The invention provides a downhill assisting method, device and equipment for a pure electric vehicle and a storage medium. When a downhill assisting request is received, the current running state of the vehicle is obtained in response to the downhill assisting request; then, when it is judged that the running state meets the downhill entering auxiliary condition, auxiliary braking parameters are obtained, and electric braking target torque is generated according to the auxiliary braking parameters; and finally, according to the electric braking target torque, the vehicle is controlled to run in a specified vehicle speed interval during downhill. The problem that potential safety hazards exist due to the fact that an accelerator and a brake are frequently operated when the electric automobile goes downhill for a long time is solved.

    本发明提供了一种纯电动车的下坡辅助方法、装置、设备及存储介质,在接收到下坡辅助请求时,响应于下坡辅助请求,获取车辆当前的运行状态;接着,在判断到所述运行状态符合进入下坡辅助条件时,获取辅助制动参数,并根据所述辅助制动参数生成电制动目标转矩;最后,根据所述电制动目标转矩控制车辆在下坡时以指定车速区间行驶。解决了在电动汽车进行长下坡时频繁的操作油门和刹车存在安全隐患的问题。
