JP-A-2017-021821

A mobile orbis that makes the orbis movable is known. Since the mobile orbis can be installed anywhere, it is difficult to register the position information in advance in an electronic device or the like and notify the user of its existence.

Further, a laser type orbis that measures the traveling speed of a vehicle by irradiating a laser beam instead of a microwave can be considered. Laser light has higher directivity than microwaves, and it is difficult for an electronic device installed in a moving vehicle to receive the laser light at a long distance. It is possible to receive the laser beam from the mobile orbis at a short distance, but even if the laser beam is received several tens of meters before the mobile orbis and notifies the driver, the driver speeds the vehicle. It may not be possible to sufficiently reduce the speed of the vehicle and prevent the vehicle from overspeeding.

One aspect of the present disclosure is to notify the user in advance of the existence of an automatic speed violation control device using laser light, and to suppress overspeeding of the vehicle.

One aspect of the present disclosure is an electronic device mounted on a vehicle, which includes a position detection unit, a laser light receiving unit, a public communication unit, a notification unit, and a control unit. The position detection unit is configured to detect the current position of the electronic device. The laser light receiving unit is configured to receive the laser light emitted from the automatic speed violation control device. The public communication unit is configured to connect to a public line and perform communication. The notification unit is configured to notify the driver of the vehicle. The control unit includes a public transmission processing unit, a public reception processing unit, and a notification processing unit. The public transmission processing unit indicates the control position information indicating the current position of the electronic device when the laser light is received by the laser light receiving unit, or the position of the automatic speed violation control device estimated based on the light reception position. Is configured to be transmitted to a public line via the public communication unit. The public reception processing unit is configured to receive the control position information transmitted from an electronic device mounted on another vehicle to the public line from the public line via the public communication unit. The notification processing unit notifies the notification unit of the existence of the automatic speed violation control device based on the current position detected by the position detection unit and the position indicated by the control position information received by the public reception processing unit. I do.

The laser beam emitted from the automatic speed violation control device is received by the laser light receiving unit at a relatively short distance. Therefore, the light receiving position and the position of the automatic speed violation control device are close to each other. According to the above configuration, the automatic speed violation control device estimated based on the light receiving position or the light receiving position from the electronic device mounted on another vehicle that received the laser beam emitted from the automatic speed violation control device. It is possible to receive control position information indicating the position. Therefore, the control position information can be received at a point far from the automatic speed violation control device to the extent that the speed can be sufficiently reduced. Therefore, it is possible to notify the driver in advance of the existence of the automatic speed violation control device using the laser beam and suppress the overspeed of the vehicle.

According to these configurations, the user only has to contract with the communication company for the communication device in order to connect to the public line, and does not need to make a separate contract for the electronic device. Therefore, the communication cost can be reduced as compared with the configuration in which the electronic device is directly connected to the public line.
In one aspect of the present disclosure, the public communication unit may connect directly to the public line without going through a communication device that can connect to the public line. According to such a configuration, it is possible to connect to a public line without a communication device and to send and receive control position information.

One aspect of the present disclosure may further include a specific communication unit configured to perform communication by a specific low power radio, and the control unit may further include a specific transmission processing unit and a specific reception processing unit. The specific transmission processing unit is configured to directly transmit the control position information to another electronic device existing in the communication range of the specific low power radio via the specific communication unit. The specific reception processing unit is configured to directly receive the control position information from other electronic devices existing in the communication area via the specific communication unit. The notification processing unit performs notification processing based on the current position detected by the position detection unit and the position indicated by the control position information received by the specific reception processing unit. The term "direct transmission" as used herein means transmission without going through a public line, a base station for wireless communication, or the like. Similarly, "direct reception" means receiving without going through a public line, a base station for wireless communication, or the like.

According to such a configuration, even if the public line cannot be used by the other electronic device, the control position information can be transmitted and received to and from the other electronic device by the specified low power radio. As a result, compared with the configuration in which the control position information is transmitted and received only via the public line, the existence of the automatic speed violation control device using the laser beam can be further notified to the driver in advance, and the overspeed of the vehicle can be suppressed.

In one aspect of the present disclosure, the notification processing unit starts the notification processing on condition that the distance between the current position detected by the position detection unit and the position indicated by the received control position information is within a certain distance.

Here, when the control unit 35 accesses the server 60 one or more times after the power of the electronic device 30 is turned on and receives data including the light receiving position information, the control unit 35 specifies from the time of the previous reception. Determine if time has passed. That is, in the present embodiment, data is received at regular time intervals (specified time). This specified time can be set by the user, and can be selected from, for example, 10 minutes, 30 minutes, 1 hour, and the like. If no data has been received from the server 60 at the time of executing SC01, it is determined that the specified time has elapsed in SC01.

When the control unit 35 determines that the specified time has not elapsed in SC01, the control unit 35 ends the public line reception process.
On the other hand, when the control unit 35 determines that the specified time has elapsed in the SC01, the control unit 35 shifts to the SC02, specifies the range, and receives the data from the server 60 by the wireless communication unit 23 via the public line 70.

The valid time is set in. Specifically, the remaining time obtained by subtracting the elapsed time from the time indicated by the received light reception time information from the predetermined set time is set as the effective time. Then, the data whose valid time has become zero is determined to be expired data. The above-mentioned set time (and thus the effective time) can be set by the user, and the user selects from, for example, 24 hours, 1 week, 1 month, and the entire period.

When the control unit 35 determines that the internal data includes the expired data in the SD01, the control unit 35 shifts to the SD02 and deletes the expired data from the storage unit 26. When the control unit 35 executes SD02, the control unit 35 shifts to SD03.

On the other hand, when the control unit 35 determines in the SD01 that there is no expired data in the internal data, the control unit 35 skips the above-mentioned SD02 and shifts to the SD03.
Subsequently, in SD03, the control unit 35 starts receiving data by the specified low power radio.

In SD05, the control unit 35 determines whether or not the internal data includes data near the position indicated by the light receiving position information received in SD04 (hereinafter referred to as “corresponding point”). That is, in SD05, it is determined whether or not the light receiving position information indicating the position (point) indicated by the light receiving position information received by SD04 is already stored in the storage unit 26.

When the control unit 35 determines in SD05 that the internal data includes data near the corresponding point, the control unit 35 shifts to SD06 and updates the valid time of the corresponding point. That is, the control unit 35 replaces the effective time of the corresponding point with the effective time obtained by subtracting the elapsed time from the time indicated by the received light reception time information received by SD04 from the set time. When the control unit 35 executes SD06, the control unit 35 ends the specific low power reception process shown in FIG.

On the other hand, when the control unit 35 determines in SD05 that there is no data near the corresponding point in the internal data, the control unit 35 shifts to SD07 and sets the position indicated by the received light receiving position information received by SD04 and the time indicated by the received light receiving time information.

By transmitting to the device 30, the position information of the mobile orbis 10 can be received at a point where the electronic device 30 (and thus the vehicle 300) is distant enough to sufficiently slow down the speed. Therefore, it is possible to notify the driver of the vehicle 300 in advance of the existence of the mobile orbis 10 using the laser beam and suppress the overspeed of the vehicle 300.

Further, since the light receiving position information is received via the public line 70, the light receiving position information can be acquired anywhere in the country. That is, the light receiving position information can be received in a wider range than when the light receiving position information is received by the specific low power radio.

Further, since the light receiving position information is transmitted to the server 60 via the public line 70, for example, the dedicated application software is installed on the mobile information terminals 40 and 50, and the light receiving position information (light receiving position information () is transmitted via the mobile information terminals 40 and 50. As a result, the position information of the mobile Orbis 10) can be confirmed. Therefore, the convenience of the user can be improved.

(2) In the present embodiment, the electronic devices 20 and 30 perform wireless communication of the Bluetooth standard or the Wi-Fi standard with the mobile information terminal 40 that can be connected to the public line 70, and via the mobile information terminals 40 and 50. Connect to the public line 70. Therefore, in order to connect to the public line 70, the user only needs to make a contract with the communication company for the mobile information terminals 40 and 50, and does not need to make a separate contract for the electronic devices 20 and 30. Therefore, the communication cost can be reduced as compared with the configuration in which the electronic devices 20 and 30 are directly connected to the public line 70.

Therefore, the presence of the mobile Orbis 10 can be notified to the driver from a point separated from the received light receiving position by a certain distance.
(4) In the present embodiment, the electronic device 30 includes a wireless communication unit 33 configured to communicate with an external device by the specific low power radio, and other electronic devices existing in the communication range of the specific low power radio. The light receiving position is directly transmitted and received via the device 20 and the wireless communication unit 33. Then, the electronic device 30 performs notification based on the current position detected by the position detection unit 31 and the light receiving position indicated by the light receiving position information received by the wireless communication unit 33.

Therefore, even in a situation where the public line 70 cannot be used by the other electronic device 20, the light receiving position information can be transmitted and received to and from the other electronic device 20 by the specified low power radio. As a result, the presence of the mobile Orbis 10 can be further notified to the driver in advance and the speed overrun of the vehicle can be suppressed as compared with the configuration in which the light receiving position information is transmitted and received only via the public line 70. Further, the light receiving position information can be transmitted / received to / from another electronic device 20 without necessarily concluding a contract for using the public line 70 with the communication company. In other words, communication costs can be reduced.

In the present embodiment, the light receiving position information corresponds to the control position information, the wireless communication units 23 and 33 correspond to the public communication unit and the specific communication unit, the display units 24 and 34 correspond to the notification unit, and the mobile information. The terminals 40 and 50 correspond to communication devices. Further, SA02 corresponds to processing as a public transmission processing unit, SB02 corresponds to processing as a specific transmission processing unit, SC02 corresponds to processing as a public reception processing unit, and SD03 and SD04 serve as specific reception processing units. SE03 corresponds to the processing as the notification processing unit.

(1) In the above embodiment, the driver is notified by displaying the alarm screen on the display units 24 and 34, but the method of notifying is not limited to this. For example, a sound output unit that outputs sound may be mounted on electronic devices 20 and 30, and notification may be performed by causing the sound output unit to output sound. Further, for example, a light emitting body such as an LED may be mounted on the electronic devices 20 and 30, and the light emitting body may be made to emit light to perform notification. In particular, at least one of display, sound and light may be used for notification. When the sound output unit notifies, the sound output unit corresponds to the notification unit, and when the light emitting body notifies, the light emitting body corresponds to the notification unit.

(2) In the above embodiment, a mobile information terminal is exemplified as a communication device, but the communication device is not limited to this. The communication device may be a wireless LAN access point or the like other than the mobile information terminal.

(3) In the above embodiment, LoRA is exemplified as a standard for the specified low power radio, but a standard for the specified low power radio other than LoRA may be used. As such a standard, for example, SIGFOX, Wi-Fi HaLow, Wi-SUN, RPMA, Flexnet, IM920 and the like may be used.

In other words, the electronic devices 20 and 30 may be connected to the public line 70 without using the tethering function of the mobile information terminals 40 and 50 and the like. According to such a configuration, the electronic devices 20 and 30 can be connected to the public line 70 without a communication device, and the light receiving position information and the control position information can be transmitted and received to and from the server 60.
(5) In the above embodiment, when the laser light is received by the laser light receiving unit 22, the light receiving position information and the like are automatically transmitted from the electronic devices 20 and 30, but the transmission timing is not limited to this.

You may. The data referred to here is data including light receiving position information and light receiving time information. That is, the processes corresponding to SD01 and SD02 in FIG. 5 may be executed on the server 60. As a result, only the data whose effective time is not zero is stored in the server 60. Then, when the electronic devices 20 and 30 receive the data from the server 60, the data whose effective time is not zero may be received.

(7) In the above embodiment, the light receiving position information or the like may be transmitted / received by only one of the public line 70 and the specified low power radio.

In this case, for example, the position of the mobile orbis irradiated with the laser beam may be estimated based on the light receiving position, the direction in which the laser beam is irradiated, and the intensity of the laser beam. Then, the control position information indicating the estimated position may be transmitted / received via the public line 70 or the specified low power radio.

(9) In the above embodiment, the reliability may be set for the light receiving position information transmitted to the public line 70, and thus the picking position information. For example, when control position information indicating the same point is transmitted from a plurality of electronic devices to the server 60, it is highly probable that the mobile Orbis 10 exists at that point. Therefore, for example, when the control position information indicating the same position is transmitted from a plurality of electronic devices 20, 30 and the like to the public line 70, the reliability may be set according to the number of transmissions. In this case, the reliability may be set higher as the control position information indicating the position where the number of transmissions is large is increased. Then, the electronic devices 20, 30 and the like may receive only the control position information having a reliability of a predetermined degree or more via the public line 70.

The traveling direction information is information indicating the traveling direction of the vehicle when the vehicle equipped with the electronic device passes through the approach point and enters the specified range. The position information and the traveling direction information of the approach point are set manually or automatically in advance. The set data may be stored in advance in the storage unit 26, or may be received from an external server 60 or the like. Then, when the vehicle 200 or the like passes the approach point in the traveling direction specified by the traveling direction information, the notification may be started.

In other words, the electronic devices 20 and 30 include the position information of the plurality of approach points set near the boundary between the inside and the outside of the specified range based on the position indicated by the received control position information, and the plurality of said. When the vehicles 200 and 300 approach the position indicated by the received control position information, which is set for each of the approach points, the travel direction information indicating the travel direction when traveling at the approach point is acquired. Then, in the electronic devices 20 and 30, based on the acquired position information of the approach point and the travel direction information, the vehicles 200 and 300 set any of the plurality of approach points as the travel direction information set at the approach point. The notification is started when the vehicle passes in the traveling direction specified by.

Even if the distance between the current position of the electronic devices 20 and 30 and the position indicated by the control position information is within a certain distance, the vehicles 200 and 300 equipped with the electronic devices 20 and 30 move to the position indicated by the control position information. When not approaching the formula Orbis 10, there is little need to give notification.
