Summary of the Invention

Problems to be Solved by the Invention

[0004] One object of the present invention is to provide a technology related to vehicle speed control.

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

Means for Solving the Problems

[0006] There is provided a system having a control unit that performs warning control for warning of approaching a location where a fixing portion to which a speed regulating device is fixed is provided in a vehicle.

[0007] In this way, it is possible to make the user aware of approaching a location where the speed regulating device is installed and enforcement may be carried out.

[0008] In particular, it is preferable that the speed control device performs warning control to warn of approaching the "installation location of the detachable fixing part". The warning content should not be a warning indicating approach to the speed control device, but rather a warning indicating approach to the position where there is a fixing part where the speed control device can be installed. For example, instead of "There is a speed camera 500 m ahead. Caution: Speed Limit!", it is better to warn like "There is a pole where a speed camera can be installed 500 m ahead. Caution: Speed Limit!" or "There is a pole for a semi-fixed speed camera 500 m ahead. Caution: Speed Limit!". It may also be "There is a position where a speed camera can be installed 500 m ahead. Caution: Speed Limit!", but in particular, it is better to include something indicating a specific structure, such as "There is a pole where a speed camera can be installed 500 m ahead. Caution: Speed Limit!", and especially better to include something indicating at least a part of the structure of the fixing part. In this way, the user can pay attention to this structure, easily check whether a speed control device is actually installed on the fixing part, etc. The warning content may be stored in the storage means of the system and output by voice, character string, image, etc. Conventional systems stored the position of the speed control device itself and issued a warning indicating approach to that speed control device. However, in the case of a semi-fixed speed camera where the speed control device has a detachable fixing part that is pre-installed on the road shoulder, etc., and the configuration allows for changing at any time whether to install the speed control device on that fixing part, the inventors found that it is inappropriate to issue a warning indicating approach to the speed control device as the warning content. The installation position of the fixing part should be investigated and grasped in advance, and the position information of the fixing part should be stored in the storage means in association with information indicating that it is the fixing part. Based on this position information of the fixing part and the information indicating that it is the fixing part, a configuration may be adopted to determine whether to issue this warning. Note that the speed control device only needs to include at least a vehicle speed measurement unit, and it is better to further include an imaging unit that images vehicles exceeding the speed limit.

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

[0010] By doing so, it is possible to let the user know the approach to a location where a speed enforcement device may be installed and enforcement may be carried out.

[0011] In particular, instead of the installation location of a speed enforcement device as in the prior art, based on the position information of the "installation location of the detachable fixing part" of the speed enforcement device and the position information of the vehicle, it is advisable to perform alarm control with the content of approaching the installation location. For example, store the positions of the pillars installed on a route such as an urban expressway for installing semi-fixed orbits, and when approaching each pillar, perform control to notify an alarm indicating that it is approaching the pillar position for installing the semi-fixed orbit.

[0012] (3) The fixing part may preferably have at least one of a power supply part for supplying power to the speed enforcement device and a line part for the speed enforcement device to communicate.

[0013] By doing so, based on the installation location of the fixing part having a power supply part or a line part for operating the speed enforcement device, it is possible to let the user know the location where the speed enforcement device may be installed and enforcement may be carried out.

[0014] (4) When the control part determines that the speed enforcement device is installed on the fixing part, it is advisable to perform first alarm control.

[0015] By doing so, when the speed enforcement device is actually installed, it is possible to let the user know that fact.

[0016] In particular, based on the position information of the installation location of the fixed part where the speed enforcement device can be attached / detached, rather than the installation location of the speed enforcement device, and the position information of the vehicle, after issuing a warning indicating approach to the installation location of the fixed part, if it is determined that the speed enforcement device is installed on the fixed part before reaching the installation location of the fixed part, it is advisable to further issue a warning indicating approach to the speed enforcement device. This further warning indicating approach to the speed enforcement device may be a warning indicating reception of a speed measurement signal from the speed enforcement device, but it is particularly advisable to be a warning indicating that the speed enforcement device is installed on the fixed part. For example, store the positions of the columns installed on routes such as urban expressways for installing a semi-fixed orbis as a speed enforcement device, and when approaching each column, issue a warning indicating approach to the column position for installing the semi-fixed orbis (for example, a warning like "Approaching the column where semi-fixed orbis can be installed!"), and if a speed measurement signal is received before reaching the position of the warned column, it may be possible to simply issue a warning indicating reception of the speed measurement signal such as "Received the enforcement laser", but it may be better to make the content indicate that there is a speed enforcement device on the fixed part like "There is an orbis on the column where semi-fixed orbis can be installed! Pay attention to speed!", or issue a warning including the content indicating that there is a speed enforcement device on the fixed part and the content indicating reception of the speed measurement signal like "There is an orbis on the column where semi-fixed orbis can be installed! Laser received! Pay attention to speed!". Note that the speed measurement signal is a signal for speed measurement emitted by the speed enforcement device and may also be referred to as a measurement wave for speed enforcement.

[0017] The determination that a speed enforcement device is installed at the fixed part may be made by detecting that there has been reception of radio waves, light, etc. for measuring the speed of the vehicle. For example, when a laser of a laser type orbis is detected after a proximity warning to the support column position, a warning indicating that a semi-fixed orbis exists on the support column may be further given. Also, the determination that a speed enforcement device is installed at the fixed part may be made when it is recognized that the speed enforcement device appears in the video imaged by the camera. In particular, the position of the camera video corresponding to the position of the fixed part may be specified, and it may be made when it is recognized that the speed enforcement device appears in the vicinity of the specified position. For example, when it is detected by the camera that a semi-fixed orbis is installed on the support column while approaching the support column position, a warning indicating that a semi-fixed orbis exists on the support column may be given.

[0018] The distance at which a proximity warning is given when approaching the fixed part to a predetermined distance may be set to a distance longer than the reach distance of the speed measurement signal of the speed enforcement device fixed to the fixed part. For example, when the speed enforcement device measures the speed of the vehicle by laser, it may be set to a distance longer than the reach distance of the laser. For example, if the reach distance of the laser is 200 m, the proximity warning to the fixed part may be set to a distance longer than 200 m, such as 500 m.

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

[0020] By doing so, since a warning is given when the measurement wave speed measurement signal from the speed enforcement device is received, the user can more accurately recognize the presence of the speed enforcement device.

[0021] (6) When the control unit recognizes the speed enforcement device or a predetermined sign installed at the speed enforcement location from the image obtained by imaging the front of the vehicle, the control unit may perform the first warning control.

[0022] By doing so, even if the measurement wave velocity measurement signal from the speed enforcement device is not received, the user can be made aware of the information about the location where the speed enforcement device is installed.

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

[0024] In this way, the information about the location where a speed enforcement device may be installed can be notified to the user based on the result of actually driving in the vicinity.

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

[0026] By doing so, although the enforcement device is not installed at present, the user can be made aware of the information about the location where enforcement may be carried out.

[0027] (9) When the fixing unit is recognized from the image captured of the front of the vehicle, the control unit performs the second warning control.

[0028] In this way, based on the image captured from the vehicle, the user can be made aware of the information about the location where enforcement may be carried out.

[0029] (10) When the speed enforcement device or a predetermined sign installed at the speed enforcement location is not recognized from the image captured of the front of the vehicle, the control unit does not perform the second warning control It is advisable to do so.

[0030] In this way, when a speed enforcement device or a predetermined sign is installed at the speed enforcement location, but these are included in the image captured from the vehicle, a warning is issued, so that when the speed enforcement device is actually installed, the user can be made aware of that fact.

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

[0032] In this way, it is possible to issue a warning in response to a change in the location of the speed enforcement location.

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

[0034] In this way, it is possible to issue a warning in response to a change in the location of the speed enforcement location.

[0035] (13) The control unit registers in the database information specifying the time point when the presence of the fixing unit is confirmed in the position information of the installation location of the fixing unit, and when the position information of the vehicle is in a predetermined proximity relationship with the position information of the installation location of the fixing unit within a predetermined period retroactively from the current time point, the control unit may perform control to issue a second warning.

[0036] In this way, it is possible to allow the user to grasp with higher accuracy that the vehicle is approaching the installation location of the fixing unit.

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

[0038] By doing so, other devices can be made aware that the speed regulating device is not installed on the fixed part. It is preferable to have a function of posting to other devices that the speed regulating device is not installed on the fixed part. For example, it is preferable to have a function of posting that there is no orbis installed on the support column. For the fixed parts where it has been recently posted that the speed regulating device is installed on the fixed part, an approach warning may be given. For example, an orbis approach warning may be given for those where it has been recently posted that there is an orbis installed on the support column. Based on the installation period for each location where the speed regulating device is installed on the fixed part, it is preferable to provide another device (such as a server, etc.) that estimates the next movement time and movement location and distributes them to this device. For example, based on the installation period for each location where there is an orbis installed on the support column, it is preferable to estimate the next movement time (and movement location) and distribute it from a server, etc. to this device.

[0039] (15) When the installation location of the fixed part or the installation location of the speed regulating device exists at or ahead of a curve, the control unit may perform control to give an alarm of approaching the installation location along with notification to that effect.

[0040] By doing so, even on a route with poor visibility at a curve, the user can be made aware of the information on the installation location of the fixed part.

[0041] (16) The control unit may perform a third alarm control that issues an alarm including notification of the type of the speed regulating device.

[0042] In this way, the user can be made aware of the type of the speed regulating device.

[0043] (17) It has a receiving unit that receives the measurement wave speed measurement signal emitted by the speed regulating device, and when the fixed part is recognized from the image captured in front of the vehicle by the control unit and the measurement wave speed measurement signal is not received by the receiving unit, the control unit may suppress the control of issuing an alarm.

[0044] By doing so, although there is a fixed part, since speed enforcement is not being carried out, the provision of unnecessary information to the user can be suppressed.

[0045] (18) It is preferable to have a receiving unit that receives the speed measurement signal emitted by the speed enforcement device, and when the control unit recognizes the fixed part from an image obtained by imaging the front of the vehicle, if the receiving unit does not receive the speed measurement signal, it is preferable to give a notification indicating that it is highly likely that the speed enforcement device was not operating.

[0046] By doing so, it is possible to let the user know that, although it is an installation location, it is highly likely that the speed enforcement device was not operating. For example, when it is detected from an image obtained by imaging the front of the vehicle with a camera that a speed enforcement device is installed on a fixed part, but no speed measurement signal is received, it is preferable to give a notification indicating that it is highly likely that the speed enforcement device was not operating. For example, when it is recognized from the video from the camera that a laser-type semi-fixed orbis is installed on a pole, but no laser is received, it is preferable to give a notification indicating that it is highly likely that the speed enforcement device (orbis) was not operating, such as "There was a laser-type semi-fixed orbis on the pole, but no laser was detected. It seems to be stopped."

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

[0048] By doing so, when the attribute of the road is a predetermined attribute, it is possible to give a notification to encourage the user to drive more safely. It can be done.

[0049] (20) It is preferable to adopt a system in which the attribute of the road is Zone 30.

[0050] In this way, even in a place where it is likely to be recognized that the zone 30 will not be regulated, notification can be made.

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

[0052] By doing so, it is possible to let the user know the locations where a speed regulating device is installed and regulation may be carried out.

[0053] The inventions described in (1) to (20) above can be arbitrarily combined. For example, it is preferable to adopt a configuration in which at least a part of the configuration of at least one of the inventions described in (2) and subsequent items is added to all or a part of the configuration of the invention described in (1). In particular, it is preferable to adopt an invention in which at least a part of the configuration of at least one of the inventions described in (2) and subsequent items is added to the invention described in (1). Also, any configuration may be extracted from the inventions described in (1) to (20), and the extracted configurations 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 order in the descriptions with an order is 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 them.

Mode for Carrying Out the Invention

[0057] Hereinafter, the embodiments will be described in detail with reference to the drawings. The following embodiments 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 the same functions are denoted by the same reference numerals or similar reference numerals (reference numerals with A, B, etc. appended after the numbers), and the repeated description may be omitted. In addition, in each of the drawings referred to in the following description, the scale may be different from the actual one in order to make each member, each region, etc. recognizable. Hereinafter, the case where the system of the present disclosure is applied to a system mounted on a vehicle and detecting a speed enforcement device will be described. The vehicle is preferably an automobile, but is not limited to a four-wheel automobile, and may be, for example, a two-wheel vehicle such as a motorcycle or a large transport vehicle having four or more wheels.

[0058] [1. First Embodiment] <1-1. Configuration> FIG. 1 is a diagram showing the configuration of the system according to the first embodiment. The 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 the laser light emitted by the 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 also be referred to as a measurement wave for speed enforcement. The appearance of the speed enforcement device shown in FIG. 1 is an example, and a different appearance may be used. The laser light is light of a specific wavelength and is a pulsed laser having a predetermined pulse width. The specific wavelength belongs to, for example, the infrared light region and is, for example, any one 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. "Approximately" may be within a predetermined range that can be regarded as the same as the reference value or substantially the same as that 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 the vehicle 40. The electronic device 10 is installed on the dashboard 41, for example, using double-sided tape. An opening is provided in the front surface 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 the vehicle is enforced. The speed enforcement point is determined in consideration of situations such as the driving conditions of the vehicle (for example, the vehicle is likely to gain speed) and the occurrence situation of traffic accidents (for example, a location with a high number of accidents). As an example of the speed enforcement point, among the routes (roads) on which the vehicle travels, there is a curve or a point ahead of the curve. The speed enforcement device 30 is also referred to as a semi-fixed laser orbis and is installed on a fixing portion 50 installed on the road shoulder of a route such as an urban expressway or other expressway. The fixing portion 50 is, for example, a column on which the speed enforcement device 30 is installed. However, the form of the fixing portion 50 as a structure is not limited to this.

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

[0062] As shown in Fig. 2, when the speed enforcement device 30 is fixed to the fixing part 50, the installation location of the fixing part 50 becomes the speed enforcement location. As shown in Fig. 3, when the speed enforcement device 30 is not fixed to the fixing part 50, the installation location of the fixing part 50 is not the speed enforcement location at that time. Thus, the fixing part 50 is installed at a location where vehicle speed enforcement may be carried out, or a candidate location for speed enforcement. The sign 60 shown in Fig. 2 is a sign that may be installed at the speed enforcement location, and is installed, for example, a predetermined distance (e.g., 1 - 2 km) ahead in the traveling direction (forward direction) of the road compared to the installation location of the speed enforcement device 30.

[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 by, for example, the laser scanning method. Specifically, the speed measurement unit 31 emits laser light Lout, and when this reaches the vehicle 40 and is reflected, it receives the reflected light Lref. The speed measurement unit 31 measures the distance to the vehicle 40 based on the time required from when the laser light Lout is emitted until the reflected light Lref is received. 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 fan-shaped range T with a central angle of angle θ, for example, while changing the direction counterclockwise. The emission direction of the laser light Lout is, for example, substantially horizontal. The speed measurement unit 31 emits the laser light to a mirror that rotates 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] When the speed measured by the speed measurement unit 31 is equal to or higher than the threshold value, the imaging unit 32 images the target vehicle. The imaging unit 32 is used to image a vehicle that violates the speed limit. The strobe 33 emits light when imaged by the imaging unit 32. The imaging unit 32 may perform imaging based on light in the infrared light region so that imaging can be performed even at night. In this case, the strobe 33 may emit light having energy in the infrared light 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 the electrical configuration of the electronic device 10. Note that the imaging device 70 has a configuration related to the second embodiment and is omitted in this embodiment. The control unit 11 controls each part of the electronic device 10. The control unit 11 is a computer including, for example, an arithmetic processing circuit and a memory. The arithmetic processing circuit includes, for example, a CPU (Central Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or other arithmetic processing circuits. The memory includes, for example, a RAM (Random Access Memory) or other volatile memories. The arithmetic processing circuit performs various controls by temporarily reading data from 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 optical members such as a visible light cut filter and 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 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 images. The display unit 13 is, for example, a 3.2-inch color TFT liquid crystal display. The display unit 13 may also be an organic EL display or a display device of another type. The speaker 14 outputs sound. The microwave receiving unit 15 includes an antenna and a receiving circuit and receives microwaves. The microwave receiving unit 15 also has a function of receiving radio waves (for example, microwaves) from a speed enforcement device corresponding to the radar method. The GPS (Global Positioning System) receiving unit 16 includes an antenna and a receiving circuit and receives signals from GPS satellites. The GPS receiving unit 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 preferably regarded 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 of, for example, Wi-Fi (registered trademark), Bluetooth (registered trademark), or another method.

[0068] The storage unit 18 stores data. The storage unit 18 stores, for example, a program for the control unit 11 to perform various controls. The control unit 11 reads the program from the storage unit 18 into the memory and executes it. Further, the storage unit 18 stores map data indicating a map, data indicating the types and locations of various facilities, data for notifying the presence of warning objects, data for realizing a route guidance function, and the like. Warning objects include, for example, drowsy driving accident locations, speed enforcement devices (radar type, loop coil type, H system, LH system, photoelectric tube type, mobile type, etc.), speed limit switching points, enforcement areas, checkpoint areas, no-parking monitoring areas, N system, traffic monitoring system, intersection monitoring points, signal violation suppression system, police stations, accident-prone areas, vehicle-targeted crime-prone areas, sharp / continuous curves (highway), branch / merge points (highway), ETC lane pre-guidance (highway), service areas (highway), parking areas (highway), highway oasis (highway), smart interchange (highway), gas stations inside PA / SA (highway), tunnels (highway), highway radio reception areas (highway), prefecture boundary notifications, road stations, viewpoint parking, etc. The storage unit 18 stores the type information of these warning objects, the position information indicating their positions, the data of the image (for example, a schematic diagram or a photograph) to be displayed on the display unit 13, and the audio data in association with each other.

[0069] The storage unit 18 has a database 181 that stores the position information of the installation location of the fixing unit 50. The position information stored in the database 181 includes not only the information that has already been stored at the product shipment stage of the electronic device 10, but also, as will be described later, the position information distributed by a server device of a predetermined operator may be stored.

[0070] Note that 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 receives the operations of 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 the 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 operations.

[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 is a sensor that detects the geomagnetism and detects in which direction the north direction is with respect to the traveling direction. The acceleration sensor is a sensor that detects the acceleration of the vehicle in the front-rear, left-right, and up-down directions. The illuminance sensor is a sensor that detects the illuminance indicating the brightness inside the vehicle cabin.

[0073] The mounting unit 21 is a mounting unit on which an external storage medium is mounted. The external storage medium is, for example, a memory card. In this case, the mounting unit 21 is a memory card slot. The data stored in the storage unit 18 may be imported via the external storage medium. As this data, there is update information of information (position information such as longitude and latitude, type information, etc.) of a new warning target.

[0074] The power supply unit 22 supplies the power supplied from the power source to each part 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 the vehicle's cigarette socket via the cigarette plug cord to receive power supply. The power switch is a switch for turning on or off the power of the electronic device 10.

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

[0076] The cable terminal portion 24 is a terminal to which an external connection cable is connected. For example, the connection cable is a cable for connecting the electronic device 10 to an OBD-II connector mounted on a vehicle. The OBD-II connector, also referred to as a fault diagnosis connector, is connected to the vehicle's ECU and outputs various vehicle information.

[0077] In addition to the above, the electronic device 10 may have functions provided in well-known laser detectors and radar detectors. For example, there are many speed enforcement 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. The electronic device 10 may have a function of receiving laser light from such a speed enforcement device other than the semi-fixed type 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 processes described below. The timing of the start of the operation of the electronic device 10 is not particularly limited, but for example, it may be triggered by the power of the electronic device 10 being turned on, or the start of the execution of the route guidance function in the navigation function.

[0079] <1-2-1. Alarm Based on Reception of Laser Light> The control unit 11 acquires a signal from the light receiving unit 12 (step S1). Next, the control unit 11 determines whether laser light has been received based on the acquired signal (step S2). The control unit 11 may determine whether laser light has been received based on the pulse width, pulse interval, number of pulses, wavelength, waveform, and other characteristics. If it is determined "YES" in step S2, the control unit 11 performs control to alert the approach to the speed enforcement device 30 (first alert control) (step S3). The first alert control may be performed by a method that allows the user to recognize the presence of the speed enforcement device 30. For example, at least any one of voice output, display on the display unit 13 of the alert screen, and light emission control of the light emitting unit 23 is used. In this embodiment, the alert is to notify the user of the presence of the speed enforcement location or the installation location of the fixing unit 50.

[0080] FIG. 6 is a diagram showing an example of an alert screen. The alert screen shown in FIG. 6 is a screen in which a window W1 is superimposed on a map screen M1. The control unit 11 issues an alert by displaying the window W1 superimposed on the 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 (own vehicle position) is arranged on the map M. The own vehicle 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 characters, symbols, figures, or other objects.

[0081] In the example shown in FIG. 6(A), a message indicating the presence of the speed enforcement device 30, "This is a speed enforcement location", is displayed in the window W1. Further, the control unit 11 may output a voice of "This is a speed enforcement location" from the speaker 14. When the control unit 11 can determine the type of the speed enforcement device (for example, semi-fixed type, fixed type, mobile type) based on the characteristics of the received laser wave signal or other methods, it may perform control (an example of the third warning control) for issuing a warning including notification of the type of the speed enforcement device. The control unit 11 may notify, for example, by a message of "This is a semi-fixed speed enforcement location" as shown in FIG. 6(B). For example, fixed type or mobile type speed enforcement devices are an example of speed enforcement devices installed without being fixed to the fixing unit 50.

[0082] Next, the control unit 11 determines whether to end the process of FIG. 5 (step S4). The timing of ending the process is not particularly limited, but for example, it may be triggered by the power of the electronic device 10 being turned off by an operation of the operation unit 19 or the route guidance function being stopped. When it is determined "NO" in step S4, the control unit 11 returns to the process of step S1 and repeats the above process. When the control unit 11 no longer receives the laser light or a predetermined time has elapsed after it stops receiving the laser light, and thus the installation location of the fixing unit 50 no longer has a predetermined proximity relationship, the warning is stopped. When it is determined "YES" in step S4, the control unit 11 ends the process of FIG. 5 (step S5).

[0083] <1-2-2. Warning Based on Location Information> FIG. 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 processes described below. The timing of the start of the operation of the electronic device 10 may be the same as that of <1-1. Warning Control Based on Reception of Laser Light>.

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

[0085] If it is determined "YES" in step S13, the control unit 11 performs control (second warning control) to warn of the approach of the vehicle 40 to the installation location of the fixed unit 50 (step S14). By doing so, when the vehicle 40 approaches each fixed unit 50 (for example, each support column), the control unit 11 can warn of the approach to the installation location of the fixed unit 50. The warning in step S14 is issued in a situation where the vehicle is approaching the installation location but the electronic device 10 is not receiving the laser light. Therefore, at the installation location, it may be the case that enforcement is actually being carried out, or enforcement is being carried out but the laser light cannot be received for some reason. Therefore, the control unit 11 may issue a warning different from that in step S3 in step S14. More preferably, the control unit 11 issues a warning that allows the user to recognize that it is the installation location of the fixed unit 50. Further, the control unit 11 may display an image (for example, an icon or other object) indicating the existence of the installation location of the fixed unit 50 on the map M based on the position information of the installation location of the fixed unit 50.

[0086] FIG. 8 is a diagram showing an example of an alarm screen. The alarm screen shown in FIG. 8 is a screen in which a window W2 is superimposed on a map M. A message indicating the existence of an installation location, "This is a location where a speed enforcement device can be installed," is displayed in the window W2. Further, the control unit 11 may output a voice "This is a location where a speed enforcement device can be installed" from the speaker 14. In this way, based on the position information of the electronic device 10, the existence of the installation location of the fixing unit 50 can be notified, so that even if the electronic device 10 does not receive the laser light from the speed enforcement device 30, its existence can be notified. Further, since the alarm when the electronic device 10 does not receive the laser light is different from the alarm when it does, it is possible to expect an effect of reducing the user's misunderstanding and dissatisfaction due to the actual absence of the speed enforcement device 30.

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

[0088] <1-2-3. Combination of Alarm Based on Reception of Laser Light and Alarm Based on Position 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 Position 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 processes described below. The timing for the start of the operation of the electronic device 10 may be the same as that of <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. When it is determined as "YES" in step S13, the control unit 11 determines whether laser light has been received (step S2). When it is determined as "YES" in step S2, the control unit 11 performs control to alarm the approach to the speed enforcement device 30 (first alarm control) (step S3). When the process of step S3 is executed, the control unit 11 proceeds to the process of step S4. When it is determined as "NO" in step S2, the control unit 11 performs control to alarm the approach to the installation point of the fixing part 50 of the vehicle 40 (second alarm control) (step S14). In this way, when the vehicle 40 approaches each fixing part 50 (for example, each support column), the control unit 11 can alarm the approach to the installation point of the fixing part 50. When the process of step S14 is executed, the control unit 11 proceeds to the process of step S4. The processes of steps S4 and S5 may be the same as <1-1. Alarm control based on reception of laser light>.

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

[0091] An alarm indicating approach to the speed enforcement device 30 as described above may be an alarm indicating reception of a speed measurement signal from a simple speed enforcement device, but may particularly be an alarm indicating that a speed enforcement device is installed in a fixed part. For example, the electronic device 10 stores position information of a support column (an example of a fixed part) installed on a route such as an urban expressway for installing a semi-fixed obis as a speed enforcement device. Then, when the vehicle 40 approaches each support column, the control unit 11 issues an alarm indicating approach to the support column position for installing the semi-fixed obis (for example, an alarm saying "Approaching a support column where a semi-fixed obis can be installed!"). After that, if a speed measurement signal is received from a speed enforcement device (obis) before reaching the position of the alarmed support column, an alarm indicating reception of the speed measurement signal, simply saying "Received the enforcement laser", may be issued. However, it may be made to include content indicating that there is a speed enforcement device in the fixed part, such as "There is an obis at a support column where a semi-fixed obis can be installed! Pay attention to speed!", or an alarm including content indicating that a speed enforcement device is fixed to the fixed part 50 and content indicating reception of the speed measurement signal, such as "There is an obis at a support column where a semi-fixed obis can be installed! Laser received! Pay attention to speed!".

[0092] As described above, in the first embodiment, the electronic device 10 may determine that the speed enforcement device 30 is installed in the fixed part 50 by detecting reception of laser light or the like, which is a speed measurement signal. For example, when the laser light of the speed enforcement device 30, which is a laser type obis, is detected after an approach warning to the support column position (the position of the fixed part 50), it may be made to issue a further warning indicating that a semi-fixed obis exists at the support column.

[0093] [2. Second Embodiment] Instead of, or in addition to, determining the presence of the speed enforcement device 30 by receiving laser light, the electronic device 10 of the present embodiment may determine it by a method using a captured image. The electronic device 10 of the present embodiment communicates with an imaging device 70 (see FIG. 4) via a communication unit 17. The imaging device 70 images the 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. The algorithm for analyzing the captured image is not limited, but examples 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 that it is the installation location of the fixed unit 50 or the speed enforcement location. The predetermined image indicating the installation location of the fixed unit 50 may be an image of the appearance of the fixed unit 50. The predetermined image indicating the speed enforcement location may be an image of the appearance of the speed enforcement device 30, or may be a sign (in this embodiment, the sign 60 shown in FIG. 2) that may be installed at the installation location. Since a sign 60 warning of the enforcement may be installed about 1-2 km before the actual enforcement route, this sign can be used as a landmark for the speed enforcement location. In this way, for example, even if the fixed unit 50 or the speed enforcement device 30 has just been installed and their location information has not been registered in the database 181, the control unit 11 can issue an alarm.

[0094] FIG. 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 a process of recognizing a predetermined image indicating that it is the installation location of the fixed unit 50 or the speed enforcement location.

[0095] Next, the control unit 11 determines whether there is an installation point of the fixed unit 50 or a speed enforcement point based on the result of image recognition (step S23). If it is determined "YES" in step S23, the control unit 11 determines whether it is a speed enforcement point (step S24). When the speed enforcement device 30 or the sign 60 is recognized, the control unit 11 performs control to issue an alarm for approaching the speed enforcement point where speed enforcement is currently being carried out (first alarm control) (step S25). If it is determined "NO" in step S24, the control unit 11 performs control to issue an alarm in the case of the installation point of the fixed unit 50 (second alarm control) (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 determines whether to end the process of FIG. 10 (step S27). If it is determined "NO" in step S27, the control unit 11 returns to the process of step S21 and repeats the above process. If it is determined "YES" in step S27, the control unit 11 ends the process of FIG. 10 (step S28).

[0097] According to the present embodiment, even if the electronic device 10 fails to receive the laser light for some reason, an alarm can be issued, and the possibility that the electronic device 10 misidentifies other light as laser light and issues a false alarm can be reduced. In the present embodiment, the electronic device 10. Also, the determination that the speed enforcement device 30 is installed on the fixed unit 50 is made when it is recognized that the speed enforcement device appears in the image captured by the imaging device 70. In particular, it is preferable to specify the position of the image of the imaging device 70 corresponding to the position of the fixed unit 50, and to make the determination when it is recognized that the speed enforcement device appears 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 orbis, is installed on the support column during approach to the support column position, which is the position of the fixed unit 50, the control unit 11 may issue a warning indicating that there is a semi-fixed orbis on the support column.

[0098] In this embodiment, if an alarm is issued at too early a stage, the user may feel it is noisy. Therefore, the control unit 11 may change the alarm content by gradually increasing the tempo at a predetermined time difference (for example, a time difference corresponding to traveling about 500 m), and end the alarm within a few seconds after the speed enforcement device appears.

[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 the outline of the system of this embodiment. As shown in FIG. 11, there are various types of roads. In particular, on the road called zone 30 shown as area Ar1 in FIG. 11, the possibility of an increase in opportunities for speed enforcement exists, and it is particularly important to observe the speed limit of the vehicle 40. Therefore, when the vehicle 40 (that is, the electronic device 10) is present within the zone 30, the control unit 11 of the electronic device 10 also notifies (in other words, informs the user) the amount of speed over (that is, 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 position information (step S31). Next, the control unit 11 determines whether the position information indicates within zone 30 (step S32). If it is determined as "YES" in step S32, the control unit 11 performs control to issue an alarm regarding the speed difference (fourth alarm control) (step S33). For example, the control unit 11 issues a message such as "This is near zone 30. You are currently over the speed limit by 10 km / h. Please slow down." by voice. The control unit 11 may notify the amount over the speed limit in increments of, for example, 1 km / h, but it may also notify in increments of 5 km / h to prompt attention regarding the speed. Whether to notify the amount over the speed limit in this way or from what speed or above to notify can be freely set by the user's settings or other methods. On the other hand, if it is determined as "NO" in step S32, that is, when the current position is in Ar1 outside zone 30 or not close within a predetermined distance range from Ar1, the control unit 11 turns off the function of issuing an alarm regarding the speed difference. By doing so, the possibility of frequently being notified of the speed difference is reduced.

[0101] In view of the fact that this embodiment originally had a kind of common sense without a basis that it was not regulated when the speed was less than 15 km / h, it also serves as an enlightenment activity that this common sense no longer applies in zone 30, and it is also an idea obtained by the inventor considering an appeal to the user. Considering the actual situation of driving, zone 30 is more suitable. If the road attribute is a road where the reference speed such as the speed limit is known, it may be configured to notify the speed difference of roads with other attributes (green belt). 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 orbis that can monitor two lanes simultaneously. Fixing parts 50 (for example, columns) are installed at a plurality of points on the highway where speed suppression is necessary, and based on the accident occurrence situation, etc., the fixing part 50 to which the laser-type speed enforcement device 30 main body is attached is changed periodically (in this example, every month). Such an operation is conceivable. Also, as a problem of conventional speed enforcement devices, since they are expensive, it may be difficult to deal with urban expressways with many curves and many places where speed suppression is necessary. Under such problems, the following configuration may be adopted.

[0103] (1) The control unit 11 may issue an alarm including notification that a fixing part 50 exists at or ahead of a curve. This alarm includes notification that the curve is one that the vehicle 40 is about to travel on or is traveling on, and notification that a fixing part 50 exists ahead of this curve. The control unit 11 may output a message such as "There is a column of a semi-fixed orbis ahead of the right curve" to issue an alarm. This alarm can be issued not only by the semi-fixed speed enforcement device 30 but also by various types of speed enforcement devices (for example, fixed type, mobile type, etc.). By doing so, even if the user is driving on a route with poor visibility, the user can quickly grasp the installation location or the enforcement location.

[0104] (2) The control unit 11 may issue an alarm indicating that it is approaching the installation location of the fixed unit 50, and set the approach distance for issuing the alarm to the installation location of the fixed unit 50 to be longer than the reach distance of the laser light of the laser - type speed enforcement device. In this case, when the control unit 11 detects the laser light after issuing the alarm indicating that it is approaching the installation location of the fixed unit 50, it may further issue an alarm indicating that the speed enforcement device 30 fixed to the fixed unit 50 exists. Note that the distance for giving an approach warning when approaching to a predetermined distance to the fixed unit 50 may be set to be longer than the reach distance 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 by laser light as the speed measurement signal, it may be set to a distance longer than the reach distance of the laser light. For example, if the reach distance 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, while approaching the installation location of the fixed unit 50, that the speed enforcement device 30 is installed on the fixed unit 50 by the imaging device 70, it may issue an alarm indicating that the speed enforcement device 30 fixed to the fixed unit 50 exists. In this case, when the control unit 11 does not receive the laser light despite detecting that the speed enforcement device 30 is installed on the fixed unit 50 by the imaging device 70, it may notify that there is a high possibility that the speed enforcement device 30 was not operating.

[0106] (4) When the control unit 11 does not receive the speed measurement signal despite detecting from the image captured by the imaging device 70 in front of the vehicle 40 that the speed enforcement device is installed on the fixed unit 50, it may notify that there is a high possibility that the speed enforcement device was not operating. For example, when it is recognized from the image captured by the imaging device 70 that the laser - type semi - fixed orbis is installed on the support column but the laser light is not received, the control unit 11 may notify, for example, "There was a laser - type semi - fixed orbis on the support column, but the laser was not detected. It seems to be stopped." to indicate that there is a high possibility that the orbis was not operating.

[0107] [5. Fifth Embodiment] The electronic device which is an embodiment of the present invention may perform a process of posting to other devices that the speed enforcement device is not installed in the fixed part 50. On the premise of the configuration of the fifth embodiment described above, the other device is preferably the server device 200, but it is also possible to use the electronic device 10A mounted on another vehicle. The control unit 11 may issue an alarm indicating that it is approaching the fixed part 50 for which it has been recently posted that the speed enforcement device 30 is installed in the fixed part 50. For example, for those for which it has been recently posted that the speed enforcement device 30 is installed in the fixed part 50, the control unit 11 may issue an alarm (orbis approach alarm). Based on the installation period for each location where the speed enforcement device 30 is installed in the fixed part 50, it is preferable to provide another device (such as a server, etc.) that estimates the next moving time and moving location and distributes information to the electronic device 10. For example, based on the installation period for each location where the speed enforcement device 30 is installed in the fixed part 50, it is preferable to estimate the next moving time (and moving location) and distribute it from the server device 200 to this device. By doing so, it is possible to make other devices aware that the speed enforcement device was not installed in the fixed part 50.

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

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

[0110] Figure 14 is a sequence diagram showing the processing flow of the system 2 when data is transmitted from the electronic device 10A to the server device 200. When the control unit 11 of the electronic device 10A determines the installation location of the fixed unit 50 (step S101), it transmits the position information corresponding to the installation location to the server device 200 (that is, performs the posting process) (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). As the method for determining the installation location of the fixed unit 50 in step S101, the methods described in the above-described embodiments can be adopted. 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 the installation location, the position information of the estimated installation location therefrom, or the position information input by the user. The electronic device 10A may transmit the position information that is not registered in the database 181 among the position information of the installation location. By doing so, it is not necessary to transmit unnecessary data, and the server device 200 does not have to store unnecessary data.

[0111] FIG. 15 is a sequence diagram showing the processing flow of 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 location 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 location from the received distribution information and registers it in the database 181 (step S113). The control unit 11 then uses this location information for alarm control of the installation location. By doing so, even if the installation location increases or changes, the electronic device 10A can issue an alarm indicating that it is approaching the installation location.

[0112] In steps S101 and S102, the control unit 11 may post that the speed enforcement device 30 is not installed on the fixed unit 50. Also, for the speed enforcement device 30 that has been recently posted on the fixed unit 50, the control unit 11 may issue an alarm. For example, this alarm may be issued when there is a post within a predetermined time back from the current date and time. Further, the server device 200 may estimate the next movement time (and / or movement location) based on the installation period for each location where the speed enforcement device 30 is installed on the fixed unit 50 with respect to the transmission in the distribution information, and distribute it to the electronic device 10A.

[0113] When the number of already alarmed semi-fixed orbits reaches the number of semi-fixed orbits held by the prefectural police, any of the above-mentioned alarms may be suppressed at the installation position of the fixed unit 50 on that route hereafter. Suppressing the alarm may mean, for example, not issuing an alarm.

[0114] [6. Modification Example] The present disclosure is not limited to the above-described embodiments and can be appropriately changed without departing from the gist. (Modification Example 1) When the control unit 11 of the electronic device 10 recognizes the fixed unit 50 from the image captured by the imaging device 70 of the front of the vehicle 40, if the laser light is not received by the light receiving unit 12, it is preferable to suppress the control for issuing an alarm. In this case, suppressing the control for issuing an alarm means that, in addition to not issuing an alarm, there are methods such as reducing the volume, reducing the display, and lowering the alarm level compared to the case where the alarm is not suppressed even if it is issued. By doing so, although the fixed unit 50 exists, since speed enforcement is not being carried out, the provision of useless information to the user can be suppressed.

[0115] (Modification Example 2) In an urban area or the like, when moving directly from a situation where the volume of the electronic device 10 is lowered to a highway, the alarm sound may become difficult to hear due to road noise during high-speed driving because the volume is low. Therefore, when the control unit 11 of the electronic device 10 detects highway driving, it is preferable to set the volume related to the alarm (alarm volume) to a preset volume. This volume is preferably set to a volume that does not interfere with the recognition of the user's voice even during driving on the highway. By doing so, the recognition of the alarm sound on the highway can be enhanced. For example, the control unit 11 may set the volume as a volume obtained by adding a predetermined value to the volume being set so that the volume during driving on the highway is greater than during driving on a road other than the highway such as a general road. The determination of whether the vehicle is driving on the highway may be made based on position information and road information, or various known techniques can be adopted.

[0116] If it is difficult for the control unit 11 to detect that the vehicle is driving on the highway, it is preferable to set a volume related to the alarm (alarm volume) to a preset volume with a certain speed or higher as the volume variable point. With this method, the recognition of the alarm sound can be enhanced by changing the alarm volume when the speed increases regardless of the distinction between general roads and highways, and the omission of hearing the alarm sound can be reduced.

[0117] (Modification Example 3) Although the case where the semi-fixed speed control device supports the laser method has been described, the present invention can also be applied when warning of approaching the installation location of a speed control device that emits a speed measurement signal (measurement wave) of the radar method or other methods. For example, when the electronic device 10 determines that the speed control device 30 is installed in the fixed part 50, it may be performed by detecting that there has been reception of radio waves or other speed measurement signals (measurement waves) for measuring the speed of the vehicle.

[0118] (Modification Example 4) Some of the configurations and operations described in each of the above-described embodiments may be omitted or changed. For example, the fixed part 50 may not have one of the power supply part 51 and the line part 52, and any device may be used as long as it is used for the operation and installation of the speed control device 30. For example, when specifying the invention by the function related to <1-2-2. Warning Based on Position Information>, it may not have a receiving part for speed measurement signals.

[0119] The scope of the present invention is not limited to the configurations explicitly described in the specification, but also includes combinations of various aspects of the present invention disclosed in this specification within its scope. Among the present invention, the configuration for which a patent is sought is specified in the appended claims, but even a configuration that is not currently specified in the claims has the intention of making the configuration disclosed in this specification the claims in the future.

[0120] Note that the scope of the present invention is not limited to the configurations explicitly described in the specification, but also includes combinations of various aspects of the present invention disclosed in this specification within its scope. Among the present invention, the configuration for which a patent is sought is specified in the appended claims, but even a configuration that is not currently specified in the claims has the intention of making the configuration disclosed in this specification the claims in the future.

[0121] The invention of the present application is not limited to the configurations described in the above-described embodiments. The constituent elements of the above-described embodiments and modification examples may be arbitrarily selected and combined. Also, any constituent element of each embodiment and modification example may be arbitrarily combined with any constituent element described in the means for solving the invention or a constituent element embodying any constituent element described in the means for solving the invention. Regarding these, there is an intention to obtain rights in the amendment or divisional application of the present application. Even if there are descriptions such as "in the case of ~" or "when ~", it is not described as a configuration limited to that case or that time. The present application also discloses configurations that are not these cases or times, and has an intention to obtain rights. Also, the order described in the sequential descriptions is not limited to this order. The present application also discloses configurations in which some parts are deleted or the order is changed, and has an intention to obtain rights.

[0122] Also, due to the change to a design registration application, there is an intention to obtain rights for the overall design or partial design. Although the drawings depict the entire apparatus in solid lines, the drawings include not only the overall design but also partial designs claimed for a part of the apparatus. For example, not only can a part of the members of the apparatus be a partial design, but the drawings also include a partial design of a part of the apparatus regardless of the members. As a part of the apparatus, it may be a part of the members of the apparatus or a part of those members. Regarding the overall design, of course, there is an intention to claim as rights a partial design in which an arbitrary part of the solid-line part of the drawings is made into a dashed-line part. Also, regarding the modules, members, parts, etc. inside the housing of the apparatus, those shown in the drawings are all independently subject to transactions, and similarly, there is an intention to make a change to a design registration application and claim as rights.
