[0019]
Further, the accident situation recording device 10 includes a partner situation acquisition section 26 for acquiring the running situation of the other car, which is output by the other car of the car accident when the accident detection section 18 detects the accident of the car. The partner status acquisition unit 26 may further obtain the name, user, vehicle type, inspection history, automobile insurance insurance company, and security number of the partner vehicle from the partner vehicle. It should be noted that there may be a plurality of other vehicles. In this case, the partner status acquisition unit 26 obtains each traveling status from a plurality of partner vehicles.
[0020]
As described above, the accident situation recording device 10 outputs the traveling situation of the other vehicle to the negligence diagnosis server 50 together with the traveling situation of its own automobile. Therefore, the accident situation recording device 10 can output the occurrence situation of the accident including the driving situation of the other vehicle to the negligence diagnosis server 50 in detail and objectively.
[0021]
Further, the accident situation recording device 10 includes a road situation acquisition unit 22 that acquires a road situation when a car passes from an external road situation transmission device. Then, the situation output unit 20 outputs the acquired road situation to the negligence diagnosis server 50 in association with the traveling situation of the automobile.

With the above configuration, the negligence diagnosis system 100 can objectively and quickly diagnose the negligence of the vehicle when an automobile accident occurs.
[0026]
FIG. 2 shows an example of the data format of the negligence database 54. The negligence database 54 stores the content of negligence in driving a car in an automobile accident in association with the degree of negligence, which is the degree of negligence according to the type of negligence. The negligence is, for example, a speed violation or a signal violation. The degree of negligence is associated with each type of negligence according to the degree that may cause an accident. For example, in the case of a speeding violation, a higher speed exceeding the legal speed is more likely to cause an accident, and thus a higher degree of fault is associated. As an example of the speed violation, a fault degree 3 is associated with a speed violation of 10 to 30 km / h, and a fault degree 10 is associated with a speed violation of 50 to 100 km / h. Further, since a signal violation is more likely to cause a serious accident than a lane change prohibition violation, a fault degree (8) larger than the fault degree (3) of the lane change prohibition violation is associated.
[0027]
Accordingly, if the negligence diagnosing unit 52 analyzes the driving situation of the vehicle at the time of the accident and determines the details of the negligence of the vehicle, the negligence diagnosis unit 52 refers to the negligence database 54 based on the determined negligence contents, and Degree can be extracted.
[0028]
FIG. 3 is a flowchart showing an operation in which the accident situation recording device 10 records and outputs a traveling situation. First, the positioning unit 12 measures the position of an automobile based on positioning signals received from, for example, the quasi-zenith satellite 200 and the GPS satellite 300 and the map information stored in the map database 24 (S100). The positioning unit 12 measures the position of the vehicle based on the positioning signals from the GPS satellites 300 and the quasi-zenith satellites 200 with an accuracy capable of determining the traveling lane of the vehicle. The road condition acquisition unit 22 acquires the surrounding road condition from an external road condition transmitting device (S102). The road condition acquisition unit 22 acquires, as an example of the road condition, the state of the surrounding signals when the vehicle passes from the road condition transmitting device. The road condition acquisition unit 22 may acquire, as another example of the road condition, lane regulation, speed regulation according to weather conditions, and congestion information from the road condition transmission device.
[0029]
Next, the recording unit 14 records the history of the position of the vehicle measured by the positioning unit 12 as the traveling state of the vehicle (S104). The recording unit 14 further records the surrounding road conditions acquired by the road condition acquisition unit 22 in association with the traveling conditions. Next, when the accident detecting unit 18 detects an accident of the vehicle (S106), the recording stop unit 16 stops recording the traveling state on the recording unit 14 (S108). If the accident detection unit 18 does not detect an accident in step 106, the accident situation recording device 10 returns to step 10 and measures the position of the automobile.
[0030]
Next, the partner status acquisition unit 26 determines whether or not the traveling status of the partner vehicle can be acquired from the partner vehicle of the accident (S110). If it is determined in step 110 that the traveling status of the other vehicle can be acquired, the other-party status acquiring unit 26 acquires the traveling status of the other vehicle (S112). Then, the status output unit 20 outputs the obtained driving status of the other vehicle, the surrounding road status and the driving status of the own vehicle recorded in the recording unit 14 to the negligence diagnosis server 50 (S114). In step 110, when the other party's situation acquisition unit 26 determines that the traveling situation of the other party's car cannot be acquired, the situation output unit 20 neglected the surrounding road situation and the traveling situation of the own car recorded in the recording unit 14. The data is output to the diagnostic server 50 (S116). This is the end of this flowchart.
[0031]

[0032]
FIG. 4 is a flowchart showing an operation in which the negligence diagnosis server 50 diagnoses negligence. First, the negligence diagnosis server 50 manages the negligence content in the negligence database 54 by associating the degree of negligence with the content of negligence of driving in an automobile accident (S200). The negligence diagnosing unit 52 acquires the traveling status of the automobile in which the accident has occurred from the accident status recording device 10 (S202). The negligence diagnosing unit 52 further acquires, from the accident situation recording device 10, the traveling situation of the second automobile that is the partner of the accident, in addition to the traveling situation of the first automobile in which the accident has occurred. Further, the negligence diagnosis unit 52 further acquires, from the accident situation recording device 10, the road situation around the automobile at the time of the accident, in addition to the running situation of the automobile in which the accident has occurred.
[0033]
Then, the negligence diagnosis unit 52 analyzes the acquired driving situation to determine the details of the negligence of the vehicle, and extracts the degree of negligence of the vehicle from the negligence database 54 based on the determined negligence contents. Then, the fault of the vehicle is diagnosed from the extracted fault degree (S204). The negligence diagnosing unit 52 extracts the degree of negligence stored in association with each of the plurality of negligence contents when a plurality of negligence contents are included in the driving situation of the vehicle, and based on the extracted plurality of negligence degrees. Diagnosing the negligence of the vehicle. As an example, the negligence diagnosing unit 52 diagnoses the negligence of the vehicle by adding the plurality of extracted degrees of negligence.
[0034]
The negligence diagnosing unit 52 calculates the negligence ratio of the first and second vehicles based on the running conditions of the first and second vehicles in which the accident has occurred. For example, the fault diagnosing unit 52 obtains the degree of fault of the first and second vehicles from the driving conditions of the first and second vehicles, respectively, and, based on the ratio of the determined fault, the first and second vehicles. Calculate the percentage of negligence. As an example of calculating the fault rate based on the fault rate, assuming that the fault rate of the first car is 8 and the fault rate of the second car is 12, the fault rate of the first car is 8 Calculated as /(8+12)=0.4.
[0035]
Thereby, the negligence diagnosis unit 52 determines whether the first and second vehicles are running on the basis of more detailed information including not only the running status of the first vehicle but also the running status of the second vehicle that is the partner of the accident. The fault rate can be objectively diagnosed.
[0036]
The negligence diagnosing unit 52 diagnoses negligence of the vehicle based not only on the driving conditions but also on the surrounding road conditions. For example, based on the signal switching timing, which is an example of road conditions, it is possible to determine whether or not the vehicle has been neglected for signal violation. Thereby, the negligence diagnosing unit 52 can diagnose the negligence of the vehicle based on more detailed information including not only the driving condition of the vehicle but also the surrounding road conditions.
[0037]
Finally, the negligence diagnosing unit 52 outputs the result of diagnosing the negligence of the vehicle (S206). This is the end of this flowchart.
[0038]
According to the above operation, the negligence diagnosis server 50 can objectively diagnose the negligence of the vehicle in which the accident has occurred based on the running condition of the vehicle at the time of the accident.
[0039]
The recording medium 60 stores a program that causes the negligence diagnosis system 100 to perform the operations of Steps 100 to 116 and Steps 200 to 206 described above. The negligence diagnosis system 100 reads these programs from the recording medium 60 and executes them.
