Summary of the Invention

Problems to be Solved by the Invention

[0004] Conventional radar detectors and the like have various problems that have not been solved. One of the objects of the present invention is to provide a technology for solving the problems of conventional systems and the like.

[0005] The above-described problems are described as independent ones, and the present invention does not necessarily have to solve all of the described problems. The object of the invention of the present application is not limited to this, and the applicant also has the intention of obtaining rights by means of divisional application, amendment, etc. for a configuration aimed at obtaining an effect resulting from a part of the configuration disclosed in this specification, drawings, etc. For example, a problem in which a part described as "can be" in this specification is read as "is a problem" is disclosed in this specification. The problems are described as independent ones, and the applicant also has the intention of obtaining rights by means of divisional application, amendment, etc. alone for a configuration for solving this problem. Even if a problem is implicitly grasped from the description of the specification, the applicant has the intention of making 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 Problems

[0006] (1) A receiving unit provided in a vehicle for receiving a predetermined microwave in a predetermined frequency band that can be used by a vehicle speed measuring device, and a control unit that performs a predetermined process in response to the reception of the predetermined microwave, wherein the receiving unit receives, as the predetermined microwave, a microwave in a predetermined frequency band belonging to the K band that can be used in a vehicle speed measuring device, and the control unit has a function of recognizing whether the predetermined microwave received by the receiving unit is a predetermined microwave output from a specific vehicle speed measuring device that uses the K band, and a system that performs different processes according to the recognition result is preferably provided.

[0007] In this way, the control unit can perform different processes depending on whether it recognizes the reception of a microwave output from a specific vehicle speed measuring device that uses the K band or not.

[0008] (2) The control unit may recognize the specific vehicle speed measuring device when the predetermined microwave is a modulated wave.

[0009] By doing so, the control unit can determine whether it has received microwaves from a specific vehicle speed measuring device based on whether the received microwaves are modulated waves. The control unit can detect a vehicle speed measuring device that uses modulated waves in the K band.

[0010] (3) It has a non-volatile storage means for storing information for specifying a cancellation area for suppressing the notification of a reception warning based on the reception of the microwaves. The control unit performs a process of registering information for specifying the cancellation area in the storage means based on the reception of a predetermined microwave. When a predetermined microwave from the specific vehicle speed measuring device is received within a predetermined moving range after the reception, a process of deleting the information for specifying the cancellation area registered in the storage means may be performed.

[0011] By doing so, even if information for specifying a cancellation area is once registered in the storage means based on the reception of microwaves, the registered information can be deleted when microwaves from a specific vehicle speed measuring device are received. As a result, when microwaves from a specific vehicle speed measuring device are received, they are not registered in the cancellation area. Therefore, when traveling through the same location next and microwaves are received, they are not cancelled and are notified.

[0012] (4) The control unit stores information for specifying the cancellation area in a volatile memory based on the reception of a predetermined microwave. After storing in the memory, when the registration prohibition condition is not satisfied during traveling a predetermined distance, a process of registering the information for specifying the cancellation area stored in the memory in the storage means is performed. When the registration prohibition condition is satisfied during the predetermined distance traveling, it is preferable not to register the information for specifying the cancellation area in the storage means.

[0013] By doing so, when the microwave is received, the control unit temporarily stores the information for identifying the cancellation area in the volatile memory. Therefore, for example, when the cancellation area and the registration prohibition condition are satisfied immediately after receiving the microwave, it is not necessary to register it in the non-volatile storage means. Therefore, the operation of deleting it after registering once as in (3) becomes unnecessary.

[0014] (5) When the control unit receives a predetermined microwave from the specific vehicle speed measuring device during traveling, it may perform a process of deleting the information for identifying the cancellation area from the storage means.

[0015] By doing so, even when the cancellation area is set in accordance with the reception of the predetermined microwave, if the microwave from the specific vehicle speed measuring device is received thereafter, the cancellation area can be deleted. Therefore, when traveling at the same location after the deletion, when the microwave of the specific vehicle speed measuring device is received, the control unit can output a reception warning based on the reception of the microwave without cancellation.

[0016] (6) When the control unit receives a predetermined microwave from the specific vehicle speed measuring device, it may perform a process of deleting the information for identifying the cancellation area set around the received position from the storage means.

[0017] By doing so, the cancellation area set around the position where the microwave from the specific vehicle speed measuring device is received can be deleted. Therefore, when traveling at the same location next time, it is possible to issue a reception warning based on the reception of the microwave even in a wider range with respect to the specific vehicle speed measuring device. Also, the user can know earlier that there may be a specific vehicle speed measuring device.

[0018] (7) The information for specifying the cancellation area is position information indicating the center point of the cancellation area, and the control unit may delete the position information indicating the center point existing within an area having a length corresponding to the receivable distance of the radar wave of the specific vehicle speed device, centered on the received position.

[0019] By doing so, the cancellation range is not set in the area where microwaves from a specific vehicle speed measurement device can be received, and the control unit can issue a reception warning based on the reception of microwaves from a farther position. As a result, the user can know earlier that there may be a specific vehicle speed measurement device.

[0020] (8) When the control unit receives microwaves from a vehicle speed measurement device in the X band, it is preferable not to perform the process of deleting the information for specifying the cancellation area from the storage means.

[0021] By doing so, it is different from the process at the time of receiving a specific vehicle speed measurement device in the K band. When microwaves from a vehicle speed measurement device in the X band are received, the setting of the cancellation area is not deleted and remains as it is. Therefore, when driving the same place next time, the reception warning based on the reception of microwaves can be suppressed, and the possibility of false alarms can be suppressed.

[0022] (9) When the control unit recognizes the reception of microwaves from the specific vehicle speed measurement device while driving in the cancellation area, it is preferable to issue an alarm for the specific vehicle speed measurement device and delete the information for specifying the cancellation area.

[0023] By doing so, even when driving in the cancellation area, the presence of a specific vehicle speed measurement device can be alerted and notified to the user. Also, the control unit can delete the information for specifying the cancellation area. And by this deletion, when driving the same place after the next time, the control unit can issue a reception warning based on the reception of microwaves from a specific vehicle speed measurement device.

[0024] (10) It has a storage means for storing the deployment information on whether or not the specific vehicle speed measuring device is deployed for each predetermined area, and when the control unit receives a microwave in the K band at the current position in the first area where the specific vehicle speed measuring device is deployed, it may notify before being identified as the specific vehicle speed measuring device.

[0025] In this way, even in a situation where the received microwave cannot be recognized as being from a specific vehicle speed measuring device, it is possible to give a notification accompanying the reception of the microwave. Since the first area is an area where a specific vehicle speed measuring device is deployed, the received microwave may be from the specific vehicle speed measuring device, so that a notification can be given earlier.

[0026] (11) After the control unit gives a notification based on the reception of the microwave in the K band, if it is recognized that it is not the specific vehicle speed measuring device, it may notify that it is not the specific vehicle speed measuring device.

[0027] In this way, the control unit can notify that the notification made based on the reception is not based on the reception of the specific vehicle speed measuring device. The user can know from this notification that the specific vehicle speed measuring device does not exist in the surroundings. The notification that it is not based on the reception of the specific vehicle speed measuring device may, for example, directly notify that the specific vehicle speed measuring device does not exist, or notify that it is based on a false alarm source, for example.

[0028] (12) In the second area where the specific vehicle speed measuring device is not deployed at the current position, the control unit may suppress a reception alarm based on the reception of a microwave in the K band.

[0029] By doing so, when the control unit receives microwaves in the K band, it can suppress the reception alarm based on the reception of the microwaves. Since the second region is not equipped with a specific vehicle speed measurement device, when microwaves in the K band are received, they are from a device other than the specific vehicle speed measurement device. Therefore, by suppressing the reception alarm, the possibility of false alarms can be suppressed as much as possible.

[0030] (13) The control unit may perform a process of not sounding an alarm sound as the suppression of the reception alarm.

[0031] By doing so, when the control unit receives microwaves in the K band, it does not need to output an alarm sound. The alarm sound is one of the alarms that can be recognized aurally even when the user is not looking at the system side. By not outputting the alarm sound, it is difficult to recognize that there has been an alarm if the user is not concentrating on the system, so it is preferable as a suppression of false alarms.

[0032] (14) The control unit may acquire the deployment information distributed together with the update data of the public security information and perform an update process of the deployment information stored in the storage means.

[0033] By doing so, the control unit can update the deployment information at an appropriate timing. Since the public security information is update data that is distributed periodically, by distributing it together, the deployment information held in memory by the system will also be up-to-date.

[0034] (15) The storage means stores the operation setting conditions when receiving microwaves, including the first setting conditions for the first region where the specific vehicle speed measurement device is deployed and the second setting conditions for the second region where the specific vehicle speed measurement device is not deployed. The control unit may perform the microwave reception process under the first setting conditions when the current position is in the first region, and perform the microwave reception process under the second setting conditions when the current position is in the second region.

[0035] By doing so, in the area where a specific vehicle speed measuring device is installed and the area where it is not installed, the control unit can perform pre-processing of microwaves under appropriate operation setting conditions respectively. The switching of these operation setting conditions is automatically performed based on the current position and the deployment status of the specific vehicle speed measuring device for each area stored and held. Therefore, the user can use the system without being aware of whether the specific vehicle speed measuring device is deployed in the current area.

[0036] (16) It is provided with reception means for receiving an instruction from the user, and the control may operate in either a mode of switching the operation setting conditions based on the current position according to the instruction from the reception means or a mode of not performing the switching.

[0037] By doing so, based on the user's instruction, it is possible to switch between automatically performing and not performing the switching of the operation setting conditions according to the deployment status of the specific vehicle speed measuring device. Thereby, an operation according to the user's preference is ensured.

[0038] (17) The specific vehicle speed measuring device outputs a modulated wave of the K band. When the control unit cannot recognize that the received microwave is the modulated wave of the K band, it notifies a reception warning. When the modulated wave of the K band is recognized during the notification of the reception warning, it switches to a warning for notifying the specific vehicle speed measuring device. When the received microwave is unmodulated, it is preferable to notify that the reception warning is based on a false alarm source.

[0039] In this way, when the control unit receives the microwave in the K band, it can issue a reception warning. As a result, the user can be informed earlier of the possibility that a specific vehicle speed measuring device exists. Further, when the control unit recognizes a modulated wave in the K band, it outputs a warning to notify the specific vehicle speed measuring device. As a result, the user can understand that the previously issued reception warning is based on the reception of the radar wave from the specific vehicle speed measuring device. Further, when the control unit recognizes that the received microwave is unmodulated, it notifies that the reception warning is based on a malfunction source. As a result, the user can know that the previously issued reception warning is from a false alarm source and can understand that there is no specific vehicle speed measuring device around.

[0040] (18) The specific vehicle speed measuring device outputs a modulated wave in the K band. When the control unit recognizes that the received microwave is the modulated wave in the K band, it outputs a warning to notify the specific vehicle speed measuring device. When the received microwave cannot be recognized as the modulated wave in the K band, it has a first mode of notifying a reception warning and a second mode of not notifying the reception warning, and is provided with reception means for receiving an instruction from the user. The control unit may operate in the first mode or the second mode according to an instruction from the reception means.

[0041] In this way, according to an instruction from the user, the control unit can operate by switching the presence or absence of notification when receiving a microwave in the K band that cannot recognize the modulated wave. The user can perform an operation according to his or her preference to give or not give a reception warning in a state where the specific vehicle speed measuring device cannot be recognized.

[0042] (19) The specific vehicle speed measuring device outputs a modulated wave in the K band and is provided with a false alarm reduction switch. When the false alarm reduction switch is ON, the control unit may suppress the warning until the received microwave is recognized as the modulated wave in the K band and output a warning when it is recognized as the modulated wave in the K band.

[0043] In this way, when the false alarm reduction switch is ON, the control unit performs control to suppress the alarm. Thereby, the occurrence of false alarms can be suppressed.

[0044] (20) The control unit may notify different alarm sounds depending on whether the received microwave is a modulated wave or an unmodulated wave in the K band.

[0045] In this way, the control unit can notify different alarm sounds depending on whether the received K-band microwave is a modulated wave or an unmodulated wave. Even if the user is not watching the system, the user can visually distinguish whether it is a modulated wave, that is, a specific vehicle speed measurement device, or an unmodulated wave, that is, not a specific vehicle speed measurement device, from the difference in the alarm sound.

[0046] (21) The program of the present invention causes a computer to realize a function of performing predetermined processing in response to reception of a predetermined microwave in a predetermined frequency band that is provided in a vehicle and can be used by a vehicle speed measurement device, and the receiving unit is configured to receive, as the predetermined microwave, a microwave in a frequency band belonging to the K band that can be used in the vehicle speed measurement device, and the predetermined processing is preferably a program that varies depending on the recognition result of whether the predetermined microwave received by the receiving unit is a predetermined microwave output from a specific vehicle speed measurement device that uses the K band.

[0047] (22) A program for causing a computer to realize the function of the control unit used in the system according to any one of the above may be provided.

[0048] (23) The function of the receiving unit may be realized mainly by hardware elements, but if some or all of the functions are realized by software elements, the hardware configuration of the system can be simplified.

[0049] The invention of the present application may be understood as follows.

[0050] (A) An antenna that receives microwaves (an antenna substrate having a patch antenna), a processing unit that processes the microwaves received by the antenna, and a housing that houses the antenna and the processing unit, wherein the distance between the patch antenna and the inner surface of the housing facing the patch antenna is set to a length corresponding to the frequency of the microwaves.

[0051] In this way, the gap is set to a length corresponding to the frequency of the microwaves. By making the corresponding length appropriate, the reception sensitivity of the microwaves can be improved. The length corresponding to the frequency may be, for example, 1 / 2λ or its multiples, and may also be 1 / 4λ or the like.

[0052] (B) The microwaves are preferably microwaves emitted from a vehicle speed measuring device that uses the K band.

[0053] In this way, an improvement in the reception sensitivity of the microwaves emitted from a vehicle speed measuring device that uses the K band can be expected.

[0054] (C) The housing preferably has a portion facing the antenna protruding outward and a concave portion formed on the inner surface.

[0055] In this way, the distance of the gap can be ensured to be longer by the depth of the concave portion compared to the region where the concave portion is not formed. The region where the concave portion is not formed has a small protrusion amount and can be made thinner and smaller.

[0056] (D) The antenna has a first patch antenna that receives a first frequency band and a second patch antenna that receives a second frequency different from the first frequency. The width of the arrangement region of the second patch antenna is wider than the width of the arrangement region of the first patch antenna, and the planar shape of the concave portion is preferably a trapezoid with a longer length of the side facing the second patch antenna side.

[0057] By doing so, while efficiently accommodating the first patch antenna and the second patch antenna in the formation region of the recess that protrudes outward, other parts can be brought closer to the components and substrates housed in the housing to achieve thinning.

[0058] (E) The second patch antenna is for receiving in the K band, and the length corresponding to the frequency of the microwave is preferably set to the length corresponding to the frequency of the microwave in the K band.

[0059] By doing so, the reception sensitivity of the microwave in the K band can be increased. Compared with the vehicle speed measurement device using the X band, the radar wave emitted from the vehicle speed measurement device using the K band has a smaller radio wave intensity and a smaller reception level in the system. Therefore, the reception sensitivity of the K band with a small reception level can be increased, and the radar wave from the vehicle speed measurement device using the microwave in the K band can be received from a farther distance.

[0060] (F) On the premise of the configuration of (E), the gap is preferably set to a length corresponding to the frequency at least for the portion facing the second patch antenna.

[0061] By doing so, while increasing the reception sensitivity of the microwave in the K band, other parts can be set at their respective original positions.

[0062] (G) The housing contains components whose performance is affected by the distance from the inner surface of the housing, and it is preferable to arrange such components so as to face other than the recess.

[0063] By doing so, it is possible to directly use the components designed conventionally according to a housing without a recess protruding outward.

[0064] (H) The component is preferably at least one of a GPS antenna and a laser light receiving unit.

[0065] By doing so, the GPS antenna and the laser light receiving unit can use the conventionally used design values.

[0066] The inventions described in the above (1) to (23) can be arbitrarily combined. For example, it may be configured to add at least a part of the configuration of at least one of the inventions after (2) to all or a part of the configuration of the invention described in (1). In particular, it is preferable that the invention is obtained by adding at least a part of the configuration of at least one of the inventions after (2) to the invention described in (1). Further, any configuration may be extracted from the inventions described in (1) to (23), and the extracted configurations may be combined. Also, the inventions described in the above (A) to (H) can be arbitrarily combined. For example, any configuration may be extracted from the inventions described in (A) to (H), and the extracted configurations may be combined. Furthermore, all or part of the configurations of the inventions described in these (A) to (H) and all or part of the configurations of the inventions described in (1) to (23) may be combined. The applicant of the present application intends to obtain rights for inventions including these configurations. Also, even if there is a description such as "in the case of ~" or "when ~", it is not described as a configuration limited to that case or that time. These show examples of better configurations, and the applicant also intends to obtain rights for configurations other than these cases and times. Also, the parts described in an order are not limited to this order. The disclosure also includes configurations in which some parts are deleted or the order is changed, and the applicant intends to obtain rights for such configurations.

Mode for Carrying Out the Invention

[0068] Hereinafter, embodiments of the present invention will be described with reference to the drawings. These drawings are used to explain the technical features that the present invention can adopt. 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, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention. In the following description, the labeling using numerical values such as first, second, ··· is for identifying each element and does not define the number of elements. The following embodiments are examples of embodiments for solving such problems.

[0069] The embodiments of the present application are conceived by the inventor of the present application in order to solve at least any of the above problems.

[0070] [A. First Embodiment]

[0071] [2. Configuration of Electronic Device 10] FIG. 1 is a diagram for explaining an overview of an electronic device 10 according to a first embodiment of the present invention. The electronic device 10 is an electronic device disposed in a vehicle 40 and provides various types of information to a driver or other users. The electronic device 10 has a function of a radar / laser detector and provides information useful for the safe driving of the driver. The vehicle 40 is preferably a four-wheeled automobile, but is not limited to a four-wheeled automobile, and may be, for example, a two-wheeled vehicle such as a motorcycle or a large transport vehicle having four or more wheels.

[0072] The electronic device 10 has a notification function for notifying a user when the vehicle 40 has a predetermined proximity relationship with a predetermined target. The predetermined proximity relationship means a relationship in which the vehicle 40 is approaching a target up to a predetermined distance or less, and further, a relationship in which a target exists in the traveling direction or the path of the vehicle 40 and is approaching the target up to a predetermined distance or less. As the target, for example, there is a speed limit location where vehicle speed enforcement is performed. A vehicle speed measuring device may be installed at the speed limit location. The electronic device 10 receives an enforcement wave emitted from the vehicle speed measuring device. The enforcement wave is an electromagnetic wave for measuring the speed of the vehicle and may be referred to as a measurement wave, a speed measurement signal, or the like. The speed limit location is determined in consideration of situations such as the traveling situation of the vehicle (for example, the vehicle is likely to gain speed) and the occurrence situation of traffic accidents (for example, a location where the number of accidents is large). An example of the speed limit location exists, for example, on a general road, a straight road, a curve, or a location ahead of a curve in a route (road) on which the vehicle travels. There are many vehicle speed measuring devices, such as those called fixed type and mobile type. The mobile type includes, for example, a portable type and a type mounted on a vehicle.

[0073] The electronic device 10 is roughly divided into a main body portion 101 and a fixing portion 102. The main body portion 101 is fixed to a predetermined installation position using the fixing portion 102. In the present embodiment, the installation position is the upper surface of the dashboard 41 of the vehicle 40. The fixing portion 102 is provided under the main body portion 101 and is a fixing member for fixing the main body portion 101 to a predetermined installation position. The fixing portion 102 is also called a bracket.

[0074] FIG. 2 is a diagram showing the external configuration of the main body 101. FIG. 2(A) is a view of the main body 101 as seen from the upper right obliquely forward. FIG. 2(B) is a view of the main body 101 as seen from the upper left obliquely backward.

[0075] The main body 101 has a housing 1011. The housing 1011 is in the shape of a rectangular parallelepiped that is longer in the left-right direction than in the up-down direction and has a relatively small thickness. The housing 1011 is formed of, for example, resin or other materials. On the front side of the housing 1011, a rectangular opening that is longer in the left-right direction than in the up-down direction is provided. The main body 101 has a display unit 13 for displaying an image at the position of this opening, and a touch sensor 191 superimposed on the display area of the display unit 13. The main body 101 has an illuminance sensor window 201 and a light emitting unit 24 at a position on the left side of the display unit 13 on the front side thereof. The light emitting unit 24 has a light emitting area with the longitudinal direction in the up-down direction. A memory media insertion port is provided on the right side surface of the housing 1011. Through this memory media insertion port, a memory media 50 is attached to the main body 101. The memory media 50 is, for example, an SD card. The SD card includes any of the shapes such as an SD memory card, a miniSD card, and a microSD card.

[0076] A lens holder 1012 is provided on the back side of the housing 1011. The lens holder 1012 is a through hole that penetrates the inside and outside of the housing 1011 and holds a lens 121. The lens 121 is a condensing lens. In the present embodiment, the lens 121 is an aspherical lens (esferic lens) that is in an elliptical shape that is longer in the left-right direction than in the up-down direction and has an aspherical light incident surface, but other condensing lenses may be used. In the vicinity of the lower end on the back side of the housing 1011 and near the center in the left-right direction of the housing 1011, a mounting portion 1013 is provided. The mounting portion 1013 is a portion to which a fixing portion 102 is attached. The mounting portion 1013 has a pair of groove portions each extending vertically. On the back side of the housing 1011, further, a power switch 221 for switching on / off the power of the electronic device 10 and a terminal portion 23 for connecting an external device are provided.

[0077] FIG. 3 is a diagram showing the external configuration of the fixing part 102. FIG. 3(A) is a view of the fixing part 102 seen from the upper right diagonal direction on the front side. FIG. 3(B) is a view of the fixing part 102 seen from the upper left diagonal direction on the front side.

[0078] The fixing part 102 is a member fixed to the installation position using the fixing member 1021 and has a pedestal part 1022, a socket part 1023, a ball stud 1024, and a mounting member 1025. The pedestal part 1022 is a part fixed to the installation position (installation surface). The bottom surface of the pedestal part 1022 is attached to the installation position using a fixing member 1021 such as an adhesive sheet or double-sided tape. The pedestal part 1022 has a socket part 1023 having a space opened on the front side. The socket part 1023 has a ball part of the ball stud 1024 mounted thereon. The socket part 1023 and the ball stud 1024 mounted on the socket part 1023 constitute a ball joint mechanism. The ball stud 1024 changes its posture up and down and left and right in a state of being mounted on the socket part 1023 when receiving an external force. A mounting member 1025 is provided at the front part of the ball stud 1024. The mounting member 1025 is mounted on the mounting part 1013 of the main body part 101. The mounting member 1025 has a pair of protruding parts protruding to the front side on both the left and right sides when viewed from the front.

[0092] The terminal unit 23 may be connected to an OBDII adapter that can be connected to the OBDII (where "II" is the Roman numeral for "2") connector of the vehicle 40. The OBDII connector, also called a fault diagnosis connector, is a terminal connected to the vehicle's ECU (Engine Control Unit) and outputs various vehicle information at predetermined intervals (for example, every 0.5 seconds). When the terminal unit 23 is connected to the OBDII connector using the OBDII adapter, the electronic device 10 can receive the supply of operating power and acquire vehicle information.

[0093] The vehicle information is information regarding the state of the vehicle 40. The vehicle information includes, for example, the speed (vehicle speed) of the vehicle 40, engine speed, engine load ratio, throttle degree, ignition timing, ratio of remaining fuel, pressure in the intake manifold, intake air volume (MAF), injection opening time, temperature of the engine cooling water (cooling water temperature), temperature of the air intake to the engine (intake air temperature), outside air temperature, amount of remaining fuel in the fuel tank (remaining fuel amount), fuel flow rate, instantaneous fuel consumption, accelerator opening degree, wiper information (operation (ON / OFF) of the left and right wipers), brake opening degree, rotational steering angle of the steering wheel, gear position, and information on the door open / closed state, etc. and at least one or more of these may be included.

The storage unit 25 further stores map data indicating a map, the type and position information of a target object, data for notifying the presence of the target object (for example, audio data such as sound effects, BGM, and voice messages, image data such as photos and schematic diagrams, etc.), data for realizing a route guidance function when the electronic device 10 has a navigation function, data for displaying a standby screen, and the like. The target object is, for example, in addition to a vehicle speed measuring device (laser type, radar type, loop coil type, H system, LH system, photoelectric tube type, mobile type, etc.), a drowsy driving accident location, a speed limit switching point, a regulated area, a checkpoint area, a no-parking monitoring area, an N system, a traffic monitoring system, an intersection monitoring point, a signal violation suppression system, a police station, an accident-prone area, a vehicle theft-prone area, a sharp / continuous curve (highway), a branch / merge point (highway), ETC lane advance notice (highway), a service area (highway), a parking area (highway), a highway oasis (highway), a smart interchange (highway), a gas station inside a PA / SA (highway), a tunnel (highway), a highway radio reception area (highway), a prefecture border notification, a road station, a viewpoint parking lot, and the like.

[0097] Information regarding target objects (for example, position information including longitude and latitude, type information of the target objects, etc.) is registered in the storage unit 25 at the time of product shipment of the electronic device 10. The control unit 11 acquires information regarding newly added target objects from the attached storage medium 50 or by communication using the communication unit 18, and stores the acquired information in the storage unit 25. In this way, it is better for the control unit 11 to have a function of storing update information regarding information about newly added target objects and the like in the storage unit 25.

[0098] Note that the storage unit 25 may be an auxiliary storage device realized using various storage media such as a flash memory (e.g., eMMC, SSD). The storage unit 25 may also be realized using various storage media such as an optical storage media, a magnetic storage media, and a semiconductor storage media.

[0099] [3. Notification Function of Electronic Device 10] The notification function of the electronic device 10 is a function of notifying a user of information using the light receiving unit 12, the radar receiving unit 15, the wireless receiving unit 16, the position information acquisition unit 17, etc. The notification function is a function of notifying information regarding a target called a POI (Point of interest). The notification function has, for example, the functions described below. The notification by the notification function is performed using any one of display on the display unit 13, output of sound by the voice output unit 14, predetermined light emission of the light emitting unit 24, and other perceptible methods for others.

[0100] The control unit 11 has a laser warning function. Specifically, when the control unit 11 determines that it has received laser light for speed measurement from a vehicle speed measurement device corresponding to the laser method using the light receiving unit 12, it performs warning control to issue a warning. The laser light corresponding to the laser method is light of a specific wavelength and is a pulse laser having a predetermined pulse width. The specific wavelength belongs to, for example, the infrared light region, and the wavelength is, for example, 850 nm, 905 nm, 950 nm, or 1900 nm. The pulse width is, for example, approximately 20 ns or approximately 15 ns. The pulse interval is, for example, approximately 80 ms. "Approximately" may be within a predetermined range that can be regarded as the same as or substantially the same as the reference value. When the control unit 11 determines that laser light corresponding to the laser method has been received, for example, it causes the display unit 13 to display a schematic diagram or a photograph of the vehicle speed measurement device corresponding to the laser method stored in the storage unit 25, and reads out the voice data stored in the storage unit 25 to output a voice message "Received laser light. Pay attention to speed" from the voice output unit 14.

[0101] The control unit 11 has a radar warning function. Specifically, when the control unit 11 determines that the radar wave from the vehicle speed measuring device is received by the radar receiving unit 15, it performs warning control to issue a warning. For example, when the control unit 11 determines that the radar wave for speed measurement is received, it causes the display unit 13 to display a schematic diagram or a photograph of the vehicle speed measuring device corresponding to the radar method stored in the storage unit 25, and reads out the voice data stored in the storage unit 25 to output a voice message "It's radar. Pay attention to speed" from the voice output unit 14.

[0102] The control unit 11 has a wireless warning function. Specifically, when the control unit 11 determines that a wireless signal of a predetermined frequency is received by the wireless receiving unit 16, it performs warning control to issue a warning. The control unit 11 scans the frequencies corresponding to the various wireless signals described above. When the control unit 11 determines that a wireless signal is received at the scanned frequency, it causes the display unit 13 to display a schematic diagram or a photograph indicating that the wireless corresponding to that frequency stored in the storage unit 25 for each wireless type has been received, and reads out the voice data stored in the storage unit 25 for each wireless type to output a voice indicating the type of that wireless from the voice output unit 14. For example, when the control unit 11 receives a regulatory wireless signal, it outputs a voice message such as "It's a regulatory wireless signal. Pay attention to speed".

[0103] The control unit 11 has a position warning function (generally referred to as GPS warning). Specifically, the control unit 11 performs warning control for issuing a warning based on the position information of the target stored in the storage unit 25 and the position information acquired by the position information acquisition unit 17. For example, the control unit 11 calculates the distance between the position information of the target and the position information of the electronic device 10, and performs warning control when the calculated distance reaches a predetermined approach distance. For example, when driving on a highway, the control unit 11 performs warning control when approaching the target by 2 km, and in addition, performs warning control when it is determined that the distance to the target is 1 km, 500 m, immediately before, or after passing. For example, for the speed limit point in a tunnel, when driving on a highway, the control unit 11 performs warning control when approaching the target by 2 km, and in addition, performs warning control when it is determined that the distance to the target is 1 km or 500 m. The control unit 11 displays a warning screen on the display unit 13 and outputs sounds such as sound effects, BGM, and voice messages from the voice output unit 14.

[0104] Targets for warning control by the position warning function include, in addition to speed limit points, for example, mouse trap areas, moving orbis areas, following-type enforcement areas, temporary stop enforcement areas, intersection enforcement areas, other enforcement areas, seat belt inspection areas, drunk driving inspection areas, mobile phone inspection areas, other inspection areas, intersection monitoring points, signal violation suppression systems, highway traffic police teams, N systems, traffic monitoring systems, police stations, accident-prone areas, service areas, parking areas, highway oases, highway lengths / continuous tunnels, highway radio reception areas, roadside stations, viewpoint parking lots, parking lots, public toilets, etc.

[0105] Note that the control unit 11 may operate only the notification function set by the user among the above-described plurality of notification functions. Further, a priority may be set for each of the plurality of notification functions or for each of the target objects to be notified, either at the design stage of the electronic device 10 or by the user's setting. In this case, the control unit 11 preferentially issues a notification with a higher priority. For example, a notification with a higher priority may be made more prominent than a notification with a lower priority, or when a notification with a lower priority and a notification with a higher priority conflict, only the notification with a higher priority may be made.

[0106] [4. Other configurations of the electronic device 10] The electronic device 10 is an electronic device having a function of receiving a cancellation wave and a notification function of notifying in response to receiving the cancellation wave, but these functions may be mounted on different electronic devices. In the configuration shown in FIG. 5(A), which is an example of this aspect, the first electronic device 103 has a function of receiving a cancellation wave and a function of outputting a signal corresponding to the reception result to the outside. The first electronic device 103 is also called an antenna unit. The second electronic device 101A acquires the signal output from the first electronic device 103 and has a notification function of notifying in response to the cancellation wave being received by the first electronic device 103 based on this signal. The first electronic device 103 and the second electronic device 101A are connected by, for example, a wired communication path (for example, the cable 104 shown in FIG. 5(A)), but may also be connected by a wireless communication path. The notification may not include notification by, for example, at least any one of display, sound, and light. In the configuration shown in FIG. 5(B), which is an example of this aspect, the electronic device 101B does not have a display unit. The electronic device 101B performs notification by outputting sound from the sound emission hole 105 provided on the front side or causing the light emitting unit 24 to emit light. Further, the electronic device may be an electronic device having an installation position different from that on the dashboard, for example, the front glass of the vehicle (for example, near the upper end of the front glass), or the vehicle's rearview mirror or the ceiling inside the vehicle compartment as the installation position. In the configuration shown in FIG. 5(C), which is an example of this aspect, the electronic device 101B is fixed to the front glass using the attachment member 107 instead of the fixing portion 102. The attachment member 107 is formed using, for example, a plate-shaped member made of metal. Further, the electronic device may be configured to be fixed to any installation position selected by the user from among a plurality of installation position candidates.

[0107] [5. I-Cancellation (Intelligent Cancellation) Function of Electronic Device 10] As described in "3. Notification Function of Electronic Device 10", the control unit 11 has a radar warning function that issues a warning when it determines that the radar receiving unit 15 has received a radar wave from the vehicle speed measuring device. On the other hand, the frequency band of the microwave emitted from the detection device for detecting the approach of a person in the automatic door also belongs to the same X band as the radar wave from the vehicle speed measuring device. Therefore, when the radar receiving unit 15 receives the microwave in that X band, the control unit 11 cannot distinguish whether it is a radar wave emitted from the vehicle speed measuring device or a microwave emitted from a false alarm source other than the vehicle speed measuring device such as an automatic door. As a result, for example, when driving around the false alarm source, if the radar receiving unit 15 receives the microwave emitted from the false alarm source, the control unit 11 will issue a reception warning for the radar wave. To suppress the occurrence of such false alarms, the storage unit 25 (an example of storage means) stores information for specifying a cancellation area for suppressing the notification of microwave reception. When the current position acquired by the position information acquisition unit 17 when the radar receiving unit 15 receives a microwave is within the cancellation area, the control unit 11 performs control not to issue a reception warning for a normal radar wave.

[0108] The information for specifying the cancellation area stored in the storage unit 25 (an example of storage means) may be, for example, the position information of the cancellation registration point, which is the center position of the cancellation area. The cancellation area may be within a range of a predetermined radius centered on the cancellation registration point. The predetermined radius may be, for example, 200 m. The cancellation registration point may use, for example, longitude and latitude. The control unit 11 determines that it is within the cancellation area when the distance between the current position and the cancellation registration point is 200 m or less.

[0109] The control unit 11 is provided with a cancellation function that automatically identifies false alarms caused by an automatic door or the like without manual operation, automatically registers the cancellation registration point in the storage unit 25 (an example of storage means), and controls not to output a reception warning for the radar wave when driving through the same location next time.

[0110] The radar receiving unit 15 includes a patch antenna that receives X-band microwaves, an antenna substrate having a patch antenna that receives K-band microwaves, and a module substrate or the like including a receiving circuit for the microwaves received by those patch antennas. Since the outputs of the patch antenna for the X band and the patch antenna for the K band are input to the same receiving circuit, the radar receiving unit 15 outputs a received signal without distinguishing which band the received microwave belongs to. Therefore, the control unit 11 does not distinguish between bands, and outputs a radar wave reception warning when receiving radar waves in either the X band or the K band.

[0111] Therefore, for example, when a radar wave from a vehicle speed measurement device using the K band is received within a cancellation area set based on a false alarm source that emits X-band microwaves such as an automatic door, a situation occurs where a radar wave reception warning is not output. In addition to vehicle speed measurement devices using the X band, which have been commonly deployed, recently, prefectures where vehicle speed measurement devices using the K band are also deployed have emerged. When driving in such prefectures, if a cancellation area is set as described above, a new problem arises that a radar wave reception warning cannot be issued even when a radar wave from a vehicle speed measurement device using the K band is received.

[0112] In particular, as an example of a vehicle speed measurement device, there is one called MSSS (abbreviation for Mobile Obis of Sensys) that uses the K band. This specific vehicle speed measurement device is characterized by having a smaller output compared to the radar waves emitted from a conventionally used vehicle speed measurement device that uses the X band. Therefore, the reception intensity of the radar waves received by the radar receiver 15 (also referred to as the reception level) is smaller than that of the X band. Thus, there is a situation where the control unit 11 cannot detect the radar waves from the MSSS unless the electronic device 10 approaches the vehicle speed measurement device. Furthermore, the MSSS uses a predetermined modulated wave. Therefore, it takes time for the control unit 11 to recognize that the received microwave in the K band is a modulated wave. And since the vehicle is moving even after first receiving the K band radar waves from the MSSS, when it recognizes that it is the MSSS, the vehicle may be very close to the MSSS. Additionally, since the MSSS is portable and not deployed at a fixed position, the control unit 11 cannot notify the presence of the MSSS using a GPS warning.

[0113] Due to these circumstances, there is a problem that when receiving microwave in the K band that may be radar waves from the MSSS, it is desired to be notified. To solve this problem, the control unit 11 has a function to perform the process of registering and managing the cancellation area as shown below.

[0114] <5-1. Registration process of cancellation registration point (Part 1)> When the control unit 11 receives a normal wave at the radar receiving unit 15, it once registers a cancellation area based on the received position. Then, when the control unit 11 identifies that the received microwave is modulated, it immediately deletes the currently registered cancellation area. As a result, the cancellation area associated with the reception of the current microwave is not registered. Therefore, when traveling the same location and receiving a microwave in subsequent times, the control unit 11 issues a reception warning for the radar wave. MSSS uses a modulated wave in the K band. Therefore, when receiving a radar wave in the K band from MSSS, if the control unit 11 recognizes that it is modulated, it can delete the currently registered cancellation area. As a result, when traveling the same location and receiving a microwave in the K band in the next time, the control unit 11 issues a reception warning for the radar wave. Therefore, the user can know that there may be an MSSS when receiving a radar before detecting a radar wave from MSSS by recognizing the above modulation. An example of the specific processing of the control unit 11 for performing such processing may be configured as follows.

[0115] The control unit 11 acquires the current position when receiving a microwave, and registers the acquired current position as a cancellation registration point when the registration condition is satisfied. FIG. 6 shows an example of the registration process. FIG. 7 is a flowchart showing the function of the control unit 11 that performs the process shown in FIG. 6. In the present embodiment, when the control unit 11 receives a reception signal of a microwave from the radar receiving unit 15, it starts measurement. That is, when the control unit 11 receives a reception signal of a microwave (YES in S1), it acquires current position information (longitude and latitude) from the position information acquisition unit 17, and stores the acquired position information in the volatile memory 112. The control unit 11 sets the current position when receiving a microwave to 0 m and starts measuring the distance (S2).

[0116] Next, the control unit 11 determines whether the first registration prohibition condition is satisfied (S3). The first registration prohibition conditions are four conditions: "Stealth recognized", "MSSS recognized", "Within the cancellation prohibited area", and "Already a registered point". The stealth wave is a radio wave that is emitted only at the moment measured by a predetermined stealth detector, which is a type of vehicle speed measuring device, and its radio wave output is large. When the reception level of the received microwave is high (equal to or higher than a predetermined threshold) and it is a short-time pulse, the control unit 11 determines that stealth is recognized. When the received microwave is a modulated wave, the control unit 11 recognizes it as MSSS. The cancellation prohibited area is an area where registration of the cancellation area is not performed. The control unit 11 determines whether the current position at the 0m point stored in the memory 112 based on the information registered in the storage unit 25 is within the cancellation prohibited area. The cancellation prohibited area is, for example, various trap zones such as a predetermined range based on a fixedly installed vehicle speed measuring device, a place where cancellation is likely to be carried out using a portable vehicle speed measuring device, etc., a my area registered by the user, a zone 30 area, etc. The predetermined range based on the vehicle speed measuring device is, for example, within a 1100m circle from the installation position of a radar-type orbis or an H-system type orbis, and a range that is ±40 degrees with respect to the emission direction of the orbis. The distance and angle are just examples and can be changed as appropriate. The determination of whether it is an "already registered point" is, for example, the control unit 11 determines whether there is a cancellation registration point within a certain range from the current position. If there is a cancellation registration point within the certain range, it is determined that it is already a registered point. This suppresses the duplicate registration of the cancellation area based on the same false alarm source. The certain range is, for example, 100m or less or 200m or less.

[0117] When the control unit 11 satisfies the first registration prohibition condition, it performs skip processing (S4). The skip processing is a process of not registering the cancellation area associated with the reception of the current microwave. Here, the control unit 11 deletes the position information stored in the volatile memory 112. Also, the first registration prohibition conditions are parallel, and the control unit 11 performs skip processing when at least one condition is satisfied. Then, after executing this skip processing, the control unit 11 ends the current registration processing.

[0118] In this embodiment, when the control unit 11 recognizes an MSSS, the suppression is performed such that the point where the microwave is received for executing skip processing is not registered as a cancellation registration point. Therefore, when traveling around the area after the next time, since the cancellation area is not set, when the control unit 11 receives a radar wave from the MSSS, it can notify a reception warning of the radar wave even in a state where the MSSS cannot be recognized.

[0119] On the other hand, when the control unit 11 does not satisfy the first registration prohibition condition (No in S3), it determines whether the vehicle has advanced 30 m from the 0 m point (the position where the microwave received by the memory 112 was received) to the current position (S5). The determination of whether the vehicle has advanced 30 m may be made, for example, based on the actual travel distance obtained from the history of the position information acquired at a predetermined sampling interval from the position information acquisition unit 17, or the straight-line distance between the position of the 0 m point and the current position. The same applies to the distance advanced from this 0 m point hereinafter. The determination of whether the vehicle has advanced 30 m may be configured such that a predetermined margin is set with respect to 30 m, and the control unit 11 determines that the vehicle has advanced 30 m if it is within a certain distance range.

[0120] When the vehicle has not advanced 30 m from the position where the microwave was received (No in S5), the control unit 11 determines whether the vehicle has advanced 150 m (S6). For example, when the positioning based on the GPS signal cannot be properly performed, the control unit 11 may recognize that it has advanced directly from 0 m to 150 m or more without being able to recognize the 30 m passing point. When such a position jump occurs, the control unit 11 performs skip processing (S4). Since the reliability of the position information stored in the memory 112 is low, it suppresses the setting of an incorrect cancellation area based on inaccurate position information. Then, after executing this skip processing, the control unit 11 ends the current registration processing.

[0121] If the result of the branch determination in step S6 is No, the control unit 11 determines whether the first registration prohibition condition is satisfied (S3). Since the reception of the stealth wave and the recognition process of the MSSS are due to the alarm process, it is advisable for the control unit 11 to make these determinations at any time in parallel with this registration process. Then, the branch determination in this step S3 may be performed by the control unit 11 at the time of determination, or it is advisable to use the determination result made for the above-mentioned alarm process. Thereby, the control unit 11 determines whether the first registration prohibition condition is satisfied even until it advances 30 m, and performs skip processing when the condition is satisfied.

[0122] Also, in the above-described example, the position information at the 0 m point is stored in the memory 112 and then it is determined whether the first registration prohibition condition is satisfied. However, it is also possible to determine whether the first registration prohibition condition is satisfied before storing it in the memory 112, and store the position information in the memory 112 when it is not satisfied. If it is done in this way, when the first registration prohibition condition is satisfied when the microwave is received, the process of storing the position information in the memory 112 becomes unnecessary. Along with this, the process of deleting the position information once stored in the memory 112 also becomes unnecessary. Also, in the case of such a modification example, it is advisable for the control unit 11 to continue to make a determination about the first registration prohibition condition even after storing it in the memory 112.

[0123] When the control unit 11 advances 30 m from the point where the microwave is received (Yes in S5), it registers the position information stored in the memory 112 in the storage unit 25 (an example of storage means), which is a non-volatile memory (S7). That is, the control unit 11 registers the position information of longitude and latitude in the storage area of the cancellation registration point that specifies the cancellation area for implementing the I cancellation function. This can be said that the control unit 11 temporarily registers the cancellation registration point. The condition for registration in the storage unit 25 (an example of storage means) is to advance 30 m, and the presence or absence of reception of the microwave at the time of advancing 30 m is not questioned.

[0124] After registering the position information in the storage unit 25 (an example of storage means), the control unit 11 determines whether the second registration prohibition condition is satisfied (S8). The second registration prohibition conditions are "stealth recognized" and "MSSS recognized". When the control unit 11 satisfies the second registration prohibition condition, it performs a process of stopping the registration (S9). That is, the control unit 11 deletes the position information registered (temporarily registered) in the storage unit 25 (an example of storage means). Further, the control unit 11 may perform a process of deleting the current position information at the 0 m point stored in the memory 112. Then, the control unit 11 ends the current registration process.

[0125] In this way, when stealth or MSSS is recognized, a cancellation area is not set based on the position information of the 0 m point where the current microwave was received. Therefore, when the vehicle travels at the same point after the next time and receives a radar wave from a vehicle speed measuring device such as MSSS, the control unit 11 can issue a radar wave reception warning. Thus, the user can know that there may be a vehicle speed measuring device such as MSSS ahead.

[0126] In this way, regardless of whether the microwave received at the current 0 m point is from a false alarm source or from MSSS, when MSSS is recognized, enforcement using MSSS is being carried out in the surroundings. Therefore, in such a case, the control unit 11 does not perform registration of the cancellation registration point.

[0127] Even if the microwave received at 0 m is from a false alarm source, if a vehicle speed measurement device is deployed in front of its traveling direction and it may receive a radar wave from the vehicle speed measurement device during travel before traveling 500 m. In such a case, assuming that the radio wave reception at 0 m is from a false alarm source, and the position information at that time is registered as a cancellation registration point and a cancellation area is set. Then, when a microwave is received during travel within the cancellation area after the next time, no reception alarm is given even if it is a radar wave from a vehicle speed measurement device such as MSSS. In particular, since the reception level of MSSS is low, it is relatively close when a radar wave is received, and the requirement to give an alarm at the reception stage of the K-band microwave before recognizing it as MSSS cannot be solved. On the other hand, in the present embodiment, since the cancellation area is not set as described above, the requirement to give an alarm at the reception stage of the K-band microwave before recognizing it as MSSS can be solved.

[0128] On the other hand, when the control unit 11 does not satisfy the second registration prohibition condition (No in S8), it determines whether the current position has advanced 300 m from the 0 m point (the position where the microwave stored in the memory 112 was received) (S10). The determination of whether it has advanced 300 m may be the same as the determination of whether it has advanced 30 m described above.

[0129] If it has not advanced 300 m (No in S10), the control unit 11 determines whether the second registration prohibition condition is satisfied (S8). Thereby, the control unit 11 repeatedly determines whether the second registration prohibition condition is satisfied until it advances 300 m, and when the condition is satisfied, it performs a process of stopping the registration.

[0130] When it has advanced 300 m (Yes in S10), the control unit 11 determines whether the third registration prohibition condition is satisfied (S11). The third registration prohibition condition consists of three conditions: "recognized level 5", "recognized stealth", and "recognized MSSS". Level 5 means that the reception intensity of the microwave received by the radar reception unit 15 indicates the MAX of the five-level evaluation. This five-level classification may be the same as the reception level that is notified together when performing a reception alarm for the radar wave. For example, it is advisable to set a threshold value, that is, the boundary between level 4 and level 5, so that the reception intensity when approaching a vehicle speed measurement device using the X band to a certain extent is included in level 5.

[0131] In this way, when exceeding 300 m, in addition to stealth recognition and MSSS recognition at 300 m or less, the reception level of the microwave is also monitored. When the control unit 11 satisfies the third registration prohibition condition, it performs a process of canceling the registration (S9). That is, the control unit 11 deletes the position information registered (temporarily registered) in the storage unit 25 (an example of storage means). Further, the control unit 11 may perform a process of deleting the current position information at the 0 m point stored in the memory 112. Then, the control unit 11 ends the current registration process. The reception of the microwave at level 5 can be presumed to be from the vehicle speed measurement device in the X band, and the microwave received at 0 m can be presumed to be the radar wave from this orbis. Therefore, the control unit 11 does not register at the cancellation registration point.

[0132] When the control unit 11 does not satisfy the third registration prohibition condition (No in S11), it determines whether the current position has advanced 500 m from the 0 m point (the position where the microwave stored in the memory 112 was received) (S12). The determination of whether it has advanced 500 m may be the same as the determination of whether it has advanced 30 m or 300 m described above.

[0133] Thereby, between 300 - 500 m, the control unit 11 monitors the stealth recognition, the MSSS recognition, and the reception level of the microwave. When level 5 is recognized, it deletes the temporarily registered data stored in the storage unit 25 (an example of storage means) and cancels the registration (S9).

[0134] If the MSSS, stealth, or level 5 is not recognized even after advancing 500 m, it can be inferred that the microwave detected at 0 m is from a false alarm source rather than a vehicle speed measurement device. Furthermore, it can be presumed that there is no vehicle speed measurement device that can be received within the cancellation area set based on the position of the subsequent false alarm source. Therefore, the registration process is completed without deleting the position information registered in the storage unit 25 (an example of storage means).

[0135] In this embodiment, the temporary registration of position information performed when advancing 30 m is registered in the same storage area as the cancellation registration point for realizing the normal I cancellation function. Therefore, if no deletion process is performed in particular, it will be registered as a normal one as it is. That is, in this "registration completed" process, the control unit 11 does not perform any new process on the storage unit 25 (an example of storage means). The control unit 11 may delete the position information stored in the memory 112 when this registration is completed.

[0136] Also, in the case of an unmodulated radio wave in the K band, it is recognized as not being MSSS. This recognition as not being MSSS includes cases where it cannot be recognized even if it is actually a modulated wave. Then, the position information temporarily registered when the received intensity of the microwave does not reach level 5 is formally registered as the cancellation registration point.

[0137] The "cancel registration" process is a process of not registering when receiving radio waves that may be from a vehicle speed measurement device such as Obis. When the radar wave is received from the vehicle speed measurement device for the first time, the I cancellation registration process is performed according to the above-described procedure, but a radar wave reception alarm is issued. Therefore, when the "skip" or "cancel registration" process is performed, the radar wave reception alarm is issued both for the first time and for the second time and subsequent times.

[0138] In this embodiment, from 30 m to 300 m, it is not considered whether it is level 5. This is because if radar waves are received from a vehicle speed measurement device in the X band, after the first detection (0 m), it will not reach level 5 at 300 m. It will reach level 5 after advancing more than 300 m and approaching the vehicle speed measurement device. Therefore, there is a possibility that it is not a normal vehicle speed measurement device if it reaches level 5 before advancing 300 m and does not reach level 5 after advancing 300 m. Therefore, in such a case, there is no need to cancel the registration, and the registration process at the cancellation registration point is performed. On the other hand, for a normal vehicle speed measurement device, even if it reaches level 5 before 300 m, level 5 will be maintained even if it exceeds 300 m. Therefore, when the third registration prohibition condition is satisfied at the time of passing 300 m, it is sufficient for the control unit 11 to perform the "cancel registration" process there. By doing so, it is possible to reduce the judgment conditions to be performed up to 300 m without reducing the accuracy of appropriately performing the cancellation registration point.

[0139] In this embodiment, the control unit 11 does not register immediately when receiving the microwave, but makes a provisional registration when 30 m has elapsed, and then monitors the situation. As a result, even if microwave is received from a false alarm source at 0 m, when a vehicle speed measurement device exists around it, the setting of the cancellation area can be suppressed.

[0140] Also, in order to recognize that the received microwave is a modulated wave, it is necessary to travel a certain distance and approach the MSSS to receive a radar wave with a large reception level. On the other hand, in this embodiment, it is set to travel 500 m from the start of reception to the completion of registration. Therefore, if the microwave being received is a radar wave from the MSSS, as it approaches the MSSS, the amplitude of the microwave also increases, and it can be recognized that it is modulated. Accordingly, in the area where the MSSS exists around, the registration of the cancellation area is suppressed.

[0141] In the above-described embodiment, the recognition process of MSSS determines whether the microwave is a modulated wave, but other conditions such as the frequency used in MSSS may be added. However, it is preferable to base it on the presence or absence of modulation without adding additional conditions. By doing so, recognition can be achieved in a short time, and it is possible to limit the registration of the cancellation area for a vehicle speed measurement device using a modulated wave microwave of a new frequency.

[0142] Also, the radar wave emitted from a vehicle speed measurement device using a K-band microwave currently in use has a low reception intensity and does not reach level 5. On the other hand, when the reception intensity of the radar wave emitted from a vehicle speed measurement device using the K-band to be developed in the future becomes large and there is one at level 5, the control unit 11 can perform a process of canceling registration based on the condition of "level 5 recognition" of the third registration prohibition condition.

[0143] <5-2. Registration Process of Cancellation Registration Point (Part 2)> FIG. 8 shows an example of the registration process of the cancellation registration point performed by the control unit 11. This registration process (2) is basically the same as the above-described registration process (1). The control unit 11 sets the position where the microwave is received as 0 m, temporarily registers the position information at the 0 m point when traveling 30 m, and completes the registration when traveling 500 m without satisfying the conditions for registration deletion. With this completion of registration, the temporarily registered position information becomes a regular cancellation registration point, and a predetermined distance range around the cancellation registration point becomes a cancellation area.

[0144] Specifically, the control unit 11 determines whether the registration conditions are satisfied. If satisfied, it acquires the current position information and stores it in the memory 112. The registration conditions are six conditions: "RD reception occurred", "not in the cancellation prohibited area", "not in my cancellation area", "no I cancellation area within a radius of 100 m", "not stealth", and "not receiving a modulated wave".

[0145] "RD reception occurred" means that the vehicle speed measuring device has received microwave signals in the X-band or K-band. When the control unit 11 receives the received signal from the radar receiving unit 15, it recognizes that "RD reception occurred".

[0146] "Not in the cancellation prohibited area" means that the current position is not in the cancellation prohibited area. The cancellation prohibited areas are "opposite within a range of ±40 degrees within 1100 m from the installation position of the "RD (radar) type orbis·H system type orbis", "within a range of 600 m outside of temporary stops and intersections in the trap zone", "within a range of 600 m in the my area", "within a range of 600 m outside of temporary stops and intersections in the tunnel trap zone", and "within the zone 30 area". The trap zone and the tunnel trap zone are, for example, places where enforcement has been carried out in the past, and it is particularly good to assume places where enforcement is frequently carried out. The "my area" is an area registered by the user. When the control unit 11 enters the my area, it notifies a predetermined warning. The my area is an area that effectively notifies the user, for example, by registering the locations where the mobile orbis frequently appears or the locations of newly installed vehicle speed measuring devices.

[0147] The "my cancellation area" is an area where the user registers to suppress the received warning of radar waves. Instead of the automatic registration of the above-described I cancellation, the control unit 11 that has received the user operation registers in the storage unit 25 locations where the received warning of radar waves is frequently notified, such as locations where no enforcement devices such as automatic doors are installed. Within the my cancellation area, the received warning of radar waves is suppressed in the same manner as in the I cancellation area.

[0148] After the control unit 11 has traveled 30 m while satisfying the above registration conditions and if the registration conditions remain the same, it temporarily registers the position information of the 0 m point in the storage unit 25 (an example of storage means) as the I cancellation area. After registering (temporarily registering) at this 30 m point, the control unit 11 completes the registration by traveling 500 m. However, if a stealth warning occurs, a modulated wave is detected, or the received level becomes maximum or higher (level 5 or higher) during the 500 m travel, the temporary registration is deleted.

[0149] Also, if the power is turned off before driving for 500 m, the registration is completed. That is, in the present embodiment, the storage area for recording the provisional registration position information and the storage area for registering the regular cancellation registration point are the same. If the condition for deletion is not provided even after driving for 500 m, the provisional registration position information is not deleted and is not rewritten to another storage area. That is, the provisionally registered position information is used as the cancellation registration point as it is. And since the storage unit 25 (an example of storage means) is a non-volatile memory, if the power is turned off before driving for 500 m, the deletion process of the provisional registration is not performed, and thus the registration is completed as it is.

[0150] <5-2. Deletion Process of Cancellation Registration Point>

[0151] (5-2-1. Deletion Process Based on MSSS Recognition (Modulation Recognition)) In the "5-1. Registration Process of Cancellation Registration Point", if the radar wave from the MSSS cannot be demodulation-identified even when received, it is normally registered as an I cancellation. Therefore, the control unit 11 may be provided with an operation of deleting the cancellation area registered at the I cancellation nearby when the modulation is identified the next time it passes by.

[0152] Even if the microwave received when registering the cancellation registration point is the orbis of the MSSS, it may not be possible to demodulation-identify it. In particular, the microwave received at the 0 m point is from a false alarm source. When the radar wave from the MSSS is received on the way, it takes time to demodulation-identify it, and it may be just in time to demodulate it near 500 m, and there may be cases where it is too late. In such a case, since it cannot be recognized as the MSSS, it may be registered as a cancellation point.

[0153] In addition, the MSSS is portable and not permanently installed at a fixed location. Therefore, if the MSSS is not in operation when the cancellation registration point is registered, the cancellation area will be set through normal processing without meeting the registration prohibition conditions. After the cancellation area is set, enforcement using the MSSS may be carried out within or near the cancellation area.

[0154] Once the cancellation registration point is registered, even if the radar wave during travel in the cancellation area is received, the reception warning of the radar wave is suppressed. Therefore, if the modulation cannot be identified even when receiving the radar wave from the MSSS during the 500m travel as described above, the position information at 0m will be registered as the cancellation registration point. Then, afterwards, if the MSSS is installed at the same location and the radar wave from the MSSS is received, a situation where no reception warning of the radar wave is given will occur.

[0155] Therefore, when it can be recognized that the radar wave from the MSSS during travel is modulated, by deleting the information of the previously registered predetermined cancellation area, when the radar wave from the MSSS is received from the next time onwards, the control unit 11 can give a reception warning of the radar wave even before determining the presence or absence of modulation.

[0156] By doing so, when the control unit 11 recognizes the MSSS after registration when meeting the predetermined conditions, it deletes the cancellation registration point and enables an earlier reception warning of the radar wave from the next time. This can solve the problem of wanting to be notified earlier when receiving the microwave of the K band, which may be the radar wave from the MSSS described above.

[0157] The control unit 11 having a function of performing this deletion process may be configured as follows, for example. When the control unit 11 identifies the modulation of the microwave received at a place where a cancellation area has already been registered, it deletes that cancellation area. Further, the control unit 11 may have a function of deleting nearby cancellation areas. By doing so, the cancellation areas existing in the area where the enforcement using MSSS is carried out and in its vicinity are deleted, and when the control unit 11 travels in that area after the next time, if it receives a radar wave from MSSS, it can issue a reception warning.

[0158] Also, in the actual process, without making a conditional determination of "the microwave received at a place where a cancellation area has been registered", that is, "the microwave received while traveling within the cancellation area", when the received microwave is a modulated wave in the K band, that is, when MSSS is recognized, it is advisable to delete the cancellation areas in the vicinity. By doing so, the deletion process can be performed easily.

[0159] The control unit 11 accesses the storage unit 25 (an example of storage means) and deletes all the cancellation registration points within a predetermined distance centered on the point where MSSS is recognized, that is, the point where modulation is recognized. The predetermined distance may be, for example, 500 m. The control unit 11 can recognize modulation 200 - 300 m in front of the installation position of MSSS. And the radar wave emitted from MSSS can be received a little further in front. Therefore, it is decided to delete all the cancellation registration points within a range of 500 m with a margin. As a result, when the control unit 11 receives a radar wave from MSSS, it can issue a reception warning for the radar wave even before recognizing the modulation.

[0160] (5-2-1-1) When the control unit 11 receives the radar wave of the vehicle speed measurement device in the X-band, it is advisable not to perform the deletion process of the cancellation registration point. The vehicle speed measurement device in the X-band has a high reception level, for example, like stealth, can detect from a farther point compared to MSSS, and can be recognized in a relatively short time because it is an unmodulated wave. Therefore, different from MSSS, when receiving the radar wave of stealth during the movement from 0 m to 500 m where the cancellation registration point is registered, it can surely recognize it and stop the registration. Therefore, the possibility that the cancellation registration point is erroneously registered based on the reception of the radar wave of stealth is low, and the possibility that there is a false alarm source is high. Furthermore, many of the vehicle speed measurement devices using stealth waves are portable and are not always regulated. Therefore, by not performing the deletion process of the cancellation registration point, it is possible to suppress the occurrence of false alarms when driving after the next time.

[0161] (5-2-2. Deletion Process Based on Non-Reception of Radar) When the control unit 11 registers the cancellation registration point in the storage unit 25 (an example of storage means), it also records the information of the registration date in association. Then, the control unit 11 determines whether the current position is within the cancellation area, and when entering the cancellation area, it determines whether a radar wave is received during driving within that area. The control unit 11 manages the passing history information for each cancellation registration point and records the presence or absence of the reception of the radar wave when driving through that area.

[0162] Except for the registration date, when the control unit 11 passes 8 times thereafter and does not receive the radar even once (for example, when no reception signal is output from the radar reception unit 15), the registered cancellation registration point is deleted.

[0163] (5-2-3. Deletion Process Based on User Operation) The electronic device 10 has a function of deleting the cancellation registration points registered according to the user's manual operation. When the deletion of all cancellation areas is selected, the control unit 11 cancels the registration of all cancellation registration points. The configuration for the user to manually delete is not particularly limited. For example, the control unit 11 causes the display unit 13 to display options (such as soft buttons) for selecting information to be deleted, such as "cancellation area", "my area", "my cancellation area", etc., and a delete button (such as a soft button). The control unit 11 selects the information corresponding to the user's operation received by the input unit 19 (for example, the touch sensor 191), here "cancellation area". The control unit 11 deletes the corresponding information, here all the cancellation registration points, according to the user's operation received by the input unit 19 (for example, the touch sensor 191).

[0164] <5-3. Notification within the cancellation area>

[0165] (5-3-1. Notification of I cancellation) The control unit 11 performs a predetermined notification when entering the I cancellation area and when receiving a radar wave within the cancellation area. The cancellation area may be, for example, 200 m around the cancellation registration point.

[0166] The control unit 11 obtains the distance between the current position acquired from the position information acquisition unit 17 and the cancellation registration point stored in the storage unit 25 (an example of a storage means). When the distance between the two is 200 m or less, it is determined that the device is within the cancellation area.

[0167] When the control unit 11 enters the cancellation area, it issues a predetermined warning. This warning may, for example, output a message such as a predetermined phrase, e.g., "What's this? This is the i-cancellation area." as shown in Fig. 9(a) by voice. Also, in this example, since the display unit 13 displays a predetermined character and the electronic device 10 is of a type where the character gives a predetermined notification, the phrase also corresponds to the character. Also, in the case of an electronic device 10 that is not of such a character type, it is advisable to output a voice message such as "Entered the i-cancellation area." Further, the control unit 11 may instead of voice, text-display a message on the display unit 13 or display a predetermined icon, image, etc.

[0168] Also, when the control unit 11 receives radio waves, i.e., a predetermined microwave, within the i-cancellation area, it notifies that cancellation is in progress. The phrase when receiving this cancellation radar wave may be, for example, as shown in Fig. 9(b), "There's a radar wave coming now... but it's fake, right?" Also, this phrase is just an example, and it is advisable to give a notification indicating that microwave reception has occurred, such as "Within the cancellation area" or "Radar received, i-cancellation in progress." The cancellation area report by the control unit 11 outputs the above warning when receiving radio waves within the area, and when continuously receiving radio waves, it may continue to output the "Within the cancellation area" warning as it is.

[0169] For the determination of whether it is within the cancellation area, in addition to the range within 200 m from the above cancellation registration point, conditions such as "The registration dates are not the same" and "When obtaining the radar reception rate from the past passage history, it exceeds the threshold" may be added.

[0170] When adding the registration date as a condition, if the registration dates are the same, the control unit 11 gives a radar warning even when entering the i-cancellation area. That is, when the control unit 11 receives a radar wave while traveling within the cancellation area, if it is the same as the registration date of the cancellation registration point of that cancellation area, it outputs a normal radar wave reception warning.

[0171] When adding the condition of "when obtaining the radar reception rate from the past passing history and exceeding the threshold value", the control unit 11 does not determine that it is within the cancellation area in an area below the threshold value where there has been little reception of radar waves in the past. Therefore, when receiving a radar wave while driving within that area, the control unit 11 issues a normal radar wave reception warning.

[0172] As also described in "5-2-2. Deletion Process Based on Non-Reception of Radar", the control unit 11 performs a process of memorizing whether reception occurred when actually passing. If there is no continuous reception 8 times, the control unit 11 deletes the cancellation registration point. On the other hand, if there is reception, for example, about 1 or 2 times out of 8 times, the control unit 11 does not delete the cancellation registration point, but does not issue a warning based on I-cancellation. That is, the control unit 11 issues a normal radar wave reception warning.

[0173] In this way, for example, if the false alarm source is an automatic door, it emits microwaves during the business hours of the facility such as in the daytime, but does not emit microwaves after business hours such as at night. Therefore, for example, when frequently driving at night, the electronic device 10 does not receive microwaves, but when sometimes driving during the daytime as well, the electronic device 10 receives microwaves there, so the reception rate is low. In a usage situation where there is a false alarm source and sometimes driving during the daytime as well, the control unit 11 retains the cancellation area. As a result, when the proportion of daytime driving increases and the reception rate also increases, the control unit 11 determines that it is within the cancellation area and performs notification based on I-cancellation.

[0174] (Processing When MSSS is Recognized) When the control unit 11 recognizes that the received microwave is an MSSS, it switches to the MSSS alarm and performs a process of deleting the above-mentioned nearby cancellation registration points. As a result, the user can recognize the presence of the MSSS. Also, as the nearby cancellation registration points are deleted, when the vehicle travels the same location after the next time, when the control unit 11 receives the radar wave from the MSSS, it notifies the reception alarm of the radar wave (not cancelled by I). As a result, the user can recognize that they are receiving microwave signals that may be from an MSSS at a farther position.

[0175] The MSSS alarm may output by voice (such as "Receiving MSSS", "There is an MSSS ahead", etc.) that it is receiving the radar wave of the MSSS, display text in a telop on the display unit 13, or display pictures, CG, etc. on the alarm screen.

[0176] <5-4. Alarm Mode Custom Setting> Regarding the above-mentioned I cancellation function and various registration areas, the items to be used are selected according to the setting of the alarm mode (see Fig. 10). Each mode of "Normal", "Minimum", "Special", and "All On" has the operating items set and cannot be changed. When the "Custom" mode is selected, the user can select ON / OFF for each item. Regarding whether the electronic device 10 operates in any of the modes, it is preferably configured to be switched according to the user's manual operation. There is no particular limitation on the configuration that allows the user to switch manually. For example, based on the user's screen touch operation, the control unit 11 causes the display unit 13 to display the selection options (for example, soft buttons) of each mode. The control unit 11 selects the mode corresponding to the user's operation received by the input unit 19 (for example, the touch sensor 191) and then operates in the selected mode. Also, when "Custom" is selected, the control unit 11 causes the display unit 13 to display the selection options (for example, soft buttons) of each item. The control unit 11 enables the item selected as ON according to the user's operation received by the input unit 19 (for example, the touch sensor 191) and operates.

[0177] In the item of the custom "Other I Cancel Phrase" in the alarm mode, turn on / off both the area entry / cancel phrase. Since the item of "Other I Cancel Phrase" is fixed to OFF when selecting a mode other than custom, the control unit 11 does not speak. Also, even if the I cancel phrase is turned off, the control unit 11 may display a predetermined sentence as a telop.

[0178] <5-5.I Cancel (Vending Machine / Automatic Door Edition)> As described in "5-3-1. Notification of I Cancel", when the day when the radar wave is received is the same day as the registration day of I cancel, the control unit 11 basically performs control to issue a radar warning even when entering the I cancel area. For those with a short reception interval of radar waves and a distance of less than 30 m, they are registered immediately on the same day instead of the next day, and even on the same day as the registration day, they are cancelled and normal warnings are not issued. This can suppress the occurrence of false alarms when passing in front of the same vending machine or the like multiple times on the same day, as the I cancel function will work from the second time onwards.

[0179] At this time, the target is 10 m to less than 30 m. Since those less than 10 m may be interference waves, it is better not to deal with them. The measurement of the reception distance may be calculated from the time of the received cycle. For example, when received at 30 km / h and 3 cycles (0.6S×3) (assuming 1 cycle is 0.6S), 8m / s×1.8 = 15m, so it is registered immediately. In this case, it is necessary to include the number of received cycles in the radar communication.

[0180] [6. Prefectural Identification] The electronic device 10 stores and holds in the storage unit 25 information regarding the deployment status of a specific vehicle speed measuring device, such as MSSS, for each area. The area may be, for example, in units of prefectures. The information regarding the deployment status of the MSSS may be information that distinguishes installation / uninstallation in units of prefectures.

[0181] The control unit 11 recognizes where it is on the map data stored in the storage unit 25 from the current position acquired by the position information acquisition unit 17, and recognizes the prefecture where it currently exists. Then, the control unit 11 performs various detection and notification processes according to the operation conditions set based on the information on the deployment status of the MSSS set for each prefecture. By doing so, the control unit 11 can perform appropriate notification processes according to the deployment status of the MSSS in the prefecture.

[0182] The setting of the operation conditions for each prefecture may be, for example, various settings (RD settings) for implementing the radar warning function such as the sensitivity for receiving radar wave warnings and the detection / notification targets. In addition to the RD settings, it is also good to change the settings for implementing the wireless warning function and the position warning function.

[0183] Also, at the time of application, the MSSS is assumed to be deployed, for example, in Hokkaido but not deployed, for example, in Aichi Prefecture. And this deployment status may be changed in the future. Therefore, it is good to update the data of the information on the deployment status of the MSSS stored and held in the storage unit 25 (an example of the storage means) at an appropriate timing. This data update may be performed by free WiFi in the same way as the publicly disclosed information updated regularly, for example, and may be distributed together with the publicly disclosed information. By distributing them together like this, it is good because the user can acquire and update the publicly disclosed information and the information on the deployment status of the MSSS with one update process. Also, the information on the deployment status of the MSSS is simple as installed / uninstalled and is information set in prefecture units like the publicly disclosed information. Therefore, for example, the deployment status of the MSSS may be stored in the header part of the publicly disclosed information and distributed as one file. It is good to implement various functions shown below using this prefecture identification function.

[0184] Also, the deployment status and the publicly disclosed information may be stored and held in the storage medium 50 instead of the storage unit 25. In this case, the control unit 11 may access the storage medium 50 to obtain the deployment status and the publicly disclosed information in the prefecture of the current position. The same applies in the following description.

[0185] <Processing for Unmodulated K - Waves>

[0186] (6 - 1 - 1.Processing in Prefectures without MSSS Deployment) The electronic device 10 has a function of automatically ignoring unmodulated K - waves in prefectures without MSSS deployment. The radar waves emitted from the MSSS are modulated in the K - band. On the other hand, the microwaves emitted from false - alarm sources using the K - band such as vending machines are not modulated. In prefectures where the MSSS is not deployed, the electronic device 10 does not receive the modulated radar waves in the K - band from the MSSS. Therefore, when the current location is in a prefecture that has not introduced the MSSS, the control unit 11 suppresses the reception alarm of the radar wave even if an unmodulated K - band wave is received. By doing so, it can be expected that false alarms based on the microwaves emitted from vending machines can be completely eliminated.

[0187] For the reception determination of unmodulated K - band waves, it is good to determine that there is no modulation when modulation cannot be recognized. That is, if microwaves of a modulated wave in the K - band are received, but it cannot be identified that it is modulated at the beginning of reception, it is judged as unmodulated. Thus, for example, when unmodulated microwaves in the K - band are emitted from a vending machine, the electronic device 10 continuously receives the unmodulated K - band microwaves. Therefore, since the control unit 11 does not issue a reception alarm for the radar wave, false alarms can be suppressed.

[0188] For the suppression of the reception alarm, an alarm that is suppressed and different from the normal reception alarm may be given, but it is better not to give a reception alarm and not to sound it. The suppressed alarm, for example, does not sound an alarm tone, does not output a voice message, and is made into a display on the display unit 13, which is less conspicuous than the normal reception alarm. When displaying on the display unit 13, for example, the display color of the alarm screen may be made different, or it may be a display of only characters.

[0189] (6 - 1 - 2.Processing in Prefectures with MSSS Deployment) On the one hand, the electronic device 10 has a function of not ignoring the unmodulated K wave automatically in the prefectures where MSSS is deployed. When the current position is in a prefecture where MSSS is deployed, if the control unit 11 receives a microwave in the K band without modulation, it will issue a reception warning for the radar wave. To determine the presence or absence of modulation of the radar wave emitted from MSSS, it is necessary to receive a certain level of strong radio wave. In the case of MSSS, since the radio wave intensity is low, it is necessary to approach the orbit of MSSS to a certain extent to identify the presence or absence of modulation. When checking the modulated wave in the K band and sounding the alarm, since the alarm is output after approaching the orbit, the alarm start distance is close to MSSS and the alarm distance becomes short. This phenomenon may seem to have a reduced sensitivity when viewed by others. Therefore, in the prefectures where MSSS is deployed, when the control unit 11 receives a K wave without ignoring the unmodulated K wave, it will issue a reception warning for the radar wave anyway. Thereby, the user does not think that the sensitivity has decreased.

[0190] (6-1-3. Processing when recognizing MSSS) When the control unit 11 confirms that the received microwave in the K band is a modulated wave, it will issue an MSSS alarm, and if it is an unmodulated wave, it will stop the reception warning for the radar wave. When the modulated wave can be confirmed, the control unit 11 will issue an MSSS alarm, so that the user can know the presence of MSSS. In addition, the user can confirm that the initial reception warning for the radar wave was based on the radar wave of MSSS, and can know the possibility of the presence of MSSS before recognizing the modulated wave.

[0191] When the control unit 11 is in an unmodulated state without modulation, it may notify that it is a false alarm source or a vending machine. By doing so, the user can actively know that the previously notified reception warning for the radar wave was not from MSSS. In addition, the confirmation of the unmodulated wave can be, for example, when modulation cannot be confirmed until the microwave is no longer received, or when modulation cannot be confirmed even when the reception level is greater than or equal to a certain level. When the reception level is greater than or equal to a certain level, for example, it should be set to a level at which modulation can be recognized for the radar wave of MSSS.

[0192] The processing during the recognition of this MSSS may be executed, for example, in the prefectures where MSSS is deployed. In the case of prefectures where MSSS is not deployed, since the unmodulated K-wave is ignored, it is advisable for the control unit 11 to issue an MSSS alarm when a modulated wave is confirmed.

[0193] (6-1-4. Setting whether to ignore the unmodulated K-wave) In the above-described embodiment, whether to ignore the unmodulated K-wave is switched based on the deployment status of the MSSS, but it is preferable to have a function that allows the user to manually set it. For example, when the number of prefectures where MSSS is deployed increases, a radar wave reception alarm will be issued without ignoring the unmodulated K-wave. This will lead to an increase in alarms based on false alarm sources. For users who do not prefer such alarms, by selecting the mode of ignoring the unmodulated K-wave, alarms according to the user's preference will be issued.

[0194] On the other hand, if there is a time lag in the update of the deployment status of the MSSS and the deployment information is not publicly available in the first place, when the control unit 11 is set to not deploy the MSSS even though the MSSS is actually deployed, the control unit 11 will perform the process of ignoring the unmodulated K-wave. Then, the alarm based on the reception of the radar wave from the MSSS will be delayed. Users who do not prefer such a situation can select the mode of not ignoring the unmodulated K-wave to get the alarms according to their preference.

[0195] Also, when the number of prefectures where the above MSSS is used increases and exceeds a set predetermined number, it is advisable to be able to set whether to ignore the unmodulated K-wave.

[0196] <6-2. Changing the reception sensitivity of the radar> The control unit 11 may perform control to set the radar reception sensitivity based on the deployment status of the MSSS. For example, the control unit 11 refers to the map data based on the current position information and recognizes the prefecture where it currently exists. When the current prefecture has the MSSS deployed, the control unit 11 increases the reception sensitivity of the radar, and when the MSSS is not deployed, the control unit 11 decreases the reception sensitivity of the radar. In the area where the sensitivity is increased, the radar wave from the MSSS can be detected and notified more reliably. Also, in the prefectures where the MSSS is not deployed, the occurrence of false alarms can be suppressed by lowering the reception sensitivity of the radar and the like.

[0197] <6-3. Full Auto [MSSS] Function> The full auto [MSSS] function is a function that automatically changes the RD setting for each prefecture according to the MSSS deployed for each prefectural police. In this specification, the term "prefectural police" means the prefectural police, including not only each prefecture but also the police organizations established in Tokyo Metropolis, Hokkaido, Osaka Prefecture, and Kyoto Prefecture.

[0198] The control unit 11 refers to the map data based on the current position information and recognizes the prefecture where it currently exists. Then, when the current position is in a prefecture where the MSSS is deployed, the control unit 11 changes the setting to a state where it is easy to receive the radar wave. For the change to the easy-to-receive state, for example, in the MSSS enforcement area or on the enforcement route, the highest sensitivity may be set. The position information in the MSSS enforcement area and on the enforcement route is stored in the storage unit 25 (an example of a storage means). The control unit 11 determines whether the acquired current position exists within those areas, etc., and changes the sensitivity when it is determined that it is within the area, etc. Also, when it deviates from those areas, etc., the control unit 11 may return to the original sensitivity.

[0199] The control unit 11 may also be set to false alarm reduction OFF, reception sensitivity SE (Super Extra: highest sensitivity), or AAC / SE. Here, the AAC function is a function that suppresses unnecessary alarms when the vehicle is stopped or traveling at low speed. When traveling at low speed, for example, it may be set to less than 30 km / h. AAC / SE is to set the sensitivity to SE when traveling at a speed of 30 km / h or more and not at low speed. Also, the control unit 11 may be set to AAC / ASS. The ASS function changes the reception sensitivity according to the speed. For example, it may be set to City (low sensitivity) when the speed is 30 km / h to 39 km / h, Extra (medium sensitivity) when the speed is 40 km / h to 79 km / h, and Super Extra (high sensitivity) when the speed is 80 km / h or more. Therefore, during traveling at a certain speed or above, the control unit 11 detects the reception of radar waves with the highest sensitivity.

[0200] False alarm reduction is to perform control that does not immediately issue an alarm even when receiving K-band microwaves, and only sounds an alarm when receiving a modulated wave K-band. And when false alarm reduction is OFF, such false alarm reduction is not performed, and a radar wave reception alarm is immediately issued when receiving K-band microwaves. In this way, when false alarm reduction is set to OFF, when receiving a radar wave from MSSS, the control unit 11 issues a radar wave reception alarm before the modulation wave is recognized. Therefore, the user can know the possibility of the existence of MSSS from a relatively distant position from MSSS.

[0201] On the one hand, when the current location is a prefecture where MSSS is not deployed, the control unit 11 changes the setting to suppress the warning sound. The suppression of the warning sound may be, for example, to turn on the above false alarm reduction. Thereby, when the control unit 11 receives the K-band microwave, it does not issue an alarm immediately and issues an alarm only when it recognizes that there is modulation. Thereby, the occurrence of false alarms is suppressed. When the false alarm reduction is turned on, in this embodiment, when receiving a K-band microwave for which no modulation or modulated wave can be confirmed, control is performed not to issue an alarm. This control not to issue an alarm may be, for example, not to perform either an alarm by sound or an alarm with a predetermined display on the display screen of the display unit 13. By doing so, the user is relieved from the annoyance caused by false alarms. Also, when the false alarm reduction is ON, it is advisable not to give an alarm by sound and to give an alarm using the display unit. An alarm by sound is likely to be heard and cause annoyance even when the user is looking ahead. Therefore, by not giving an alarm by sound, the annoyance caused to the user by false alarms is reduced. Furthermore, when the control unit 11 receives a K-band microwave for which modulation cannot be confirmed, it may give a notification indicating that it is not the reception of the suppression wave from Obis, such as "Receiving malfunction source".

[0202] If the full auto [MSSS] is turned on, appropriate RD settings will be made for each prefecture. The user does not need to switch the settings at each location. Also, it is advisable to set the initial value of this full auto [MSSS] function to OFF and configure it to be turned on by user settings. It is better to leave the decision of whether to use it to the user's judgment.

[0203] <6-4.Change of registration conditions for I cancellation> The control unit 11 includes MSSS recognition in the registration prohibition condition at the time of registering I cancellation, and performs processing not to register when it recognizes that the received microwave is a modulated wave. The control unit 11 may change this condition based on the deployment status of MSSS. For example, in a prefecture where MSSS is not deployed, it is advisable to remove MSSS recognition from the registration prohibition condition. Also, the control unit 11 may change whether to register or not when there is no modulation depending on the prefecture.

[0204] <6-5. Alarm Type "Full Auto" Function> As described in the item of the above "6-3. Full Auto [MSSS] Function", MSSS is a vehicle speed measuring device using the K band and is also an example of a portable orbis. Portable orbis is not limited to MSSS, and there are, for example, those called JMA manufactured by Nihon Radio Co., Ltd., which differ depending on the type of portable orbis, such as the band and frequency of the microwave used, the presence or absence of modulation, and the modulation method. Furthermore, the deployment of various portable orbis is determined on a prefecture-by-prefecture basis. Therefore, for example, when there are two types of portable orbis, MSSS and JMA, in a certain prefecture, the deployment situation may be such that both MSSS and JMA are deployed, only one of them is deployed, or neither of them is deployed. This is because the deployment situation is determined on a prefecture-by-prefecture basis for the prefectural police to decide whether to adopt a portable orbis and which model to adopt if they do. This deployment situation is stored, for example, in the storage unit 25 or the storage medium 50.

[0205] (6-5-1. Two Types of Alarm Types: "Accuracy" and "Responsiveness") The alarm type "full auto" function is a function that automatically sets the "alarm type" according to the deployment situation of the orbis for each prefecture. The deployed predetermined orbis is, for example, a portable orbis in which the modulation frequency of the radio wave emitted as the control wave is specified. This deployment situation may be stored and held, for example, in the storage unit 25 or the like.

[0206] The alarm type has accuracy and responsiveness. "Accuracy" is a mode in which a predetermined orbis deployed is detected and an alarm is issued, and to a certain extent, an alarm cannot be issued unless approaching a portable orbis, but the notification of an alarm (also called a false alarm) based on the reception of radio waves emitted from devices and equipment other than the portable orbis is reduced. False alarms include, for example, alarms notified based on the reception of K-band microwaves emitted from a collision prevention system installed in a Mazda car, or microwaves emitted from a vending machine or an automatic door. This "accuracy" may reduce the notification of false alarms and enable an alarm to be issued when modulated radio waves from MSSS or the like are detected, similar to the case where false alarm reduction described in "6-3. Full Auto [MSSS] Function" is turned on.

[0207] The alarm type "accuracy" identifies and alarms radio waves from orbises whose modulation frequencies can be specified, such as MSSS and JMA. The control unit 11 operating with this "accuracy" may issue an alarm, for example, when it determines that the received radio wave is in the K-band of a predetermined frequency and is modulated. In this way, the control unit 11 does not issue an alarm even if it receives an unmodulated radio wave from, for example, a vending machine. As a result, the notification of false alarms is reduced. Since the detection distance depends on the sensitivity at which modulation can be received, it is, for example, about 100 m in front of a portable orbis. Also, the microwave detection circuit of this embodiment can detect the X-band and the K-band separately. Therefore, although the radar wave emitted from an orbis using the X-band, which has been conventionally used, is an unmodulated wave, when a predetermined microwave is received during the reception of the X-band, it is possible to detect that it is an orbis using the X-band.

[0208] When operating in the alarm type "accuracy", when receiving microwave in the K band where no modulation or modulated wave can be confirmed, control is performed so as not to issue an alarm as described above. This control not to issue an alarm may, for example, be such that neither an alarm by sound nor an alarm with a predetermined display on the display screen of the display unit 13 is performed. By doing so, the user is relieved from the annoyance of being falsely alarmed. Also, when operating in "accuracy", it is preferable to perform an alarm on the display unit without issuing an alarm by sound. An alarm by sound is likely to be heard and cause annoyance even when the user is looking ahead. Therefore, by not issuing an alarm by sound, the annoyance of the user being falsely alarmed is reduced. Further, when the control unit 11 receives a microwave in the K band for which modulation cannot be confirmed, it may give a notification indicating that it is not the reception of an enforcement wave from the Obis, such as "Receiving malfunction source".

[0209] The alarm type "reactivity" can alarm MSSS, JMA, and other radar-type Obis from a distance in the same way as when the false alarm reduction described in "6-3. Full-auto [MSSS] function" is turned off, but it is a mode in which false alarms also increase. The control unit 11 operating in this "reactivity" may perform the following processes (1) to (3), for example.

[0210] (1) When the control unit 11 receives a predetermined radio wave in the K band used by, for example, MSSS, it issues an alarm regardless of the presence or absence of modulation. (2) When the current position is sensed to enter the enforcement route, the control unit 11 sets the sensitivity to the highest sensitivity of super extra. The determination as to whether the current position is on the enforcement route may be made, for example, by the following process. The control unit 11 accesses the storage unit 25 and acquires the road name of the currently traveled road from the current position information and the map data. Then, the control unit 11 accesses the public enforcement information stored in the storage unit 25 and checks whether the acquired road name is designated as an enforcement route at the current date and time. The control unit 11 determines that it is on the enforcement route if it is designated as an enforcement route, and determines that it is outside the enforcement route if it is not designated. (3) When the current position is not on the enforcement route, the control unit 11 operates with a sensitivity corresponding to the vehicle speed based on AAC / ASS.

[0211] For example, MSSS is a modulated wave in the K band. When the vehicle moves so as to approach MSSS, the electronic device 10 mounted on the vehicle receives radio waves in the K band, for example, at a distance (such as 300 m ahead) from a remote location. However, at the time of reception, modulation cannot be recognized, and in order to discriminate whether it is a predetermined modulated wave, the reception level of the received radio wave needs to be above a certain level.

[0212] Therefore, when the reception level of the radio wave is weak, the control unit 11 cannot accurately determine the modulation. Then, the control unit 11 travels after first receiving the radio wave, approaches the vehicle speed measuring device, and recognizes a predetermined modulation after the reception level increases. When performing control of the alarm type "accuracy", when the control unit 11 recognizes MSSS from the modulation state of the received radio wave and issues an alarm, for example, an alarm is issued for the first time when approaching about 100 m in front of MSSS. When the control unit 11 performs such alarm control, it cannot sound the alarm from a position far from MSSS, and the alarm sounds immediately before. Therefore, there is a possibility that the user may be delayed in applying the brakes and may not be mentally prepared.

[0213] When performing the control of (1), since the control unit 11 issues an alarm in accordance with the reception of radio waves in the K band, the user can know the possibility that enforcement using the portable orbis such as MSSS is being performed at a position relatively far from the portable orbis such as MSSS at the time of receiving the radio waves in the K band.

[0214] On the other hand, the place where enforcement is performed using a portable orbis such as MSSS is a place where traffic accidents are likely to occur. It is preferable that the user can recognize the existence of MSSS from a position relatively far from the deployment position of MSSS or the like, so that safe driving can be performed with a margin. For that purpose, it is preferable that the control unit 11 performs control to issue an alarm from a distant position as early as possible.

[0215] When performing the control of (2), the control unit 11 receives and notifies radio waves from an MSSS or the like from a farther distance. The user can recognize the possibility of its existence from a position farther away from the deployment position of the MSSS or the like in addition to the operation and effect of (1).

[0216] On the other hand, when the control unit 11 notifies an alarm regardless of the presence or absence of modulation as in (1) and (2) above, an alarm is also issued when receiving radio waves other than those of the MSSS, for example, K-band radio waves emitted from vending machines, automatic doors, or a collision prevention system installed in a Mazda vehicle. Therefore, when operating reactively, the electronic device 10 will have more false alarms notified.

[0217] When performing the control of (3), if the current position is not a restricted route, the control unit 11 operates with a sensitivity according to the vehicle speed based on the AAC / ASS. When driving on an ordinary road, the speed is often less than 60 km / h, and the control unit 11 operates in the city or extra mode. Therefore, the control unit 11 reduces the reception sensitivity to perform detection processing, making it difficult to receive radio waves from the MSSS and vending machines, etc., and reducing the frequency of alarms compared to when driving on a restricted route. Therefore, the user can reduce the annoyance of receiving alarms based on the reception of radio waves other than those of the MSSS, etc.

[0218] When operating in the super extra mode regardless of the vehicle speed, since the reception sensitivity is high, the control unit 11 can easily detect radio waves from vending machines, etc. Furthermore, it is also notified when temporarily stopped at a signal or driving at a low speed. Therefore, it may become a breeding ground for false alarms.

[0219] And in places other than restricted routes, it is highly likely that no enforcement using a portable orbis such as an MSSS is being carried out. Therefore, when the electronic device 10 receives K-band radio waves, it is highly likely that the radio waves are from devices and equipment other than portable orbis such as vending machines.

[0220] Therefore, the control unit 11 performs the control in (3) and switches the sensitivity based on the public security control information, thereby suppressing the occurrence of false alarms outside the control route.

[0221] Therefore, in the deployment prefectures such as MSSS, even if there are false alarms, in order to give an early notification when there is a possibility of the existence of MSSS, etc., the control unit 11 should operate the alarm type in a reactive manner. In addition, the control routes announced by the police can be said to be places where traffic accidents and the like are likely to occur and are dangerous. Therefore, reactivity can be said to be a mode in which it operates at the highest sensitivity in the dangerous places and at normal sensitivity in other places.

[0222] After the start of reception of the above radio wave, the control unit 11 may analyze the presence or absence of modulation, recognize whether it is a radio wave from a portable orbis such as MSSS, and perform a predetermined notification based on the recognition result. For example, when receiving a radio wave with an unknown modulation state, the control unit 11 issues an alarm notifying the reception of a radar wave regardless of the type of radar. Then, when it is later found to be MSSS, the control unit 11 issues an alarm for MSSS reception. In addition, when it is later found that the radio wave is unmodulated and not a portable orbis, the control unit 11 notifies that the previous notification was not due to MSSS and that it is the reception of a radio wave from a vending machine or the like, and ends the alarm. Also, the predetermined notification includes ending the notification without giving any notification.

[0223] In this way, the user can know whether the previous alarm based on the reception of the K-band radio wave was from a portable orbis such as MSSS or from something other than a portable orbis other than a vending machine or the like.

[0224] The above has been described by taking the case where the portable orbis is MSSS as an example, but the control for other portable orbis such as those using JMA is the same, and in the following description, the parts described as MSSS may also be replaced with descriptions such as JMA.

[0225] In addition to the enforcement route, the enforcement area is also disclosed in the disclosure enforcement information. In this embodiment, the target set to super extra is the enforcement route, but the enforcement area may also be added. When the enforcement area is added, the control unit 11 sets the sensitivity to super extra when the current position is within the enforcement area or on the enforcement route, and sets the sensitivity according to AAC / ASS at other locations. The enforcement area is wider in range than the enforcement route and there is a risk of frequent false alarms. Therefore, it is better to limit it to the enforcement route as in the above-described embodiment.

[0226] (6-5-2. Alarm type switching control based on deployment information) The full-auto function is a function that automatically selects the "alarm type" according to the portable Obis deployed for each prefectural police based on the current position. The electronic device 10 stores and holds the deployment status such as the presence or absence of the deployment of portable Obis such as MSSS and JMA for each prefecture in the storage unit 25, the storage medium 50, etc. The control unit 11 refers to the map data based on the current position information and recognizes the prefecture where it currently exists. When the current position is in a prefecture that deploys MSSS, JMA, etc., the control unit 11 internally sets the alarm type to "response", and when it is in a prefecture that does not deploy MSSS, etc., the control unit 11 internally sets the alarm type to "accuracy".

[0227] That is, when the current position enters the enforcement route in a prefecture that deploys MSSS, etc., the control unit 11 sets it to the highest sensitivity super extra. And when the control unit 11 receives a predetermined radio wave in the K band, it gives an alarm regardless of the presence or absence of modulation. Also, even in a prefecture where MSSS, etc. are deployed, when the current position is not on the enforcement route, the control unit 11 operates with a sensitivity according to the speed of AAC / ASS.

[0228] Thus, for example, when the vehicle is traveling in Hokkaido (an example of a prefecture where MSSS is deployed), the control unit 11 operates with the highest sensitivity on the enforcement route. And the control unit 11 receives and notifies the radar wave from the MSSS even at a far position away from the MSSS. Also, there are devices and equipment that emit K-band radio waves such as vending machines along the enforcement route. And when the control unit 11 of the electronic device 10 operating with the highest sensitivity receives the radio wave from a vending machine or the like, it issues an alarm based on the radar reception. And at this time, since the electronic device 10 is performing the detection process with the highest sensitivity, it is in a situation where it is also likely to issue an alarm based on the reception of the radio wave from a vending machine or the like. In this way, the electronic device 10 traveling on the enforcement route will have more alarms based on the reception of the radio wave from a vending machine or the like, but it can receive and notify the enforcement wave radio wave from the MSSS from a distance. On the other hand, even when traveling on a road other than the enforcement route in a prefecture where MSSS is deployed, the control unit 11 operates with a sensitivity according to the speed. Thereby, the occurrence of false alarms is reduced.

[0229] Also, for example, when the vehicle is traveling in Aichi Prefecture (an example of a prefecture where MSSS is not deployed), the control unit 11 alarms only when it receives radio waves from an MSSS or JMA with a specific modulation frequency, and the false alarms are reduced. Also, the control unit 11 does not switch to super extra even on the enforcement route in a prefecture where it is not deployed.

[0230] When receiving the K-band while the vehicle is traveling in a prefecture where a portable orbis using MSSS or other K-bands is not deployed, it is highly likely that the radio wave is emitted from sources other than portable orbis such as vending machines and automatic doors. Therefore, when the vehicle is traveling in such an undeployed area, if the control unit 11 operates the alarm type reactively, false alarms will occur frequently. Therefore, in such an area, it is better for the control unit 11 to operate the alarm type with accuracy. The control unit 11 operating with accuracy does not issue an alarm until it determines that the received radio wave is modulated. Therefore, the control unit 11 does not sound an alarm even when it receives the radio wave from a vending machine or the like.

[0231] Also, when the control unit 11 operates the alarm type accurately at a location where MSSS is deployed for some reason, if the control unit 11 determines that the received K-band radio wave is subject to a predetermined modulation, it issues a reception alarm for MSSS. Therefore, the user can recognize the presence of MSSS at a position before reaching a predetermined distance from MSSS and perform a predetermined driving operation or the like accordingly.

[0232] As described above, the function and effect of the alarm type "Full Auto" are that in the prefectures where portable orbits such as MSSS are deployed, the user can recognize the possibility of the presence of portable orbits from a distant position, and in the prefectures where portable orbits are not deployed, the occurrence of false alarms can be suppressed as much as possible. The electronic device 10 can perform appropriate operations for the user.

[0233] Furthermore, the alarm type "Full Auto" has the effect that by updating the data on the deployment status, the user can perform appropriate operations corresponding to the deployment status at that time even if they are not aware of the existence of prefectures where portable orbits such as MSSS are newly deployed. For example, currently, Aichi Prefecture does not deploy MSSS or the like, but it may be deployed in the future. If the alarm type "Full Auto" is turned on, the control unit 11 will, based on the information of the updated deployment status data, operate the alarm type in the "Responsiveness" setting when Aichi Prefecture becomes a deployed prefecture. Therefore, even if the user is not aware that it has become a deployed prefecture, the setting will be updated in the direction of sounding the alarm while driving in Aichi Prefecture.

[0234] <6-6. Alarm Function Using Icons> FIG. 24 shows an example of a standby screen displayed by the control unit 11 on the display unit 13. This standby screen displays a map around the current position. The control unit 11 accesses the map data stored in the storage unit 25 based on the current position information (latitude information and longitude information) acquired by the position information acquisition unit 17, reads out the surrounding map, and displays it on the display unit 13. The control unit 11 has a function of superimposing and displaying information acquired based on the current position information and vehicle speed and the like on the map displayed on the display unit 13.

[0235] The control unit 11 displays a vehicle icon 51 indicating the vehicle position at the position on the map corresponding to the current position. The control unit 11 displays the current place name acquired from the map data based on the current position in the first display unit 131 at the upper left of the display unit 13. Further, the control unit 11 displays the current time acquired from the clock unit 113 in the second display unit 132 arranged below the first display unit 131. The control unit 11 displays the current road name acquired from the map data based on the current position in the third display unit 133 at the upper right of the display unit 13. The control unit 11 displays the acquired current vehicle speed in the fourth display unit 134 arranged below the third display unit 133.

[0236] Furthermore, in the present embodiment, the control unit 11 displays an RD icon 52 indicating the current operation mode of radar reception below the fourth display unit 134. Further, when the warning type is operating in a reactive state and a portable orbis is deployed in the current prefecture, the control unit 11 displays an orbis name icon 53 identifying the portable orbis below the RD icon 52.

[0237] (6-6-1. Warning function using RD icon) As shown in Fig. 25(A), nine RD icons 52 are prepared. The image diagram of this RD icon 52 is stored in the storage unit 25, for example, and the control unit 11 reads out the corresponding image diagram according to the current setting status and displays it at a predetermined position. The relationship between the setting status such as sensitivity and the RD icon 52 and the warning process performed at that time are as follows.

[0238] The icon with [OFF] written at the top is the icon displayed when the radar warning setting is turned off based on an operation on a setting menu (not shown). In this state, the radar reception-based warning does nothing. For example, when the user feels that there has been no warning based on radar reception recently, the user can check the display of this RD icon 52 and confirm that if [OFF] is displayed, the OFF setting is made and there is no failure.

[0239] The icon with the second [-] is the icon to be displayed when AAC is in the prohibited state. AAC is a function that does not give an alarm when the vehicle speed is below a certain speed. When AAC is effective, for example, when the vehicle stops while waiting for a signal or is running at a low speed due to traffic congestion, etc., even if the control unit 11 receives radio waves, it does not give an alarm. The control unit 11 displays this icon when the current setting is that AAC is in the prohibited state.

[0240] In the description in the column of "6-3. Full Auto [MSSS] Function", the certain speed at which no alarm is given using AAC was set at 30 km / h. However, it may be set to a lower speed, for example, 20 km / h. For example, in areas such as Zone 30 where the speed limit is 30 km / h, portable orbis are used for enforcement. Therefore, if no alarm is given when the vehicle speed is 30 km / h or less, when driving in compliance with the speed limit, even if radio waves from the above portable orbis are received, no alarm will be given, which is not preferable. Therefore, by lowering the speed at which the alarm starts to 20 km / h, the situation where no alarm is given can be suppressed. Note that the certain speed at which no alarm is given is an example of 20 km / h, and appropriate values can be taken. However, if it is lowered too much, the effect of AAC will decrease, so it is advisable to determine it considering the speed limit of the place where the portable orbis is installed. For example, when enforcement is carried out at 20 km / h, for example, an alarm may be sounded when the speed is 15 km / h or more, and no alarm may be sounded when the speed is less than 15 km / h. Also, the certain speed at which no alarm is given may be set slightly lower than the conventional 30 km / h, for example, 25 km / h. In such a setting, even on a road with a speed limit of 30 km / h, the frequent occurrence of alarms during low-speed driving where the speed does not exceed less than 25 km / h can be suppressed. And when driving at 25 km / h or more within the speed limit, since there is a risk of exceeding the speed when slightly stepping on the accelerator, by sounding an alarm at 25 km / h or more, the presence of a portable orbis or the like can be notified from a distance. In the setting where no alarm is sounded, the presence of a portable orbis or the like cannot be known, and when the alarm sounds, the situation is already too late. By making the above various settings, the occurrence of such a situation can be prevented.

[0241] The icon with the third [C] is the icon displayed when set to City by manual operation. This icon shows "C" in red characters with a white border, and the background color uses a darker shade of the same red color. City is a mode where when receiving weak radio waves, it gives notifications using the screen but does not sound an alarm. When set to this City, the control unit 11 controls not to sound an alarm even when receiving microwaves at reception levels 1 and 2. For example, in an urban area or the like, when repeatedly driving / stopping at low speeds and the control unit 11 sounds an alarm based on the reception of radio waves from a vending machine or the like, the user may feel bothered. Such users who feel bothered will be relieved of the annoyance because the alarm will not sound when set to City. Also, the control unit 11 controls to sound an alarm when receiving microwaves at reception level 3 or higher.

[0242] The icon with the fourth [E] is the icon displayed when set to Extra by manual operation. This icon shows "E" in green characters with a white border, and the background color uses a darker shade of the same green color. Extra is a mode that makes it easier to sound an alarm than City. When set to this Extra, the control unit 11 controls not to sound an alarm even when receiving a microwave at reception level 1. The control unit 11 controls to sound an alarm when receiving microwaves at reception level 2 or higher.

[0243] The icon with the fifth [SE] is the icon displayed when set to Super Extra by manual operation. This icon shows "SE" in blue characters with a white border, and the background color uses a darker shade of the same blue color. Super Extra is a mode that sounds an alarm when receiving a predetermined microwave. The control unit 11 controls to sound an alarm even when receiving a microwave at level 1.

[0244] The icon with the 6th [C] is the icon that is displayed when it becomes the city when set to AAC / ASS. This icon shows "C" in white text on a red background color. ASS changes the reception sensitivity according to the vehicle speed. It operates together with AAC, and when the speed is less than a certain speed, for example, less than 20 km / h, no alarm is given by AAC, and it becomes the city when it is between 20 km / h and less than 40 km / h. The operation in the city when set to AAC / ASS is the same as when set to the city by the above-described manual operation.

[0245] The icon with the 7th [E] is the icon that is displayed when it becomes the extra when set to AAC / ASS. This icon shows "E" in white text on a green background color. It becomes the extra when the speed is between 40 km / h and less than 60 km / h. The operation in the extra when set to AAC / ASS is the same as when set to the extra by the above-described manual operation. Also, the upper limit may be set to less than 80 km / h assuming a highway.

[0246] The icon with the 8th [SE] is the icon that is displayed when it becomes the super extra when set to AAC / ASS. This icon shows "SE" in white text on a blue background color. It becomes the super extra when the vehicle speed exceeds the upper limit of the extra. The operation in the super extra when set to AAC / ASS is the same as when set to the super extra by the above-described manual operation.

[0247] The icon showing the 9th [SE] is an icon that is displayed when the full-auto mode is ON and the current position enters the restricted route and becomes Super Extra as described in "6-5. Alarm Type "Full-Auto" Function". This icon uses a blue background color like the 8th icon and shows "SE" in red characters. In this way, by changing from white characters to colored characters, the display mode of the prominent icon can be achieved. Furthermore, by using red-based colors, the user can intuitively understand that the situation is urgent and dangerous. Additionally, the characters of the 3rd icon displayed when setting the city based on manual operation are also red, but this icon uses a brighter color than the red used for the 3rd icon. In other words, the color of the character C of the 3rd icon may use a slightly duller red.

[0248] When it becomes Super Extra when this full-auto is ON, the alarm operation is the same as the alarm operation when it becomes Super Extra based on the 8th speed. However, the conditions for becoming Super Extra are different. The control unit 11 sets it to Super Extra regardless of the vehicle speed when entering the restricted route and displays this 9th icon at a predetermined position on the display unit 13. Since it has a more prominent display mode than the 8th icon that became Super Extra based on speed as described above, the user can easily recognize that the 9th icon is displayed as the RD icon 52.

[0249] In this way, the control unit 11 displays the RD icon 52 indicating the current sensitivity setting mode, etc. Therefore, the user can know in which reception sensitivity (City Extra, Super Extra) the electronic device 10 is currently operating.

[0250] Also, the sensitivity change based on AAC / ASS changes step by step as "City → Extra → Super Extra", and the control unit 11 sequentially switches the display of the RD icon 52. On the other hand, when full auto is on, the control unit 11 immediately switches to Super Extra as it enters the restricted route, and the RD icon 52 also displays a special icon, emphasizing that it has entered the restricted route. Accordingly, the user can understand that they are currently driving on the most dangerous route.

[0251] Also, the Super Extra when set to AAC / ASS switches, for example, at a speed of 60 km / h or more, so it often stops at Extra while driving on a general road. If the sensitivity switches to Super Extra while driving on a general road, it means that the speed limit has been exceeded. When the user recognizes that the RD icon 52 is the Super Extra icon when set to the 8th AAC / ASS, they can intuitively understand that they have exceeded the speed limit and can decelerate to drive safely.

[0252] The control unit 11 may operate according to the flowchart shown in FIG. 26, for example, and perform the above-described display control of the RD icon 52. That is, the control unit 11 checks whether the radar alarm setting is OFF (S1). If it is OFF (S1 is Yes), the control unit 11 displays the RD icon with the alarm setting OFF (the first one in FIG. 25(A)) (S2). After executing the display process of this RD icon with the alarm setting OFF, the control unit 11 returns to process step 1 and checks whether the radar alarm setting is OFF.

[0253] When the radar alarm setting is ON (S1 is No), the control unit 11 checks whether AAC is set to the prohibited state (S3). If it is in the prohibited state (S3 is Yes), the control unit 11 displays the RD icon in the AAC prohibited state (the second one in FIG. 25(A)) (S4). After executing the display process of this RD icon in the AAC prohibited state, the control unit 11 returns to process step 1 and checks whether the radar alarm setting is OFF.

[0254] When AAC is not in the prohibited state (S3 is No), the control unit 11 checks whether the reception sensitivity setting is a manual setting or an AAC / ASS setting (S5). When it is a manual setting, the control unit 11 displays the RD icon (any one of the 3rd to 5th from the top in Fig. 25(A)) corresponding to the sensitivity (either city, extra, or super extra) set manually (S6). After the control unit 11 executes the display process of the RD icon corresponding to this manual-based sensitivity, it returns to process step 1 and checks whether the radar alarm setting is OFF.

[0255] If the sensitivity setting is an AAC / ASS setting in the branch determination of process step 5, the control unit 11 checks whether the alarm type is set to full auto ON (S7). When full auto is not ON (S7 is No), the control unit 11 acquires the current vehicle speed (S8). Then the control unit 11 displays the RD icon (any one of the 6th to 8th from the top in Fig. 25(A)) corresponding to the sensitivity (either city, extra, or super extra) according to the acquired vehicle speed (S9). After the control unit 11 executes the display process of the RD icon corresponding to this vehicle-speed-based sensitivity, it returns to process step 1 and checks whether the radar alarm setting is OFF.

[0256] On the other hand, when full auto is ON, the control unit 11 determines whether the current location is in a deployment prefecture such as MSSS (S10). When it is not in a deployment prefecture such as MSSS (No in S10), the control unit 11 jumps to process step 8 and acquires the vehicle speed. Also, when it is in a deployment prefecture such as MSSS (Yes in S10), the control unit 11 determines whether the current position is on a restricted route (S11). When it is not on a restricted route (No in S11), the control unit 11 jumps to process step 8 and acquires the vehicle speed. When it is on a restricted route (Yes in S11), the control unit 11 displays the RD icon for full-auto super extra (the 9th from the top in Fig. 25(A)) (S12). After the control unit 11 executes the display process of this super extra RD icon, it returns to process step 1 and checks whether the radar alarm setting is OFF.

[0257] The control unit 11 repeatedly executes the above-described processing and displays the RD icon 52 corresponding to the setting status at that time. Therefore, for example, when AAC / ASS is set and full auto is ON, when entering a regulatory route, the RD icon 52 of [SE] in red characters is immediately displayed. When not in a regulatory route, the RD icon displayed as the speed increases does not go from white characters of [C], then white characters of [E], and finally red characters of [SE], but becomes white [SE].

[0258] Also, FIG. 26 is an example. For example, the control unit 11 may be configured to be executed in various control processes such as operating in parallel in a multitask.

[0259] (6-6-2. Alarm function using the Obis name icon) As shown in FIG. 25(B), four Obis name icons 53 are prepared. Each Obis name icon 53 uses a picture with an orange background color and shows an abbreviation using an alphabet that identifies the type of portable Obis in white characters. In the illustrated example, [MSSS], [JMA], [LSM], and [~] are displayed in order from the top. The icon with [~] described in the fourth position is an icon used when the type is unknown. An image diagram of this Obis name icon 53 is stored and held in the storage unit 25, for example. The control unit 11 reads out the corresponding image diagram according to the deployment status of the portable Obis in the prefecture where the current position is located and displays it at a predetermined position (below the RD icon 52) in the display unit 13.

[0260] When the alarm type is reactive, the control unit 11 accesses the storage unit 25, checks the deployment status of the portable Obis in the prefecture where it is currently located, and identifies the type of the portable Obis if it is deployed. Then, the control unit 11 causes the storage unit 25 to read out the Obis name icon 53 corresponding to the identified type of portable Obis and displays it at a predetermined position in the display unit 13.

[0261] The electronic device 10 of this embodiment will display the name of the local portable orbis in the prefecture where the portable orbis is deployed. Based on the presence or absence of the display of the orbis name icon 53, the user can know whether a portable orbis is deployed in the area where the vehicle is currently traveling. For example, when driving with full auto ON, the control unit 11 performs control to display one of the orbis name icons 53 in the prefecture where the portable orbis is deployed and not to display the orbis name icon 53 in the non-deployed prefecture. Therefore, the user can know whether a portable orbis such as MSSS is deployed in the current prefecture, and it may give a feeling of switching.

[0262] In this embodiment, the type of the deployed portable orbis is notified using the orbis name icon 53. However, instead of or in addition to this function, it is preferable to have a function of displaying characters / text at a predetermined position on the display unit 13. For example, the control unit 11 may display "MSSS available", "JMA available", etc. beside the current place name displayed on the first display unit 131.

[0263] (6-6-3. Processing when full auto is ON and the sensitivity is set manually) As described above, the full auto function is a function that automatically selects an "alarm type" according to the portable orbis deployed for each prefectural police based on the current position. And the control unit 11 switches the alarm type between the settings of "reactivity" and "accuracy" according to the deployment status of the portable orbis in the prefecture of the current position. When the current position is in a deployed prefecture, if AAC / ASS is set, the control unit 11 has a function of switching the sensitivity according to the speed and further setting the highest sensitivity on the traffic control route.

[0264] On the one hand, when the sensitivity is set to either City, Extra, or Super Extra manually, the control unit 11 gives priority to the manual setting over the full-auto setting even if the full-auto is ON. When entering a restricted route, it does not automatically switch to Super Extra but remains set as per the original manual setting. By doing so, the electronic device 10 can operate at the sensitivity intended by the user.

[0265] Also, when the full-auto is ON, the control unit 11 gives priority to the manual setting for sensitivity, but it may switch the alarm type between reactivity and accuracy according to the deployment status of the portable orbis. In this way, in the prefectures where the portable orbis is deployed, the control unit 11 can give an alarm from a relatively far position when the portable orbis is deployed. Note that how far in advance to give the alarm follows the sensitivity set manually. On the other hand, in the prefectures where the portable orbis is not deployed, no alarm based on the reception of radio waves from vending machines, etc. is given, and the occurrence of false alarms can be suppressed as much as possible.

[0266] In this way, for example, by turning on the full-auto, it is possible to appropriately operate in each of the deployed and non-deployed prefectures for the conflicting issues of detecting and notifying the presence of the portable orbis early and suppressing false alarms. Furthermore, even when the full-auto is turned on or when the sensitivity is set manually, the AAS does not operate, and an alarm based on radar reception can be sounded even during low-speed driving or temporary stops.

[0267] Also, the frequency of false alarms that cause annoyance varies from person to person. Some users may think that it is okay to have some false alarms but want to be able to detect and notify the portable orbis reliably. Also, in such cases, there are users who want to know that there may be a portable orbis present from a farther distance. Or conversely, there are users who want to avoid false alarm notifications as much as possible.

[0268] Therefore, in this embodiment, as described above, there are functions that can switch sensitivity manually and by speed, functions that can automatically switch sensitivity according to manual and speed, and functions that can automatically switch the alarm type according to the deployment status of the portable orbis. By performing these switches, a large number of combinations are made possible. As a result, the electronic device 10 can be configured to perform operations that meet the conditions for issuing an alarm desired by each user.

[0269] (6-6-4. Approach Notification of the Regulatory Route) As described above, when the alarm type is reactive and the host vehicle is located on the regulatory route during operation, the control unit 11 controls to set the sensitivity to the highest sensitivity of super extra and display the corresponding RD icon 52. Instead of or in addition to this function, the control unit 11 may be provided with a function of changing the display mode of the map when entering the regulatory route. In this way, the electronic device 10 can use the change in the display mode of the map to convey that it has entered the regulatory route from outside the regulatory route. The user can visually recognize this change in the display mode and recognize that they have entered the regulatory route.

[0270] The change in the display mode of the map may be, for example, that the control unit 11 displays the entire map in monotone, changes the brightness, or overlays and draws a predetermined color such as red over the entire screen. The control unit 11 may perform a process of returning to the display of the map on the original color screen after a predetermined time, for example, 1 second or several seconds. Also, instead of changing the entire display of the map in this way, the control unit 11 may perform a display of bordering the outer periphery of the display area of the map with a predetermined color, for example, red. No matter which of these changes in the display mode is made, since the entire display screen of the display unit 13 changes, the user can easily recognize the change. For example, a user during driving often looks outside the vehicle such as in the front, and the frequency of gazing at the display unit 13 is low. When the entire screen changes as in this embodiment, the change enters a part of the user's field of vision, and the user can easily notice the change.

[0271] Also, when the control unit 11 detects that it has entered a restricted route based on the current position information and the map data, it displays the restriction information about that route on the fifth display unit 135 that displays a character message provided at a predetermined position on the display unit 13. The control unit 11 periodically determines whether the current position is on the restricted route based on the current position information. When the previous processing result is outside the restricted route and the current processing result is on the restricted route, the control unit 11 recognizes that it has entered the restricted route. Then, the control unit 11 may read out the restriction information (for example, "Route ○○ is restricted from when to when") stored in association with the entered restricted route and display it on the fifth display unit 135 (see Fig. 27). Also, when displaying the restriction information, the control unit 11 may scroll and display the restriction information about that route in text like a news flash. Further, when in a prefecture where a specific portable orbis such as MSSS is deployed, for example, in addition to or instead of the above restriction information, the control unit 11 may textually display a message such as "Attention to MSSS" to emphasize that it is a dangerous route where MSSS etc. are deployed.

[0272] <6-7. Telop display function in the deployment prefecture> The control unit 11 has a function of notifying that it has entered the prefecture where the portable orbis is deployed. The notification may be, for example, to display a window with a message such as deployment information (for example, "MSSS is deployed from here") over the waiting screen such as a map. Also, when the control unit 11 enters a prefecture where the portable orbis is not deployed, it may notify that it is a non-deployed prefecture, or it may not notify that it is a non-deployed prefecture. In particular, the control unit 11 may not notify in the case of a non-deployed prefecture and only notify that it is the prefecture where the portable orbis is deployed when entering the prefecture where the portable orbis is deployed. Thereby, when the user receives a notification regarding the deployment status at the prefecture border, the user can understand that they have entered the deployed prefecture without checking the content.

[0273] When the control unit 11 recognizes that it has passed the prefectural border of a prefecture based on the current position information, it determines whether the current prefecture it has entered is a prefecture where the portable orbis is deployed. Then, in the case of a deployed prefecture, the control unit 11 displays a message on the display unit 13 so that it can be known that it is a deployed prefecture. Also, the message indicating that it is a deployed prefecture may not describe a specific orbis name, such as "This is a prefecture where the portable orbis is deployed" or "Caution: Portable orbis", and it may be better to specify the type of the deployed portable orbis and give a notification based on that type.

[0274] Also, in the above-described embodiment, when full auto is turned on, the sensitivity is increased at specific positions such as the restricted route, but when the function of outputting a message for notifying deployment information is provided as in this embodiment, the control unit 11 may not change the sensitivity based on the full auto function. As one of the controls using deployment information such as MSSS, it is advisable to notify the deployment information at an appropriate timing such as when entering a deployed prefecture. The control unit 11 may not only display a message but also use the function of changing the sensitivity described above in combination.

[0275] <6-8. Data update function for the deployment status of the alarm type "Full Auto">

[0276] (6-8-1. Utilize the update of public enforcement information) As described above, the deployment status of MSSS is stored in the header part of the public enforcement information. As a result, a user who regularly updates the public enforcement information also has the deployment status updated to the latest one at the same time, and alarm processing according to the actual deployment status is performed. Also, the file of the public enforcement information may store the content at the time of shipment. By doing so, the deployment status at the time of shipment is stored in the header part. Therefore, alarm control according to the deployment status at that time is performed. Also, once MSSS is deployed, it is less likely to become undeployed thereafter. Therefore, in the prefecture where it is deployed at the time of shipment, for example, an alarm can be notified based on the detection of MSSS from a distance, and the frequent occurrence of false alarms in non-deployed prefectures can also be suppressed.

[0277] Furthermore, the deployment information in the alarm type "Full Auto" targets portable orbis such as JMA in addition to MSSS. For the installation status of each portable orbis, for example, it is advisable to set deployment / non-deployment for each type of portable orbis. By doing so, for example, "MSSS deployed = 1, MSSS not deployed = 0" is 1 bit, and "JMA deployed = 1, JMA not deployed = 0" is 1 bit, and it can be stored by allocating 1 bit each. This deployment status may be allocated, for example, to a predetermined 1 byte in the header section. By allocating 1 byte, it becomes possible to handle cases where, for example, the types of orbis for registering the deployment status increase, such as new types or laser-type orbis.

[0278] Since the deployment information is registered in the header section of the public regulation information in this way, when the update process of the public regulation information is performed, it is stored in a predetermined storage area of the electronic device 10 together with the header section, and the update registration of the deployment status is automatically completed. The control unit 11 of the electronic device 10 checks the header section of this public regulation information, recognizes the deployment status at the current position, and performs predetermined control.

[0279] The update process of the public regulation information accesses, for example, a server storing the public regulation information via the Internet using a personal computer or the like with the storage medium 50 set, and saves the latest public regulation information in the storage medium 50. The user takes out the storage medium 50 from the personal computer and sets the taken-out storage medium 50 in the mounting unit 21. As a result, when the control unit 11 directly views the public regulation information stored in the storage medium 50, for example, the update process ends since the storage medium 50 is set in the mounting unit 21. Further, when the control unit 11 accesses the storage unit 25 to check deployment information or the like, the control unit 11 that recognizes that the storage medium 50 is set in the mounting unit 21 accesses the storage medium 50, and checks whether the public regulation information stored in the storage medium 50 is updated compared to that stored in the storage unit 25. If it is updated, the data is stored in the storage unit 25 and the update process ends. If it is not updated, the control unit 11 does not rewrite the storage unit 25. By doing so, it is possible to suppress the rewriting to old information and the deviation between the actual deployment status and the stored deployment status data, and to perform the alarm process in an appropriate mode.

[0280] Whether it is updated or not may be managed by, for example, the update date or version number of the data, and it may be determined by the old and new of the regulation date or the like stored in the public regulation information. Further, the control unit 11 may check the area for registering the deployment status of the header unit and perform a process of setting the corresponding area of the storage unit 25 to deployment (1) in the case of deployment (1). Since it is generally unlikely that the portable orbis becomes un-deployed (0) after being deployed, as described above, by performing a process of overwriting the corresponding area of the storage unit 25 when the deployment status registered in the storage medium 50 is "deployed", the process can be performed without determining whether it is updated or not.

[0281] Also, the deployment status of the portable orbis is information by prefecture, and the public regulation information is also information by prefecture. In this way, it is preferable to store the same update information together with the area unit for registering the deployment status.

[0282] Also, when there are paid update information and free update information, the deployment status of the portable orbis may be provided together with the free update information. When providing a free update of the public regulation information, the deployment status of the portable orbis may be registered in the header part of the public regulation information and provided together. Conversely, it may be registered and provided together with the paid update information.

[0283] On the other hand, when the deployment status of the portable orbis is registered by prefecture, it will be 47 pieces and 47 sets of data. Compared with other update information, the data volume is small, and only one extremely small file is required. And the update information of the deployment status of the portable orbis may be allowed to be downloaded alone. If it is allowed to be downloaded alone, the number and types of update processes will increase, making it cumbersome, and the possibility of forgetting to update some information will also increase.

[0284] As described above, the public regulation information has the area, range, or region where the information becomes effective coincide with the deployment status of the portable orbis, and because the data volume of the deployment status of the portable orbis is small, it can be placed in the header part. The public regulation information is updated frequently, for example, daily. Users who use the public regulation information perform update processes frequently. Since the update process is performed frequently in this way, the possibility of forgetting to update is suppressed as much as possible, and the deployment status also reflects the latest one and can be provided to users. The deployment status may be configured to be sent together with those with a high update frequency.

[0285] (6-8-2. Utilization of Updates of Multiple Update Information) Also, the deployment status of the portable orbis may be stored together with other update information, for example, POI information used for GPS alerts, information such as pictures, CGs, and photos displayed on the alert screen, and update files of firmware and other systems. And the same update data of the deployment status may be registered in each of multiple types of update information.

[0286] When the update data with the same deployment status is registered together in a plurality of pieces of update information, when the update process for any of the pieces of update information is executed, the electronic device 10 can update the deployment status. For example, the electronic device 10 of a user who does not download the public enforcement information remains in the deployment status stored at the time of shipment, which may be different from the actual operation. However, by performing the update process for any of the pieces of update information, the possibility of updating the deployment status is increased.

[0287] Also, when registering the update data with the same deployment status in a plurality of pieces of update information, the control unit 11 checks the old and new of the deployment status stored in a predetermined storage area of the storage unit 25 against the update data of the deployment status acquired this time. When the deployment status acquired this time is new, a process of rewriting that storage area with the deployment status acquired this time may be performed. Then, when the control unit 11 issues an alarm associated with radar reception, it checks the deployment status stored in a predetermined storage area of the storage unit 25 and executes a predetermined process. The data of the deployment status stored in the predetermined storage area may be, for example, a file of deployment information for each prefecture, and reading and writing may be performed on that file.

[0288] Alternatively, the control unit 11 may be provided with a function of reading out the data of the deployment status stored together and rewriting the header part of the public enforcement information based on the read information whenever any update process is performed.

[0289] (6-8-3. Using Manual and Other Submission Information) In each of the above-described embodiments, the update process can be automatically performed by downloading the update information or obtaining the storage medium 50 in which the update information is stored. Furthermore, together with or instead of this function, a function for manual setting may be provided.

[0290] The function of manual setting may be, for example, to prepare a setting screen for each prefecture. Each setting screen may display the name of the prefecture on the upper end side or the left end side, etc., and include the display of the name of the portable orbis to be set (such as MSSS, JMA, etc.) and a column for registering the deployment status adjacent to the name. The initial value of the column for registering the deployment status may be, for example, unregistered (deployment / undeployment unknown). And when the control unit 11 receives that a predetermined position has been touched or the like, it may switch to deployment.

[0291] Also, instead of manually inputting for all prefectures, for example, when the control unit 11 detects an operation on the screen touch or a separately prepared registration button, it may output and display a message prompting the registration of MSSS, such as "Do you want to set the current position as the MSSS deployment prefecture?". When the control unit 11 receives an instruction of Yes from the user, it may detect the current prefecture based on the GPS information and the map data, and update the data of the deployment status for the detected prefecture. Also, when an instruction of Yes is received, a screen for specifying the type of the portable orbis may be displayed, and the registration may be performed with the type of the portable orbis also specified.

[0292] When the control unit 11 manually registers the deployment status, for example, it sets a manually registered flag. This manually registered flag may be set for each prefecture. And the control unit 11 performs control not to perform automatic update for the prefecture with the manually registered flag set. By doing so, for example, it is possible to suppress as much as possible the situation where the latest information registered by the user after actually seeing the portable orbis is rewritten with old information.

[0293] For the control that does not perform automatic update, for example, when updating the data in the storage unit 25 based on the update information stored in the storage medium 50, it is advisable not to rewrite the deployment information for the prefectures where the manually registered flag is set. Also, when using the publicly enforced information registered in the storage medium 50 as it is, for example, separately store and hold the deployment information for the prefectures where the manually registered flag is set, and the control unit 11 may perform a process of rewriting the data on the deployment status in the header part of the publicly enforced information to the separately stored and held content.

[0294] The control that does not perform automatic update does not necessarily mean that it is not actually performed. For example, an update may be performed, but the updated information may not be used or may be treated as invalid. For example, prepare a separate file for manual registration of the deployment status, register the deployment status based on manual operation in that file, and also register the deployment status by automatic update as it is. Then, when the control unit 11 performs control based on the deployment status, if the manually registered flag is set, it uses the deployment status stored in the manual registration file, and if the flag is not set, it uses the deployment status updated automatically.

[0295] Also, by providing a manually registered flag for each prefecture as described above, it is possible to update the deployment status to the latest one by automatic registration for the prefectures that have not been registered. As a result, the user can operate in the latest deployment status based on the content actually seen and confirmed in places where the user can know the deployment status of the portable orbis, such as the location of their home or places they often visit. Also, for prefectures that are not often visited, it can be operated based on the latest deployment status prepared by the manufacturer or the like based on information announced by the police and automatically updated.

[0296] Also, manual registration should be allowed to register even non - deployment. By setting non - deployment, false alarms can be suppressed as much as possible.

[0297] Retain both the data of the manually registered deployment status and the data of the deployment status based on automatic update. The control unit 11 preferably has a function of comparing the registered deployment statuses respectively, presenting the information of the inconsistency when there is an inconsistency, and allowing the user to select which one to make effective. For example, the control unit 11 may ask, such as "It is not deployed (0) in the automatic update, but it is deployed (1) in your setting. Is that okay?", and make either information effective according to the user's judgment.

[0298] Also, since it rarely changes from deployed (1) to not deployed (0), for example, when the automatic update is deployed (1) and the manual registration is not deployed (0), it is advisable to confirm whether it is okay to operate with the non-deployment of the manual registration. Also, it is advisable to give priority to the manual registration and give priority to the ones where the deployment (1) is set.

[0299] (6-8-4. Notification Function for the Updated Deployment Status) When the control unit 11 downloads the public security control information, that is, when the public security control information is updated, it preferably has a function of displaying a message to confirm whether to turn on the full-auto function and changing the setting based on the instruction from the user. Useful information such as the deployment status of the portable orbis is registered in the header part of the public security control information, and it is possible to confirm with the user whether to use that information.

[0300] Also, for example, when it is possible to know from the deployment status of the updated data which prefectures have newly been deployed this time, the control unit 11 preferably has a function of notifying the newly deployed prefectures. For example, the control unit 11 may notify, such as "MSSS has newly been deployed in ○○ Prefecture" and "JMA has newly been deployed in △△ Prefecture", using voice or text.

[0301] By doing so, for example, the user can know that the current location or the areas frequently visited have become the deployed prefectures. Also, in the prefectures that have newly become the deployed prefectures, when operating with the full-auto turned on, the conditions for issuing an alarm are different, and it is possible to know in advance that the orbis alarm will be received more frequently than before.

[0302] For example, when the public security information stored in the storage medium 50 is stored in the corresponding area of the storage unit 25, it is possible to identify from the difference by comparing the deployment status for each prefecture registered in the header part of the registration information before the storage, that is, the previous public security information, and the deployment status for each prefecture registered in the header part of the public security information stored in the storage medium 50.

[0303] In addition, when the control unit 11 accesses the storage medium 50, checks the public security information stored in the storage medium 50, and performs predetermined control, the control unit 11 reads out at least the information regarding the deployment status when newly updated and stores and holds it in the storage unit 25. Then, it may be configured to recognize by comparing the stored and held information with the header part.

[0304] Also, in the new file, store and hold update information such as the date of update and the date of update. If the date is quite close to the current date in the past (for example, within the past month), it may be regarded as a newly deployed prefecture and the prefecture may be notified.

[0305] <6-9. Control at a level smaller than prefectures> The range of the area for registering the deployment status of the portable ORBIS stored in the storage unit 25 may be a more finely divided range narrower than the prefecture level. By doing so, the control unit 11 can perform control of alarms and notifications according to the deployment status for each more finely divided and narrower area than the prefecture level.

[0306] For example, at the time of filing this application, Hokkaido is designated as a prefecture where MSSS is deployed, but enforcement using MSSS is not necessarily carried out throughout Hokkaido. Even if MSSS is used in some areas of Hokkaido and not used in the remaining areas, the entire Hokkaido is considered a prefecture where MSSS is deployed. Then, even when the current position is traveling in the remaining areas within Hokkaido, if the full auto is on, the control unit 11 sets the alarm type to responsiveness and performs alarm control. Therefore, a situation where false alarms occur frequently is caused. On the other hand, if the deployment status is registered in a subdivided range as in this embodiment, it is possible to set some of the above-mentioned areas as MSSS deployed and the remaining areas as non-MSSS deployed. Therefore, when the current position is in the remaining areas, the control unit 11 can suppress the occurrence of false alarms by setting the alarm type to accuracy.

[0307] The subdivided range is preferably, for example, the range of municipalities, and particularly preferably the jurisdiction unit of the police. Also, the subdivided range may be in units of roads. In the case of road units, for example, based on past performance, roads that have been used may be set as deployed and roads that have never been used may be set as non-deployed.

[0308] [7.RD-related setting menu] <7-1. First method> The electronic device 10 equipped with the "6-3. Full auto [MSSS] function" may be provided with a false alarm reduction switch for setting ON / OFF of false alarm reduction. This false alarm reduction switch may be a mechanical switch or a soft button displayed on the display unit 13. This false alarm reduction switch may be switched ON / OFF by user operation regardless of the deployment status of MSSS, separately from the above-mentioned full auto [MSSS] function. When the false alarm reduction switch is configured by a soft button, it may be implemented, for example, as an item in the radar-related setting menu as shown below.

[0309] The electronic device 10 has a setting screen for receiving and warning of radar waves. The setting screen may arrange the four items of "X-band warning (ON·OFF)", "K-band warning (ON·OFF)", "false alarm reduction (ON·OFF)", and "full auto [MSSS] (ON·OFF)" in a row. The four items may all be composed of soft buttons and may be configured so that each can be independently set to ON or OFF.

[0310] Also, as shown in FIG. 28, "receiving sensitivity", "false alarm reduction", and "full auto MSSS" may be arranged so that each can be set. The receiving sensitivity shows an example where AAC / ASS is set in the illustrated example. When the area of the item is touched from this state, it switches to manual. Also, when three or more receiving sensitivities are prepared, the selected item may be switched each time it is touched in a toggle manner. The receiving sensitivities that can be manually selected are three: city, extra, and super extra. For example, as the item of "receiving sensitivity" shown in FIG. 28, "AAC / ASS", "city (manual)", "extra (manual)", "super extra (manual)", etc. may be prepared and switched in a toggle manner. Also, in this setting screen, "manual" may be selected, and city, extra, and super extra may be selectable in the lower setting screen when "manual" is selected, and various selection methods may be available. Also, when there are three or more options, instead of the toggle method, when an item is touched, the related lower setting screen may be displayed and made selectable.

[0311] Also, when full auto MSSS is ON, it may not be possible to use it in combination with the ON / OFF function of false alarm reduction based on manual operation. When full auto MSSS is ON, the control unit 11 operates in the same way as when false alarm reduction is OFF when the current position is where MSSS is deployed, and operates in the same way as when false alarm reduction is ON when the current position is where MSSS is not deployed. Therefore, when full auto MSSS is set to ON, the user's intention is to give an alarm according to the deployment status of MSSS.

[0312] When the full-auto MSSS is turned on, the control unit 11 invalidates the setting based on the false alarm reduction switch and performs an alarm operation based on the current position and the deployment status of the MSSS. Further, when the item of the full-auto MSSS is turned on, the control unit 11 may disable the operation of the "false alarm reduction" setting item and disable the manual ON / OFF switching. In this case, it is preferable to make it understood that the "false alarm reduction" item cannot be selected, for example, by being displayed in gray. In this way, the user can understand that the ON / OFF instruction by the "false alarm reduction switch" cannot be performed. Further, when the full-auto MSSS is turned off, the control unit 11 cancels the gray display and returns it to the same state as others, so that the "false alarm reduction" setting can be performed.

[0313] The initial value of the full-auto MSSS is preferably set to ON. By turning on the full-auto MSSS, the presence of the MSSS can be notified from a distance in the prefectures where the MSSS is deployed, the occurrence of false alarms can be suppressed as much as possible in the prefectures where the MSSS is not deployed, and appropriate information can be provided to the user. By setting the initial value to ON, it becomes an appropriate operation for the user.

[0314] <7-2. Second method> Figs. 29 and 30 show an example of a selection screen in the "6-5. Alarm type "full-auto" function". As shown in Figs. 29(A) and 30(A), a layout is adopted in which "reception sensitivity" and "alarm type" are arranged on one surface of the radar setting items. The reception sensitivity is an item for setting each mode of AAC / ASS and manual, similar to the example shown in Fig. 28. The "alarm type" is an item for selecting accuracy and response. As described above, the alarm type "full-auto" automatically selects one of the above alarm types. Therefore, three types can be selected for the alarm type: "full-auto", "accuracy", and "response" set by the user's manual selection.

[0315] As shown in FIGS. 29(A) and 30(A), the control unit 11 displays the currently selected mode and the like. In the illustrated example, the reception sensitivity is set to AAC / ASS in both cases. Also, for the alarm type, full auto is set in FIG. 29(A), and accuracy is set in the example shown in FIG. 30(A). By looking at this setting screen, the user can know the currently set mode and the like.

[0316] And each item is composed of soft buttons. Therefore, the user touches the item to be changed. The control unit 11 recognizes the touched item and displays the setting screen (FIGS. 29(B) and 30(B)) for the corresponding item. FIGS. 29(B) and 30(B) show the states after the alarm type is touched in FIGS. 29(A) and 30(A), respectively. When displaying this setting screen, the control unit 11 displays a line L under the currently selected item. It can be confirmed that full auto is set in FIG. 29(B) and accuracy is set in FIG. 30(B).

[0317] When the user changes the alarm type, the user touches a predetermined item on this setting screen. The control unit 11 recognizes the touched location, switches the setting of the alarm type (including full auto), and displays a line L under the touched item (not shown).

[0318] As described above, since the initial value has full auto turned on, the setting screen is as shown in FIG. 29. This full auto setting results in appropriate operation for many users. Also, users who want to avoid false alarms sounding may select the manual accuracy as shown in FIG. 30(B). On the other hand, for example, users who do not trust the full auto function or want to avoid a delay in detecting a portable orbis when the update of public enforcement information and deployment status is delayed and different from the actual situation should select reactivity. By selecting reactivity in this way, it operates with the highest level of excitement and the like. However, although the number of false alarms increases accordingly, it is acceptable because the user is aware of it. In this way, the electronic device 10 of the present embodiment can be set according to the user's preference.

[0319] The first method described the setting screen and setting method corresponding to the "6-3. Full Auto [MSSS] function", and the second method described the setting screen and setting method corresponding to the "6-5. Alarm Type 'Full Auto' function". This is the relationship of terms such as "false alarm reduction" and "accuracy and responsiveness", and by rewriting each of them, it can be used as the setting screen and setting method for another function.

[0320] [8.X·K Band Identification Alarm] When the control unit 11 performs a received alarm of a radar wave, it is preferable to identify the type of band and output different messages and alarm sounds for each band. By doing so, the user can understand which band of radar has been received without looking at the electronic device 10. In particular, when identifying MSSS, it is preferable to output a different alarm sound from others.

[0321] An example of the alarm sound may be as follows, for example. ·The alarm message for X-band reception may be "Radar (X-band)", "Radar X", "Radar X***", etc. The alarm message may be reproduced by voice or text-displayed at a predetermined position on the display unit 13. Also, the alarm sound may be, for example, 1 kHz. ·The alarm message for K-band (MSSS) reception may be "Portable Orbis MSSS", etc., and the alarm sound may be a characteristic sound such as "Piropiro, Queen Queen", for example. ·The alarm message for K-band (SSS) reception may be "Fixed Orbis SSS", etc., and the alarm sound may be a characteristic sound such as "Piropiro, Queen Queen", for example. It is more preferable to make it different from the case of "K-band (MSSS) reception". ·The alarm message for receiving K-band (not modulation-identified) may be "Radar (K-band)", "Radar K", "Radar K***", etc., and the alarm sound may be created with a different scale from the X-band, such as "Pee, Poo". Note that in the case of a K-band without modulation identification, there may be a reciprocal dialect, so a simple alarm sound may be used.

[0322] The recognition of radar waves from MSSS was described above as being based on the presence or absence of modulation, but additional conditions may be added. By adding conditions, MSSS can be detected with higher accuracy. The additional conditions may include, for example, looking at the frequency. Even for modulated K-band microwaves, if the frequency is outside the conditions, it should not be recognized as MSSS.

[0323] [9.Reception information collection and extraction function] The electronic device 10 has a function of storing and retaining the reception information when receiving radar waves. It is configured so that the stored reception information can be uploaded to an external database such as a server.

[0324] <9-1.Automatic memory function for reception frequency (VCO voltage), etc.> When receiving radio waves in the X-band or K-band, a superheterodyne reception circuit is used, the oscillation frequency of a local oscillator using a VCO (Voltage-controlled oscillator) is swept, and detection processing is performed. The oscillation frequency at which a predetermined radio wave is detected (received) can be specified by the VCO voltage.

[0325] The control unit 11 acquires the reception frequency (VCO voltage) as information when receiving a predetermined radio wave and stores it as one of the reception information. The reception information stored together with this VCO voltage may include, for example, position information for specifying the received position, frequency information, date and time information, reception level, type of band, presence or absence of modulation, etc. Also, the reception information may store information on the alarm sounded upon reception. The information on the alarm includes, for example, the loudness of the sound emitted, the volume level, etc. Also, when no alarm is sounded even though a reception occurs, information to that effect should be registered.

[0326] Also, the information to be stored may use, for example, the numerical values of each item, but it is better to take a snapshot of the entire setting screen at that time, such as the set volume level, and store it together as it is, and store it in a way that gives the impression that the settings during that drive were like this, and then upload it. Also, the setting screen should preferably contain information only about the settings that have been changed from the standard.

[0327] Also, for example, the electronic device 10 may cooperate with a drive recorder, and when receiving a radar or the like and when an alarm is notified accordingly, the electronic device 10 may acquire the image captured by the drive recorder and store it in association as received information. By doing so, for example, if a false alarm source such as a vending machine or an orbis appears in the captured image, it becomes easier to confirm the relationship with the received radio wave.

[0328] The radio waves to be stored may be, for example, K-band radio waves from a portable orbis such as MSSS, or X-band radio waves, and not limited to orbis, but may also be radio waves from false alarm sources. Also, whether it is a radio wave from a K-band orbis or a radio wave from a false alarm source may be determined by the presence or absence of modulation. The information to be stored may be, for example, the time of first reception, the time when modulation could be identified in the case of the K-band, the time when the reception level is maximum, etc. Also, it may be a history of a plurality of points taken periodically, such as every few msec or every second.

[0329] By doing so, for example, from the received information accompanying the reception of an orbis, it is possible to know the control area here, and in this city, for example, that enforcement was carried out using a radar wave with a VCO voltage in the vicinity of ○○ [V] in the K-band. When a predetermined modulation is confirmed with a K-band microwave, or when traveling the same place at the same time and receiving or not receiving, the possibility of an orbis is high. Also, if the same voltage radio wave is received at the same place every time, it can be said that the possibility of a false alarm is high.

[0330] And since the same type of orbis is often used in the same area, when driving in the same area after the next time, the control unit 11 may make a determination such as a high possibility of interference wave / high possibility of false alarm from the VCO voltage when receiving the radio wave, and perform a predetermined process.

[0331] The predetermined process may include, for example, notifying including the possibility of a radar reception alarm, notifying past information that has been stored (such as "receiving a radio wave with the same voltage as the radio wave received in the past"), or not notifying when the possibility of a false alarm is high. Also, for example, when the VCO voltage when receiving a radio wave from a false alarm source is different from the VCO when receiving an interference wave, it is advisable to discriminate between the two taking into account the VCO voltage. For example, store the VCO voltage when receiving the K-band radio wave emitted from the collision prevention system of a Mazda vehicle. And when the Mazda vehicle approaches again after leaving once and the alarm stops sounding, if it is the same VCO voltage, it is advisable not to notify it as a false alarm before confirming the modulation. By doing so, for example, even in a low state where the modulation / non-modulation cannot be discriminated such as when the reception level is level 1, it is possible to determine that there is a high possibility of a false alarm source or a portable orbis.

[0332] Also, for example, even if portable orbis, such as MSSS, etc. are mentioned together, various frequency bands are used within the K-band. For example, in a certain area A within Chiba Prefecture, an orbis with a lower frequency in the K-band is received, and in a different area B in the same Chiba Prefecture, an orbis may be received with a VCO voltage different from that in area A. Accumulate such information, create a list of the VCO voltages of the orbis detected in the same prefecture (Chiba Prefecture in this example), and when receiving a microwave of that voltage, it is advisable to notify an alarm to the effect that there is a high possibility of an orbis. Also, based on the information of different VCO voltages for each area, for example, when driving in area A and when driving in area B, it is advisable to change the alarm control.

[0333] Also, when the same specific radio wave is received during travel at a location where received information was previously stored, for example, when outputting an alarm notification, it may be appropriate to provide a notification indicating that a radio wave with the same characteristics as the previously received radio wave is being received.

[0334] <9-2. Questionnaire Function for Users> The control unit 11 of the electronic device 10 may be provided with a function of conducting a questionnaire on the received information stored together with the position information upon reception of a radio wave. For example, when the control unit 11 issues an alarm, when the electronic device 10 is next activated, it may conduct an inquiry (questionnaire) such as "Was the previous alarm too noisy?" and accept an answer of "Yes / No". The "Yes / No" information may also be stored in association with the information on the previously issued alarm and used for extraction.

[0335] When a modulated wave radio wave from a portable orbis is received in a prefecture where it is not equipped, or when an orbis radio wave is received in an area without orbis POI information regardless of whether it is equipped or not, the control unit 11 may conduct an inquiry such as "Was that the previous enforcement device?" and accept an answer of "Yes / No". When a "Yes" answer is received, when traveling in the same area next time, the control unit 11 may increase the sensitivity around that frequency band (VCO voltage) to make it easier to receive radar waves and identify modulated waves.

[0336] Also, the inquiry target is not limited to those exemplified above. For example, it may be assumed that there is a possibility of a new orbis. For example, if information on the radio wave attributes regarding regulators such as known orbis is held as a database and a radio wave with radio wave attributes not corresponding thereto is received, it is determined that there is a possibility of a new orbis. Then, the control unit 11 makes an inquiry such as "A radio wave not corresponding has been received. Was there something like a regulator?" or "……Was there a radar detector?" This inquiry may be made when the vehicle engine is started next after receiving the radio wave. Also, when the engine of the vehicle in the middle of driving this time is turned off and the electronic device 10 is operating with backup, it is best to make the inquiry at that time. The inquiry made when the engine of the next vehicle is started may be, for example, "Did you know that the radio wave was received when you drove last time?" or "Did you know that the radio wave was received when you drove on [date]?" or "Was there a radar detector at that time?"

[0337] In response to these inquiries, when the control unit 11 of the electronic device 10 receives an answer of "Yes", it makes a reconfirmation inquiry such as "Do you register it as a new detector?" If the answer is "Yes", when a radio wave with the same attribute is received next, control is performed to issue an alarm as a new orbis or a regulator found by the user, a new regulator.

[0338] Also, when the radio wave attribute database regarding the orbis operating in the region is stored for each prefecture, data on the radio wave attributes corresponding to the currently existing prefectures is retrieved. Then, the control unit 11 may separate the processing according to the data retrieved from the database. It is good to have such a characteristic as a database and intensively sweep the range regarding the registered radio wave attributes.

[0339] Also, in response to an inquiry such as "Was there a radar detector?" above, if an answer of "Not seen" is received, it is regarded as a false alarm candidate, and if the same result occurs a predetermined number of times or more (for example, 3 times), it is registered as a false alarm.

[0340] In addition, inquiries regarding the reception of radio waves from the collision prevention system of Mazda vehicles may be, for example, "Around what time did you have a vehicle driving alongside?" However, since users often do not remember such questions, it is advisable to make a judgment based on the information obtained by photographing the vehicle driving alongside. The information obtained by photographing the vehicle driving alongside may, for example, use the images captured by a drive recorder, and it is advisable to identify it from the correspondence between the reception date and time of the radio wave and the shooting date and time of the corresponding image in the drive recorder. Then, for example, the identified image may be given to an AI and configured to identify the vehicle type.

[0341] <9-3. Information uploading (upload function)> The electronic device 10 performs various processes in association with the reception of radio waves and stores and accumulates the received information. It is advisable for a large number of users to upload the stored and accumulated information to a server, and for the server to aggregate the received information. As a result, by using and analyzing bigger data, it is possible to accurately and widely determine the usage locations of Orbis, the positions of false alarm sources, and the VCO voltages at the time of radio wave reception used in those cases. For example, for the same person, the frequency of driving in the same location is limited, but by aggregating the received information collected by a large number of people, it is possible to collect a large amount of received information when driving in the same location, for example. As a result, for example, when receiving radio waves at the same VCO voltage at the same location regardless of day or night, it can be said that the possibility of a false alarm source is high. For example, if everyone (for example, about 5 people) receives radio waves of the same received information at the same place, it can be said that it is suspicious (a false alarm source). Also, when receiving radio waves at the same VCO voltage during a certain time period on the same day and not receiving radio waves on different days or at different time periods on the same day, it can be said that the possibility of radio waves from a portable Orbis is high. And by paying attention to the VCO voltage, the control can be appropriately changed based on the VCO voltage.

[0342] (9-3-1. Upload function using a storage medium 50 such as an SD card) When the control unit 11 receives orbits or lasers, it records and stores the received information such as position information, frequency information, band, date and time, VCO voltage, and presence or absence of modulation in the storage medium 50. When downloading and updating public regulation information, POI information, etc., a storage medium such as an SD card is set in a personal computer, and a tool installed in the personal computer accesses a predetermined server, and the necessary information is downloaded to the set storage medium. In such a case, it is preferable to use the storage medium 50 that records and stores the above received information as the storage medium.

[0343] Then, at a predetermined timing such as when downloading public regulation information or after downloading, the tool displays a message asking for permission to upload (upload) to the user on the display unit of the personal computer, such as "May I pick up the received information recorded in the storage medium?" or "There is a history of that warning during driving so far in the SD card. May I provide that information?" When the tool receives a permission instruction input via a predetermined input device, it reads out the received information stored in the storage medium 50 and uploads it to a predetermined server. In this way, it is preferable to perform the upload process at the timing of downloading. It is troublesome for the user to take out the storage medium 50 from the electronic device 10 and set it in the personal computer for uploading, and there is a high possibility that it will not be executed easily. On the other hand, by performing the upload of the received information at the timing of downloading for updating, it is possible to reduce the resistance to uploading and make it easier to upload useful received information without giving the user special work or burden.

[0344] The suction timing may be the timing when the above tools or an app for downloading public regulatory information, POI, etc. is launched. Also, it is not limited to the download timing, and it may be the timing when an app or the like is launched without downloading. For example, when the app is launched, a message such as "Please insert the SD card (storage medium 50)" is output in a pop-up or the like. Then, when the SD card is set, the app accesses the SD card and checks whether the data of the received information is stored. If there is received information, the app displays a permission request message such as "May I suck up the stored received information?" Then, when the app or the like receives a permission instruction input via a predetermined input device, it reads out the received information stored in the storage medium 50 and uploads it to a predetermined server.

[0345] For example, install an app that executes the above suction process on the SD card. And when the app on the SD card is launched, it may be configured to execute the above suction process. It is preferable to use an SD card on which public regulatory information, POI information, etc. are written. The electronic device 10, which is a radar detector, may be equipped with a function to execute the process of the above app. And that function outputs a permission request message, for example, at the timing of downloading public regulatory information, etc., and uploads predetermined received information when permission is received. This upload may be performed using a predetermined communication function, for example.

[0346] When suction is performed at the time of downloading update information as described above, as an incentive for the user, the process of inserting the SD card is not for uploading received information, but for the user to obtain the latest information. Therefore, it is preferable to perform suction in accordance with the download rather than prompting suction at the time of launching an app or the like regardless of the download.

[0347] In addition, users who provide information when the upload is executed may be given a predetermined number of points, for example, 100 points, or reflected in the ranking of information providers. Reflection in the ranking, that is, the ranking may be improved according to the information provided, and competition may be held in the ranking to satisfy the desire for approval.

[0348] Also, similar to a splash window, when the electronic device 10 is started up, a message prompting the upload of received information and information provision, such as "You can get points if you provide the received information", may be displayed on the startup screen. In addition, the electronic device 10 may display a message such as "The usage method of the SD card is here, this QR code (registered trademark)". The QR code (registered trademark) may indicate information for accessing a site that guides the usage method.

[0349] In addition, when an image taken of the surroundings is stored as received information, the upload may be performed on the condition of special permission. The special permission requests an upload permission separately from the permission when uploading other normal received information. For the permission to upload a photo, for example, the photo may be displayed as a thumbnail and the user may be asked to confirm the content of the photo and give permission.

[0350] (9-3-2. Upload function when a portable orbis is detected in a prefecture without deployment) If a predetermined modulated wave in the K band is received even though the bit of a portable orbis such as MSSS in the header part of the public censorship information is not set, it is registered once in the my area based on the current position. As a result, each time the control unit 11 passes through the my area hereafter, an alarm based on the position information is issued. By registering in the my area, an alarm is notified when passing through that place hereafter.

[0351] When receiving a modulated wave in the K band, it is dangerous to register it as a false alarm source. That is, even if the deployment status is an undeployed prefecture, there may be a time lag between actual deployment and public release, it may not be publicly released intentionally, or the data may not be updated at all and the header part may remain undeployed. Therefore, it is registered in the my area as described above, and an alarm is issued thereafter. Also, the control unit 11 may store the location where the above-mentioned portable orbis-like radio wave is received, and increase the sensitivity only in the vicinity when passing through the vicinity next time.

[0352] Furthermore, when the control unit 11 receives a radar wave from a portable orbis in an undeployed prefecture as described above, for example, it displays a permission request message such as "Do you want to provide information?" in a pop-up. And when receiving a permission notification from the user, it uploads the received information including the location information and the portable orbis (and the name if the type is specified). This upload may be performed using communication, for example.

[0353] Also, the permission request message may be issued when modulation is recognized, or may be issued when the engine is started next. Also, when map data is provided, it specifies the detection location on the map based on the location information, and displays a message "Received here" together with an icon mark indicating the detection location on the map. And when the control unit 11 receives a permission notification, it may post it to a predetermined site so that the user can obtain points.

[0354] <9-4. Method for collecting a lot of information> A big data accumulation method may be configured to collect as much information as possible from an edge (for example, an electronic device that moves with a vehicle (such as a radar detector, etc.)) at a frequency as high as possible and analyze it on the server side.

[0355] By doing so, it becomes possible to handle various purposes, even if the purpose changes later (such as grasping signs for autonomous driving and the current status of road lanes), or even if the purpose is determined, for example, for specifying the installation position of a portable orbis (sometimes referred to as a "mobile orbis"), and an unexpected relationship between the explanatory variable (sensor information, etc.) and the objective variable (mobile orbis installation position) is discovered through multiple regression analysis or the like.

[0356] The electronic device 10 preferably has a function of acquiring a large amount of information at high frequency (for example, 10 times per second) and transmitting to the server as close as possible to the raw data. The information to be acquired includes, for example, received radio wave intensity, received frequency, presence or absence of modulation, type of polarization, etc. when receiving a predetermined radio wave, and it is preferably stored in association with the time information and position information when these information are acquired. In addition, the information to be collected exemplified above relates to radio waves associated with the reception of radio waves such as microwaves, but is not limited thereto, and includes, for example, information acquired from other in-vehicle devices such as a drive recorder (such as captured images) and various vehicle information acquired from an OBDII adapter (such as vehicle speed and acceleration).

[0357] When the server receives a large number of data collected in time series from the electronic device 10, it stores them in association with information for identifying the electronic device (such as device ID). As a result, the server stores data associated with a time series as shown in, for example, FIG. 32.

[0358] Then, based on the data collected in this way, the server, for example, obtains the traveling direction from positions 1, 2,... clusters the data of different device IDs having the same traveling direction with approximate positions to separate the traveling directions, and has a function of specifying the orbis position from an analysis similar to the intensity history described later in the following "9-5. Processing method of strictly selecting the data collection amount for the purpose of specifying the installation location of the mobile orbis".

[0359] Also, the program on the electronic device side is preferably configured to be rewritten from the server side. This also applies to "9-5" and "9-6" described below.

[0360] <9-5. Method of strictly selecting data collection amount, focusing on the purpose of specifying the installation location of the mobile orbis> It is advisable to adopt a method for determining the installation position of the mobile orbis at the edge (for example, an electronic device that moves with a vehicle (such as a radar detector, etc.)) to specify that the installation position of the mobile orbis is here! and only send the information of that position to the server.

[0361] For example, receive radar waves (RD waves) with a strong intensity over a predetermined distance rather than a short distance such as a vending machine or an automatic door (however, exclude when the distance is extremely long because it is a Mazda car), and send the position information + time of the point where the intensity rapidly decays to the server.

[0362] In FIG. 33, assuming that "●" represents the orbis position, it is estimated that the received level changes as shown when traveling in the measurement lane and the oncoming lane. And it can be inferred that the position where the level drops rapidly from a strong level to a high level is the orbis position. Also, the level in the oncoming lane is weak, so it is not sent to the server. Since the data to be sent is only point and time data, the data volume becomes very small.

[0363] <9-6. Various methods intermediate between 9-4 and 9-5> For example, it is advisable to increase the types of information to be added, such as adding the traveling direction in 8 directions, etc., adding the received level, adding the reception start position, etc. to the information of the above "9-5.". Or, for example, use methods such as reducing information from the above "9-4.", such as changing the frequency to 5 times per second, or making it the degree of the history of the position where the received level for RD determination changes.

[0364] Also, for example, regarding one way of assigning an individual ID to an electronic device, if the purpose is simply to determine "from which individual electronic device (RD) the data was sent", for example, the server can send the individual ID to the electronic device (RD), store the ID in a non-volatile memory or the like, and then the electronic device (RD) can send it to the server. However, if the purpose includes "quality verification (variation measurement) of the radar module of the electronic device (RD) individual", the individual ID should be the model ID and the manufacturing number.

[0365] [10. IR module (rear laser) connection function] <10-1. Basic system configuration> As shown in FIG. 31, the system includes an electronic device 10 disposed at a predetermined position in front of the vehicle 40 and a laser receiving unit 80 that operates as a rear unit and is disposed at a predetermined position behind the vehicle 40. The electronic device 10 and the laser receiving unit 80 are communicably connected.

[0366] The system of this embodiment includes, for example, a rear receiving function corresponding to the laser light emitted from a laser patrol car. The laser patrol car is equipped with a laser-type vehicle speed measuring device. Then, the laser patrol car parks and waits, for example, on the road shoulder, emits laser light to the vehicle passing in front of the patrol car, and measures the traveling speed of the passing vehicle. Therefore, the laser light emitted by the laser patrol car comes from the rear of the vehicle. The laser receiving unit 80 preferably has a function of detecting this laser light from the laser patrol car.

[0367] As described above, the electronic device 10 receives a predetermined microwave and laser light from the front. Also, the laser receiving unit 80 that operates as a rear unit receives a predetermined laser light from the rear. Then, the control unit 11 mounted on the electronic device 10 that constitutes this system preferably performs control to give a predetermined notification based on the reception information of the electronic device 10 and the reception information of the rear receiving unit.

[0368] The antennas of each receiver are installed such that the front-facing electronic device 10 has directivity forward, and the laser receiver unit 80 has strong directivity backward. Also, the laser receiver unit 80 is installed at a position where it can receive laser light coming into the vehicle interior, for example, through the rear glass. Further, the electronic device 10 includes an integrated or separate display unit 13, but it is preferable that the laser receiver unit 80 does not include a display unit. Since it does not have a display unit, it becomes small and compact, does not obstruct the driver's rear view seen through the rearview mirror, and increases the degree of freedom in the installation position.

[0369] The communication performed between the electronic device 10 and the laser receiver unit 80 may be configured to transmit and receive data by, for example, IR communication (infrared communication) using a remote control signal using infrared rays. By doing so, it becomes unnecessary to physically connect the electronic device 10 arranged in the front of the vehicle and the laser receiver unit 80 installed in the rear of the vehicle with a connection cable or the like. Therefore, the wiring work of laying a wiring cable inside the vehicle becomes unnecessary, and the work of installing the system in the vehicle can be easily performed. Also, the degree of freedom in the installation positions of the electronic device 10 and the laser receiver unit 80 increases.

[0370] As the electronic device 10, those shown in the above-described embodiments may be used. Although a part of the configuration is illustrated in FIG. 31(B), the electronic device 10 includes a radar receiver unit 15 that receives a predetermined microwave, a light receiving unit 12 that receives laser light, and the like. Also, the control unit 11 notifies a predetermined warning from the display unit 13 and the voice output unit 14 based on the received information. Further, the electronic device 10 includes a remote control receiver 26 for performing IR communication. This remote control receiver 26 has a PD (photodiode) for an infrared remote control. Also, the control unit 11 performs predetermined control based on the remote control signal received by the remote control receiver 26.

[0371] The laser receiving unit 80 includes a light receiving unit 82 that receives laser light, a control unit 81 that performs predetermined processing based on the received information and communicates with the electronic device 10, and a remote controller transmitter 83 and the like. The light receiving unit 82 may use the same one as the light receiving unit 12 mounted on the electronic device 10. Alternatively, a different one may be used.

[0372] The remote controller transmitter 83 includes an infrared LED. The infrared LED is preferably configured to emit light in a direction different from the light receiving surface of the light receiving unit 82 of the laser receiving unit 80, and may be configured to emit light toward the opposite side. When emitting light toward the opposite side, the light receiving unit 82 and the remote controller transmitter 83 are preferably provided on the opposite side surface of the case of the laser receiving unit 80, respectively. In this way, when the laser receiving unit 80 is installed at the rear of the vehicle, the light receiving unit 82 can efficiently receive the laser from the rear. In addition, the remote controller transmitter 83 can emit a predetermined code toward the front of the vehicle 40 and can be surely received by the remote controller receiver 26 of the electronic device 10 installed in the front.

[0373] When attaching this laser receiving unit 80 to a predetermined position on the rear side of the vehicle 40, for example, it may be attached to the rear glass of the vehicle 40 using a predetermined mounting bracket.

[0374] Also, the power supply of this laser receiving unit 80 may obtain power from, for example, the cigarette socket near the front seat of the vehicle 40 or the cigarette socket in the rear seat and luggage space. In particular, when using the cigarette socket in the rear seat and luggage space, the length of the power cable is short and the wiring is less likely to be in the way.

[0375] The control unit 81 controls the emission of the infrared LED and transmits a predetermined code. The predetermined code includes a test code for connection confirmation and a reception code for notifying the reception of a predetermined laser beam. Further, as described above, the laser reception unit 80 of the present embodiment has a dual function of detecting a laser beam from the rear when installed at the rear of the vehicle 40 and transmitting the detected beam to the electronic device 10, and detecting a laser beam from the front when installed in front of the vehicle 40 and transmitting the detected beam to the electronic device 10. The code for notifying reception includes a code for notifying front reception and a code for notifying rear reception.

[0376] The control unit 81 of the laser reception unit 80 generates a test code and a code indicating front / rear reception at a predetermined timing, and transmits a predetermined transmission pulse. In the present embodiment, the laser reception unit 80 stores and holds the front / rear installation information indicating whether it is operating in the front or the rear. When the control unit 81 receives a laser beam, it generates and transmits a code indicating "front reception" or "rear reception" based on the front / rear installation information. The front / rear installation information for distinguishing between the front and the rear is set when the laser reception unit 80 is installed. Note that the front / rear setting function will be described later.

[0377] Furthermore, since the remote control receiver 26 also receives, for example, a remote control signal for setting, it is advisable to prepare a dedicated code different from the remote control signal for setting. This prevents the electronic device 10 from malfunctioning.

[0378] The dedicated code may be, for example, Test (connection confirmation): 60h Reception (front): 61h Reception (rear): 62h It is advisable to set them like this.

[0379] Conventionally, the content of the remote control key was set to transition to the setting mode. However, since the hierarchy becomes complex, it is advisable to use a dedicated code as described above. Also, the remote control signal for the setting code is, for example, Volume up: 14 Volume down: 13 Test & mute: 11h My Cancellation: 22h Standby Switching: 12h It is advisable to do so.

[0380] Accordingly, a separately prepared remote control device is configured to transmit the above-described setting code. Then, the electronic device 10 receives the setting code with the remote control receiver 26. And the control unit 11 may have a function of setting the operation content of the electronic device 10 based on the received dedicated code. Accordingly, the electronic device 10 has a function of performing a predetermined notification based on the reception of a dedicated code using IR communication from the laser reception unit 80, and a function of performing various corresponding settings based on the reception of a setting code from the remote control device. Since settings can be made by remote control operation, the user's setting operation becomes easy.

[0381] As described above, the system of the present embodiment is characterized in that when a signal suitable for an alarm such as a laser arrives, it is sent as an infrared remote control code instead of an alarm or a communication signal. Also, as described above, the infrared remote control may be received by a PD (photodiode) for the infrared remote control.

[0382] Further, when transmitting this dedicated code, the remote control transmitter 83 periodically transmits the same signal during a period satisfying transmission conditions such as during reception of a laser wave or at startup. That is, an ordinary remote control sends a predetermined signal once and then transmits a fixed repeat code, but the dedicated code of the present embodiment is different in that it does not send a repeat code and periodically transmits the corresponding code described above. The interval for periodically transmitting the dedicated code of the present embodiment may be, for example, 100 msec.

[0383] Between the laser receiving unit 80 installed at the rear and the electronic device 10 as in this embodiment, there is, for example, a rear seat, and in some cases, such as when a child is running wild in the rear seat, a shadow is formed, and the code initially transmitted by the remote control transmitter 83 may not be received by the remote control receiver 26 of the electronic device 10. In such a case, if it is a repeat code, the control unit 11 of the electronic device 10 cannot understand the meaning of the signal, and there is a risk that, for example, a reception warning for the rear laser cannot be issued. In this embodiment, even if the electronic device 10 fails to receive the dedicated code from the laser receiving unit 80 once, the control unit 11 can understand the meaning of the remote control signal and issue a reception warning for the rear laser, for example, by receiving the dedicated code sent later.

[0384] <10-2. Front / Back Setting Function When Laser Receiving Unit 80 is Installed> As described above, when the control unit 81 of the laser receiving unit 80 receives a predetermined laser beam, it transmits a dedicated code indicating reception based on the front / back installation information stored and held in the storage unit. In this embodiment, for rear installation, the control unit 81 transmits the dedicated code 62H indicating reception (rear) from the remote control transmitter 83.

[0385] Also, although not shown in the drawings, the laser receiving unit 80 of this embodiment has one push-button type operation button. It is preferable to be able to set whether it is installed in the front or, as in this embodiment, in the rear by operating the operation button.

[0386] For example, based on the operation on the operation button when the laser receiving unit 80 is powered on, the control unit 81 may determine and set it in the storage unit. For example, when the power is turned on while pressing the operation button, it may be set for the rear, and when the power is turned on without pressing the operation button, it may be set for the front.

[0387] Also, it may be configured to set the front / back by the number of presses or the pressing time (short press or long press). As described above, setting it to pressed / not pressed is good because the user can easily understand it and the operation errors are reduced.

[0388] For example, on the side of the electronic device 10, it is set whether the laser receiving unit 80 is for the front or the rear. Then, the control unit 11 of the electronic device 10 may transmit setting information to the laser receiving unit 80, and the laser receiving unit 80 may store the received setting information. However, in order to implement such a setting method, since it is necessary to communicate from the side of the electronic device 10 to the laser receiving unit 80, it is better to set on the side of the laser receiving unit 80 as described above.

[0389] Also, when connecting one laser receiving unit 80 to the electronic device 10 as in this embodiment, the front / rear installation information is set on the side of the electronic device 10 as described above, and the laser receiving unit 80 may transmit a dedicated code indicating reception (without distinction between front and rear) when receiving the laser light. In this way, when the control unit 11 of the electronic device 10 receives the dedicated code indicating reception, it may recognize from which direction, front or rear, the laser is received based on the front / rear installation information stored and held by itself, and perform a desired notification.

[0390] However, in the case where the laser receiving units 80 are installed in the front and the rear, the installation information may be stored on the side of the laser receiving unit 80, and in the case of multiple installations, it may be configured to transmit either "Reception (front): 61h" or "Reception (rear): 62h" as in this embodiment.

[0391] As the operation switch, it is preferable to use one that can specify a plurality of states such as a DIP switch or a slide switch. In this way, the control unit 81 may transmit either reception (front) or reception (rear) based on the position of the switch when a predetermined laser light is received.

[0392] Further, the laser receiving unit may be provided with a sensor for recognizing its installation orientation, and may have a function of determining and registering the front / rear based on the output of the sensor. For example, the laser receiving unit 80 is provided with a G sensor. The vibration is overwhelmingly larger in the front. It may have a function of automatically discriminating and registering the front / rear based on the magnitude of the vibration, the direction of the acceleration, etc.

[0393] <10-3. Receivable Range of Infrared LED of Remote Control Transmitter 83> As described above, when the laser receiving unit 80 of the present embodiment functions as a rear receiving unit, for example, "Install an infrared LED with the front facing the rear receiving unit, Provide a light receiving unit for receiving the light of the infrared LED in the front installed RD (electronic device 10), Configure to transmit a signal notifying reception when receiving radio waves or light in the rear receiving unit to the light receiving unit by the emission of the infrared LED, A system that sets the receivable range of the infrared LED to a range where it cannot be received by a vehicle parked adjacent (for example, directivity, intensity). " It may be set like this.

[0394] If the receivable range of the infrared LED of the remote control transmitter 83 equipped with the infrared LED is configured to be within the vehicle of the vehicle 40 where the electronic device 10 and the laser receiving unit 80 are installed, when parked in a parking lot where multiple vehicles are parked side by side, it is possible to suppress the reaction of an electronic device equipped with a remote control receiving function parked next to it.

[0395] Conversely, it is preferable that the receivable range of the infrared LED of the remote control transmitter 83 includes outside the own vehicle. The outside of the own vehicle may be, for example, a range including one adjacent vehicle, and it is preferable to be such that an electronic device equipped with a remote control receiving function parked next to it can receive. By doing so, the signal of the dedicated code emitted from the remote control transmitter 83 has a strong output intensity and is emitted over a wide range, so the remote control receiver 26 of the electronic device 10 can surely receive it.

[0396] In addition, when set to such a reception range, in an actual parking lot, the electronic devices mounted on adjacent vehicles are often powered off and there is no problem. Also, when the host vehicle and other vehicles are traveling on the road in parallel, even if an electronic device equipped with a remote control reception function mounted on another vehicle receives the dedicated code transmitted from the remote control transmitter 83, there is almost no influence that it will malfunction based on the reception, so there is no problem. Further, if the same type of electronic device is mounted on another vehicle, based on the dedicated code from the remote control transmitter 83 of the laser reception unit 80 mounted on the vehicle 40, an alarm for laser reception from the rear can be notified. Conversely, based on the signal from the laser reception unit 80 mounted on another vehicle, the control unit 11 can notify an alarm for rear laser reception. Thereby, the presence of the laser patrol car can be more reliably notified and the user can recognize it.

[0397] The remote control transmitter 83 that implements such an operational effect may be set to be stronger than the power of a general remote control device and wider than the directivity of the infrared signal emitted from the remote control device.

[0398] <10-4. Connection Test Signal Transmission Function> When the control unit 81 of the laser reception unit 80, which is an example of the rear reception unit, receives a predetermined operation on the operation button, even if it is not receiving laser light, it causes the infrared LED of the remote control transmitter 83 to emit light and transmits a predetermined dedicated code. The electronic device 10 receives the sent dedicated code and performs predetermined processing. The predetermined operation may be, for example, a long press or two consecutive short presses. Also, the predetermined dedicated code may be, for example, "Test (Connection Confirmation): 60h".

[0399] The control unit 11 of the electronic device 10 may, as a predetermined process, notify, for example, the completion of connection confirmation. This notification may be, for example, to display a predetermined message, such as "Test successful", "Rear check completed", etc. on the display unit 13, or to notify by voice or the like. Further, as a dedicated code, for example, "Reception (rear): 62h" may be transmitted. In this way, the control unit 11 of the electronic device 10 that has received the dedicated code indicating reception performs a process of notifying a reception warning for the rear laser. Thereby, it can be confirmed that the laser reception unit 80 installed at the rear is connected to the electronic device 10 and the reception of the rear laser can be performed. In addition, the user can know in advance the warning when actually receiving the laser light from the rear, and can perform a safe driving operation without panicking when actually in such a situation.

[0400] <10-5. Function for adjusting the emission level based on the operation on the operation button> When the control unit 81 receives a predetermined operation on the operation button, it may have a function of changing the emission level of the infrared LED to a level corresponding to the operation. For example, the emission level may be gradually increased in the order of pressing twice continuously, three times continuously, four times continuously, and so on.

[0401] Further, each time the control unit 81 changes the emission level, it outputs a predetermined dedicated code. And when the user performs an operation such as stopping the short-pressing operation of the button when the electronic device 10 shows a reaction indicating reception of the dedicated code. In this way, it is possible to prevent the emission level from becoming excessive and being received by the electronic devices 10 of other vehicles, and it is possible to surely confirm that the light has been received in the front.

[0402] Note that in order to increase the emission level and surely transmit the dedicated code to the electronic device 10 side by the electronic device 10, after the electronic device 10 shows a reaction indicating reception as described above, the operation may be repeated a predetermined number of times to increase the emission level.

[0403] In addition, in the present embodiment, since the operation button is a push-button type, the above specifications are adopted. However, for example, a volume, a slide switch, etc. may be used.

[0404] <Connection Confirmation Function of Laser Receiver Unit 80> The laser receiver unit 80, which is an example of the rear receiver unit, performs a process of emitting an infrared LED even when it does not receive a laser for a certain period of time (e.g., 30 seconds) when the power is turned on. When the electronic device 10 installed in the front can receive this infrared light, the control unit 11 performs a process of writing a rear receiver unit installed flag to the non-volatile memory in the electronic device 10. Note that at the time of manufacturing or factory shipment, the rear receiver unit installed flag is reset after testing.

[0405] When the installed flag is set at the time of power-on, that is, when it is stored in the non-volatile memory but not received, the control unit 11 performs a process of notifying an abnormality. The notification of the abnormality may be, for example, a notification that there may be an obstacle between the laser receiver unit 80 and the electronic device 10, or that the power of the rear laser receiver unit 80 may not be connected. By doing so, the user can know that although the laser receiver unit 80 is installed at the rear, it is in a state where it cannot detect laser reception from the rear while not being connected to the electronic device 10. Also, accordingly, the user can correct the laser receiver unit 80 so that it operates normally and the electronic device 10 can receive a signal.

[0406] Also, when the control unit 11 of the electronic device 10 receives light in a state where the installed flag is set at the time of power-on, it may start up as it is without particularly notifying and perform normal control. Therefore, it is advisable to notify only when the light is not received. By doing so, although some users may find it troublesome or annoying to receive notifications such as "Rear laser is valid" every time they start up, appropriate startup operations can be performed for such users.

[0407] Also, since the initial value of this installed flag is reset, in the case of a system where the laser receiver unit 80 is not installed, no notification is made even if no light is received. Therefore, frequent notification of abnormalities at startup is eliminated.

[0408] Further, for example, it is preferable to provide a function for resetting this installed flag from a setting screen or the like of the electronic device 10. Thereby, for example, once the laser receiving unit 80 is installed and then removed, it is possible to eliminate the occurrence of an abnormality notification every time the power is turned on.

[0409] <10-7. Cable connection and use type> In the above-described embodiment, the laser receiving unit 80 installed at the rear communicates with the electronic device 10 using IR communication and transmits and receives data. However, it is preferable to additionally provide a function of connecting by wire using a communication cable. In this way, among IR communication and the cable, a system can be constructed by selecting the more convenient one.

[0410] For example, when the vehicle is a minivan or the like and there are many luggage piled up indoors and IR communication cannot transmit information, it is preferable to communicate using a cable. Further, for example, when the laser receiving unit 80 is of a type that can be installed either in the front or the rear, when installed at the rear, IR communication may be used, and when installed in the front, communication may be performed using a cable.

[0411] In these cases, the control unit 81 of the laser receiving unit 80 preferably has a function of not emitting light from the infrared LED when the laser receiving unit 80 and the electronic device 10 are connected by cable connection. Whether the cable is connected or not may be provided with a function of arranging a switch or a sensor near the connection port of the cable to detect whether the cable is connected or not.

[0412] <10-8. Receiving a remote control signal by the light receiving unit 12 for the laser of the electronic device 10> The wavelength of the transmission pulse of the IR communication is made the same as the wavelength of the laser, and the electronic device 10 may be made capable of receiving the dedicated code from the remote control transmitter 83 by the light receiving unit 12 that receives the laser light of the cancellation wave from the front. In this way, the remote control receiver 26 for receiving the infrared remote control signal becomes unnecessary.

[0413] In addition, the light-receiving surface of the light-receiving unit 12 of the electronic device 10 faces the front of the vehicle and does not face the remote control transmitter 83 of the laser receiving unit 80 installed at the rear. Even in such a case, the infrared signal emitted from the remote control transmitter 83 travels forward toward the vehicle 40, and for example, is reflected by the windshield and changes its travel path. Since the windshield is inclined obliquely downward toward the front lower side, the reflected light travels obliquely downward toward the rear. Due to this reflected light, diffused light, etc., the remote control signal emitted from the remote control transmitter 83 can be received by the light-receiving unit 12. Also, when installing the laser receiving unit 80 and the electronic device 10, it is advisable to adjust their respective installation positions, directions, and postures so that the reflected light on the windshield is received by the light-receiving unit 12.

[0414] Also, since the pattern of the laser light from the orbis received by the light-receiving unit 12 and the signal of the dedicated code of the remote control for notifying rear reception are different, the control unit 11 can discriminate between the two.

[0415] <10-9. Control Based on Deployment Status> The laser patrol car, which is the detection target of the laser receiving unit 80 installed at the rear, is deployed in specific prefectures such as Hokkaido. Therefore, similar to the deployment status of the portable orbis, it is advisable to register the deployment status of the laser patrol car for each predetermined area such as by prefecture and control the detection function of the laser patrol car based on the current position.

[0416] The control unit 11 of the electronic device 10 checks the deployment status of the currently existing prefecture, and in the case of the prefecture where the laser patrol car is deployed, it is advisable to display "Laser Patrol" as the orbis name icon 53. When a plurality of portable orbises are deployed in the same prefecture, all the orbis name icons 53 should be displayed, and "Laser Patrol" indicating the prefecture where this laser patrol car is deployed should also be displayed on the same screen.

[0417] Also, in the case of a prefecture where the laser patrol car is not deployed, it may be configured to turn off the remote control receiver 26, or operate the remote control receiver 26 but only enable the operation of a general remote control.

[0418] To perform such control, for example, a bit for this laser patrol car may be prepared in a part that registers the deployment status of the header part of the public regulation information, and the operation may be controlled based on it.

[0419] <10-10. Function to notify reception of rear laser> In each of the above-described embodiments, when the laser reception unit 80 installed at the rear receives a laser, it notifies the electronic device 10 using IR communication so that the electronic device 10 performs an alarm notification. In addition to or instead of this function, the laser reception unit 80 may be provided with a function to notify.

[0420] For example, an alarm LED that emits visible light is arranged at a predetermined position on the surface opposite to the light receiving part 82 of the laser reception unit 80, that is, the surface facing the inside of the vehicle cabin. When the control unit 81 detects the reception of a predetermined laser, it controls to turn on the alarm LED.

[0421] In this embodiment, since the laser reception unit 80 is installed at the rear, it is difficult for a user such as a driver to directly view the alarm LED during driving, but it can be visually recognized through the rearview mirror. In particular, by using an alarm LED with a large size and shape, it becomes possible to recognize that something is glowing through the rearview mirror. The large size and shape may be such that when the driver is looking ahead while driving, the alarm LED lights up at the edge of the field of view through the rearview mirror and can be recognized.

[0422] Also, an alarm LED may be provided and caused to emit light at an appropriate timing separately from the alarm. By this light emission, the user can confirm that the laser reception unit 80 is operating and at least the power is ON.

[0423] <10-11. System with Rear Radar Receiver Function> In this embodiment, the laser receiving unit 80 is configured to have a laser receiving function but not a radar receiving function. However, it may be configured to have a radar receiving function. In this case, it is preferable to use IR communication for the notification to the electronic device 10 when a radar from the rear is received.

[0424] Furthermore, the reception notification using this IR communication is not limited to those having a function of receiving a laser like the laser receiving unit 80, and is preferably applied to a radar receiving unit that receives only a predetermined radar.

[0425] [11. Alarm Sound of Character Radar] An electronic device in which a character issues an alarm, where there are a plurality of characters, and each character has its own song. The electronic device 10 stores in the storage unit 25 or the storage medium 50 the audio files of the predetermined songs of each character in association with the characters. The audio files of the predetermined songs are preferably karaoke versions without the recorded song (vocal). When the alarm is notified with the character function turned on, the control unit 11 reads out the audio file associated with the currently set character from the storage unit 25 or the storage medium 50 and sounds the karaoke version without the song as the alarm sound.

[0426] When sounding the song with the lyrics, the user is likely to pay attention to the content of the song (lyrics), and the content of the alarm notification may be difficult to understand. Therefore, especially when the electronic device 10 is operating in the character mode, the control unit 11 is preferably configured to notify the karaoke version without sound.

[0427] Furthermore, general karaoke sound sources without lyrics (vocals) may only have rhythm and can be difficult to understand. Therefore, a vocal file of the main melody karaoke version with a melody line added is stored and held in the storage unit 25 or the storage medium 50. When the control unit 11 receives a signal of an interference wave, it reads out and notifies the karaoke version with the above-mentioned melody line from the storage unit 25 or the like, and stops the output of the karaoke when the signal of the interference wave disappears.

[0428] In addition, as a single setting screen for performing various settings, the electronic device 10 has, for example, a menu screen for selecting which character to enable. When the control unit 11 detects that an item has been touched when operating the menu screen to select a character or the like, it has a function of playing the holding song associated with the touched character. At this time, the control unit 11 plays with singing. In this way, the music with singing can only be played during the selection process of the menu screen, and is notified without singing during normal alarms. Also, on the menu screen, there is a button for selecting whether to play with singing (vocal version) or without singing (karaoke version), and it is preferable to be able to play the selected music. By doing so, the user can check including what the song is like. To realize such a function, an audio file of the music with singing (vocal version) and an audio file of the music without singing (karaoke version) are respectively stored in the storage unit 25 or the storage medium 50, and the control unit 11 may execute a process of reading out and playing one of the audio files based on an operation on the menu screen.

[0429] As described above, it is preferable to be an electronic device or system in which the music sounded for warning is a version without vocals and includes a melody line. By doing so, at the time of warning, the user can understand the melody and, since there is no singing, will not be drawn in more than necessary, and can suppress as much as possible the situation of missing or overlooking the content of the warning such as the type of warning.

[0430] [12. Discrimination Function of Radar Waves] <12-1. Discrimination of Modulated Waves of Radar for Portable Orbiter and Collision Prevention System> The modulation method of MSSS adopted in the portable orbiter seems to be binary FSK. The modulation method of JMA is also said to be the same. Although both are microwaves in the K band, the frequencies are different. In addition, the radar adopted in the collision prevention system of Mazda cars seems to be pulse modulation (using one frequency, not continuous wave CW, but a modulated wave that repeats emission and stop).

[0431] Due to the configuration of the radar detection circuit, both the radar adopted in the portable orbiter and the collision prevention system of Mazda cars repeat detection and non-detection while sweeping and stopping. The repetition period is different, for example, between MSSS and the collision prevention system of Mazda cars. Therefore, the state of this detection / non-detection is shaped into a rectangular wave pulse, the period of this pulse is measured, and if it is within a predetermined range, it is determined as a modulated radar wave (MSSS).

[0432] <12-2. Discrimination of Various Other Radar Waves> As a method for discriminating whether a microwave radar is a CW radar, an FMCW radar, or a pulse radar, it may be configured as follows.

[0433] (12-2-1. Discrimination by Confirming Waveform Duration) A. CW Radar (Continuous Wave Radar) This type of radar emits a continuous microwave signal. Therefore, since it emits a continuous signal, the received signal is also continuous. Therefore, when the received signal continuously exists at a certain frequency, the control unit 11 may determine that it is likely to be from a CW radar. B. FMCW Radar (Frequency Modulated Continuous Wave Radar) This radar also emits continuous signals, but the frequency changes with time. Therefore, when the received signal persists at a constant frequency and the frequency changes with time, the control unit 11 may determine that it is likely from an FMCW radar. C. Pulse Radar This type of radar emits short pulses. The received signal also exists at short intervals and is then interrupted. Therefore, when the received signal exists at short intervals and is then interrupted, the control unit 11 may determine that it is likely from a pulse radar.

[0434] (12-2-2. Discrimination by Spectrum Analysis) A. The control unit 11 may perform spectrum analysis on the received signal and determine that it is a CW radar when a peak appears at a certain frequency. B. The frequency of an FMCW radar changes with time. Therefore, when the control unit 11 performs spectrum analysis on the received signal and a spectrum with a spread appears, it may determine that it is an FMCW radar. C. A pulse radar has short pulses. Therefore, when the control unit 11 performs spectrum analysis on the received signal and a spectrum over a wide band appears, it may determine that it is a pulse radar.

[0435] (12-2-3. Discrimination by Time Domain Analysis) The waveform in the time domain of a CW radar appears as a continuous signal with a constant amplitude. Since the frequency of an FMCW radar changes with time, the waveform in the time domain appears as a modulated continuous signal. The waveform in the time domain of a pulse radar appears as short pulses and is interrupted at those intervals. Therefore, the control unit 11 may discriminate the three signals based on the characteristics of these signals.

[0436] (12-2-4. Method for Determining Which Type of Radar the Microwave Received at a Specific Frequency Is From) A. Advanced Signal Processing: Cross Correlation First, prepare and store known template signals of CW, FMCW, and pulsed radars. The control unit 11 calculates the cross-correlation between the received signal and each template signal. Then, the control unit 11 may determine that the template with the highest correlation value indicates the type of the received signal. B. Utilization of Machine Learning Collect a large amount of sample data of CW radars, FMCW radars, and pulsed radars. Then, use these data to train a classification model (e.g., SVM, neural network). And the control unit 11 may input the received signal into this model to obtain a prediction of the radar type. C. Time-Frequency Analysis: Wavelet Transform Wavelet transform is an analysis method that can provide information on both the time and frequency of a signal simultaneously. Since CW, FMCW, and pulsed radars have different time-frequency characteristics, it is advisable to use wavelet transform to identify these characteristics. D. Extraction of Statistical Features The control unit 11 extracts statistical features (e.g., mean, variance, kurtosis, skewness, etc.) from the received signal. Then, the control unit 11 may set criteria or a model for determining from which radar type the received signal is based on these features.

[0437] (12-2-5. When scanning a predetermined frequency band and identifying the signal at the time when the sweep stops) A. Instantaneous Frequency Analysis The control unit 11 analyzes the frequency components of the signal at the time when the sweep stops. Since the frequency of the FMCW radar changes with time, if the frequency variation of the signal at the moment when the sweep stops can be captured, it can be used as a clue for identification. B. Measurement of Signal Duration The control unit 11 measures the duration of the signal at the time when the sweep stops. Since the CW radar emits a continuous signal, if the duration of the signal is long, the possibility of it being a CW radar is high. On the other hand, since the pulse radar emits short pulses, if the duration of the signal is short, the possibility of it being a pulse radar is high. Therefore, the control unit 11 may discriminate whether it is a CW radar or a pulse radar based on the length of the signal duration, that is, whether it is equal to or greater than a set threshold value. C. Detection of Modulation The control unit 11 checks whether there is modulation in the signal at the time when the sweep stops. Since the FMCW radar uses frequency modulation, the control unit 11 can confirm the possibility of the signal being from the FMCW radar by detecting the presence of modulation. D. Utilization of Advanced Signal Processing Techniques The control unit 11 may analyze the signal at the time when the sweep stops using advanced signal processing techniques (e.g., cross-correlation, wavelet transform, spectrogram, etc.) to identify the characteristics and patterns of the signal. E. Utilization of Machine Learning Using the pre-collected sample data of CW radar, FMCW radar, and pulse radar in advance, train a classification model. The control unit 11 may input the signal at the time when the sweep stops into this model to obtain a prediction of the radar type.

[0438] The control unit 11 may be configured to more accurately identify from which type of radar the signal at the time when the sweep stops is by combining the above-mentioned various methods.

[0439] (12-2-6. Analyze the frequency components of the signal at the time when the sweep stops, and basic circuit blocks for identifying pulse wave radar) The detection circuit of the pulse radar may be configured by combining the following circuit elements. A. Band Pass Filter (BPF) A band - pass filter is a filter for scanning a predetermined frequency band. This filter is designed to allow only signals in a specific frequency band where the signal of the pulse radar is expected to exist to pass through. B. Envelope Detector It is a device for extracting the envelope of a pulse waveform. Thereby, the presence and the duration of the pulse can be detected. C. Threshold Detector The threshold detector monitors the output from the envelope detector and detects signals with an amplitude above a specific threshold. Thereby, the actual pulse signal can be distinguished from noise and other unwanted signals. D. Timer Circuit The timer circuit is a circuit for measuring the duration of a pulse. Based on the output from the threshold detector, it detects the start and end of the pulse and measures the time in between. E. Logic Circuit The logic circuit determines whether the duration of the pulse is within a specific range based on the output from the timer circuit. This range is set based on the expected duration of the signal of the pulse radar. F. Output Indicator The output indicator is a circuit that lights an indicator (e.g., LED) when a signal from the pulse radar is detected based on the output from the logic circuit. By using this circuit block, it is possible to identify whether the signal at the time when the sweep stops is from the pulse radar.

[0440] (12 - 2 - 7. Basic Circuit Blocks for Identifying Pulse Wave Radars Using Spectrum Analysis) The detection circuit of the pulse radar may be configured by combining the following circuit elements. A. Analog Front End (AFE) The analog front end amplifies the received signal to an appropriate amplitude level and reduces noise. B. Analog-to-Digital Converter (ADC) The analog-to-digital converter converts an analog signal into a digital signal. There may be a need for a high-speed ADC. C. Fast Fourier Transform (FFT) Block FFT is the core part for performing spectral analysis of digital signals. FFT converts a signal in the time domain into the frequency domain. D. Peak Detector The peak detector analyzes the output from the FFT block and detects peaks in a specific frequency band. Since pulse radars often have strong spectral components in a specific frequency band, this peak detector can be used to identify the signals of pulse radars. E. Threshold Detector The threshold detector determines whether the amplitude of a peak is above a specific threshold. This makes it possible to distinguish actual pulse signals from noise and other unwanted signals. F. Logic Circuit Based on the outputs from the threshold detector and the peak detector, the logic circuit determines whether the signal is from a pulse radar. G. Output Indicator The output indicator is a circuit that lights an indicator (e.g., LED) when a signal from a pulse radar is detected, based on the output from the logic circuit. By using this circuit block, it is possible to identify the signals of pulse radars based on spectral analysis.

[0441] (12 - 2 - 8. Alternative Means for Avoiding High-Speed ADC) A. Subsampling Subsampling is a technique for sampling a signal at a sampling rate lower than the Nyquist frequency. Using this method, high-frequency signals can be sampled at a low sampling rate, but aliasing may occur. Appropriate band-pass filtering can be used to control aliasing. B. Downconversion Downconversion uses an RF mixer to convert a high-frequency signal to a lower intermediate frequency (IF) or baseband. This allows the signal to be sampled using a slower ADC. C. Low-Pass Filtering Low-pass filtering limits the bandwidth of the signal to a range that can be sampled by a slower ADC. This is particularly effective when only specific frequency components of the signal are of interest. D. Time Interval Measurement This is a method of directly measuring the arrival time and interval of pulses by utilizing the characteristics of the pulse radar signal. This eliminates the need to directly sample the frequency content of the signal. E. Non-Uniform Sampling This is a method of sampling only at the necessary times based on the characteristics of the signal. This eliminates the need for continuous high-speed sampling. By appropriately combining these alternative means, it is possible to identify the pulse radar signal without using a high-speed ADC.

[0442] (12-2-9. Method of Identification by Utilizing the Characteristics of Pulse Radar Waves with a Four-Beam Angle Measurement Method Employing Digital Beamforming) A. Beam Separation When using digital beamforming, each beam is focused in a specific direction. By analyzing the signals from the receiving antenna array, the presence of four different beams can be detected. This is a distinct characteristic that differentiates it from other radar types. B. Correlation Analysis Analyze the correlation of signals among the four beams. When using digital beamforming, each beam's signal has a specific directivity, but there may be a correlation of signals caused by reflections from the same target. C. Beam Pattern Analysis By analyzing the radiation patterns and shapes of the four beams, the characteristics of digital beamforming can be identified. In particular, by analyzing characteristics such as the beam width, direction, and degree of overlap, clues for identifying this type of radar can be obtained. D. Analysis of Temporal Beam Variations A radar using digital beamforming can dynamically change the direction of the beam over time. By detecting such dynamic beam variations, the characteristics of digital beamforming can be identified.

[0443] By combining these methods, the control unit 11 can effectively identify a pulsed radar wave with a four-beam angle measurement method employing digital beamforming.

[0444] (12-2-10. Circuit Block for Identifying a CW Wave and a Pulsed Radar Wave with a Four-Beam Angle Measurement Method Employing Digital Beamforming Using Two Microwave Receiving Modules) The circuit block for identifying the pulsed radar wave may be configured by combining the following circuit elements. A. Microwave Receiving Module The two receiving modules receive signals using antennas with different directivities. This helps to detect the beam directivity and pattern. B. Analog Front End (AFE) The AFE amplifies the received signal to an appropriate amplitude level and reduces noise. C. Mixer The mixer mixes the received signal and the local oscillator (LO) signal to generate an intermediate frequency (IF) signal. This reduces the frequency band of the signal and facilitates subsequent processing. D. Envelope Detector The envelope detector extracts the envelope of the IF signal. This enables the detection of the presence and duration of the pulse. E. Correlation Analysis Block The correlation analysis block calculates the correlation of signals from two receiving modules. When digital beamforming is used, the signals of each beam have a specific directivity, but there may be a correlation of signals caused by reflections from the same target. F. Digital Processing Unit (DPU) Based on the outputs from the envelope detector and the correlation analysis block, the DPU determines whether the signal is a CW wave or a pulsed radar wave that employs digital beamforming. G. Output Indicator Based on the output from the DPU, an indicator (e.g., LED or display) that indicates the type of the signal is controlled. By using this circuit block, it is possible to identify a CW wave and a pulsed radar wave with a four-beam angle measurement method that employs digital beamforming using two microwave receiving modules.

[0445] (12-2-11.1 Circuit block for identifying a CW radar wave and a pulsed radar wave with a four-beam angle measurement method that employs digital beamforming using one microwave receiving module and multiple antennas) A. Multi-Antenna Array Multiple antennas are arranged to simultaneously receive signals from different directions. This helps to detect the directivity and pattern of the beam. B. RF Switch A switch for switching the signals from multiple antennas to one microwave receiving module in a time-division manner. C. Analog Front End (AFE) The AFE amplifies the received signal to an appropriate amplitude level and reduces noise. D. Envelope Detector Extracts the envelope of the signal from the AFE. This makes it possible to detect the presence and duration of the pulse. E. Digital Processing Unit (DPU) Based on the output from the envelope detector, it is determined whether the signal is a CW radar wave or a pulse radar wave that employs digital beamforming. Furthermore, the characteristics of digital beamforming are identified by analyzing the correlation of signals from multiple antennas and the timing differences. F. Output indicator Based on the output from the DPU, an indicator (e.g., LED or display) that shows the type of signal is controlled. By using this circuit block, it is possible to identify a CW radar wave and a pulse radar wave with a four-beam angle measurement method that employs digital beamforming using one microwave receiving module and multiple antennas.

[0446] (12-2-12. FMCW and FCM are different) A. FMCW (Frequency Modulated Continuous Wave) FMCW refers to a frequency-modulated continuous wave radar. The FMCW radar irradiates a target while continuously changing the frequency of the transmitted wave. By measuring the frequency difference between the reflected wave and the transmitted wave, the distance to the target is calculated. FMCW radars are used in various applications such as automotive driving assistance systems and drone collision avoidance systems. B. FCM (Frequency Code Modulation) FCM may refer to a modulation method that uses a specific frequency code to transmit information. However, the term "FCM" is not common in the context of FMCW radars.

[0447] [13. Detection operation mode setting function] The control unit 11 of the electronic device 10 is equipped with a [Simple Mode] for those who want to detect only Orbis and give an alarm, although the alarm does not sound easily, and a [Detailed Mode] for those who want to detect the presence of Orbis from a distance and sound various alarms. When the electronic device 10 is first powered on at the factory, the control unit 11 displays a screen for selecting one of the modes. This screen for selecting the mode may be a screen equipped with soft buttons for selecting [Simple Mode] and [Detailed Mode].

[0448] It is preferable that the items and menu screens set in the simple mode and the detailed mode are the same. When the simple mode is selected, the control unit 11 makes settings suitable for detecting only Orbis for each setting item and giving an alarm, while not sounding much for the others. All the menu settings are switched to the settings in the non-sounding direction. Also, when the detailed mode is selected, the control unit 11 detects the presence of Orbis from a distance and makes settings suitable for various alarms to sound. It is a mode in which alarms sound including false alarms.

[0449] If set at the first power-on, in actual use, it may be different from what the initial user had imagined. For example, there may be situations such as "the alarm rings more annoyingly than I thought" or "it's not interesting because it doesn't ring at all". Therefore, it is advisable for the control unit 11 to display [Simple Mode] and [Detailed Mode] again after a predetermined period, for example, three months after the first power-on, and give an opportunity to change the mode.

[0450] Many users often continue to use the device as it is without changing the settings much after setting it once. Also, whether the initial settings are as expected can be understood by using the device for a certain period of time. Therefore, as described above, give an opportunity for reconsideration after a certain period (for example, three months), and then, from the side of the electronic device 10, do not give such an opportunity for reconsideration anymore. For users who are satisfied with the current settings, it would be cumbersome and annoying to get messages for regular reconsideration, but such things will disappear.

[0451] In addition, the control unit 11 may obtain the frequency of false alarms, and if the frequency exceeds a threshold value, provide information for correcting it. Such information may be, for example, to display a QR code (registered trademark) together with a message such as "If there are many false alarms, watch this video" for a certain period of time and then end the display. When the QR code is read using a smartphone or the like, it may be possible to access a website that displays setting items for reducing false alarms when there are many false alarms. The website may be a website prepared by the manufacturer, or may be a YouTube user's website or the like that explains the appropriate setting items for each operation. Also, since it is troublesome for the user to manually perform the setting process while viewing the website, it may be possible to download data for appropriate settings by reading the QR code. Also, on the actual device of the electronic device 10, if some setting is displayed as a QR code and read with a smartphone, it jumps to the manufacturer's website. Then, the setting is recorded in a prescribed database.

[0452] [14. Application to Wireless] In the above-described embodiment, it was stated that the portable orbis such as MSSS or JMA and the laser notification process may have a function of changing the control based on the deployment status and reception characteristics. The same may be done for wireless pre-alarms.

[0453] For example, the wireless frequencies used vary and are determined for each region. For example, in the case of a car stereo, the operating frequency is determined by the region. For example, when receiving a wireless signal with a frequency assigned to a fire helicopter in a region where no fire helicopter is introduced, the control unit 11 may process it as a false alarm. The processing as a false alarm may be, for example, not to sound a wireless alarm or not to give a normal alarm.

[0454] Similar to the deployment status of portable orbits, for example, information on the types of wireless used or not used at the prefecture level may be registered, and an alarm may be controlled based on the registered information. It is advisable to store information indicating that a certain type of wireless among the numerous wireless alarms equipped with a radar detector is not used in this prefecture, or vice versa. It is possible to register the presence or absence of all wireless alarms, but for example, it is advisable to register only the less amount of information.

[0455] Also, it is advisable to prepare data like a frequency table that describes the wireless alarms and the frequencies designated for use for each prefecture, and make it possible to download the frequency table itself together with public regulatory information, etc. Since the wireless frequencies used in each jurisdiction system are publicly available, it is advisable to utilize that information. The wireless frequencies described in this frequency table are used to search for frequencies that should not be used for sounding wireless alarms.

[0456] The output of UHF waves is not extremely large, so there are some that are used only within the jurisdiction range in the jurisdiction system. Therefore, it is not limited to the prefecture level. For example, within the same prefecture, when the location is different and the frequency is different, it is advisable to control by dividing into small areas. Also, the information on the use / non-use and frequency of this wireless should be sent together with information that is distributed for free and has a high update frequency, like public regulatory information. It is advisable to use public regulatory information that is updated daily as it can be reflected immediately.

[0457] In addition, the frequency of the dummy channel of the third harmonic distortion formed by mixing two frequencies of terrestrial digital broadcasting may overlap with the effective radio frequency targeted for radio alerts. In such a case, when receiving the signal of the dummy channel, it may be determined that the radio targeted for a specific radio alert has been received, and the corresponding radio alert may be notified. Therefore, for areas where there are dummy channels with frequencies that match or are close to the frequencies targeted for radio alerts, it is advisable to register information for not being affected by the dummy channel in units of prefectures or in a smaller and narrower range. It is advisable to turn off the notification of radio alerts of the types affected by the dummy channel for each such area.

[0458] By doing so, when the control unit 11 receives a radio at the same frequency as the dummy channel, it performs a process of not issuing a normal radio alert, and can suppress the occurrence of false alarms. For the information registered for performing such control, it is advisable to use the frequency of the dummy channel, information specifying the types of radio alerts affected, and the like.

[0459] The frequency of the dummy channel and the area it affects can be determined based on the frequency of terrestrial digital broadcasting and the positional relationship of relay stations of neighboring terrestrial digital broadcasters. For example, between NHK Tokai TV and Nagoya Broadcasting, a dummy channel of 350.1 MHz is formed due to their overlap. Therefore, for example, in the whole area of Aichi Prefecture or in the area affected by the dummy channel of steam, it is advisable not to perform normal notification for radio alerts corresponding to 350.1 MHz.

[0460] [15. Modification Example] The present invention is not limited to the above-described embodiments, and can be appropriately changed without departing from the gist. The following is an example of a modification of the present invention.

[0461] (15-1) In each of the above-described embodiments, a radar / laser detector capable of detecting both the enforcement wave using radar and the enforcement wave using laser was taken as an example, and the detection function of the enforcement wave using radar was described. However, the detection function of the enforcement wave using laser does not necessarily have to be provided.

[0462] (15-2) The electronic device 10 may not have a part of the configuration described in each of the above-described embodiments. For example, as long as at least one of the above-described problems is improved, the configuration described so far, for example, a part of the configuration of the hardware element or the software element, may be omitted from the electronic device 10.

[0463] (15-3) Addition of restricted speed The control unit 11 identifies the road on which the vehicle is traveling from the current position information. When the identified road is a highway, a national road, a prefectural road, or a main living road, the control unit 11 acquires the maximum speed of the road during travel and may display a maximum speed icon indicating the maximum speed at a predetermined position on the display unit. The maximum speed icon may be, for example, an icon imitating a speed sign.

[0464] (15-4) The electronic device 10 stores and holds information on connecting roads such as ICs and JCTs. The control unit 11 takes into account the stored information on connecting roads to surely recognize whether the vehicle is traveling on a highway. For example, when the control unit recognizes that the current position of a vehicle traveling on a general road has passed through a connecting road, the control unit forcibly transfers the position of the vehicle to the highway. Thereby, even in an environment such as Nagoya IC, for example, the problem of becoming a general road can be solved.

[0465] [16. Another embodiment] From FIG. 11 onwards, another form of the electronic device 10 is shown. This electronic device 10 has, similar to the above-described embodiments, a GPS warning based on position information, a function of receiving and warning radar waves of the X band and the K band, and a function of receiving and warning laser light. And the shape of the main body 101 of the electronic device 10 in this embodiment is different.

[0466] <16-1. Background of the invention> Conventionally, the shape of the housing has been rectangular as shown in FIGS. 2 and 5 etc. in order to be simple, and even if the periphery is R-processed, each surface is made flat. Further, in accordance with the requirements for miniaturization and thinning, when the layout of the components and substrates housed in the housing 1011 is determined, the dimensional shape of the housing 1011 is designed so that the inner surface of the housing 1011 approaches the components and substrates housed in the housing 1011. Also, each component that receives radio waves or laser light flying in from the outside is arranged inside the housing 1011, that is, near the inner surface. These components include, for example, an antenna (e.g., a patch antenna) that receives radar waves, a GPS antenna that receives GPS signals, a lens that receives laser light, and the like. And these components are arranged in a layout close to the inner surface of the housing 1011.

[0467] On the other hand, in the conventional design, it has been found that sufficient sensitivity cannot be obtained to receive radar waves from the vehicle speed measurement value using microwaves in the K band such as MSSS. This can be presumed to be due to the short distance from the patch antenna to the inner surface of the housing 1011 facing it. That is, since the housing 1011 is generally a dielectric formed from resin, it can be presumed that the impedance affects the resonance frequency of the antenna, causing the wavelength of the microwave output from the antenna to be distorted.

[0468] Furthermore, the radar wave output from MSSS has a small radio wave intensity, and combined with the fact that in a superheterodyne receiver circuit, the detection process in the K band uses the second harmonic of the local oscillator, the radar wave from MSSS may not be detected unless it is close to MSSS. Therefore, a new problem of wanting to increase the reception sensitivity of the radar wave in the K band has been found.

[0469] That is, the radar wave emitted from a conventional vehicle speed measurement device using the X band has a large radio wave intensity. Therefore, even though there is a sensitivity decrease due to the patch antenna approaching the inner surface of the housing 1011 as described above, the radar wave in the X band could be received without problems, so the above problem did not become apparent. Therefore, as described above, the design of the dimensional shape of the housing 1011 has been focused solely on miniaturization and thinning.

[0470] And in order to be able to detect the radar wave from the vehicle speed measurement device in the K band as well, the housing 1011 that was designed and used in an electronic device corresponding only to the conventional X band was used, and the receiving circuit for microwaves such as the oscillation frequency of the local oscillator of the patch antenna was designed so that the K band could also be supported and implemented as it was. Then, as described above, it was found that the reception sensitivity in the K band may be insufficient. And based on the new problems described above, the inventors of the present invention invented various solutions shown below.

[0471] <16-2. Configuration of the electronic device 10>

[0472] (16-2-1. Basic configuration of the housing 1011) FIG. 11 is a diagram showing the external configuration of the main body 101. FIG. 11(A) is a view of the main body 101 seen from the upper right diagonal direction on the front side. FIG. 11(B) is a view of the main body 101 seen from the upper left diagonal direction on the back side. Also, FIGS. 12 to 16 show six views of the main body 101. FIG. 12 is a front view of the main body 101, FIG. 13(A) is a right side view of the main body 101, FIG. 13(B) is a left side view of the main body 101, FIG. 14 is a back view of the main body 101, FIG. 15 is a plan view of the main body 101, and FIG. 16 is a bottom view of the main body 101.

[0473] The main body part 101 has a housing 1011. The housing 1011 is a flat box shape that is longer in the left - right direction than in the up - down direction and has a relatively small thickness. The housing 1011 is formed of, for example, resin or other materials. The housing 1011 has a first case 1014 and a second case 1015 that are divided into two parts in the front - rear direction. The first case 1014 and the second case 1015 have one side open, and the tips of the open sides are joined together to form a hollow box - shaped housing 1011. The first case 1014 is located on the front side of the housing 1011 and is provided with a rectangular opening that is longer in the left - right direction than in the up - down direction. The main body part 101 has a display part 13 for displaying an image at the position of this opening, and a touch sensor 191 superimposed on the display area of the display part 13. The main body part 101 has an illuminance sensor window 201 and a light - emitting part 24 at a position on the left side of the display part 13 on its front side. The light - emitting part 24 has a light - emitting area with the longitudinal direction in the up - down direction. A memory - medium insertion port is provided on the right side surface of the housing 1011. Through this memory - medium insertion port, a memory medium 50 is attached to the main body part 101. The memory medium 50 is, for example, an SD card. The SD card includes any of the shapes such as an SD memory card, a miniSD card, and a microSD card. Thus, the configuration of the first case 1014 is the same as that of the embodiment shown in FIG. 2.

[0474] On the back side of the housing 1011, a second case 1015 is located. At a predetermined position of this second case 1015, a lens holder 1012 is provided. The lens holder 1012 is a through-hole that penetrates the inside and outside of the housing 1011 and holds a lens 121. The lens 121 is a condensing lens. In this embodiment, the lens 121 is an aspherical lens (spherical lens) having an elliptical shape that is longer in the left-right direction than in the up-down direction and has an aspherical light incident surface, but other condensing lenses may be used. Near the lower end on the back side of the housing 1011 and near the center in the left-right direction of the housing 1011, a mounting portion 1013 is provided. The mounting portion 1013 is a portion where a fixing portion (bracket: not shown) for attaching the main body portion 101 to the vehicle is attached. On the back side of the housing 1011, further, a power switch 221 for switching on / off the power of the electronic device 10 and a terminal portion 23 for connecting an external device are provided. The configuration up to this point is basically the same as that of the embodiment shown in FIG. 2.

[0475] The second case 1015 has a protruding portion 1017 that protrudes outward in a region below the center of the back surface 1016. As shown in FIG. 17, when viewed from the inner surface side of the second case 1015, this protruding portion 1017 becomes a recessed portion 1018 that is recessed outward. The depth of this recessed portion 1018 is made equal to the amount of protrusion of the protruding portion 1017 from the back surface 1016. Thereby, the inner surface of the second case 1015 has a shorter distance from the parts and substrates housed in the housing 1011 in the region where the protruding portion 1017 (recessed portion 1018) is not formed, and in the region where the protruding portion 1017 is provided, the distance becomes longer by the depth of the recessed portion 1018 compared thereto.

[0476] (16 - 2 - 2. Parts and Substrates Mounted in the Housing 1011) As shown in FIGS. 18 to 20, inside the first case 1014, a main board 1031 is mounted, and various compone...
