Description

[Technical field]

[0001] The present invention relates to a system, a program, and the like. [Background technology]

[0002] Patent Documents 1 and 2 disclose electronic devices that receive microwaves emitted from a vehicle speed enforcement device and output an alarm if they detect the presence of the vehicle speed enforcement device. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2008-64588 A [Patent Document 2] JP 2017-96728 A Summary of the Invention [Problem to be solved by the invention]

[0004] An object of the present invention is to provide a technique relating to vehicle speed control.

[0005] The purpose of the present invention is not limited to this, and the applicant intends to obtain rights for configurations that aim to obtain effects from parts of the configurations disclosed in this specification and drawings, etc., by filing a divisional application, amendment, etc. For example, this specification discloses a problem in which the part described as "can be" in this specification is read as "the problem is to be". The problems are described as being independent, and the applicant intends to obtain rights for the configurations for solving each problem separately by filing a divisional application, amendment, etc. Even if the problems are implicitly understood from the description in the specification, the applicant intends to include part of the configurations described in this specification in the scope of the patent claim by amendment or divisional application. In addition, the applicant has disclosed a configuration that solves a problem that combines these independent problems, and intends to obtain rights for it. [Means for solving the problem]

[0006] (1) A system is provided that is provided in a vehicle and has a control unit that performs alarm control to warn of approach to a location where a speed enforcement device is attached.

[0007] In this way, the user can be made aware of the approach of a location where a speed control device is installed and where control may take place.

[0008] In particular, it is preferable that the speed control device performs an alarm control to warn of approach to the "installation point of the detachable fixed part", and the content of this alarm should not be an alarm indicating approach to the speed control device, but an alarm indicating approach to the location of the fixed part where the speed control device can be installed. For example, instead of "500m ahead, there is an ORBIS. Watch your speed!", it is preferable to warn "500m ahead, there is a pole where the ORBIS can be installed. Watch your speed!" or "500m ahead, there is a semi-fixed ORBIS pole. Watch your speed!". Although "500m ahead, there is a location where the ORBIS can be installed. Watch your speed!" is also acceptable, it is preferable to provide a specific structure such as "500m ahead, there is a pole where the ORBIS can be installed. Watch your speed!", and in particular, to provide a structure indicating at least a part of the fixed part. In this way, it becomes possible for the user to focus on the structure, pay attention to the location, and easily check whether or not the speed control device was actually installed on the fixed part. The warning contents may be stored in the storage means of the system and may be output by voice, text, image, etc. Conventional systems store the location of the speed enforcement device itself and issue a warning indicating the approach to the speed enforcement device, but in the case of a semi-fixed speed enforcement device, such as a semi-fixed speed enforcement device, in which a detachable fixed part is installed in advance on the shoulder of a road, and whether or not the speed enforcement device is installed on the fixed part is changed as needed, the inventors have found that it is inappropriate to issue a warning indicating the approach to the speed enforcement device as the warning contents. The installation position of the fixed part is investigated and grasped in advance, and the position information of the fixed part is associated with information indicating that it is a fixed part and stored in the storage means, and the system determines whether or not to issue the warning based on the position information of the fixed part and the information indicating that it is a fixed part. The speed enforcement device may be one that is equipped with at least a vehicle speed measurement unit, and may further be equipped with an imaging unit that images a vehicle that is exceeding the speed limit.

[0009] (2) The control unit may perform warning control to warn of approach to the installation location based on position information of the installation location of the fixed part and position information of the vehicle.

[0010] In this way, the user can be made aware of the approach of a location where a speed control device is installed and where control may take place.

[0011] In particular, instead of the installation location of the speed enforcement device as in the past, it is preferable to perform an alarm control to notify the approach to the installation location based on the location information of the "installation location of the detachable fixed part" of the speed enforcement device and the location information of the vehicle. For example, it is preferable to store the locations of the posts installed on routes such as urban expressways to install semi-fixed speed cameras, and to perform control to issue an alarm to notify the approach of the location of the post for installing semi-fixed speed cameras when each post is approached.

[0012] (3) The fixed unit may have at least one of a power supply unit that supplies power to the speed enforcement device and a line unit through which the speed enforcement device communicates.

[0013] In this way, the user can know locations where speed enforcement devices are installed and enforcement may be carried out, based on the installation location of a fixed unit that has a power supply unit or line unit for operating the speed enforcement device.

[0014] (4) When it is determined that the speed enforcement device is installed in the fixed part, the control unit may perform a first warning control.

[0015] In this way, if a speed control device is actually installed, the user can be made aware of this.

[0016] In particular, after issuing an alarm indicating the approach to the installation point of the fixed part based on location information of the installation point of the fixed part to which the speed enforcement device is detachable and on location information of the vehicle, rather than the installation point of the speed enforcement device, if it is determined that a speed enforcement device is installed on the fixed part on the way to the installation point of the fixed part, an alarm indicating the approach to the speed enforcement device may be issued. This further alarm indicating the approach to the speed enforcement device may be an alarm simply indicating the reception of a speed measurement signal from the speed enforcement device, but may in particular be an alarm indicating that a speed enforcement device is installed on the fixed part. For example, the positions of posts installed on routes such as urban expressways to install semi-fixed speed cameras as speed enforcement devices are stored, and when approaching each post, an alarm is issued to the effect that the position of a post for installing a semi-fixed speed camera is being approached (for example, an alarm saying "Approaching a post where a semi-fixed speed camera can be installed!"), and if a speed measurement signal is received before reaching the position of the post that issued the alarm, an alarm may be issued simply to the effect that a speed measurement signal has been received, saying "Enforcement laser has been received." However, it is also possible to issue an alarm with content that indicates that a speed enforcement device is present in the fixed part, such as "There is an speed camera on a post where a semi-fixed speed camera can be installed! Watch your speed!", or an alarm that includes content that indicates that a speed enforcement device is present in the fixed part and content that a speed measurement signal has been received, such as "There is an speed camera on a post where a semi-fixed speed camera can be installed! Laser received! Watch your speed!". The speed measurement signal is a signal for speed measurement emitted by a speed enforcement device, and may also be called a measurement wave for speed enforcement.

[0017] The determination that a speed enforcement device is installed on the fixed part may be made by detecting the reception of radio waves, light, etc. for measuring the vehicle speed. For example, if a laser from a laser-type speed camera is detected after a warning of approach to the post position, a warning may be issued to indicate that a semi-fixed speed camera is present on the post. The determination that a speed enforcement device is installed on the fixed part may also be made when it is recognized that a speed enforcement device is shown in an image captured by a camera. In particular, it may be made when the position of the camera image corresponding to the position of the fixed part is identified and a speed enforcement device is shown in the vicinity of the identified position. For example, if a camera detects that a semi-fixed speed camera is installed on the post while approaching the post position, a warning may be issued to indicate that a semi-fixed speed camera is present on the post.

[0018] The distance at which the approach warning is issued when the vehicle approaches the fixed part within a certain distance should be set to a distance longer than the reach of the speed measurement signal of the speed enforcement device fixed to the fixed part. For example, if the speed enforcement device measures the vehicle speed using a laser, the distance should be set to a distance longer than the reach of the laser. For example, if the reach of the laser is 200 m, the approach warning to the fixed part should be set to a distance longer than 200 m, such as 500 m.

[0019] (5) The speed enforcement device may have a receiving unit that receives a measurement wave velocity measurement signal emitted by the speed enforcement device, and the control unit may perform the first alarm control when the measurement wave velocity measurement signal is received.

[0020] In this way, an alarm is issued upon receipt of a measurement wave speed measurement signal from a speed enforcement device, so that the user can more accurately be made aware of the presence of a speed enforcement device.

[0021] (6) The control unit may perform the first warning control when the speed enforcement device or a predetermined signboard installed at a speed enforcement location is recognized from an image captured in front of the vehicle.

[0022] In this way, even if a measurement wave velocity measurement signal is not received from a speed enforcement device, the user can obtain information about the location where the speed enforcement device is installed.

[0023] (7) The control unit performs a second warning control when the position information of the vehicle is in a predetermined proximity relationship with the position information of the installation point registered in a database.

[0024] In this way, it is possible to notify the user of information about locations where speed enforcement devices may be installed, based on the results of actually driving in the vicinity of those locations.

[0025] (8) When it is determined that the speed enforcement device is not fixed to the fixing part, the control part may perform the second warning control.

[0026] In this way, the user can be made aware of information about locations where enforcement may take place, even if enforcement devices are not currently installed.

[0027] (9) The control unit performs the second warning control when the fixed portion is recognized from an image captured in front of the vehicle.

[0028] In this way, the user can grasp information about locations where enforcement may take place based on images captured from the vehicle.

[0029] (10) The control unit does not perform the second warning control when the speed control device or a predetermined signboard installed at a speed control point is not recognized from an image captured in front of the vehicle. It is advisable to do so.

[0030] In this way, speed enforcement devices and designated signs are installed at speed enforcement points, and an alarm is sounded if these are included in an image captured from the vehicle, so that the user can be made aware that a speed enforcement device is actually installed.

[0031] (11) The control unit may perform control to register location information corresponding to the installation location of the fixed unit in a database in which location information corresponding to the installation location collected from each of a plurality of vehicles is registered, and may perform the second alarm control based on the location information registered in the database and location information of the vehicle.

[0032] In this way, an alarm can be issued in response to changes in the location of speed checkpoints.

[0033] (12) If the speed enforcement device is not fixed to the fixing part, the control part may register information to that effect in the database.

[0034] In this way, an alarm can be issued in response to changes in the location of speed checkpoints.

[0035] (13) The control unit registers in the database information identifying the time when the presence of the fixed part was confirmed in the location information of the installation point of the fixed part, and when the location information of the vehicle is in a predetermined proximity relationship with the location information of the installation point of the fixed part, the time being within a predetermined period going back from the current time, the control unit performs control to issue a second alarm.

[0036] This allows the user to know with greater accuracy that he or she is approaching the installation point of the fixed part.

[0037] (14) The control unit may perform a process of posting to other devices that a speed control device is not installed on the fixed unit.

[0038] In this way, it is possible to make other devices aware that no speed enforcement device was installed in the fixed section. It is preferable to provide a function for posting to other devices that no speed enforcement device was installed in the fixed section. For example, it is preferable to provide a function for posting that no speed enforcement device was installed on the support pole. It is also possible to issue an approaching speed enforcement warning for fixed sections that have recently been posted to have a speed enforcement device installed in the fixed section. For example, it is preferable to issue an approaching speed enforcement warning for those that have recently been posted to have a speed enforcement device installed on the support pole. It is preferable to provide another device (e.g., a server, etc.) that estimates the next movement time and movement location based on the installation period for each location where a speed enforcement device is installed in the fixed section and transmits the information to this device. For example, it is preferable to estimate the next movement time (and movement location) based on the installation period for each location where a speed enforcement device is installed on the support pole and transmit the information to this device from the server, etc.

[0039] (15) If the installation location of the fixed part or the installation location of the speed enforcement device is located on or beyond a curve, the control unit may perform control to notify the driver of this and to warn of the driver's approach to the installation location.

[0040] In this way, the user can grasp information about the installation location of the fixed part even on a curved route with poor visibility.

[0041] (16) The control unit may perform a third alarm control to issue an alarm including a notification of the type of speed enforcement device.

[0042] In this way, the user can understand the type of speed control device.

[0043] (17) The speed enforcement device may have a receiving unit that receives a measurement wave velocity measurement signal emitted by the speed enforcement device, and the control unit may suppress control to issue an alarm when the fixed portion is recognized from an image taken of the front of the vehicle and the measurement wave velocity measurement signal is not received by the receiving unit.

[0044] In this way, since a fixed portion exists but no speed control is being carried out, it is possible to prevent the provision of unnecessary information to the user.

[0045] (18) The vehicle has a receiving unit that receives a speed measurement signal emitted by the speed enforcement device, and when the fixed part is recognized from an image taken of the front of the vehicle and the speed measurement signal is not received by the receiving unit, the control unit issues an alert to the effect that it is highly likely that the speed enforcement device was not operating.

[0046] In this way, the user can be made aware that it is highly likely that the speed enforcement device was not in operation at the installation location. For example, if a speed enforcement device is detected to be installed at the fixed part from an image captured in front of the vehicle by a camera, but a speed measurement signal is not received, a notification may be issued indicating that it is highly likely that the speed enforcement device was not in operation. For example, if a laser-type semi-fixed speed camera is recognized to be installed on a post from the image from the camera, but the laser is not received, a notification may be issued indicating that it is highly likely that the speed enforcement device was not in operation, such as "There was a laser-type semi-fixed speed camera on the post, but the laser was not detected. It appears to be out of operation."

[0047] (19) The control unit may determine an attribute of a road on which the vehicle is traveling, and if the attribute of the road is a predetermined attribute, perform a fourth warning control to warn of a speed difference of the vehicle.

[0048] In this way, when the road attributes are predetermined attributes, a notification can be given to encourage the user to drive more safely. It is possible.

[0049] (20) It is preferable that the system has an attribute of zone 30 for the road.

[0050] In this way, it is possible to send an alert even in Zone 30, a place where people tend to think that no enforcement will take place.

[0051] (21) There is provided a program for causing a computer to realize the functions of the control unit of any of the above systems.

[0052] This allows the user to know locations where speed enforcement devices are installed and enforcement may take place.

[0053] The inventions shown in (1) to (20) above can be arbitrarily combined. For example, it is preferable 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 shown in (1). In particular, it is preferable to add at least a part of the configuration of at least one of the inventions after (2) to the invention shown in (1). In addition, it is also possible to extract any configuration from the inventions shown in (1) to (20) and combine the extracted configurations. The applicant of this application intends to obtain rights to the inventions including these configurations. In addition, even if there is a description such as "in the case of" or "when", it is not intended to describe the configuration as being limited to that case or time. These are examples of better configurations, and the applicant intends to obtain rights to configurations other than these cases or times. In addition, the parts described in order are not limited to this order. Configurations in which some parts have been deleted or the order has been changed are also disclosed, and the applicant intends to obtain rights. Effect of the Invention

[0057] Hereinafter, the embodiments will be described in detail with reference to the drawings. The embodiments shown below are examples of the embodiments of the present disclosure, and the present disclosure is not limited to these embodiments. In the drawings referred to in the present embodiment, the same parts or parts having similar functions are given the same or similar symbols (symbols with A, B, etc. added after the numbers), and repeated explanations may be omitted. In addition, in each figure referred to in the following description, the scale may be different from the actual scale in order to make each member, each area, etc. recognizable. Hereinafter, a case will be described in which the system of the present disclosure is applied to a system mounted on a vehicle and detects a speed enforcement device. The vehicle may be an 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 with four or more wheels.

[0058] [1. First embodiment] <1-1. Configuration> FIG. 1 is a diagram showing a configuration of a system according to a first embodiment. An electronic device 10 is an electronic device to which the system according to the present disclosure is applied. The electronic device 10 is a detector that receives a laser light emitted by a speed enforcement device 30 as a speed measurement signal measurement wave and detects the speed enforcement device 30. The speed measurement signal is a signal for speed measurement emitted by the speed enforcement device, and may be called a measurement wave for speed enforcement. The appearance of the speed enforcement device shown in FIG. 1 is one example, and may have a different appearance. The laser light is a pulse laser with a specific wavelength of light and a specific pulse width. The specific wavelength belongs to, for example, an infrared light region, and is, for example, any of 850 nm, 905 nm, 950 nm, and 1900 nm. The pulse width is, for example, approximately 20 ns or approximately 15 ns. The pulse interval is, for example, approximately 80 ms. The word "approximately" may be within a predetermined range that can be regarded as being the same as a reference value or substantially the same as the reference value.

[0059] The electronic device 10 is, for example, a monitor-type device having a substantially rectangular parallelepiped shape. The electronic device 10 is installed in the passenger compartment of a vehicle 40. The electronic device 10 is installed on a dashboard 41 using, for example, double-sided tape. An opening is provided on the front side of the electronic device 10. The electronic device 10 has a display unit 13 for displaying an image at the position of this opening. The housing of the electronic device 10 is formed of resin or other materials.

[0060] The speed enforcement device 30 is installed at a speed enforcement point, which is a point where the speed of a vehicle is enforced. The speed enforcement point is determined taking into consideration the vehicle's driving conditions (e.g., whether vehicles are likely to speed) and the occurrence of traffic accidents (e.g., points where a high number of accidents occur). An example of a speed enforcement point is a curve or a point beyond a curve on a route (road) on which a vehicle is traveling. The speed enforcement device 30 is also called a semi-fixed laser orbis, and is installed on a fixed unit 50 that is installed on the shoulder of routes such as urban expressways and other expressways. The fixed unit 50 is, for example, a support pole on which the speed enforcement device 30 is installed. However, the form of the fixed unit 50 as a structure is not limited to this.

[0061] When the speed enforcement device 30 is installed, the fixed unit 50 provides functions necessary for the operation of the speed enforcement device 30. The fixed unit 50 has, for example, a power supply unit 51 and a line unit 52. The power supply unit 51 supplies power for operation to the speed enforcement device 30. The power supply unit 51 is connected to the speed enforcement device 30 by a wire to supply power, but may also supply power wirelessly. The line unit 52 connects the speed enforcement device 30 to a specified communication line. The communication line may be, for example, a network of a specified communication method or a dedicated line.

[0062] As shown in FIG. 2, when the speed enforcement device 30 is fixed to the fixed part 50, the installation point of the fixed part 50 becomes a speed enforcement point. As shown in FIG. 3, when the speed enforcement device 30 is not fixed to the fixed part 50, the installation point of the fixed part 50 is not a speed enforcement point at that time. In this way, the fixed part 50 is installed at a point where vehicle speed enforcement may be carried out or a candidate point for speed enforcement. The signboard 60 shown in FIG. 2 is a signboard that may be installed at a speed enforcement point, and is installed, for example, a predetermined distance (for example, 1 to 2 km) before the installation point of the speed enforcement device 30 in the driving direction (forward direction) of the road.

[0063] The speed enforcement device 30 includes a speed measurement unit 31, an imaging unit 32, and a strobe 33. The speed measurement unit 31 measures the speed of the vehicle, for example, by a laser scanning method. Specifically, the speed measurement unit 31 emits a laser light Lout, and when the laser light Lout reaches the vehicle 40 and is reflected, receives the reflected light Lref. The speed measurement unit 31 measures the distance to the vehicle 40 based on the time required from emitting the laser light Lout to receiving the reflected light Lref. The speed measurement unit 31 repeatedly measures the distance to the vehicle 40, and measures the speed of the vehicle 40 based on the moving distance of the vehicle 40 per unit time. The speed measurement unit 31 emits the laser light Lout within a sector-shaped range T with a central angle of angle θ, for example, while changing the direction in a counterclockwise direction. The emission direction of the laser light Lout is, for example, approximately horizontal. The speed measurement unit 31 emits the laser light to a mirror rotating at a constant speed, for example. The laser light reflected by the mirror and emitted from the light emitting window is the laser light Lout.

[0064] The imaging unit 32 captures an image of the target vehicle when the speed measured by the speed measurement unit 31 is equal to or greater than a threshold value. The imaging unit 32 is used to capture an image of a vehicle that has violated the speed limit. The strobe 33 emits light when the imaging unit 32 captures an image. The imaging unit 32 may capture an image based on light in the infrared region so that the imaging unit 32 can capture an image even at night. In this case, the strobe 33 may emit light having energy in the infrared region. The speed enforcement device 30 transmits data related to speed enforcement, such as the measured speed and the captured image, to an external computer via the line unit 52.

[0065] FIG. 4 is a block diagram showing an electrical configuration of the electronic device 10. Note that the imaging device 70 is a configuration related to the second embodiment and is omitted in this embodiment. The control unit 11 controls each unit of the electronic device 10. The control unit 11 is, for example, a computer including an arithmetic processing circuit and a memory. The arithmetic processing circuit includes, for example, a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other arithmetic processing circuits. The memory includes, for example, a random access memory (RAM) or other volatile memory. The arithmetic processing circuit performs various controls by temporarily reading data into the memory and performing arithmetic processing.

[0066] The light receiving unit 12 is an example of a receiving unit that receives a speed measurement signal (measurement wave). The light receiving unit 12 receives light incident through a window provided on the back side of the electronic device 10, and outputs a signal corresponding to the received light to the control unit 11. The window may be provided with an optical member such as a visible light cut filter or a lens. The signal output by the light receiving unit 12 changes, for example, according to the amount of light received by the light receiving unit 12. The light receiving unit 12 includes, for example, a photodiode as a light receiving element, but may also be a phototransistor or other light receiving element. The light receiving unit 12 has sensitivity at least in the infrared light region. The light receiving unit 12 may include an A / D conversion circuit or the like that converts an analog signal from the light receiving element into a digital signal.

[0067] The display unit 13 displays an image. The display unit 13 is, for example, a 3.2-inch color TFT liquid crystal display. The display unit 13 may be an organic EL display or other display device. The speaker 14 outputs sound. The microwave receiver 15 includes an antenna and a receiving circuit, and receives microwaves. The microwave receiver 15 also has a function of receiving radio waves (for example, microwaves) from a speed enforcement device compatible with a radar system. The GPS (Global Positioning System) receiver 16 includes an antenna and a receiving circuit, and receives signals from GPS satellites. The GPS receiver 16 processes the received signals and outputs position information. The position information includes, for example, latitude information and longitude information, and may further include altitude information. The position information is position information indicating the current position of the electronic device 10, but it is preferable to consider it as position information indicating the current position of the electronic device 10. The communication unit 17 communicates with an external device. The communication unit 17 performs wireless communication, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), or other methods.

[0068] The storage unit 18 stores data. For example, the storage unit 18 stores programs for the control unit 11 to perform various controls. The control unit 11 reads the programs from the storage unit 18 into a memory and executes them. The storage unit 18 also stores map data showing a map, data showing the types and locations of various facilities, data for notifying the presence of an object to be alerted, data for implementing a route guidance function, and the like. Objects that may be subject to an alarm include, for example, locations of accidents caused by drowsy driving, speed enforcement devices (radar type, loop coil type, H system, LH system, photocell type, mobile type, etc.), speed limit change points, enforcement areas, checkpoints, parking monitoring areas, N systems, traffic monitoring systems, intersection monitoring points, signal ignoring prevention systems, police stations, areas with frequent accidents, areas with frequent vehicle thefts, sharp / continuous curves (expressways), branching / merging points (expressways), advance ETC lane guidance (expressways), service areas (expressways), parking areas (expressways), highway oases (expressways), smart interchanges (expressways), gas stations inside PAs / SAs (expressways), tunnels (expressways), highway radio receiving areas (expressways), prefectural border announcements, roadside stations, and view point parking areas. The storage unit 18 stores the type information of these alarm objects, position information indicating their positions, image data (for example, schematic diagrams or photographs) to be displayed on the display unit 13, and audio data in association with each other.

[0069] The storage unit 18 has a database 181 that accumulates location information of the installation point of the fixed unit 50. The location information accumulated in the database 181 may be information already accumulated at the stage of product shipment of the electronic device 10, or location information distributed by a server device of a predetermined business operator, as described later.

[0070] The storage unit 18 may include a storage medium that permanently stores data. The storage unit 18 may include, for example, an optical recording medium, a magnetic recording medium, a semiconductor recording medium, or other recording media. The data stored in the storage unit 18 may be stored in cloud computing or other external storage means as appropriate.

[0071] The operation unit 19 accepts operations by the user. The operation unit 19 includes, for example, a touch sensor, a volume adjustment button, and a work button. The touch sensor is provided on the surface of the display unit 13 and detects a position touched by the user. The volume operation button is operated to adjust the volume of the sound output from the speaker 14. The work button is a button for performing various tasks.

[0072] The sensor unit 20 includes various sensors. The sensor unit 20 includes, for example, a geomagnetic sensor, an acceleration sensor, and an illuminance sensor. The geomagnetic sensor detects geomagnetism to detect which direction north is relative to the direction of travel. The acceleration sensor detects the acceleration of the vehicle in the forward / backward, left / right, and up / down directions. The illuminance sensor detects the illuminance indicating the brightness inside the vehicle cabin.

[0073] The mounting unit 21 is a mounting unit into which an external storage medium is mounted, and the external storage medium is, for example, a memory card. In this case, the mounting unit 21 is a memory card slot. Data stored in the memory unit 18 may be imported via the external storage medium. This data includes update information on new alarm targets (location information such as longitude and latitude, type information, etc.).

[0074] The power supply unit 22 supplies the power supplied from the power source to each unit in the electronic device 10. The power supply unit 22 includes, for example, a power switch and a DC jack. The DC jack is for connecting a cigarette plug cord, and is connected to a cigarette lighter socket of a vehicle via the cigarette plug cord to receive power. The power switch is a switch for turning the power of the electronic device 10 on and off.

[0075] The light emitting unit 23 emits light in various colors and includes, for example, a light emitting diode.

[0076] The cable terminal unit 24 is a terminal to which an external connection cable is connected. For example, the connection cable is a cable that connects the electronic device 10 to an OBD-II connector mounted on a vehicle. The OBD-II connector is also called a fault diagnosis connector, and is connected to the ECU of the vehicle to output various vehicle information.

[0077] In addition to the above, the electronic device 10 may have the functions of a well-known laser detector or radar detector. For example, there are many types of speed enforcement devices, such as fixed types and mobile types. Mobile types include portable types and types mounted on vehicles. The electronic device 10 may have a function of receiving laser light from such speed enforcement devices other than semi-fixed types and issuing an alarm.

[0078] <1-2. Operation> The operation of this embodiment will be described. Fig. 5 is a flowchart showing the operation of the control unit 11 of the electronic device 10. When the operation of the electronic device 10 starts, the control unit 11 executes the process described below. There is no particular limit to the trigger for starting the operation of the electronic device 10, but it is preferable to use, for example, the power supply of the electronic device 10 being turned on or the start of execution of a route guidance function in a navigation function as the trigger.

[0079] <1-2-1. Alarms based on receiving laser light> The control unit 11 acquires a signal from the light receiving unit 12 (step S1). Next, the control unit 11 judges whether or not laser light has been received based on the acquired signal (step S2). The control unit 11 may judge whether or not laser light has been received based on the pulse width, pulse interval, pulse number, wavelength, waveform, and other characteristics. If the judgment in step S2 is "YES", the control unit 11 performs control to warn of approach to the speed enforcement device 30 (first warning control) (step S3). The first warning control may be performed by a method that allows the user to recognize the presence of the speed enforcement device 30, and for example, at least one of outputting a sound, displaying a warning screen on the display unit 13, and controlling the light emission of the light emitting unit 23 is used. Note that in this embodiment, the warning is intended to notify the user of the presence of a speed enforcement point or a point where the fixed unit 50 is installed.

[0080] FIG. 6 is a diagram showing an example of an alarm screen. The alarm screen shown in FIG. 6 is a screen in which a window W1 is arranged so as to be superimposed on a map screen M1. The control unit 11 issues an alarm by displaying the window W1 superimposed on a map M. The map M is specified based on map data and position information from the GPS receiving unit 16. An icon I indicating the position of the vehicle 40 (the vehicle's position) is arranged on the map M. The vehicle's position is specified based on the position information from the GPS receiving unit 16. Note that the icon in this embodiment may be replaced with a character, a symbol, a figure, or another object.

[0081] In the example shown in FIG. 6(A), the window W1 displays a message indicating the presence of a speed enforcement device 30, saying "This is a speed enforcement point." The control unit 11 may also output a voice saying "This is a speed enforcement point" from the speaker 14. When the control unit 11 can determine the type of speed enforcement device (e.g., semi-fixed, fixed, mobile) based on the characteristics of the received laser wave signal or other methods, it may perform control to issue an alarm including a notification of the type of speed enforcement device (an example of a third alarm control). For example, as shown in FIG. 6(B), the control unit 11 may notify with a message saying "This is a semi-fixed speed enforcement point." For example, a fixed or mobile speed enforcement device is an example of a speed enforcement device that is installed without being fixed to the fixed unit 50.

[0082] Next, the control unit 11 judges whether to end the process of FIG. 5 (step S4). There is no particular trigger for ending the process, but it may be, for example, that the power of the electronic device 10 is turned off by operating the operation unit 19, or that the route guidance function is stopped. If the control unit 11 judges "NO" in step S4, it returns to the process of step S1 and repeats the above process. If the control unit 11 no longer receives laser light, or a predetermined time has passed since it stopped receiving it, and the control unit 11 no longer has a predetermined proximity relationship with the installation point of the fixed unit 50, the control unit 11 stops the alarm. If the control unit 11 judges "YES" in step S4, it ends the process of FIG. 5 (step S5).

[0083] <1-2-2. Location-based alerts> 7 is a flowchart showing the operation of the control unit 11 of the electronic device 10. When the operation of the electronic device 10 starts, the control unit 11 executes the process described below. The trigger for starting the operation of the electronic device 10 may be the same as in <1-1. Alarm control based on reception of laser light>.

[0084] The control unit 11 acquires position information of the current position of the vehicle 40 (electronic device 10) from the GPS receiving unit 16 (step S11). Next, the control unit 11 compares the acquired position information with the position information of the fixed unit 50 stored in the database 181 (step S12). Next, the control unit 11 determines whether the vehicle 40 and the installation point of the fixed unit 50 are in a predetermined proximity relationship based on the position information acquired in step S11 and any of the position information stored in the database 181 (step S13). The predetermined proximity relationship may be, for example, a distance between the position information of the installation point and the position information of the vehicle 40 that is a predetermined distance or less (for example, 1 km or less). The predetermined proximity relationship may be determined based on the position relationship between the vehicle 40 and the fixed unit 50, such as the presence of the installation point in the traveling direction of the vehicle or the presence of the installation point on the road on which the vehicle travels.

[0085] If the result of the determination in step S13 is "YES", the control unit 11 performs control (second alarm control) to warn the vehicle 40 of approaching the installation point of the fixed unit 50 (step S14). In this way, when the vehicle 40 approaches each of the fixed units 50 (for example, each support), the control unit 11 can warn the vehicle 40 of approaching the installation point of the fixed unit 50. The alarm in step S14 is issued when the vehicle 40 is approaching the installation point but the electronic device 10 has not received the laser light. Therefore, the electronic device 10 may not be currently enforcing the law at the installation point, or may be enforcing the law but has not been able to receive the laser light for some reason. Therefore, the control unit 11 may issue an alarm different from that in step S3 in step S14. More preferably, the control unit 11 may issue an alarm that allows the user to recognize that the vehicle 40 is an installation point of the fixed unit 50. The control unit 11 may further display an image (for example, an icon or other object) indicating the presence of the installation point of the fixed unit 50 on the map M based on the position information of the installation point of the fixed unit 50.

[0086] FIG. 8 is a diagram showing an example of a warning screen. The warning screen shown in FIG. 8 is a screen in which a window W2 is superimposed on a map M. The window W2 displays a message indicating the presence of an installation point, such as "This is a point where a speed enforcement device can be installed." In addition, the control unit 11 may output a voice saying "This is a point where a speed enforcement device can be installed" from the speaker 14. In this way, the presence of the installation point of the fixed unit 50 can be notified based on the position information of the electronic device 10, so that even if the electronic device 10 does not receive laser light from the speed enforcement device 30, the presence of the device can be notified. In addition, the electronic device 10 makes the warning when the laser light is not received different from the warning when the laser light is received, so that it is expected to have the effect of reducing the misunderstanding and dissatisfaction of the user caused by the fact that the speed enforcement device 30 is not actually present.

[0087] Next, the control unit 11 judges whether to end the process of FIG. 7 (step S15). The timing for ending the process is not particularly limited, but may be, for example, when the power of the electronic device 10 is turned off by operating the operation unit 19 or when the route guidance function is stopped. If the control unit 11 judges "NO" in step S15, the control unit 11 returns to the process of step S11 and repeats the above process. If the position information of the vehicle 40 and the position information of the installation point of the fixed unit 50 are no longer in a predetermined proximity relationship, the control unit 11 may stop the alarm. If the control unit 11 judges "YES" in step S15, the control unit 11 ends the process of FIG. 8 (step S16).

[0088] <1-2-3. Combination of alarms based on laser light reception and alarms based on location information> This operation example is based on a combination of <1-1. Alarm control based on reception of laser light> and <1-2-2. Alarm based on location information>. Fig. 9 is a flowchart showing the operation of the control unit 11 of the electronic device 10. When the operation of the electronic device 10 starts, the control unit 11 executes the process described below. The trigger for starting the operation of the electronic device 10 may be the same as <1-1. Alarm control based on reception of laser light>.

[0089] The control unit 11 acquires a signal from the light receiving unit 12 (step S1). Next, the control unit 11 executes the processes of steps S11 to S13. If the result of the determination in step S13 is "YES", the control unit 11 determines whether or not the laser light has been received (step S2). If the result of the determination in step S2 is "YES", the control unit 11 performs control (first warning control) to warn of the approach to the speed enforcement device 30 (step S3). After executing the process of step S3, the control unit 11 proceeds to the process of step S4. If the result of the determination in step S2 is "NO", the control unit 11 performs control (second warning control) to warn of the approach of the vehicle 40 to the installation point of the fixed unit 50 (step S14). In this way, when the vehicle 40 approaches each fixed unit 50 (for example, each support), the control unit 11 can warn of the approach to the installation point of the fixed unit 50. After executing the process of step S14, the control unit 11 proceeds to the process of step S4. The processes in steps S4 and S5 may be the same as those in <1-1. Alarm control based on reception of laser light>.

[0090] As described above, by issuing an alarm regarding the speed enforcement device 30 or the fixed unit 50, the electronic device 10 makes the user, such as the driver of the vehicle 40, pay attention to speed enforcement, which contributes to safe driving.

[0091] The above-mentioned warning regarding approach to the speed enforcement device 30 may be a warning indicating the reception of a speed measurement signal from the speed enforcement device, but it is preferable to be a warning indicating that a speed enforcement device is installed in a fixed part. For example, the electronic device 10 stores the position information of a post (an example of a fixed part) installed on a route such as an urban expressway to install a semi-fixed speed enforcement device. When the vehicle 40 approaches each post, the control unit 11 issues an alarm to the effect that it is approaching the location of a post for installing a semi-fixed speed camera (for example, an alarm stating ``Approaching a post where a semi-fixed speed camera can be installed!''), and then, if a speed measurement signal is received from a speed enforcement device (speed camera) before reaching the location of the post that issued the alarm, it may be configured to simply issue an alarm stating that a speed measurement signal has been received, saying ``Enforcement laser received'', but it is also preferable to issue an alarm that indicates that a speed enforcement device is fixed to the fixed unit, such as ``There is a speed camera on a post where a semi-fixed speed camera can be installed! Watch your speed!'', or an alarm that includes both an indication that a speed enforcement device is fixed to the fixed unit 50 and an indication that a speed measurement signal has been received, such as ``There is a speed camera on a post where a semi-fixed speed camera can be installed! Laser received! Watch your speed!''

[0092] Thus, in the first embodiment described above, the electronic device 10 may determine that a speed enforcement device 30 is installed on the fixed part 50 by detecting the reception of a speed measurement signal such as laser light. For example, if the electronic device 10 detects laser light from a speed enforcement device 30 that is a laser-type speed camera after issuing a warning of approach to the post position (the position of the fixed part 50), it may further issue a warning indicating that a semi-fixed speed camera is present on the post.

[0093] [2. Second embodiment] The electronic device 10 may determine the presence of the speed enforcement device 30 by a method using an imaged image instead of or in addition to determining the presence of the speed enforcement device 30 by receiving laser light. The electronic device 10 of this embodiment communicates with an imaging device 70 (see FIG. 4) via the communication unit 17. The imaging device 70 captures an image of the area in front of the vehicle 40. The imaging device 70 is, for example, a drive recorder, but may also be a device having an imaging function such as a smartphone. There is no restriction on the algorithm for analyzing the captured image, and examples of the algorithm include a method using deep learning and a method using machine learning (such as a pattern matching method). The control unit 11 analyzes the image acquired from the imaging device 70 and performs a process of recognizing a predetermined image indicating the installation location of the fixed unit 50 or a speed enforcement location. The predetermined image indicating the installation location of the fixed unit 50 may be an image of the exterior of the fixed unit 50. The predetermined image indicating the speed enforcement location may be an image of the exterior of the speed enforcement device 30, or may be a signboard (in this embodiment, the signboard 60 shown in FIG. 2) that may be installed at the installation location. On routes where speed enforcement is currently taking place, a signboard 60 warning of upcoming enforcement may be installed about 1-2 km before the route, and this signboard can be used as a landmark for the speed enforcement spot. In this way, even if the fixed unit 50 or the speed enforcement device 30 has just been installed and their position information has not yet been registered in the database 181, the control unit 11 can issue a warning.

[0094] 11 is a flowchart showing the operation of the control unit 11 of the electronic device 10 in this case. The control unit 11 acquires a captured image from the imaging device 70 via the communication unit 17 (step S21). Next, the control unit 11 analyzes the captured image (step S22). The control unit 11 analyzes the image acquired from the imaging device 70 and performs processing to recognize a predetermined image indicating an installation location of the fixed unit 50 or a speed enforcement location.

[0095] Next, the control unit 11 judges whether or not there is a location where the fixed unit 50 is installed or a speed control point based on the result of image recognition (step S23). If the judgment in step S23 is "YES", the control unit 11 judges whether or not there is a speed control point (step S24). If the speed enforcement device 30 or the signboard 60 is recognized, the control unit 11 performs control (first alarm control) to warn of approaching a speed enforcement point where speed enforcement is currently being carried out (step S25). If the judgment in step S24 is "NO", the control unit 11 performs control (second alarm control) to issue an alarm in the case where the fixed unit 50 is installed (step S26). The alarm in step S25 may be the same as in step S3, and the alarm in step S26 may be the same as in step S14.

[0096] Next, the control unit 11 judges whether to end the process of Fig. 10 (step S27). If the result of the judgment in step S27 is "NO", the control unit 11 returns to the process of step S21 and repeats the above process. If the result of the judgment in step S27 is "YES", the control unit 11 ends the process of Fig. 10 (step S28).

[0097] According to this embodiment, even if the electronic device 10 cannot receive the laser light for some reason, it is possible to issue an alarm, and the possibility that the electronic device 10 will mistake other light for a laser light and issue a false alarm can be reduced. In this embodiment, the electronic device 10. Also, the determination that the speed enforcement device 30 is installed on the fixed part 50 is made when it is recognized that the speed enforcement device is reflected in the image captured by the imaging device 70. In particular, it is preferable to determine the position of the image of the imaging device 70 corresponding to the position of the fixed part 50, and to perform this determination when it is recognized that the speed enforcement device is reflected in the vicinity of the specified position. For example, when the control unit 11 detects that the speed enforcement device 30, which is a semi-fixed speed enforcement device, is installed on the post by the imaging device 70 while approaching the post position, which is the position of the fixed part 50, it is preferable to issue a warning indicating that the semi-fixed speed enforcement device is present on the post.

[0098] In this embodiment, since there is a possibility that the user will find the alarm annoying if it is issued at too early a stage, the control unit 11 may change the content of the alarm by gradually increasing the tempo with a predetermined time lag (for example, a time lag of about 500 m), and may end the alarm several seconds after the speed enforcement device is captured on screen.

[0099] [3. Third embodiment] In this embodiment, the electronic device 10 performs control (fourth alarm control) to issue an alarm regarding the speed difference from a reference speed while traveling on a road with a specific attribute. FIG. 11 is a diagram for explaining an outline of the system of this embodiment. As shown in FIG. 11, there are various types of roads. In particular, on a road called a zone 30 shown as an area Ar1 in FIG. 11, there is a possibility that the opportunities for speed enforcement will increase, and it is particularly important to observe the speed limit of the vehicle 40. Therefore, when the vehicle 40 (i.e., the electronic device 10) is in the zone 30, the control unit 11 of the electronic device 10 also notifies (in other words, informs the user) of the speed overage (i.e., the speed difference between the speed of the vehicle 100 and 30 km / h).

[0100] FIG. 12 is a flowchart showing the operation of this embodiment. The control unit 11 acquires location information (step S31). Next, the control unit 11 judges whether the location information indicates inside the zone 30 (step S32). If the judgment in step S32 is "YES", the control unit 11 performs control to issue an alarm regarding the speed difference (fourth alarm control) (step S33). The control unit 11 issues a message by voice, for example, "This is the nearby zone 30. You are currently going 10 km / h over. Please reduce your speed." The control unit 11 may notify the speed over in increments of 1 km / h, for example, or may notify in increments of 5 km / h to call attention to the speed. It is preferable that the selection of whether to notify the speed over and the above number of km / h at which to notify can be freely set by the user or other methods. On the other hand, if the result of the determination in step S32 is "NO," that is, if the current location is in Ar1 outside the zone 30, or is not close to Ar1 within a predetermined distance range, the control unit 11 turns off the function of issuing an alarm regarding the speed difference. In this way, the possibility that the speed difference will be frequently notified is reduced.

[0101] In the first place, in the past, there was a kind of unfounded common sense that no enforcement would be conducted if the speed was less than 15 km / h, and the present embodiment was conceived by the inventor as an educational activity that shows that common sense is no longer valid in Zone 30, and also as an appeal to users, and Zone 30 is more suitable in consideration of the actual driving conditions. Note that if the road attribute is a road where the reference speed such as the speed limit is known, the configuration may be such that the speed difference with roads of other attributes (green belts) is notified. However, if it is to be applied to roads other than Zone 30, it may be turned off until the user explicitly turns on the function.

[0102] [4. Fourth embodiment] The speed enforcement device 30 described in the first and second embodiments is, for example, a laser-type speed camera capable of monitoring up to two lanes simultaneously, and can be operated in such a way that fixed parts 50 (e.g., posts) are installed at multiple points on the expressway where speed control is required, and the fixed parts 50 to which the laser-type speed enforcement device 30 body is attached are changed periodically (every month, for example) in consideration of accident occurrence status, etc. Another issue with conventional speed enforcement devices is that they are expensive and therefore difficult to use on urban expressways with many curves and places where speed control is required. In light of this issue, the following configuration may be adopted.

[0103] (1) The control unit 11 may issue an alarm including a notification that a fixed unit 50 is present at or ahead of a curve. This alarm includes a notification that the vehicle 40 is about to travel or is currently travelling through a curve, and a notification that a fixed unit 50 is present at the end of this curve. The control unit 11 may issue an alarm by outputting a message saying, "There is a semi-fixed speed camera post ahead of the right curve." This alarm may be issued not only by semi-fixed speed enforcement devices 30, but also by various types of speed enforcement devices (e.g., fixed, mobile, etc.). In this way, the user can quickly identify the installation point or enforcement point even while driving on a route with poor visibility.

[0104] (2) The control unit 11 may issue an alarm indicating that the vehicle is approaching the installation point of the fixed unit 50, and may set the approach distance for issuing an alarm to the installation point of the fixed unit 50 to a distance longer than the reach of the laser light of a laser-type speed enforcement device. In this case, when the control unit 11 detects laser light after issuing an alarm indicating that the vehicle is approaching the installation point of the fixed unit 50, it may further issue an alarm indicating that a speed enforcement device 30 fixed to the fixed unit 50 is present. The distance for issuing an approach warning when the vehicle approaches the fixed unit 50 within a predetermined distance may be set to a distance longer than the reach of the speed measurement signal of the speed enforcement device 30 fixed to the fixed unit 50. When the speed enforcement device 30 measures the speed of the vehicle using laser light as a speed measurement signal, it may be set to a distance longer than the reach of the laser light. For example, if the reach of the laser light is 200 m, the approach warning to the fixed unit 50 may be set to a distance longer than 200 m, such as 500 m.

[0105] (3) When the control unit 11 determines that the speed enforcement device 30 is installed on the fixed unit 50 using the imaging device 70 while approaching the installation point of the fixed unit 50, it may issue an alarm to the effect that there is a speed enforcement device 30 fixed to the fixed unit 50. In this case, if the control unit 11 detects that the speed enforcement device 30 is installed on the fixed unit 50 using the imaging device 70 but does not receive a laser, it may notify the user that there is a high possibility that the speed enforcement device 30 was not operating.

[0106] (4) If the control unit 11 detects from an image captured in front of the vehicle 40 by the imaging device 70 that a speed enforcement device is installed on the fixed unit 50 but does not receive a speed measurement signal, it may issue a notification indicating that it is highly likely that the speed enforcement device was not in operation. For example, if the control unit 11 recognizes from an image captured by the imaging device 70 that a laser-type semi-fixed speed camera is installed on a pillar but does not receive a laser, it may issue a notification indicating that it is highly likely that the speed camera was not in operation, such as, for example, "There was a laser-type semi-fixed speed camera on the pillar, but the laser was not detected. It appears to be out of operation."

[0107] [5. Fifth Embodiment] The electronic device according to an embodiment of the present invention may perform a process of posting to another device that no speed enforcement device was installed in the fixed unit 50. Assuming the configuration of the fifth embodiment described above, the other device may be the server device 200, but may also be the electronic device 10A mounted on another vehicle. The control unit 11 may issue an alarm indicating that the fixed unit 50 in which the speed enforcement device 30 is installed is approaching, for example, for the fixed unit 50 in which the speed enforcement device 30 is installed recently posted, the control unit 11 may issue an alarm (approaching speed camera alarm). Based on the installation period of each location where the speed enforcement device 30 is installed in the fixed unit 50, another device (e.g., a server, etc.) may be provided that estimates the next movement time and movement location and delivers information to the electronic device 10. For example, based on the installation period of each location where the speed enforcement device 30 is installed in the fixed unit 50, the next movement time (and movement location) may be estimated and delivered from the server device 200 to this device. In this way, other devices can be made aware that no speed control device is installed on the fixed portion 50.

[0108] FIG. 13 is a block diagram showing the configuration of a system 2 of this embodiment. As shown in FIG. 13, the system 2 has a plurality of electronic devices 10A and a server device 200. The electronic device 10A is different from each of the above-mentioned embodiments in that it can communicate with the server device 200 and controls in cooperation with the server device 200. The plurality of electronic devices 10A are used by different users. The plurality of electronic devices 10A communicate wirelessly with the server device 200 via a public communication line, a dedicated line, or other communication line. The plurality of electronic devices 10A have a function of transmitting location information of the installation point of the fixed unit 50 to the server device 200, receiving location information of the installation point of the fixed unit 50 distributed from the server device 200, and registering the information in the database 181.

[0109] The server device 200 is managed and operated by a specified business operator. The server device 200 has a control unit 210, a communication unit 220, and a database 230. The control unit 210 is, for example, a computer including an arithmetic processing circuit and a memory, and controls each unit of the server device 200. The communication unit 220 communicates with each of the multiple electronic devices 10A. The database 230 accumulates data collected from the multiple electronic devices 10A and data to be distributed to the multiple electronic devices 10A. The database 230 is realized by a hard disk or other storage device, but may be realized by using a cloud computing environment or other external storage means.

[0110] FIG. 14 is a sequence diagram showing a flow of processing of the system 2 when transmitting data from the electronic device 10A to the server device 200. When the control unit 11 of the electronic device 10A determines that the location is an installation location of the fixed unit 50 (step S101), it transmits position information corresponding to the installation location to the server device 200 (i.e., performs posting processing) (step S102). In the server device 200, the control unit 210 registers the received position information (posted position information) in the database 230 (step S103). The method of determining the installation location of the fixed unit 50 in step S101 can adopt the method described in each of the above-mentioned embodiments. The position information corresponding to the installation location of the fixed unit 50 may be the position information of the vehicle 40 when the control unit 11 determines that the location is an installation location, may be the position information of the installation location estimated therefrom, or may be the position information input by the user. The electronic device 10A may transmit the position information of the installation location that is not registered in the database 181. In this way, unnecessary data does not need to be transmitted, and the server device 200 does not need to store unnecessary data.

[0111] FIG. 15 is a sequence diagram showing a process flow of the system 2 when the electronic device 10A receives data from the server device 200. The control unit 210 of the server device 200 generates distribution information (step S111). The distribution information may include location information of an installation point that is not registered in the electronic device 10A. The control unit 210 transmits the generated distribution information to the electronic device 10A via the communication unit 220 (step S112). The control unit 11 of the electronic device 10A acquires the location information of the installation point from the received distribution information and registers it in the database 181 (step S113). The control unit 11 thereafter uses this location information for warning control of the installation point. In this way, even if the installation points are increased or changed, a warning can be issued to the effect that the electronic device 10A is approaching the installation point.

[0112] In steps S101 and S102, the control unit 11 may post that no speed enforcement device 30 has been installed in the fixed unit 50. The control unit 11 may also issue an alarm for any recent posts about speed enforcement devices 30 in the fixed unit 50. For example, this alarm may be issued when there is a post about no speed enforcement devices 30 for a predetermined period of time going back from the current date and time. The server device 200 may estimate the next movement time (and / or movement location) based on the installation period for each location where a speed enforcement device 30 is installed in the fixed unit 50, and distribute the information to the electronic device 10A.

[0113] When the number of semi-fixed speed cameras that have already issued warnings reaches the number of semi-fixed speed cameras owned by the prefectural police, it is advisable to suppress any of the above-mentioned warnings at the installation locations of the fixed units 50 on that route. Suppressing the warning may mean, for example, not issuing a warning.

[0114] [6. Modifications] The present disclosure is not limited to the above-described embodiments, and can be modified as appropriate without departing from the spirit and scope of the present disclosure. (Variation 1) The control unit 11 of the electronic device 10 may suppress control to issue an alarm when the fixed unit 50 is recognized from an image captured by the imaging device 70 of the area ahead of the vehicle 40 and the laser light is not received by the light receiving unit 12. In this case, suppressing control to issue an alarm can be achieved by not issuing an alarm, or by lowering the volume, the display, or the alarm level, as compared to when an alarm is issued but not suppressed. In this way, the fixed unit 50 is present but speed enforcement is not being carried out, so that unnecessary information is not provided to the user.

[0115] (Variation 2) In urban areas, when the volume of the electronic device 10 is turned down and the electronic device 10 moves onto a highway, the alarm sound may be difficult to hear due to road noise caused by high-speed driving because the volume is low. Therefore, when the control unit 11 of the electronic device 10 detects that the electronic device 10 is driving on a highway, the control unit 11 may set the volume of the alarm (alarm volume) to a preset volume. This volume may be set to a volume that does not interfere with the user's recognition of the voice even while driving on the highway. In this way, it is possible to increase the recognition of the alarm sound on the highway. For example, the control unit 11 may set the volume by adding a predetermined value to the currently set volume so that the volume is louder while driving on a highway than while driving on a road other than the highway, such as a general road. The determination of whether or not the electronic device 10 is driving on a highway may be based on location information and road information, or various known techniques may be adopted.

[0116] If it is difficult to detect that the vehicle is traveling on an expressway, the control unit 11 may set the volume of the warning (warning volume) to a preset volume at a certain speed or higher. With this method, the warning volume is changed when the speed increases regardless of whether the vehicle is on a general road or an expressway, thereby increasing the awareness of the warning sound and reducing the number of times the warning sound is missed.

[0117] (Variation 3) Although the case where the semi-fixed speed enforcement device is compatible with the laser system has been described, the present invention can also be applied to cases where an alarm is issued for approaching a location where a speed enforcement device that emits a radar-based or other type of speed measurement signal (measurement wave) is installed. For example, the electronic device 10 may determine that the speed enforcement device 30 is installed in the fixed part 50 by detecting the reception of radio waves or other speed measurement signals (measurement waves) for measuring the speed of the vehicle.

[0118] (Variation 4) Some of the configurations and operations described in the above-mentioned embodiments may be omitted or modified. For example, the fixed unit 50 does not need to have either the power supply unit 51 or the line unit 52, and may be any device that is used for the operation or installation of the speed enforcement device 30. For example, when the invention is specified by the function related to <1-2-2. Alarm based on location information>, the fixed unit 50 does not need to have a receiver for speed measurement signals.

[0119] The scope of the present invention is not limited to the configurations expressly described in the specification, but includes combinations of various aspects of the present invention disclosed herein. The configurations of the present invention for which a patent is sought are specified in the appended claims, but it is the intention of the present inventors to include in the claims any configurations disclosed in this specification that are not currently specified in the claims.

The configurations of the present invention that are to be patented are specified in the attached claims, but it is our intention to include configurations disclosed in this specification in the claims in the future, even if they are not currently specified in the claims.

[0121] The present invention is not limited to the configuration described in the above-mentioned embodiment. The components of each of the above-mentioned embodiments and modifications may be arbitrarily selected and combined. Any components of each of the embodiments and modifications may be arbitrarily combined with any components described in the means for solving the invention or any components that embody any components described in the means for solving the invention.
