The invention relates to an automatic reversing method and system. The method comprises the following steps of recording steering, speed and position information of a vehicle in a forward process and storing the information as historical path information, after an automatic reversing function is activated, acquiring current position information and corner information of the vehicle, and planning a reversing path in combination with the historical path information, and controlling the vehicle to automatically reverse according to the planned reversing path. According to the method, the surrounding panoramic environment and real-time obstacle information are collected in the reversing process, the vehicle retreats along the original path by default, and an alternative scheme is provided to bypass obstacles and then return to the path to continue to complete reversing under the condition that the requirement for retreating along the original path cannot be met and the road is allowed; and when the user brakes the vehicle or reaches the maximum reversing distance, the vehicle stops, and the user is prompted to take over the vehicle.
本发明涉及一种自动倒车方法及系统,记录前进过程中车辆的转向、车速以及车辆的位置信息并存储为历史路径信息;自动倒车功能激活后,获取车辆的当前位置信息以及转角信息,结合所述历史路径信息,进行倒车路径规划;根据规划好的倒车路径控制车辆进行自动倒车。本发明在进行倒车过程中采集周围全景环境和实时障碍物信息,默认沿原路径后退,在无法满足原路径后退的情况下,道路允许的情况下,提供替代方案绕过障碍物,再返回路径上继续完成倒车;在用户刹停车辆,或者到达最大的倒车距离时,车辆停止,并提示用户接管车辆。
