The embodiment of the invention provides a collision detection method and device, a vehicle and a storage medium, and relates to the technical field of vehicles. In the automatic parking process, the target vehicle speed and the real-time acceleration after the real-time vehicle speed of a vehicle is delayed are obtained, and the delay duration of the real-time vehicle speed is determined according to the waveform change period of the real-time acceleration; an acceleration maximum threshold value corresponding to the target vehicle speed is obtained, and the target vehicle speed and the acceleration maximum threshold value have a preset mapping relation; if the real-time acceleration is larger than or equal to the acceleration maximum threshold value, it is determined that the vehicle collides with an obstacle at the tail end of the parking space, the obstacle at the tail end of the parking space is used for blocking wheels to limit the reversing position of the vehicle, and the omission ratio of detecting whether the vehicle collides with the obstacle at the tail end of the parking space or not can be reduced.
本申请实施例提供一种碰撞检测方法和装置、车辆、存储介质,涉及车辆技术领域。通过在自动泊车过程中,获取车辆的实时车速延时后的目标车速、实时加速度,其中,实时车速延时的时长根据实时加速度的波形变化周期确定;获取与目标车速对应的加速度最大值阈值,其中,目标车速和加速度最大值阈值具有预先设定的映射关系;若实时加速度大于或等于加速度最大值阈值,确定车辆碰撞到车位末端的障碍物,车位末端的障碍物用于挡住车轮以限制车辆的倒车位置,可以降低检测车辆是否碰撞到车位末端的障碍物的漏检率。
