of the road and the changed background color are of the same color system, there are various problems such as it becoming even more difficult to view.

Means for Solving the Problem

[0011] In order to solve the above-described problems, a system according to the present invention is a system including (0) a function of causing information to be displayed on a display screen and a function of controlling a light emission state of a light emitting unit to perform warning notification when a warning condition is satisfied. As the control of the light emission state, the system has a function of emitting light in a light emission color corresponding to a warning target that satisfies the warning condition, and a function of causing a display of a color system similar to the light emission color of the light emitting unit to be displayed on the display screen when the warning condition is satisfied, and the light emitting unit is configured such that a logo emits light in the light emission color. A system including a function of causing information to be displayed on a display screen and a function of controlling a light emission state of a light emitting unit to perform warning notification when a warning condition is satisfied. As the control of the light emission state, the system has a function of emitting light in a light emission color corresponding to a warning target that satisfies the warning condition, and a function of causing a display of a color system similar to the light emission color of the light emitting unit to be displayed on the display screen when the warning condition is satisfied, and the light emitting unit is configured such that a peripheral area including a logo emits light in the light emission color. (1) A system including control means for controlling a light emission state of a light emitting unit having an LED as a light source to perform warning notification when a warning condition is satisfied, wherein the control of the light emission state is such that the light emitting unit emits light in a light emission color corresponding to a warning target that satisfies the warning condition.

[0012] The light-emitting part equipped with an LED means that the light source of the light-emitting part is an LED. When the LED is exposed, the LED itself becomes the light-emitting part. When the LED is built into the case body (housing) of the device, the area where it can be seen that light is emitted from outside the case body becomes the light-emitting part. In the latter case, for example, a predetermined area on the surface of the case body becomes the light-emitting part. Such a predetermined area may be configured, for example, by making the wall surface of the case body thin so that light from the LED can pass through, or by opening a window hole in the wall surface of the case body and attaching a cover made of a member that allows light such as semi-transparent light to pass through the window hole.

[0013] The light-emitting part emits light in a light-emitting color corresponding to the warning target that satisfies the warning condition. For example, relationship information associating the warning target and the light-emitting color information is stored and held in a predetermined storage means. The light-emitting color information is information specifying what the light-emitting color is. When the warning condition is satisfied, the control means accesses the storage means and obtains the light-emitting color information corresponding to the warning target that satisfies the warning condition from the relationship information stored and held, and controls the light emission of the LED so that it becomes the light-emitting color specified by the light-emitting color information. The warning condition is, for example, based on position information such as the positional relationship between the warning target and the current position being in a predetermined proximity relationship, or not based on position information such as the reception of a predetermined radio wave or wireless signal, the state or driving state of the vehicle. Examples of those not based on position information include those based on information from outside the vehicle such as the reception of a predetermined radio wave, and those based on information inside the vehicle (the vehicle itself or the driver) such as dangerous driving like sudden acceleration or sudden steering (the sensor value of the acceleration sensor is above the reference value), and poor fuel consumption driving. There are those not based on position information such as those based on information from outside the vehicle such as the reception of a predetermined radio wave, and those based on information inside the vehicle (the vehicle itself or the driver) such as dangerous driving like sudden acceleration or sudden steering (the sensor value of the acceleration sensor is above the reference value), and poor fuel consumption driving.

[0014] It is the light emission color corresponding to the warning target. In the case of a warning target based on position information, for example, the light emission color may be set (associated) for each warning target for which position information is registered, or the light emission color may be set for each type of warning target. Also, when considering each type of warning target, as partially exemplified in the embodiment, it may be set in detail by type, such as a fixed speed measuring device (radar), N system, traffic monitoring point, checkpoint area, roadside station, etc. Or, it may be divided into a plurality of groups according to the importance (degree of danger), and the light emission color may be set for each group, and the warning targets belonging to the same group may have the same light emission color. The association of the light emission color based on the importance may be, for example, red for those with high importance such as speed measuring devices, blue for those with medium importance (giving attention) such as the N system, and green for those with low demand (information provision level) such as roadside stations, etc.

[0015] During driving, the driver needs to pay attention to the surroundings of the vehicle ahead and other vehicles. In the present invention, when the warning condition is satisfied, the light emitting part emits light in the light emission color corresponding to the warning target. Therefore, even if the device (light emitting part) of this system is not within the driver's field of vision, the driver can know that it has emitted light, and by simply shifting the line of sight a little, the driver can capture the light emitting part within the field of vision and confirm its light emission color. As a result, it is possible to know that a warning target satisfying the warning condition exists in the surroundings, and what the warning target is, etc. Instead of a large number of warning information being notified, and since it is a simple warning of emitting light in a predetermined light emission color, the driver can understand the warning content without staring at the light emitting part for a long time, and thus can focus on collecting the information necessary for driving inside and outside the vehicle.

[0016] (2) The LED is a color LED, and the control means may gradually change the emission color according to the alarm level. By using a color LED, it is possible to represent a variety of colors with a single LED. For example, when using RGB three-primary-color LEDs and performing color intensity control using PWM, if R is 5 bits, G is 5 bits, and B is 5 bits for a total of 15 bits, color control of 32,768 colors can be realized. If R is 8 bits, G is 8 bits, and B is 8 bits for a total of 24 bits, color control of 16,777,216 colors becomes possible. Therefore, it is possible to issue an alarm such that the emission color gradually changes by smoothly performing gradation control from a low alarm level to a high alarm level. When notifying information about the alarm level on a conventional display screen, for example, to notify the signal level of the received radio wave, the alarm level is divided into, for example, five levels, and the area that is emitting light is increased (extended) by one for each level increase, taking the form of a level meter. However, by performing control to gradually change the emission color according to the alarm level, the alarm level can be expressed analogously, increasing the sense of luxury. The emission color may be changed, for example, from a blue system to a red system as the alarm level increases.

[0017] (3) The control means may change the emission intensity of the LED according to the alarm level. The change in emission intensity is realized, for example, by changing the lightness or luminance of the emission color. Such a change can change the luminance, for example, by using PWM for luminance, and the color and brightness of the LED can be set by other known methods (methods specified by the LED manufacturer). Also, the applied voltage of the LED may be adjusted to change the amount of light emission itself. Instead of changing the emission color as in the invention of (2), the same effect as above can be expected by changing the emission intensity. Also, the change in emission color and the change in emission intensity may be performed together. The emission intensity may be changed, for example, from a dark color to a bright color or the amount of light emission may be increased (made larger) as the alarm level increases.

[0018] (4) The alarm condition is radio wave reception, and the alarm level may be the signal level of the received radio wave. For example, when receiving a radio wave of a predetermined frequency that is an object of alarm, such as a microwave emitted from a speed measuring device, by changing the emission color and the intensity of the emission corresponding to the signal level of the received radio wave, it is possible to analogously represent the received signal level instead of an inorganic digital radar level meter.

[0019] (5) The alarm condition is that the current position and the object of alarm are in a proximity relationship, and the alarm level may be the degree of the proximity relationship. For the degree of the proximity relationship, for example, control is performed such that the alarm level increases as the distance decreases. By doing so, it is preferable because the approximate remaining distance to the object of alarm can be understood.

[0020] In addition to the radio wave reception in (4) and the proximity relationship in (5) described above, the alarm level includes various factors such as, for example, the degree of dangerous driving (the higher the sensor value of the acceleration sensor, the higher the degree of dangerous driving) and fuel consumption (such as a large fuel consumption per unit time and sudden acceleration).

[0021] (6) It is preferable to change the emission color by gradually changing the frequency of the emission color corresponding to the alarm level. By changing the frequency, the emission color can be continuously changed. In this case, it is good to perform smooth gradation control with the lower frequency corresponding to alarm level 1 and the higher frequency corresponding to the maximum alarm level.

[0022] (7) The control means has a function of giving an audible alarm when the alarm condition is satisfied, and the control means may change the light emission intensity of the LED according to the strength of the sound. When the alarm condition is satisfied, for example, when information about the object to be alarmed such as "There is a loop coil 1 km ahead. The speed limit is 60 km / h" or "The N system is just ahead" is announced audibly, it is preferable because the driver can know the content while facing forward or the like. In this case, by changing the light emission intensity (brightness, luminance, etc.) according to the strength (e.g., volume) of the pronunciation of the sound, the device itself will feel as if it is talking with intention, increasing the sense of luxury and also the interest. It is good to make the light emission intensity stronger (larger) as the sound is stronger (louder).

[0023] (8) The control means has a function of notifying information by a display screen, and the control means may control the light emission state of the light emitting part without changing the background color of the display screen when the alarm condition is satisfied. When the alarm condition is satisfied while various information is being output on the display screen, for example, if the background color of the display screen is changed to red or the like, the whole display screen will turn red, so it is possible to notify that there is an alarm. However, the originally provided information becomes difficult to see, which is not preferable. On the contrary, in the present invention, by changing the light emission state of the light emitting part without changing the background color of the display screen, it is possible to notify the driver of the existence of the object to be alarmed and at the same time, the information originally displayed and provided using the display screen will not become difficult to see, which is preferable.

[0024] (9) Based on the above invention of (8), the information may be map information. Map information, for example, displays roads in different colors. When the warning condition is satisfied, if the background color is set to a color similar to the color of the road, it becomes difficult to see the road. In particular, in the case of warning notification, the background color is often set to red for notification, and the color of the road, especially for arterial roads such as national highways, is also often displayed in red. Therefore, the two are likely to be of the same color system, and changing the background color causes the problem that it becomes difficult to confirm the arterial road. In contrast, in the present invention, since the background color of the display screen is not changed, it is preferable because the content of the map such as the road can be easily and accurately understood even during the warning (when the light emitting part is emitting light).

[0025] (10) Based on the above invention of (8) or (9), the control means may display warning information on the display screen when the warning condition is satisfied. By displaying warning information on the display screen, more specific and detailed content can be notified to the user. In this case, the presence of the warning target can be notified to the user by the light emission of the light emitting part provided separately from the display screen. That is, instead of having a plurality of information mixed in the same screen, the presence of the warning target is indicated by the display part provided outside the display screen, and the detailed content uses the display screen. Therefore, a user who only wants to know the presence of the warning target can achieve the purpose without looking at the display screen, and a user who wants to know the detailed content can also achieve the purpose by looking at the warning information displayed on the display screen.

[0026] (11) Based on the above invention of (10), the warning information is character information, and the color of the character information and the light emission color of the light emitting part may be of the same color system. Using character information makes it easier to understand the content. At this time, making the light emission color of the light emitting part and the color of the character information the same color system strengthens the association between the display part and the warning information (character information), and it is preferable because the user can easily find the position of the character information as the warning information displayed in the display screen.

[0027] (12) The alarm condition consists of a plurality of conditions, and the control means may be configured to make the light emission state when all of the plurality of conditions are satisfied different from the light emission state when a part of the plurality of conditions is satisfied. When some of the conditions are satisfied, there is a possibility that all of the conditions will be satisfied thereafter. Therefore, it is good to give the user a warning by giving a precursor warning when some of the conditions are satisfied. The light emission state when some of the conditions are satisfied should be less conspicuous and quieter than the light emission state when all of the conditions are satisfied.

[0028] For example, as the plurality of conditions, when "receiving a microwave (radio wave) of a predetermined frequency" (condition 1) and "the received signal level is equal to or higher than a reference value" (condition 2), when the two conditions are satisfied, it is assumed that radio waves emitted from the warning target are received, and a warning is given with a predetermined light emission state (for example, red light emission). When only condition 1 is satisfied (the signal level is less than the reference value), a warning is given with a different light emission state (for example, blue light emission). Even if the distance to the warning target is far and the received signal level is less than the reference value, it is quite common for the signal level to become equal to or higher than the reference value by further driving and approaching the warning target. In such a case, by giving a precursor warning in advance, the user can be mentally prepared and can drive safely without panicking even when a warning that satisfies all the conditions is issued.

[0029] (13) The light emitting part may be configured to emit one color as seen from the outside. Emitting one color as seen from the outside means that the light emitting color of the light emitting part visible from the outside only needs to be one color. Even if a plurality of light sources are built in, they are not made to emit light at the same time, or when they are made to emit light at the same time, they emit the same color so as to become one color. Also, for example, LEDs of different colors are arranged in proximity and the surface is covered with a cover such as white (semi-transparent). Then, one or a predetermined number of LEDs are made to emit light, and the light transmitted through the cover and emitted to the outside may be made to be one color of the combined color of the emitting LEDs. By making the light emitting color one, it is easy to understand what warning target the warning is about.

[0030] (14) The program of the present invention is a program for causing a computer to realize the function as the control means in the system according to any one of (1) to (13) above.

Effects of the Invention

[0031] According to the present invention, when the alarm condition is satisfied, the light emitting unit using the LED as a light source emits light in a predetermined light emitting color corresponding to the alarm target to give an alarm. Therefore, even if the user is not gazing at the light emitting unit, the user can recognize the presence or absence of such light emission and the light emission state (light emitting color), and can know the presence of the alarm target.

Modes for Carrying Out the Invention

[0033] 「Basic Configuration of Electronic Equipment」 FIGS. 1 and 2 show the configuration of a radar detector which is a preferred embodiment as an electronic device constituting the system of the present invention. The radar detector 1 includes a thin rectangular case body 2, and is attached and fixed to, for example, a dashboard of a vehicle using a bracket 3 attached to the lower part on the back side of the case body 2.

[0034] On the front surface of the case body 2 (the surface facing the rear of the vehicle (driver's side)), a display unit 5 is provided. The display unit 5 is composed of a 3.2-inch color TFT liquid crystal display. On this display unit 5, a touch panel 6 for detecting which part of the display unit 5 has been touched is provided. Also, a volume adjustment button 7 is arranged on the right side of the front surface of the case body 2, and various operation buttons 8 are arranged on the left side thereof.

[0035] On the right side surface of the case body 2, a card insertion slot 9 for mounting a memory card as a detachable recording medium is provided, and a memory card reader 10 is built inside the card insertion slot 9 in the case body 2. By inserting the memory card 11 through this card insertion slot 9, the memory card 11 is mounted on the memory card reader 10. The memory card reader 10 passes the data stored in the mounted memory card 11 to the control unit 18. More specifically, when there is update information such as new warning target information (position information such as longitude and latitude, type information, etc.) as the data stored in the memory card 11, the control unit 18 stores (downloads) the update information in the database 19, thereby updating the data.

[0036] The database 19 can be realized by a non-volatile memory (for example, EEPROM) built in the microcomputer of the control unit 18 or externally attached to the microcomputer. Note that map data and information regarding certain warning targets are registered in the database 19 at the time of shipment, and data such as data regarding warning targets added later is updated as described above.

[0037] A GPS receiver 13 is arranged inside the case body 2 above the center of the back side, and a microwave receiver 14 and a wireless receiver 15 are arranged beside it. The GPS receiver 13 receives GPS signals from GPS satellites and outputs current position (longitude and latitude) information. The microwave receiver 14 receives microwaves of a predetermined frequency emitted from a speed measuring device. The wireless receiver 15 receives wireless of a predetermined frequency flying in. A speaker 16 is also built inside the case body 2 below. The speaker opening is provided on the bottom surface of the case body 2.

[0038] A DC jack 17 is arranged at the lower part on the back side of the case body 2. This DC jack 17 is for connecting a cigar plug cord (not shown), and can be connected to the cigar socket of a vehicle via the cigar plug cord to receive power supply.

[0039] Further, the control unit 18 is a microcomputer including a CPU, a ROM, a RAM, a non-volatile memory, an I / O, etc., and is connected to the above-described respective units as shown in FIG. 2. Based on information input from the above-described various input devices (touch panel 6, GPS receiver 13, microwave receiver 14, wireless receiver 15, etc.), the control unit 18 executes predetermined processing and outputs predetermined alarms and messages using output devices (display unit 5, speaker 16, etc.). As these basic configurations, those similar to the conventional ones can basically be used.

[0040] The functions of the radar detector 1 of the present embodiment are stored on the EEPROM of the control unit 18 as programs executed by the computer included in the control unit 18, and are realized by the computer included in the control unit 18 executing these programs. The functions realized by the computer according to the program of the control unit 18 include a GPS logging function, a standby screen display function, a radar scope display function, a GPS alarm function, a radar wave alarm function, a wireless alarm function, and the like.

[0041] The GPS logging function is a function in which the control unit 18 associates the current position detected by the GPS receiver 8 every second with the detected time and speed (vehicle speed) and stores the result as a position history in a non-volatile memory. This position history is recorded in, for example, the NMEA format.

[0042] The standby screen display function is a function of displaying a predetermined standby screen on the display unit 5. FIG. 3(a) shows an example of the standby screen, which shows the speed, latitude, longitude, and altitude of the own vehicle detected by the GPS receiver 13.

[0043] As shown in Fig. 3(b), the MAP display function 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. Further, the MAP display function searches for warning targets around the current position based on the position information stored in the database 19, and when there is a warning target in the vicinity, it also has a function of superimposing and displaying information indicating the warning target (such as the target icon 112) at the corresponding position on the map. The specific display mode is as follows.

[0044] The control unit 18 displays a map in the main display area R1 that occupies almost the entire display unit 5 so that the traveling direction of the vehicle is always upward. The control unit 18 displays the map so that the center of the lower side of the main display area R1 is the current position of the host vehicle, and also displays the host vehicle icon 111 at that position.

[0045] The control unit 18 displays status information in the status area R2 set above the main display area R1. The status information displayed in the status area R2 is, in order from the left, the current time 121 (in the figure, "15:10"), the GPS radio wave reception level display icon 122 (in the figure, the maximum reception level with three straight lines of different lengths standing upright in parallel), the no-parking area icon 123 (displayed when in the most critical parking area or the critical parking area), the reception sensitivity mode display icon 124 indicating the reception sensitivity of the radar (in the figure, "SE" for the highest sensitivity), the vehicle speed 125 (in the figure, "30 km / h"), and the compass 126. The status area R2 is a transparent area and is arranged using a layer above the layer of the main display area R1. Thereby, even within the status area R2, the map located below can be visually recognized at locations where the status information is not displayed.

[0046] The control unit 18 displays the current scale information (scale) in the scale display area R3 set on the left side of the main display area R1. The scale sets the vehicle position as 0 m, and displays the distance from the vehicle position to the middle position in the vertical direction of the main area R1 ( "500" in the figure) and the distance to the upper position ( "1000" in the figure). The unit is "m". When the control unit 18 detects that the main display area R1 has been touched twice in a row, it displays a map scale change button at a predetermined position within the main display area R1 (a position corresponding to the scale display area R3) (not shown in the figure), and changes the map scale in response to a touch on the map scale change button. That is, the control unit 18 changes the scale of the map displayed in the main display area R1 according to the scale of the changed map scale, and also changes the scale information displayed in the scale display area R3.

[0047] During the execution of the standby screen display function as shown in Fig. 3(a), when the control unit 18 detects a single touch on the display unit 5, it displays a predetermined menu screen. When the control unit 18 detects that a screen switching button prepared in the menu screen has been touched, it switches to the MAP display function as shown in Fig. 3(b). Similarly, during the execution of the MAP display function, when the control unit 18 detects a single touch on the display unit 5, it displays a predetermined menu screen. When the control unit 18 detects that a screen switching button prepared in the menu screen has been touched, it performs a process of switching to the standby screen display function.

[0048] During the execution of the standby screen display function and the MAP display function (hereinafter these functions are collectively referred to as the standby functions), the control unit 18 executes processes to implement each function such as the GPS warning function, the radar wave warning function, and the wireless warning function according to the events that occur, and returns to the process of the original standby function when the process of the function ends. The priority of each function is set in descending order as the radar wave warning function, the wireless warning function, and the GPS warning function.

[0049] The GPS warning function is a process that is executed at a predetermined time interval (1-second interval) by an event from a timer in the control unit 18. It calculates the distance between the latitude and longitude of the warning target stored in the database 19 and the latitude and longitude of the current position detected by the GPS receiver 13. When the calculated distance reaches a predetermined approach distance, it displays a GPS warning display 130 (such as a schematic diagram of the warning target and the remaining distance) as shown in Fig. 4(a) on the display unit 5, and outputs an approaching warning voice indicating that fact from the speaker 16.

[0050] Such warning targets include drowsy driving accident locations, radars, speed limit switching points, enforcement areas, checkpoint areas, no-parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal violation suppression systems, police stations, accident-prone areas, areas with frequent carjacking, sharp / continuous curves (highways), branch / merge points (highways), ETC lane advance notice (highways), service areas (highways), parking areas (highways), highway oases (highways), smart interchanges (highways), within PA / SA gas stations (highways), tunnels (highways), highway radio reception areas (highways), prefectural boundary notifications, road stations, viewpoint parking lots, etc. The database 19 stores the type information of these warning targets, the latitude and longitude information indicating their positions, the data of the schematic diagrams or photos to be displayed on the display unit 5, and the voice data in association with each other.

[0051] Figure 4(b) shows an example display of the radar wave warning function. This radar wave warning function is an alarm function that, when a signal corresponding to microwave in a frequency band emitted from a speed measuring device (such as a mobile radar, hereinafter simply referred to as "radar") is detected by the microwave receiver 14, displays an alarm screen 131 on the display unit 5 and outputs an alarm sound from the speaker 20. For example, when microwaves in the frequency band of the microwaves emitted by the radar are detected by the microwave receiver 4, as shown in Figure 4(b), a schematic diagram or photo of the radar stored in the database 19 is displayed on the display unit 5 as an alarm screen, and the voice data stored in the database 19 is read out and a voice "There is a radar. Pay attention to speed" is output from the speaker 16.

[0052] The wireless warning function is a function that issues an alarm when the wireless receiver 15 receives radio waves emitted by an emergency vehicle or the like so as not to interfere with its running. In the wireless warning function, the frequencies of wireless signals used in 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, and when a wireless signal is received at the scanned frequency, a schematic diagram indicating that the wireless signal corresponding to that frequency stored in the database 19 for each wireless type is received is displayed on the display unit 5 as an alarm screen, and the voice data stored in the database 19 for each wireless type is read out and an alarm voice indicating the type of that wireless 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.

[0053] [Alarm Function Using Color LEDs] The following describes the alarm function using a color LED, which is a feature of the present invention. A light-emitting part 21 is provided at a predetermined position on the front surface of the case body 2. The installation position of this light-emitting part 21 is set at the center further above the display screen of the display part 5. Inside the case body 2 facing the light-emitting part 21, a color LED 22 is arranged. The color LED 22 is an RGB three-primary-color LED, that is, an LED incorporating chips of three primary colors. If R is 5 bits, G is 5 bits, and B is 5 bits, making a total of 15 bits, color control of 32,768 colors is performed. The light-emitting part 21 makes the emitted light color of the built-in color LED 22 visible from the outside, for example, by thinning the corresponding area of the front wall surface constituting the case body 2 or fitting a translucent member. Further, the light-emitting part 21 appears to emit one color when viewed from the outside.

[0054] The control part 18 controls the emission state of the color LED 22. That is, in the database 19, relationship information associating alarm targets and emission color information is stored and held. This relationship information is registered at the time of shipment as one of the information regarding the alarm targets. In the present embodiment, instead of associating emission color information for each individual alarm target, it is associated for each type of alarm target. That is, emission color information specifying the emission color to be displayed for each type, such as the fixedly installed speed measurement device (radar), N system, traffic monitoring point, checkpoint area, road station, etc., exemplified above as alarm targets in the GPS alarm function, is associated. Further, emission color information specifying the emission color corresponding to the speed measurement device (the alarm condition is signal detection corresponding to microwaves in a predetermined frequency band), which is an alarm target in the radar wave alarm function, and emission color information specifying the emission color corresponding to each radio type, which is a detection target in the wireless alarm function, are associated.

[0055] Figure 5 shows the functions of the control unit 18 that controls the light emission state of the light emitting unit 21 (color LED 22). When there is a warning target that satisfies the warning condition, the control of the light emission state of the light emitting unit 21 (color LED 22) in the control unit 18 causes the color LED 22 to emit light in the emission color corresponding to the warning target. When there are multiple warning targets that satisfy the warning condition, one of them is set as the warning target (target) to be notified, and the color LED 22 is caused to emit light in the emission color corresponding to the warning target that has become the target. Specifically, the control unit 18 executes the flowchart shown in Figure 5.

[0056] First, the control unit 18 determines whether or not a predetermined microwave has been received by the microwave receiver 14 (S1). When the control unit 18 has received a microwave (S1 is Yes), it accesses the database 19 and acquires the emission color information corresponding to the speed measuring device associated with the microwave reception recorded in the relationship information associating the warning target and the emission color information, and controls the color LED 22 to emit light in the emission color A specified by the emission color information. This emission color A is preferably a color such as red that indicates a high degree of urgency.

[0057] On the other hand, when the predetermined microwave has not been received (S1 is No), the control unit 18 determines whether or not a predetermined radio signal has been received by the radio receiver 15 (S3). When the control unit 18 has received a predetermined radio signal (S3 is Yes), it accesses the database 19 and acquires the emission color information corresponding to the radio type of the received radio signal recorded in the relationship information associating the warning target and the emission color information, and controls the color LED 22 to emit light in the emission color B specified by the emission color information. This emission color B actually varies depending on the radio type, and for example, an appropriate color is set according to the level of urgency of the radio type.

[0058] Also, depending on the radio type, a color such as red that indicates a high level of urgency is associated. In this case, it is preferable to use a color that is less urgent than the emission color associated with the speed measurement device associated with the above-described microwave reception. A color that indicates a low level of urgency may be, for example, a color with less redness or a color with reduced brightness and / or luminance.

[0059] On the other hand, when a predetermined radio signal is not received (S3 is No), the control unit 18 acquires the current position information detected by the GPS receiver 13 and determines whether there is a warning target in a predetermined proximity relationship around (S5). That is, the control unit 18 accesses the database 19 based on the acquired current position and determines whether there is a target warning target around the current position. The target warning target is within a fan-shaped area with a radius of X m (X is a reference distance) around the host vehicle (for example, within a predetermined angular range with respect to the traveling direction (for example, within an angle of 90 degrees or less to the left and right with respect to the traveling direction, particularly preferably 45 degrees or less).) When there is one warning target, that warning target becomes the target. When there are a plurality of warning targets, one that satisfies the conditions becomes the target. Such conditions are within a predetermined angular range with respect to the traveling direction and the closest one.

[0060] When the control unit 18 determines that there is a target warning target based on the position information (S5 is Yes), it accesses the database 19 and acquires the emission color information corresponding to the type of the target warning target recorded in the relationship information associating the warning target and the emission color information, and controls the color LED 22 to emit light in the emission color C specified by the emission color information. This emission color C actually varies depending on the type of the warning target. For those with a high level of importance such as a speed measurement device, it may be red. For those with a medium level of importance (giving attention) such as the N system, it may be blue. For those with a low level of demand (information provision level) such as a roadside station, it may be green, etc.

[0061] During driving, the driver needs to pay attention to the surrounding of the vehicle ahead and other vehicles. In this embodiment, when the warning condition is satisfied, the light emitting unit 21 emits light in a predetermined light emitting color corresponding to the warning target. Therefore, even if the radar detector (light emitting unit 21) is not within the field of view, the driver can know that it has emitted light, and can capture the light emitting unit 21 within the field of view by simply shifting the line of sight a little and confirm its light emitting color. As a result, it is possible to know that a warning target satisfying the warning condition exists in the surrounding, and what the warning target is. Since the warning using such a predetermined light emitting color uses the light emitting unit 21 having the color LED 22 as a light source, a large number of warning information is not notified, and since it is a simple warning of emitting light in a predetermined light emitting color, the driver can understand the warning content without staring at the light emitting unit for a long time, and can concentrate on information collection necessary for driving inside and outside the vehicle.

[0062] [Combined use of warning using display unit] As described above, when warning is performed by the color LED 22 (light emitting unit 21), warning by the display unit 5 may not be performed, or may be performed in combination. When used in combination, the warning target for displaying the target icon 112, GPS warning display 130, and warning screen 131 displayed on the display unit 5 for notification is the same as the warning target (target) for warning using a predetermined light emitting color by the color LED 22 (light emitting unit 21).

[0063] Then, when the warning condition is satisfied, the control unit 18 performs control to set a predetermined light emitting state without changing the background color of the display unit 5. Since the background color is not changed in this way, it is not difficult to see the map information etc. displayed on the display unit 5, and the notification of the information originally displayed on the display unit 5 and provided to the user can be performed as it is.

[0064] Furthermore, in the present embodiment, when the control unit 18 satisfies the warning conditions, it displays various warning information on the display unit 5, so that more specific and detailed content can be notified to the user. In this case, the user can be notified of the presence of the warning target by the light emission of the light emitting unit 21 provided separately from the display screen. That is, instead of a plurality of information being mixed in the same screen, the presence of the warning target is indicated by a display unit provided outside the display screen, and the detailed content uses the display screen. Therefore, a user who only wants to know the presence of the warning target can achieve the purpose from the light emission state of the light emitting unit 21 without looking at the display screen, and a user who wants to know the detailed content can also achieve the purpose by looking at the warning information displayed on the display screen.

[0065] Furthermore, when the control unit issues a warning using the display unit 5, it is preferable to use character information. In this case, the color of the character information and the light emission color of the light emitting unit 21 may be the same color system. By using character information, the content becomes easier to understand. At this time, by making the light emission color of the light emitting unit 21 and the color of the character information the same color system, the association between the light emitting unit 21 and the warning information (character information) is strengthened. Therefore, it is preferable because the user can easily find the position of the character information as the warning information displayed in the display unit 5.

[0066] [Another example of changing the light emission color by the warning target] In the above-described embodiment, the light emission color is changed according to the type of the warning target. However, the present invention is not limited to this. For example, in the case of a warning target based on position information, the light emission color may be set (associated) for each warning target for which the position information is registered. Alternatively, the warning targets may be divided into a plurality of groups according to the importance level (risk level), and the light emission color may be set for each group, and the warning targets belonging to the same group may have the same light emission color.

[0067] Also, in the above-described embodiment, in the case of using red for the light emission color B by the wireless warning function, the color is set to be less urgent than the red of the light emission color B by the radar wave warning function, but the same color may be used.

[0068] [Change of light emission state according to warning level] In the above-described embodiment, the control of the light emission state is performed to change the light emission color corresponding to the warning target. However, the present invention is not limited to this, and the light emission state may be changed according to the warning level. By using a color LED, a single LED can express a variety of colors. Therefore, it is possible to issue a warning in which the light emission color gradually changes by performing smooth gradation control from a low warning level to a high warning level. And the change of the light emission state according to the warning level may be, instead of the change of the light emission color as described above, or may be such that the light emission intensity of the color LED 22 is changed together with the change. The change of the light emission intensity is performed, for example, by the control unit 18 changing the lightness or luminance of the light emission color (for example, using PWM for luminance), or adjusting the applied voltage of the LED to change the light emission amount itself. When changing the light emission intensity, for example, it is preferable that as the warning level increases, the color changes from a dark color to a bright color, or the light emission amount becomes stronger (larger).

[0069] Regarding such a warning level, for example, when the warning condition is the reception of radio waves, it may be the signal level of the received radio waves. When receiving radio waves of a predetermined frequency that are a warning target, such as microwaves emitted from a speed measuring device, by changing the light emission color or the light emission intensity corresponding to the signal level of the received radio waves, the received signal level can be expressed analogously instead of an inorganic digital radar level meter.

[0070] Also, when the warning condition is that the current position and the warning target are in a proximity relationship, the warning level may be the degree of the proximity relationship. The control according to the degree of the proximity relationship is, for example, control in which the warning level increases as the distance approaches. By doing so, the approximate remaining distance to the warning target can be understood. That is, when performing the light emission of the light emission color C in FIG. 5, the control unit 18 performs control to change the light emission color based on the remaining distance to the warning target based on the light emission color based on the warning target.

[0071] Furthermore, in addition to the reception and proximity relationships of the predetermined radio waves described above, there are various factors for the warning level, such as the degree of dangerous driving and fuel consumption. For the degree of dangerous driving, for example, an acceleration sensor is provided, and the greater the sensor value of the acceleration sensor, the higher the degree of dangerous driving, that is, the warning level is set to be higher. Also, since fuel consumption deteriorates as the vehicle accelerates suddenly, based on the sensor value of the acceleration sensor, it is determined that the vehicle is driving with worse fuel consumption as the sensor value is larger. Further, it is advisable to obtain the fuel consumption based on the vehicle information provided by the vehicle. The OBD-II (II is the Roman numeral "2", hereinafter "OBD-II" will be referred to as "OBD2") connector installed in the vehicle is also called a fault diagnosis connector, is connected to the vehicle's ECU, and various vehicle information is output. Therefore, a connection cable for connecting to the OBD2 connector is attached to the case body to acquire vehicle information such as the MAF value (mass air flow), injection opening time, throttle opening, fuel flow rate, instantaneous fuel consumption, remaining fuel amount, and accelerator opening. The control unit 18 obtains the fuel consumption from, for example, the MAF value, or obtains the current fuel consumption based on the instantaneous fuel consumption output as vehicle information, etc.

[0072] On the other hand, regarding the change in the light emission state corresponding to the warning level, for example, the light emission color may be changed by gradually changing the frequency of the light emission color. By changing the frequency, the light emission color can be continuously changed. In this case, it is advisable to perform smooth gradation control with the lower frequency corresponding to warning level 1 and the higher frequency corresponding to the maximum warning level.

[0073] [Combined use with voice warning] The control unit is equipped with a function of issuing an audible alarm from the speaker 16 when an alarm condition is satisfied. And the control unit may change the emission intensity of the LED according to the strength of the voice. When the alarm condition is satisfied, for example, when information about an alarm target such as "There is a loop coil 1 km ahead. The speed limit is 60 kilometers per hour" or "The N system is just ahead" is announced audibly, it is preferable because the driver can know the content while facing forward or the like. In this case, by changing the emission intensity (brightness, luminance, etc.) according to the strength (for example, volume) of the voice pronunciation, it gives the feeling that the device itself is talking with intention, increasing the sense of luxury and also the interestingness. It is good to make the emission intensity stronger (larger) as the voice is stronger (louder).

[0074] [Alarm by composite conditions] The alarm condition may be a plurality of conditions (composite conditions). In this case, the control unit 18 may make the emission state when all of the plurality of conditions are satisfied different from the emission state when a part of the plurality of conditions is satisfied. When a part of the conditions is satisfied, there is a possibility that all the conditions will be satisfied later. Therefore, it is good to give the user a warning by giving a precursor alarm when a part of the conditions is satisfied. The emission state when a part of the conditions is satisfied should be less conspicuous and more subdued than the emission state when all the conditions are satisfied.

[0075] For example, as the plurality of conditions, when "receiving a microwave (radio wave) of a predetermined frequency" (condition 1) and "the received signal level is equal to or higher than a reference value" (condition 2), when both conditions are satisfied, an alarm is issued with a predetermined emission state (for example, red emission) assuming that radio waves emitted from the alarm target have been received, and when only condition 1 is satisfied (the signal level is less than the reference value), an alarm is issued with a different emission state (for example, blue emission). Even if the distance to the alarm target is far and the received signal level is less than the reference value, it often happens that the signal level becomes equal to or higher than the reference value by further traveling and approaching the alarm target. In such a case, by giving a precursor alarm in advance, the user can be prepared mentally and can drive safely without panicking even when an alarm that satisfies all the conditions is issued.

[0076] <Others> In the above-described embodiments, the case where the LED is color-controlled with a total of 15 bits with 5 bits for R, 5 bits for G, and 5 bits for B has been described. However, the number of bits is not limited to this, and it may be more or less. The more the number of bits for each color component increases, the greater the number of colors that can be color-controlled. For example, if the total is 24 bits with 8 bits for R, 8 bits for G, and 8 bits for B, color control of 16,777,216 colors becomes possible.

[0077] In the above-described embodiments, the display unit 5 is provided and a map is displayed on the display unit 5. However, it may not display a map, or there may be no display unit at all.

[0078] Also, the color LED 22 is built into the case body 11, but the present invention is not limited to this, and the color LED 22 may be exposed to the outside. Also, the number of installed color LEDs is arbitrary. The main point is that when viewed from the outside, the light-emitting part 21 should appear to emit one color.

[0079] Furthermore, in the embodiment, the position of the light-emitting part 21 is set to the central part further above the display screen of the display unit 5. However, it is not limited to this, and it may be set to a position biased to either the left or right above the outside of the display screen, or it may be outside the display screen, either horizontally or below it.

[0080] Also, although the light-emitting part 21 is shown as a rectangular region in FIG. 1, its shape is arbitrary and can take various shapes such as an ellipse, a circle, etc. Also, as shown in FIG. 6, the light-emitting part 21 may be a predetermined character (string), symbol, mark, etc. FIG. 6 shows an example in which the light-emitting part 21 is provided on the left side of the display screen 5, and further shows an example in which the light-emitting part 21 is composed of a trademark manufacturer name or other logo. Then, a color LED 22 is arranged on the back side (inside the case body 2) of the light-emitting part 21 composed of this logo. In this example, only the logo part emits light in various colors according to the situation. This is, for example, by forming the case body 2 from a material such as plastic in black or the like that does not transmit light, and providing slits or holes that penetrate inside and outside in the logo part. Then, a closing member made of a material (transparent or translucent plastic, etc.) through which light passes is fitted into and closes such holes. Thereby, while suppressing dust, dirt, etc. from entering the case body 2 through the holes, the light from the color LED 22 passes through the closing member and reaches the outside. Therefore, when viewed from the outside, the user can see that the closing member, that is, the logo part, is emitting light.

[0081] Here, only the part such as the logo emits light, but the entire peripheral region including the logo etc. may be made to emit light. This is, for example, by printing a logo etc. on the rectangular light-emitting part 21 shown in FIG. 1. Thereby, the entire rectangular region that is the light-emitting part 21 emits light in various colors according to the situation, and the logo appears to stand out and be visible due to the light.

[0082] Figures 7 and 8 show an example of the correspondence between the types of alarm targets and the colors (the emission colors of the LEDs) associated therewith. As shown in the figures, the alarm targets associated with the emission colors of the LEDs are, as broadly classified genres, radar (corresponding to the "radar wave alarm function" of the embodiment), radio (corresponding to the "radio alarm function" of the embodiment), GPS (corresponding to the "GPS alarm function" of the embodiment), and the system. The system is all others that do not fall under any of radar, radio, and GPS, and the emission color is white. Therefore, when the light emission is made to be linked with the sound, the control unit 18 performs control to emit the color LED in white when outputting all other sounds that do not fall under the three genres.

[0083] Also, as specific alarm targets belonging to the genre of radar, there are a normal alarm when a predetermined microwave is received and a stealth alarm when a stealth wave having a characteristic of emitting a strong radio wave instantaneously is detected. And the normal alarm alarms with color-coding in five levels according to the reception level (the signal strength of the received signal). The one with the smallest reception level is "Normal Alarm Level 1" and the emission color is "yellow-green". In order of increasing reception level hereinafter, the emission color of "Normal Alarm Level 2" is "yellow", the emission color of "Normal Alarm Level 3" is "light orange", the emission color of "Normal Alarm Level 4" is "orange", and the emission color of "Normal Alarm Level 5" is "red" are associated. Thus, when at level 1 with a small reception level, a color with a relatively safe image such as the green system (yellow-green) is used, and when the level rises a little (level 2), it is set to "yellow" by prompting attention. And from level 3 onwards, colors with an image representing danger and alarm in the red system are used to alarm the user. Further, for the stealth alarm, control is performed to gradually change the emission color from the blue system to the red system and then gradually change the emission color towards the blue system.

[0084] The relationship between the specific types of warning targets (warning items) and the emission colors in the wireless genre is defined as follows: "Regulatory Wireless: Pink", "Car Karaoke Proximity: Pink", "Car Karaoke Distance: Yellow", "Digital Wireless: Yellow", "Outside the Car Karaoke Range: Aqua", "Ultra-Small Wireless: Aqua", "Police Activity Wireless: Aqua", "Police Wireless: Aqua", "Lecca Wireless: Aqua", "Helitere Wireless: Yellow-Green", "Fire Department Helitere Wireless: Yellow-Green", "Fire Department Wireless: Yellow-Green", "Emergency Wireless: Yellow-Green", "Highway Wireless: Yellow-Green", "Security Wireless: Yellow-Green".

[0085] The relationship between the specific types of warning targets (warning items) and the emission colors in the GPS genre is defined as follows: "Orbis: Red", "Speed Exceeded: Red", "Speed Limit Switch: Yellow", "Regulatory Area: Yellow", "Checkpoint Area: Yellow", "Most Restricted Parking Area: Yellow", "Restricted Parking Area: Yellow", "Highway Traffic Police: Yellow", "Intersection Monitoring Point: Yellow", "Signal Ignoring Suppression System: Yellow", "My Area: Yellow", "N System: Blue", "Traffic Monitoring System: Blue", "Police Station: Blue", "Accident-Prone Area: Blue", "Areas with Many Carjacking Incidents: Blue", "Highway Sharp / Continuous Curves: Blue", "Highway Merge / Branch Points: Blue", "ETC Lane: Green", "Service Area: Green", "Parking Area: Green", "Highway Oasis: Green", "Long / Continuous Highway Tunnels: Green", "Highway Radio Reception Area: Green", "Prefectural Border: Green", "Roadside Station: Green", "Viewpoint Parking: Green".

[0086] In the above embodiment, the Eve radar detector was used as an example for explanation because it is fixedly installed by pasting or the like at a predetermined position inside the vehicle such as a dashboard using bracket 3 as an application device of the system of the present invention. However, it can also be applied to a mirror-type radar detector attached to the rearview mirror. Furthermore, the present invention is not limited to a radar detector and can be implemented as a function of various in-vehicle electronic devices. For example, it may be incorporated as a function of a navigation device or the like.

[0087] In the above-described embodiments and modifications, the apparatus includes a database 19 that stores various types of information, and the control unit 18 accesses the database 19 to read necessary information and performs various processes. However, the present invention is not limited to this. That is, part or all of the information registered in the database 19 may be registered in a server. Then, the radar detector and other electronic devices and apparatuses may be configured to communicate with the server, and the control unit 18 may access the server as appropriate to acquire necessary information and execute processes. A part or all of the control unit may be implemented in the server, and a part of the processes may be executed on the server side and the in-vehicle device side may acquire the results and perform predetermined displays. Further, the display device may use a device mounted on another in-vehicle device or a vehicle.

[0088] In the embodiments and the like, a GPS receiver for detecting current position information is incorporated. However, in the present invention, a configuration including a GPS receiver is not essential, and current position information may be acquired from a vehicle or other in-vehicle devices, and based on the acquired information, it may be possible to determine the presence or absence of a proximity relationship with an alarm target.
