Yes. This collision result data is data indicating how much damage is caused to the vehicle body and the occupant. The vehicle manufacturer server 8 then determines the attribute of the collision target (whether it is a roadside structure or a large vehicle, etc.), the collision position of the obstacle, the collision direction, the collision speed, and the occupant information (presence / absence of occupants and seat belt wearing state) When accident data (accident status) comprising various data such as height and vehicle information is received from the information center 4, the transmitted accident status is compared with stored data (experimental accident data). Then, it is estimated that the accident data sent and the collision result data corresponding to the same or substantially the same experimental accident data are damage to the accident vehicle that sent the accident situation. Further, when a certain degree of damage occurs near the position of the fuel tank, fuel leakage is estimated.
[0034]
If the same or almost the same experimental accident data is not found, the experimental accident data closest to the accident situation is adopted on the side where the degree of damage is increased, and the accident result is sent to the accident result data corresponding to the experimental accident data. It is presumed that the car was damaged. For example, when the relative speed (collision speed) data during the experiment is taken every 10 km / h, and the collision speed based on the actual accident data is 54 km / h, the collision result data corresponding to the experimental accident data of 60 km / h. Will be adopted.

If YES in step S7, that is, if the dispatch information is received, the process proceeds to step S8, and based on the information received in step S7, “two ambulances headed there. Arrival time is scheduled for 17:30 The information regarding the ambulance such as “The tow vehicle has headed over there. Information regarding the rescue vehicle such as arrival time is scheduled for 18:00” shown in FIG. 6 is displayed on the display screen 44.
[0041]
Next, it progresses to step S9 and it is determined whether the damage information from the information center side was received. If NO in step S9, the information center side determines that the vehicle is slightly damaged, and the process ends. If YES in step S9, that is, if damage information is received, the process proceeds to step S10, and information on the degree of vehicle damage (body damage) as shown in FIG. 7 is displayed based on the information received in step S9. It is displayed on the screen 44.
[0042]
Next, the process proceeds to step S11, and it is determined whether or not there is a repair estimate request from the driver. This determination is made based on whether or not an “estimate request” button arranged on the information screen regarding damage has been pressed. If NO in step S11, that is, if it is determined that the “request for quotation” button has not been pressed, the process proceeds to step S12 to determine whether or not the “cancel” button on the screen has been pressed.
[0043]
If YES in step S12, that is, if it is determined that the “CANCEL” button has been pressed, the process proceeds to step S13, the screen display is turned OFF, and the process ends. On the other hand, if it is determined in step S12 that NO or the “cancel” button has not been pressed, the process proceeds to step S14, where it is determined whether or not a predetermined time has elapsed.
[0044]
If YES in step S14, that is, if it is determined that a predetermined time has elapsed, the process proceeds to step S13, the screen display is turned OFF, and the process is terminated. If NO in step S14, that is, if it is determined that the predetermined time has not elapsed, the process returns to step S11, and it is determined again whether there has been a repair estimate request from the driver.
[0045]
If YES in step S11, that is, if it is determined that the “estimate request” button has been pressed, the process proceeds to step S15, a request for quotation is transmitted to the information server 4, and the process further proceeds to step S16 to estimate information from the information server 4. Continue to determine whether or not. When YES is received in step S16, that is, when estimate information is received, the process proceeds to step S17, and based on the information received in step S16, estimate information related to the repair estimate as shown in FIG. In the present embodiment, in addition to the estimated amount, the estimate information screen includes the address of the supplier who made the estimate, a telephone number, a route from the current position, and a “cancel” button.
[0046]
Next, in step S18, it is determined whether or not the “cancel” button on the estimate information screen has been pressed. If YES in step S18, that is, if it is determined that the “cancel” button has been pressed, the process proceeds to step S13, the screen display is turned OFF, and the process is terminated. If NO in step S18, that is, if it is determined that the “cancel” button has not been pressed, the process returns to step S17 and the estimated information continues to be displayed.
[0047]
Next, the vehicle accident analysis operation of the information server 4 in the vehicle accident analysis system 1 of the present embodiment will be described along FIG. FIG. 9 is a flowchart showing a vehicle accident analysis process performed by the information server 4.
[0048]
When the communication means 50 of the in-vehicle device 6 is activated and connected via the network 2, the vehicle accident analysis process is started (step S20). Next, it is determined whether or not accident occurrence information and various accident data (accident status) have been received from the in-vehicle device 6 (step S21). If NO in step S21, that is, if no accident occurrence information and various accident data (accident status) have been received, the process proceeds to step S22 to determine whether or not a predetermined time has elapsed since the start of communication. If YES in step S22, that is, if a predetermined time has elapsed, it is determined that the accident has been avoided, and the process is terminated. If NO in step S22, that is, if the predetermined time has not elapsed, the process returns to step S21 again.
[0049]
When YES in step S21, that is, when accident occurrence information and various accident data (accident situation) are received, the process proceeds to step S23, and the vehicle manufacturer requesting estimation of vehicle damage based on the vehicle type data included in the accident data. The process proceeds to step S24, and the accident data sent from the accident vehicle is transmitted to the vehicle manufacturer server 8 of the selected manufacturer. Further, the vehicle occupant is inquired about the degree of vehicle damage and occupant damage (step S25), and it is determined whether or not there is a valid answer from the occupant (step S26).
[0050]
If NO in step S26, that is, if a valid answer cannot be obtained, the process proceeds to step S27, and the process waits for an answer from the maker server 8 that transmitted the accident data in step S24. Estimate and request relief from each rescue organization.
[0051]
If YES in step S26, that is, if a valid response is obtained, the response from the occupant is more reliable, so the response from the occupant server 8 is not adopted and the accident is caused based on this response from the occupant. Vehicle damage and occupant damage of the vehicle are set (step S29), and relief is requested from each rescue organization (step S28).
[0052]
In addition, as a kind of organization in which a relief request is made, and the content of relief, there exist the following, for example.
(1) Firefighting 10
When a fuel leak is estimated, the fire engine will be dispatched to the accident site, the ambulance will be dispatched to the site, depending on the number of occupants with a degree of damage of 3 or 4, and if the degree of damage is 5 or more , Request the dispatch of paramedic to the site based on the location information data of the accident vehicle. Furthermore, based on the data related to the occupant, the occupant's physical disability, presence / absence / content of illness, presence / absence of pregnancy, blood type, and the like may also be communicated to perform an appropriate treatment. On the other hand, dispatch information (scheduled arrival time) is obtained from the fire department.
(2) Police 12
Accident occurrence information and the degree of vehicle damage and passenger damage are reported together with the location information data of the accident vehicle.
(3) Road service 14
If self-propelled is not possible, request the dispatch of an accident vehicle removal worker, a tow vehicle, etc. to the accident site, and obtain dispatch information (scheduled arrival time on site) from the road service.
(4) Road management center 16
Accident occurrence information and the possibility of fuel leakage are notified together with the location information data of the accident vehicle, and a notice on the bulletin board and broadcast to the vehicles near the site is requested.
[0053]
After the rescue request is made, the process proceeds to step S29, and it is determined whether or not the degree of vehicle damage is 3 or 4 and 5 (with fuel leakage). If NO in step S29, that is, if the degree of vehicle damage is 1 or 2, and there is no fuel leakage, the process ends. If YES in step S29, that is, if the degree of vehicle damage is 3 or 4, or there is a possibility of fuel leakage, the process proceeds to step S30, and the vehicle is sent with damage information as shown in FIG. Then, the process proceeds to step S31, and it is determined whether or not there is a request for quotation from the driver within a predetermined time.
[0054]
If NO in step S31, that is, if it is determined that there is no request for quotation within a predetermined time, the process ends. If it is determined YES in step S31, that is, if there is a request for quotation within a predetermined time, the shortest repairable dealer (repair factory) is searched from the accident site, and an estimate is requested from this dealer (step S32). It waits for an answer to the estimate (step S33). When the answer to the estimate is obtained, the estimated amount and the position of the dealer are notified to the accident vehicle in step S34 (FIG. 8), and the process is terminated.
[0055]

FIG. 9 is a flowchart showing a vehicle accident analysis process performed by the vehicle manufacturer server 8.
[0056]
When the vehicle manufacturer server 8 receives the accident data and the request for estimating the degree of vehicle damage from the information center 4 via the network 2, the vehicle manufacturer server 8 starts a vehicle accident analysis process (step S40). Subsequently, it progresses to step S41 and it is determined whether the deviation of the accident data sent and the experimental data memorize | stored is more than predetermined value. If NO in step S41, that is, if the deviation is less than the predetermined value, the process proceeds to step S42, where vehicle damage is estimated based on the stored experimental data during vehicle development, and the estimation result is sent to the information center 4 (step S41). S44) The process ends.
[0057]
On the other hand, if YES in step S41, that is, if the deviation is greater than or equal to a predetermined value, the process proceeds to step S43, and among the stored experimental data at the time of vehicle development, the experimental data closest to the accident situation is adopted on the side where the degree of damage is large. To do. For example, if the collision angle of the sent accident situation (accident data) is 75 degrees and there is no 75 degree data in the stored data and there is 90 degree data, the 90 degree data is adopted. The Then, it is estimated that the collision result data corresponding to the experimental data is damage caused by the accident vehicle that has sent the accident situation, the estimation result is sent to the information center 4 (step S44), and the process is terminated.
[0058]
