The invention provides a vehicle collision identification method and device, and the method comprises the steps: obtaining an acceleration signal and a piezoelectric signal of a vehicle; determining the running speed of the vehicle when the acceleration signal and the piezoelectric signal are obtained; determining a target signal in the first collision signal and the second collision signal based on the driving speed; the first collision signal is related to the acceleration signal; the second collision signal is related to the piezoelectric signal; and determining a collision recognition result of the vehicle based on the target signal. Therefore, the accuracy of the collision recognition result can be improved.

    本申请提供了一种车辆碰撞识别方法以及装置,方法包括,获取车辆的加速度信号以及压电信号;确定在获取加速度信号和压电信号时车辆的行驶速度;基于行驶速度,在第一碰撞信号以及第二碰撞信号中确定目标信号;第一碰撞信号与加速度信号相关;第二碰撞信号与压电信号相关;基于目标信号,确定车辆的碰撞识别结果。这样,可以提高碰撞识别结果的准确性。
