Embodiment 1

[0086] see figure 1 , which is a flow chart of a vehicle accident recording method provided in an embodiment of the present application. The method described in this embodiment is applied to the OBU of the own vehicle, where the own vehicle is in a stationary state. As a scenario example, when the self-driving car is parked on the side of the road in unmanned driving mode, or when the self-car is parked at the corresponding position at the intersection according to the signal lights, the self-car is in a static state. This embodiment does not limit the specific static scene of the ego vehicle.

[0087] like figure 1 As shown, the vehicle accident recording method provided in this embodiment includes:

[0088] Step 101: The on-board unit OBU obtains the position of the own vehicle and the basic safety message BSM broadcast by other vehicles.

[0089] On-board unit OBU, also known as: mobile on-board unit, is usually installed on a vehicle. In order to facilitate the unders...

Embodiment 2

[0117] see image 3 , which is a flow chart of another vehicle accident recording method provided in this embodiment.

[0118] like image 3 As shown, the vehicle accident recording method provided in this embodiment includes:

[0119] Step 301: wake up when receiving a wake-up signal from a sensor located in the own vehicle.

[0120] Step 302: Obtain the location of the own vehicle and the basic safety message BSM broadcast by other vehicles.

[0121] The implementation manner of steps 301-302 in this embodiment is the same as the implementation manner of steps 100-101 in the foregoing embodiments, so the relevant description of steps 301-302 may refer to the foregoing embodiments, and details are not repeated here.

Abstract

The application discloses a vehicle accident recording method and device and a vehicle. A vehicle-mounted unit OBU acquires the own vehicle location and basic safety message (BSM) broadcasted by othervehicles in a vehicle stationary state, wherein the BSM includes identification codes and historical paths of the other vehicles; the OBU determines a suspected vehicle based on a relative position relationship between the own vehicle position and the historical paths of the other vehicles and generates a vehicle accident record including the suspected vehicle identification code; and when collision or scratch occurs between another vehicle and the vehicle in the stationary state, the vehicle is close to the another vehicle at the accident time and thus whether the another vehicle is a suspected vehicle causing the accident can be determined based on a relative position relationship between the own vehicle position and the historical paths in the BSM. After determination of the suspectedvehicle, the OBU generates a vehicle accident record containing the suspected vehicle identification code, thereby tracking the suspected vehicle and fixing the duty. Because of free of the limitationof the recording direction, the success rate of recording suspected vehicles is increased substantially and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a vehicle accident recording method, device and vehicle. Background technique [0002] With the continuous improvement of people's living standards, the number of cars is gradually increasing, and frequent vehicle accidents have attracted widespread attention. Among many types of vehicle accidents, collision or scratching when the vehicle is stationary is a relatively common type of vehicle accident. In such vehicle accidents, it is often difficult to determine responsibility because the owner of the vehicle was not at the scene of the accident and the perpetrator escaped. For this situation, one possibility is that the car owner spends a lot of time and energy to retrieve surveillance video to find the perpetrator, and the perpetrator will compensate after the accident is determined; the other possibility is that the vehicle is not in the monitoring area, and the car...
