According to the vehicle collision detection method provided by the embodiment of the invention, the sensing signal parameter, the drivable area and the target obstacle information are acquired, if the sensing signal parameter is greater than or equal to the collision triggering threshold value, the vehicle body state of the vehicle is detected, and the first collision detection state is obtained; predicting the collision state of the target vehicle according to the collision probability of the target vehicle in the travelable area and the target obstacle to obtain a second collision detection state, and determining the collision state of the target vehicle based on the first collision detection state and/or the second collision detection state; according to the method, the collision state is detected through elastic wave sensing data, the problem that an existing sensor cannot detect slight collision based on slight collision signal feedback can be solved, and the collision state of the target vehicle is predicted based on the collision probability of the target vehicle in the travelable area and the collision probability of the target vehicle and the target obstacle; and the collision state of the target vehicle is determined in combination with elastic wave sensing collision detection, and an effective collision avoidance strategy is provided.

    本发明实施例中的车辆碰撞检测方法,通过获取传感信号参数、可行驶区域和目标障碍物信息,若传感信号参数大于或等于碰撞触发阈值,则对车辆的车身状态进行检测,得到第一碰撞检测状态,根据目标车辆在可行驶区域以及与目标障碍物的碰撞概率进行目标车辆碰撞状态预测,得到第二碰撞检测状态,基于第一碰撞检测状态和/或第二碰撞检测状态确定目标车辆碰撞状态;本方法利用弹性波传感数据对碰撞状态进行检测,可以基于轻微碰撞信号反馈,解决了现有传感器无法检测到轻微的碰撞发生,且基于目标车辆在可行驶区域以及与目标障碍物的碰撞概率进行目标车辆碰撞状态预测,并结合弹性波传感碰撞检测确定目标车辆碰撞状态,提供了有效的避撞策略。
