The invention provides a backing-up control method and device and an electric automobile, and relates to the technical field of electric automobile control. According to the backing-up control method, under the backing-up working condition, when it is judged that the current rear obstacle distance of an automobile and the automobile speed meet the starting condition of an auxiliary backing-up function, the auxiliary backing-up function is started; under the condition that the auxiliary reversing function is started, according to at least one of the rear obstacle distance, the vehicle speed and the current accelerator pedal opening degree of the vehicle, target output torque used for controlling the vehicle speed to be reduced is determined; and controlling reversing according to the target output torque. According to the scheme, the vehicle speed can be controlled to be reduced in the reversing process, and vehicle collision is avoided.
本发明提供了一种倒车控制方法、装置及电动汽车,涉及电动汽车控制技术领域,所述倒车控制方法通过在倒车工况下,判断车辆当前的后方障碍物距离与车速满足辅助倒车功能的开启条件时,开启所述辅助倒车功能;在所述辅助倒车功能开启的情况下,根据所述后方障碍物距离、所述车速以及车辆当前的加速踏板开度中的至少一项,确定用于控制车速降低的目标输出扭矩;根据所述目标输出扭矩控制倒车。本发明的方案可以控制倒车过程中车速降低,避免发生车辆碰撞。
