The invention provides rear-end collision auxiliary control equipment, a vehicle, a rear-end collision auxiliary control method and a storage medium, and belongs to the technical field of vehicle control. The rear-end collision auxiliary control device comprises a laser radar module, a system controller and a microcontroller. When the vehicle is in a parking state, the system controller controls the laser radar module to operate; the relative speed of a rear vehicle closest to the tail of the vehicle and the relative distance between the rear vehicle and the tail of the vehicle are detected through a laser radar module; then, the microcontroller judges whether the rear-end collision risk exists between the rear vehicle and the vehicle or not according to the relative vehicle speed and the relative distance; when it is determined that the risk of rear-end collision exists, the microcontroller controls the steering wheel of the vehicle to rotate in the target direction so that the steering angle of the vehicle can exceed the specified angle, and therefore after the vehicle is subjected to rear-end collision, the vehicle can be made to steer to slide laterally based on the collision force, the vehicle is prevented from colliding with an obstacle in front of the vehicle after being subjected to rear-end collision, and the safety of the vehicle is improved. And the safety of the vehicle during rear-end collision can be improved.
本申请提供一种追尾辅助控制设备、车辆、追尾辅助控制方法及存储介质,属于车辆控制技术领域。追尾辅助控制设备包括激光雷达模块、系统控制器及微控制器。在本车处于驻车状态时,系统控制器控制激光雷达模块运行;通过激光雷达模块检测距离本车尾部最近的后方车辆的相对车速及后方车辆与本车尾部的相对距离;然后,微控制器根据相对车速及相对距离,判断后方车辆与本车是否存在追尾风险;当确定存在追尾风险时,微控制器控制本车的方向盘以目标方向转动,以使本车的转向角度超过指定角度,如此,当本车被追尾后,可以基于碰撞的力让本车转向侧方滑行,避免本车被追尾后又撞向本车前方的障碍物,有利于提高被追尾时本车的安全性。
