Here, the vehicle situation data collection system 10 does not include the camera 120 and the GPS communication unit 130, and transmits surrounding images and position information from the camera 120 and the GPS communication unit 130 provided in one vehicle, respectively. Of course you can.

At least one camera 120 is provided in one vehicle to capture a surrounding image of the vehicle.

The GPS communication unit 130 receives a GPS signal from a GPS satellite to determine the GPS coordinates of the current location.

The vehicle interface unit 110 is connected to an on-board diagnostics II (OBD-II) interface of one vehicle, receives vehicle information of one vehicle through the OBD-II interface, and transmits the vehicle information to the controller 140. Here, the vehicle information includes at least one of operation states such as speed, brake, gear, side brake, steering angle, and direction indication.

The wireless communication unit 160 wirelessly communicates with other vehicles in the vicinity of one vehicle by a communication method such as Wi-Fi, Bluetooth, or UN-Ubiquitous Sensor Network (USN).

The wireless communication unit 160 communicates with another vehicle according to the instruction of the controller 140 to receive and transmit the situation data (including at least one of vehicle information, surrounding images, and position information) of the other vehicle to the controller 140. .

The controller 140 checks the current position of the vehicle from the GPS communication unit 130 to check whether the current position of the vehicle is within a preset special area. In this case, the special area may be a road having a probability of occurrence of an accident more than a predetermined threshold. For example, the special area may be an intersection.

In this case, the controller 140 sets one or more special regions in advance according to the information from the service provider or the user's operation, and checks the change of addition or deletion of the set special regions. Reset the information by updating.

If the current location of one vehicle is outside the special area, the controller 140 stores only the vehicle information, the surrounding image, and the location information of the one vehicle in the storage unit 150 without receiving the situation data of the other vehicle.

If the current location of one vehicle is in a special region, the controller 140 receives the situation data of another vehicle through the wireless communication unit 160 and stores the situation data in the storage unit 150. In this case, the control unit 140 may request data transmission from another vehicle and receive context data of the other vehicle in response thereto. In this case, the controller 140 may also transmit situation data (including at least one of vehicle information, surrounding image, and location information of one vehicle) of one vehicle according to a request of another vehicle.

The controller 140 may classify the special area into a plurality of detailed zones in consideration of the direction in which the vehicle is traveling, and may store and store the situation data of another vehicle by the detailed zones.

For example, if the special area is an intersection where four distances meet, the control unit 140 determines the special area as a first area in which the direction of travel of the vehicle is forward from the rear of one vehicle, a second area rear from the front of the vehicle, Vehicles in other subregions are divided into four subregions, including a third region from right to left of one vehicle and a fourth region from left to right of one vehicle, and the information of the vehicles in each subregion is correlated. Can be stored separately from the information.

The controller 140 deletes situation data of another vehicle stored in the storage unit 150 when one vehicle leaves the special region without an accident. As such, the controller 140 may record necessary data in the storage 150 and delete unnecessary data therein to efficiently manage the capacity of the storage 150.

In this case, the controller 140 may determine whether an accident has occurred by using vehicle information, surrounding image and location information of one vehicle, and situation data of another vehicle. Alternatively, the controller 140 may determine whether an accident has occurred by additionally using other information such as detection information of the impact sensor.

On the other hand, since the situation data of one vehicle and the other vehicle of the storage unit 150 includes a surrounding image, a steering angle, a direction indicator, etc., an accident analyzer easily facilitates the lighting state of a special area or the location of each vehicle when the accident is analyzed. Can be inferred.

As described above, the present invention can collect accident information by a plurality of in-vehicle vehicle situation data collection system 10 located at a corresponding point at the time of an accident, synchronized to a global time using GPS or the like. In addition, by using the collected accident information complex, it supports convenient and accurate judgment of accidents, harms and damages.
