FIG. 1 shows an embodiment of the present invention. First, the components constituting the other vehicle abnormality detection device of the present invention will be described. In FIG. 1, reference numeral 1 indicates an own vehicle (hereinafter referred to as a vehicle), and reference numeral 11 indicates another vehicle traveling around the vehicle 1.
The vehicle 1 has a camera 2 that functions as an appearance information acquisition means inside the vehicle body. The camera 2 has a front camera 2a that shoots the front, a left side camera 2b that shoots the left side, a right side camera 2c that shoots the right side, and a back camera 2d that shoots the rear.

Further, inside the vehicle body of the vehicle 1, a communication device 3 that functions as an appropriate information acquisition means is arranged. The communication device 3 has a vehicle-to-vehicle communication unit 3a for vehicle-to-vehicle communication and a network communication unit 3b for communication between the vehicle 1 and the network. A display unit 4 is connected to the communication device 3, and the display unit 4 displays the content of inter-vehicle communication with another vehicle 11 by the communication device 3.
Further, a control means 5 for controlling each operation is connected to the camera 2 and the communication device 3. The control means 5 is composed of a well-known microcomputer having a CPU, ROM, RAM, and the like.

On the other hand, a communication device 13 having an inter-vehicle communication unit 13a and a network communication unit 13b is also arranged inside the other vehicle 11. A display unit 14 similar to the display unit 4 and a control means 15 similar to the control means 5 are connected to the communication device 13, respectively.

A first embodiment in the vehicle check system of the present invention will be described based on the above configuration. Since the vehicle check system of the present invention is premised on performing vehicle-to-vehicle communication, it first searches for another vehicle 11 capable of performing vehicle-to-vehicle communication with the vehicle 1, and then searches for a vehicle with the searched other vehicle 11. Start inter-vehicle communication. The vehicle-to-vehicle communication referred to here is not limited to the one that directly communicates between vehicles, and also includes the one that communicates between vehicles via a network.

When the vehicle-to-vehicle communication is started, the vehicle 1 starts a check operation for determining whether or not the other vehicle 11 is in a normal state. In the first embodiment, it is checked whether or not the other vehicle 11 has a failure or damage, and this check operation will be described with reference to the flowchart shown in FIG.
The vehicle 1 acquires an image of the other vehicle 11 by photographing the other vehicle 11 with the camera 2 (ST01). Further, the vehicle 1 acquires appropriate information of the other vehicle 11 from the other vehicle 11, that is, normal appearance information (dimensions in a normal state, unevenness of the outer surface of the vehicle body, positions of brake lamps and turn lamps, etc.) by inter-vehicle communication ( ST02).

Next, the control means 5 compares the acquired appropriate information with the image information which is the information of the captured image (ST03). At this time, the control means 5 functions as a comparison means, and in the first embodiment, it is checked whether or not a failure has occurred in the other vehicle 11 as a result of performing the comparison operation. As for the presence or absence of failure, it is checked whether there is any abnormality in the appearance of the other vehicle 11, that is, whether there is a dent in the bumper, the door, or the like. This comparison operation will be described based on the subroutine shown in FIG.
The control means 5 acquires appropriate appearance information of the other vehicle 11 as point cloud data from the appropriate information sent from the other vehicle 11 (ST11). Next, the control means 5 acquires the current appearance information of the other vehicle 11 as point cloud data from the image information captured by the camera 2 (ST12). Then, the control means 5 compares each point cloud data (ST13) and determines whether or not they are the same (ST14). If it is judged that they are the same, it is judged to be in a normal state because the current appearance is proper (ST15), and if it is judged that each data is different, the current appearance is not proper. Therefore, it is determined that there is a dent in the bumper, door, etc. (ST16). It should be noted that the same as used here does not mean only an exact match, and some errors are allowed.

Further, in step ST03, whether or not the brake lamp and the turn lamp are functioning normally, that is, whether or not the lamp is burnt out or malfunction is also checked by the comparative operation. This comparison operation will be described based on the subroutine shown in FIG.
The control means 5 acquires, in addition to the appearance information of the other vehicle 11, operation signals of the brake lamp and the turn lamp (operation signals of the brake pedal and the blinker, etc.) which are lamp operation information from the appropriate information sent from the other vehicle 11. (ST21). Next, the control means 5 acquires the current lighting state of the brake lamp and the turn lamp of the other vehicle 11 from the image information captured by the camera 2 (ST22). That is, the positions of the brake lamp and the turn lamp are grasped from the appearance information, and it is confirmed by the camera 2 whether or not the light source existing at the positions is lit. Then, the control means 5 compares the operation signal with the current lighting state (ST23) and determines whether or not both are the same (ST24). If it is determined that they are the same, it is determined that each of the current lamps is functioning normally (ST25), and if it is determined that they are different, each of the current lamps is functioning normally. Since it is not, it is judged to be an abnormal state in which the lamp is burnt out or malfunction occurs (ST26).

After the comparison is performed in step ST03, the result of the comparison is acquired (ST04), and it is determined whether or not the result is in a normal state (ST05). If the result of the comparison is normal, this flow is terminated, and if the result of the comparison is abnormal, the content "Your vehicle is abnormal" by vehicle-to-vehicle communication from vehicle 1 to other vehicle 11. Abnormal information is transmitted (ST06). At this time, the control means 5 functions as an abnormality determination means. As the abnormality information, failure information containing specific contents such as "the bumper is dented" or "the brake lamp is off" may be transmitted.

According to the above configuration, when there is an abnormality in the other vehicle 11, the user of the other vehicle 11 can notify in real time that the abnormality has occurred from the vehicle 1 to the other vehicle 11 by inter-vehicle communication. You can immediately know that your vehicle is in an abnormal state. As a result, it is possible to prompt the user of the other vehicle 11 for maintenance such as repair of the own vehicle at an early stage, and it is possible to prevent the occurrence of accidents and failures due to the abnormal state.
In addition, since the appropriate information is compared with the current appearance, it is possible to accurately detect an abnormality without erroneously detecting a dent in the appearance or the position of the lamp.

Next, a second embodiment of the present invention will be described. In this second embodiment, in the operation in the first embodiment shown in FIG. 2, when the comparison result in step ST05 is abnormal, as shown in FIG. 5, the other vehicle 11 is specified. Information, for example, the number plate information is acquired by photographing the number plate of another vehicle 11 with the camera 2 (ST07), and the acquired specific information and image information are transmitted to the server 21 shown in FIG. 1 by network communication (ST08). .. That is, the camera 2 functions as a specific information acquisition means for acquiring specific information, and the communication device 3 functions as a network communication means. The specific information acquisition means is not limited to this, and specific information may be acquired by, for example, vehicle-to-vehicle communication. Further, it is preferable to transmit the content determined to be abnormal at this time to the server 21.
With this configuration, the other vehicle 11 can be identified, and the server 21 that receives the information can send the abnormality information to the facility suitable for the content of the abnormality of the other vehicle 11, and the facility side that received the information sends the information to the other vehicle 11. Can be notified. For example, if the abnormality information is a dent in the bumper or the lamp is out, the abnormality information may be transmitted to the dealer. Further, by once transmitting the abnormality information to the facility, it is possible to notify the other vehicle 11 of the guidance or the like as necessary after confirming the abnormality content at the facility, so that unnecessary notification can be prevented.

As a modification of the second embodiment described above, when the number plate information of the other vehicle 11 is transmitted to the server 21 in step ST08 of the flowchart shown in FIG. 5, the position information of the other vehicle 11 is also transmitted to the server 21. It may be configured. In this embodiment, the position information of the vehicle 1 is used as the position information of the other vehicle 11. As the position information of the vehicle 1 used at this time, the position information of the navigation system mounted on the vehicle 1 may be used.

This check operation will be described with reference to the flowchart shown in FIG.
The vehicle 1 operates the camera 2 to acquire an image of the other vehicle 11 (ST31). In addition, appropriate information of the other vehicle 11 is acquired from the other vehicle 11 by vehicle-to-vehicle communication (ST32). Since the number of passengers is also visible from outside the vehicle, it is included in the appearance information.

Next, the control means 5 compares the acquired appropriate information with the image information (ST33). At this time, the control means 5 functions as a comparison means, and in the third embodiment, it is checked whether or not the other vehicle 11 is illegal as a result of performing the comparison operation.
This comparison operation will be described based on the subroutine shown in FIG.
The control means 5 acquires various information such as the total length, the total width, and the total height of the other vehicle 11 from the acquired appropriate information (ST41). Next, the control means 5 acquires the current appearance information of the other vehicle 11 as point cloud data from the image information captured by the camera 2 (ST42).
Next, the control means 5 acquires the maximum number of passengers of the other vehicle 11 from the other vehicle 11 by inter-vehicle communication, and determines whether or not the number of passengers is within the passenger capacity from the image information taken by the camera 2. (ST43).

The control means 5 then determines whether or not the length of the load is a specified value, that is, 1.1 times or less the total length of the other vehicle 11 (ST44). If it is within the specified value, the control means 5 then determines whether or not the width of the load is within the specified value, that is, within the total width of the other vehicle 11 (ST45). As for the shape of the load, the appearance information in the appropriate information is compared with the image information, and the portion other than the appropriate information in the image information is recognized as the load.
If it is within the specified value, the control means 5 then determines whether or not the total height of the loaded load is within the specified value, that is, 3.8 m (ST46). If it is within the specified value, it is judged to be a normal state because the current state of the other vehicle 11 is a legal state (ST47), the capacity is exceeded in step ST43, and even one is specified in each step ST44, ST45, ST46. If it does not correspond to the value, it is determined that the other vehicle 11 is in an abnormal state because the current state is not a legal state (ST48).

After the comparison is performed in step ST33, the result of the comparison is acquired (ST34), and it is determined whether or not the result is in a normal state (ST35). If the comparison result is in the normal state, this flow is terminated, and if the comparison result is in the abnormal state, the number plate information of the other vehicle 11 is acquired and the number plate information and the image information are transmitted to the server 21. To do. At this time, it is preferable to transmit the content determined to be abnormal to the server 21.
The server 21 that has received the information can transmit the number plate information of the other vehicle 11 and the information on the illegal state to the police, and can determine whether the police are really in the illegal state or have been notified. If it is illegal, the police will send a message to the other vehicle 11 via network communication stating that "your vehicle is in an illegal state" (ST36).

With this configuration, it is possible to notify the illegal vehicle that it is illegal, so that the user of the other vehicle 11 can grasp that the own vehicle is in an illegal state. As a result, it is possible to prevent accidents and breakdowns caused by the illegal state of the other vehicle 11.
In addition, since the current appearance is compared with the appropriate information, it is possible to accurately detect an abnormality without erroneously detecting the size of the load. The comparison of illegal states in the present embodiment is not limited to the load, and can be applied to illegal modifications (for example, wing having a size protruding from the vehicle width, mounting of sharp decorative parts, etc.).

In each of the above-described embodiments, the case where appropriate information is provided from the other vehicle 11 to the vehicle 1 by vehicle-to-vehicle communication has been described, but when the other vehicle 11 does not have the appropriate information, the distance from the other vehicle 11 to the vehicle-to-vehicle distance has been described.
