In addition, not only an owner name but what can identify uniquely the owner of this vehicle, such as an owner identifier, may be used.

The vehicle inspection information field is a field in which information related to vehicle inspection of the vehicle is stored.
In the present embodiment, an example is described in which the next vehicle inspection month and vehicle type are stored as vehicle inspection information, but the present invention is not limited to this.

   In the present embodiment, the IC tag reader / writer unit 3 of the vehicle A reads the vehicle information database 21 of the vehicle B, the vehicle C, and the vehicle D.

   The IC tag reader / writer 3 starts from the vehicle number fields of the vehicle information database 21 of the vehicle B, vehicle C, and vehicle D from the vehicle numbers “B”, “C”, and “D”, respectively, and the owner name field. The owner names “BBBB”, “CCCC”, and “DDDD” are acquired.

   When the IC tag reader / writer unit 3 acquires the vehicle number and owner name of the vehicle existing in the range where radio waves reach, the surrounding situation acquisition unit 42 receives the vehicle number and owner name from the IC tag reader / writer unit 3. Then, the vehicle number and the owner name are delivered to the impact detection unit 41.

   When the impact detection unit 41 receives the vehicle number and the owner name from the ambient condition acquisition unit 42, the impact detection unit 41 acquires the date, time, magnitude of impact, and surroundings obtained when the IC tag reader / writer unit 3 detects the impact. The vehicle number received from the situation acquisition unit 42 and the owner name are instructed to be stored in the own vehicle impact detection database 23.

   When the IC tag reader / writer unit 3 receives the instruction from the impact detection unit 41, the IC tag reader / writer unit 3 transmits / receives data to / from the IC tag unit 2 included in the host vehicle, and stores the date, time, magnitude of impact, and vehicle in the host vehicle impact detection database 23.

FIG. 4 illustrates only the vehicle A and the vehicle B.
This is because the impact detection unit 41 of the vehicle C and the vehicle D does not detect an impact by itself, and no record is stored in the own vehicle impact detection database 23.
That is, the record is stored in the own vehicle impact detection database 23 only when the impact detection unit 41 of the own vehicle detects an impact.

In this embodiment, an example in which the vehicle A and the vehicle B collide with each other is described, and the vehicle detection device 1 provided in the vehicle B also detects an impact.
Therefore, a record is stored as illustrated in FIG.

Referring to FIG. 4A, it becomes clear that the vehicle A has detected an impact with an impact level of “large” at “21:00” on “July 1”.
When the impact is detected, vehicles with vehicle numbers “B”, “C”, and “D” exist around the vehicle A, and the owners of the vehicles with the vehicle numbers are “BBBB”, It turns out that it is "CCCC" and "DDDD".

When the date, time, degree of impact, witness vehicle, and owner name are stored in the own vehicle impact detection database 23, the impact detection unit 41 makes the IC tag reader / writer unit 3 have the IC tag unit 2 of the own vehicle. The vehicle information database 21 is instructed to acquire the vehicle number and owner name.
And if the vehicle number and owner name of the own vehicle are acquired from the IC tag reader / writer unit 3, the impact detection unit 41 sends the date, time, magnitude of impact, vehicle number of the own vehicle, and Notify the owner name of the vehicle.

   Upon receipt of the notification from the impact detection unit 41, the ambient condition transmission unit 43 sends the date to the other vehicle impact detection database 22 of the IC tag unit 2 included in the other vehicle that is detected to be present around the IC tag reader / writer unit 3. Instruct to store the time, magnitude of impact, vehicle number of own vehicle, and owner name.

   When the IC tag reader / writer unit 3 receives an instruction from the surrounding state transmission unit 43, the date, time, and magnitude of the shock are stored in the other vehicle impact detection database 22 of the IC tag unit 2 of the other vehicle detected by the instruction of the surrounding state acquisition unit 42. Now, the vehicle number of the own vehicle and the owner name are stored (S2-4).

   Here, the structural example of the other vehicle impact detection database 22 is shown in FIG.

   The other vehicle impact detection database 22 illustrated in FIGS. 5A to 5D represents the other vehicle impact detection database 22 provided in the vehicles A to D, respectively.

   The other vehicle impact detection database 22 includes a date field, a time field, an impact degree field, and an impact detection vehicle / owner name field.

   The date field is a field in which the date when the impact is detected is stored.

   The time field is a field in which the time when the impact is detected is stored.

   The impact level field is a field in which the magnitude of the detected impact is stored.

The impact detection vehicle / owner name field is a field in which the vehicle number of the vehicle that detected the impact and the owner name of the vehicle are stored.
In this embodiment, the owner name is stored in parentheses in the vehicle number. However, the present invention is not limited to this, and any record configuration may be used as long as the vehicle and owner name can be distinguished. .

   Here, a record in which the impact detection vehicle / owner name field in FIGS. 5B to 5D is “A (AAAAA)” is stored.

   As described above, when detecting a shock, the vehicle detection device 1 according to the present embodiment acquires the vehicle number and the owner name of a vehicle existing around the vehicle, stores the vehicle number and the owner name in the own vehicle shock detection database 23, and The vehicle number and owner name of the host vehicle are also stored in the vehicle impact detection database 22 other than the vehicle.

Further, in this embodiment, the vehicle A and the vehicle B collide.
Therefore, the vehicle detection apparatus 1 of the vehicle B performs the same processing operation as that of the vehicle detection apparatus 1 of the vehicle A in order to detect an impact also in the vehicle detection apparatus 1 of the vehicle B.
When the vehicle B performs the same processing operation, a record as shown in FIG. 4B is stored in the own vehicle impact detection database 23 of the IC tag unit 2 of the vehicle B, and the vehicle A, which exists around the vehicle B, As shown in FIGS. 5A, 5 </ b> C, and 5 </ b> D, the other vehicle impact detection database 22 of the IC tag unit 2 of the vehicle C and the vehicle D has an impact detection vehicle / owner name field of “ The record “B (BBBB)” is stored.

   Thus, referring to the own vehicle impact detection database 23 in this embodiment, when the own vehicle detects an impact, the vehicle number and owner name of the vehicle existing around the own vehicle can be known, and a traffic accident Even if the witness does not appear at the time of occurrence, the witness can be specified based on the stored vehicle number and owner name.

Further, referring to the own vehicle impact detection database 23 and the other vehicle impact detection database 22 in this embodiment, it is possible to determine whether or not the other vehicle has also detected an impact in the vicinity of the date and time when the own vehicle detected the impact. .
For example, in the case of the vehicle A in FIG. 4, the impact is detected on “July 1” and “21:00”.
Further, looking at the vehicle A in FIG. 4, it is recorded that the vehicle B, which is another vehicle, detects an impact at the same date and time.
That is, by referring to the own vehicle impact detection database 23 and the other vehicle impact detection database 22, it becomes possible to identify the party of the traffic accident. Even if one of the parties escapes when the traffic accident occurs, , It is possible to identify the vehicle that escaped.

The vehicle information database 21, the other vehicle impact detection database 22, and the own vehicle impact detection database 23 constituting the IC tag unit 2 are an IC tag reader / writer provided in an information processing terminal carried by a police officer or an insurance agent. It is also possible to read in.
For example, when a traffic accident occurs, a police officer, an insurance agent, etc. read the IC tag unit 2 of the vehicle in which the traffic accident has occurred with an IC tag reader / writer, and another vehicle impact detection database 22 constituting the IC tag unit 2; Information recorded in the own vehicle impact detection database 23 can also be displayed.
The information read by the IC tag reader / writer unit 3 may be displayed on a display device provided in the vehicle.

   Here, a display example of the information stored in the IC tag unit 2 is shown in FIG.

   Display example 6-1 shows an example in which the information recorded in the other vehicle impact detection database 22 and the own vehicle impact detection database 23 is read by the IC tag reader / writer unit 3 of the vehicle A and displayed on the display device of the vehicle A. Is.

In the present embodiment, the date, time, witness vehicle, owner name, and impact detection vehicle recorded in the other vehicle impact detection database 22 recorded in the own vehicle impact detection database 23 are displayed.
