Hereinafter, a specific embodiment of the overspeed vehicle reporting device according to the present invention will be described with reference to the drawings.

(composition)
FIG. 1 is a block diagram showing an example of an overspeed vehicle notification device according to an embodiment of the present invention, and FIG. 2 is a flowchart showing a processing flow of the overspeed vehicle notification device shown in FIG.

The overspeed vehicle notification device 100 shown in FIG. 1 is an embodiment of the overspeed vehicle notification device according to the present invention, and is provided in the vehicle 200 (hereinafter referred to as the own vehicle 200). The overspeed vehicle notification device 100 notifies the outside of other vehicles traveling around the own vehicle 200 at a vehicle speed exceeding the legal upper limit speed (an example of a specified upper limit speed).

The overspeed vehicle notification device 100 includes another vehicle speed acquisition unit 10, an identification information acquisition unit 20, a legal upper limit speed acquisition unit 30, a determination unit 40, and a notification unit 50.

The other vehicle speed acquisition unit 10 acquires the speed at which a vehicle other than the own vehicle 200 (hereinafter, referred to as another vehicle) traveling around the own vehicle 200 is traveling. Since the overspeed vehicle notification device 100 notifies other vehicles that have exceeded the legal upper limit speed, for example, with respect to the own vehicle 200 traveling in compliance with the legal upper limit speed by the operation of automatic driving, etc. Cars run fast.

Here, in a situation where the other vehicle is traveling in front of the own vehicle 200, since the other vehicle moves away from the own vehicle 200, it is unlikely that the other vehicle will cause harm to the own vehicle 200. On the other hand, in a situation where the other vehicle is traveling behind the own vehicle 200, the other vehicle approaches the own vehicle 200, which may cause a rear-end collision or contact with the own vehicle 200.

Therefore, the overspeed vehicle notification device 100 mainly targets other vehicles traveling behind the own vehicle 200 among the surroundings of the own vehicle 200, but the overspeed vehicle notification device according to the present invention is itself. The report is not limited to other vehicles traveling behind the vehicle, and other vehicles traveling in front of or to the side of the own vehicle may also be subject to reporting.

The other vehicle speed acquisition unit 10 acquires, for example, the own vehicle speed acquisition unit 11 that acquires the speed (own vehicle speed) of the own vehicle 200, and the relative speed (other vehicle relative speed) of the other vehicle with respect to the own vehicle 200. The speed of another vehicle (other vehicle) based on the own vehicle speed acquired by the vehicle relative speed acquisition unit 12, the own vehicle speed acquisition unit 11, and the other vehicle relative speed acquired by the other vehicle relative speed acquisition unit 12. It is provided with a calculation unit 13 for calculating (speed). Specifically, the calculation unit 13 adds the relative speed of the other vehicle to the speed of the own vehicle to calculate the speed of the other vehicle.

Here, the own vehicle speed acquisition unit 11 receives the vehicle speed calculated by the own vehicle 200 based on the vehicle speed pulse or the like detected by the vehicle speed detection device 181 provided in the own vehicle 200, thereby causing the own vehicle speed. To get. Therefore, the own vehicle speed acquisition unit 11 does not detect the own vehicle speed, but may acquire the own vehicle speed by detecting the own vehicle speed.

The other vehicle speed acquisition unit 10 may directly acquire the other vehicle speed without using the own vehicle speed and the other vehicle relative speed.

The other vehicle relative speed acquisition unit 12 acquires the relative speed of the other vehicle with respect to the own vehicle 200 detected by the sonar device 120 and the radar device 130 provided in the own vehicle 200 from the sonar device 120 and the radar device 130. do.

In addition to the sonar device 120 and the radar device 130, the relative speed of the other vehicle is detected based on the time-series size change of the image of the other vehicle taken by the camera 110 provided in the own vehicle 200. Then, the detected relative speed of the other vehicle may be acquired by the other vehicle relative speed acquisition unit 12. Further, the relative speed of another company may be detected by using any two or more of the camera 110, the sonar device 120, and the radar device 130.

The identification information acquisition unit 20 acquires identification information for identifying another vehicle. The identification information for identifying the other vehicle is, for example, a character string displayed on the license plates provided on the front portion and the rear portion of the other vehicle, respectively.

This identification information can be detected, for example, by a camera 110 provided in the own vehicle 200 based on an image of another vehicle around the own vehicle 200, and the identification information acquisition unit 20 is detected by the camera 110. Acquire the detected identification information.

In addition, for example, with the advancement of vehicle-to-vehicle communication technology, another vehicle is provided with an identification information receiving unit that constantly or periodically transmits identification information of the other vehicle and the own vehicle 200 receives the identification information. In the case of the configuration, the identification information acquisition unit 20 may acquire the identification information received by the identification information receiving unit. In this case, the identification information is not limited to the character string displayed on the license plate, and may be a chassis number or the like.

The legal upper limit speed acquisition unit 30 acquires the upper limit speed (legal upper limit speed) stipulated by the Road Traffic Act or the like on the road on which the own vehicle 200 travels. The legal upper limit speed is detected by, for example, the legal upper limit speed detection device 150 provided in the own vehicle 200. Then, the legal upper limit speed acquisition unit 30 acquires the legal upper limit speed detected by the legal upper limit speed detection device 150 via, for example, the vehicle-mounted network 190.

The legal upper limit speed detection device 150 may be, for example, a camera. When the camera is applied as the legal upper limit speed detection device 150, the legal upper limit speed detection device 150 detects the legal upper limit speed from the image of the road sign (including the electric sign) taken by the camera by character recognition processing or the like. ..

In addition to the above-mentioned camera, the legal upper limit speed may be acquired from map data possessed by the information terminal device 160 provided in the own vehicle 200, such as a navigation device. The legal upper limit speed corresponding to each road is recorded in this map data, and the legal upper limit speed acquisition unit 30 acquires the legal upper limit speed recorded in the map data via the vehicle-mounted network 190.

Further, when the own vehicle 200 is driven by automatic driving, the legal upper limit speed may be included in the high-precision map information possessed by the own vehicle 200 and used for automatic driving. In this case, the legal upper limit speed acquisition unit 30 acquires the legal upper limit speed included in the high-precision map information via the vehicle-mounted network 190.

The statutory upper limit speed is a fixed upper limit speed stipulated by law, but if the upper limit speed is temporarily regulated due to an accident or congestion, the upper limit speed is lower than the statutory upper limit speed. May be limited to. Therefore, the statutory upper limit speed is an example of the specified upper limit speed including such a temporarily specified upper limit speed.

The determination unit 40 determines whether or not the other vehicle speed acquired by the other vehicle speed acquisition unit 10 exceeds the legal upper limit speed acquired by the legal upper limit speed acquisition unit 30.

Then, when the determination unit 40 determines that the speed of the other vehicle exceeds the legal upper limit speed, the reporting unit 50 determines the speed of the other vehicle (other vehicle speed) exceeding the legal upper limit speed of the other vehicle. , The data server 300 provided outside the own vehicle 200 is notified as the data associated with the identification information acquired by the identification information acquisition unit 20 and the position information and the time information for specifying the current position of the own vehicle 200. As described above, the data is output through the data communication ECU 182 provided in the own vehicle 200 via the vehicle-mounted network 190.

Here, the external data server 300 is connected to, for example, a police that controls traffic violations, a system that guides traffic information, and the like.

The own vehicle 200 has a vehicle speed control device 170 and a steering control device 180 connected to the in-vehicle network 190, and the own vehicle 200 is automatically driven by the control of the vehicle speed control device 170 and the steering control device 180. It has become.

(motion)
The operation of the overspeed vehicle notification device 100 configured as described above will be described with reference to the flowchart shown in FIG.

First, the own vehicle speed acquisition unit 11 acquires the own vehicle speed by starting the operation of the overspeed vehicle notification device 100 (S1). Following or in parallel with the acquisition of the own vehicle speed, the other vehicle speed acquisition unit 10 detects the surroundings of the own vehicle 200 (mainly, the own vehicle 200) detected by the camera 110, the sonar device 120, and the radar device 130. Acquire the presence of another vehicle (in the rear) (S2).

When the presence of the other vehicle is not acquired, that is, when the other vehicle is not detected (NO in S2), the overspeed vehicle notification device 100 ends the process.

When the existence of the other vehicle is acquired, that is, when the other vehicle is detected (YES in S2), the identification information acquisition unit 20 acquires the identification information for identifying the other vehicle that has acquired the existence (S3). ). Further, the other vehicle relative speed acquisition unit 12 acquires the relative speed of the other vehicle (S4).

Subsequently, the calculation unit 13 determines the speed of the other vehicle (other vehicle) based on the own vehicle speed acquired by the own vehicle speed acquisition unit 11 and the relative speed of the other vehicle acquired by the other vehicle relative speed acquisition unit 12. Speed) is calculated (S5).

Further, the legal upper limit speed acquisition unit 30 acquires the legal upper limit speed in which the own vehicle 200 is traveling (S6), and the determination unit 40 obtains the other vehicle speed acquired by the other vehicle speed acquisition unit 10 as the legal upper limit speed. It is determined whether or not the legal upper limit speed acquired by the acquisition unit 30 is exceeded (S7).

When the determination unit 40 determines that the speed of the other vehicle does not exceed the legal upper limit speed (NO in S7), the process returns to the process (S2) of waiting for the acquisition of the existence of the other vehicle.

When the determination unit 40 determines that the speed of the other vehicle exceeds the legal upper limit speed (YES in S7), the determination unit 40 acquires the speed of the other vehicle (the speed of the other vehicle) and the identification information acquisition unit 20. The data generated by associating the other vehicle identification information with the position information and the time information for specifying the current position of the own vehicle 200 is generated, and the reporting unit 50 acquires the data generated by the determination unit 40 ( S8).

Then, the reporting unit 50 transmits the acquired data to the data server 300 provided outside the own vehicle 200 through the data communication ECU 182 connected to the vehicle-mounted network 190 (S9), and the overspeed vehicle reporting device 100 Ends the process.

Since the external data server 300 is connected to, for example, the police that control traffic violations and the system that guides traffic information, the police and the like can identify information of other vehicles that are overspeeding vehicles, and the speed and position of other vehicles. Based on the information and time information, it is possible to encourage safe driving by asking other vehicles that have exceeded the speed not to exceed the speed.

The overspeed vehicle notification device 100 of the present embodiment automatically transmits the data (identification information, speed, position, location, etc.) of the overspeed vehicle detected around the own vehicle 200 to the external data server 300. However, when adding the data of the own vehicle 200 to be reported (identification information for identifying the own vehicle 200, etc.) to the above-mentioned data of the overspeed vehicle, the own vehicle is notified before the data is transmitted. 200 drivers may be asked to approve whether or not to allow transmission.

That is, since the data of the own vehicle 200 includes personal information, some drivers do not want to transmit such personal information. Therefore, the driver's approval is given to the overspeed vehicle reporting device before the data is transmitted. The approval reception unit that accepts data may be further provided so that the reporting unit transmits data only when the approval reception unit receives approval.

If such approval is requested one by one during driving, it is expected that the attention to the driving operation will be lowered or it will be troublesome. In that case, approval or non-approval may be selected and stored in advance before the operation, and in the data transmission scene, the process may be automated according to the approval or non-approval stored in advance. However, when the own vehicle 200 is in automatic driving, the configuration may be such that approval is requested one by one.

Further, the overspeed vehicle notification device 100 of the present embodiment notifies the external data server 300 when there is an overspeed vehicle. For example, the same other vehicle may be overspeeded a plurality of times. If there is, you may report each time there is an overspeed, but it is preferable to report only once in a certain period of time.

If multiple reports are made within a short period of time, there is a concern that other vehicles other than the own vehicle 200 will also be notified of overspeeded vehicles in multiple times, resulting in communication congestion. Moreover, since the effect of reporting multiple times is small, there is no problem if only one report is made.
