The embodiment of the invention provides a vehicle collision detection method and device, electronic equipment and a storage medium, and belongs to the technical field of vehicle collision.The method comprises the steps that when a rear vehicle is in a vehicle-following driving state, whether the front vehicle is in an unexpected deceleration mode or not is judged according to the change rate of the distance between the rear vehicle and the front vehicle, and if yes, the vehicle is in the unexpected deceleration mode; and if yes, performing collision prediction on the front vehicle and the rear vehicle according to the operation data of the two vehicles. And if the two vehicles have the collision risk, acquiring the running state of the front vehicle during collision to obtain the running state of the vehicle, and acquiring the speed state of the rear vehicle during collision to obtain the speed state of the vehicle. And determining the collision speed of the two vehicles according to the vehicle running state and the vehicle speed state, and performing severity grade evaluation according to the collision speed of the two vehicles to obtain severity grade evaluation data. Compared with the prior art that the severity level is subjectively judged, the accuracy is low. According to the embodiment, the severity level is determined through the collision speed of the two vehicles, and the severity level can be accurately evaluated.
本申请实施例提供了一种车辆碰撞检测方法和装置、电子设备及存储介质,属于车辆碰撞技术领域,该方法包括:后方车辆处于跟车行驶状态时,根据与前方车辆的车间距变化率判断前方车辆是否为非预期减速模式,若是,则根据二车的运行数据对前方车辆和后方车辆进行碰撞预测。若二车存在碰撞风险,则获取前方车辆碰撞时的运行状态,得到车辆运行状态,获取后方车辆碰撞时的速度状态,得到车辆速度状态。根据车辆运行状态和车辆速度状态确定二车的碰撞速度,根据二车的碰撞速度进行严重度等级评估,得到严重度等级评估数据。相比于相关技术中通过主观判断严重度等级,准确性低。本实施例通过二车的碰撞速度确定严重度等级,能够准确的评估严重度等级。
