The invention relates to a vehicle collision detection method and device. The method comprises the following steps: acquiring audio information in a driving process of a target vehicle in real time; analyzing and processing the audio information to obtain sound feature information of the audio information; acquiring current state information and driving environment information of the target vehicle; according to the sound feature information, the current state information and the driving environment information, judging whether the target vehicle collides or not; when the target vehicle collides, generating collision event information according to the sound feature information; and sending the collision event information to an automatic driving module, so that the automatic driving module adjusts an automatic driving decision of the target vehicle according to the collision event information. According to the invention, the audio information collected by the sound sensor arranged on a frame, the state information of the vehicle and the environment information are combined for analysis, so that the slight collision between the vehicle and a close-distance obstacle can be accurately detected.

    本发明涉及一种车辆碰撞检测方法及装置,所述方法包括:实时采集目标车辆行驶过程中的音频信息;对所述音频信息进行分析处理,得到所述音频信息的声音特征信息;获取所述目标车辆的当前状态信息和行驶环境信息;根据所述声音特征信息、所述当前状态信息和所述行驶环境信息判断所述目标车辆是否发生碰撞;当所述目标车辆发生碰撞时,根据所述声音特征信息生成碰撞事件信息;将所述碰撞事件信息发送至自动驾驶模块,以使得所述自动驾驶模块根据所述碰撞事件信息调整所述目标车辆的自动驾驶决策。本发明通过结合设置于车架上的声音传感器采集的音频信息、车辆的状态信息和环境信息进行分析,能够准确地检测车辆与近距离障碍物发生的轻微碰撞。
