The invention relates to the technical field of automobile control, in particular to an electric automobile ramp assisting method and device, an electric automobile and a storage medium, and the method comprises the steps that one or more target signals in the automobile parking process are obtained; when it is judged that the vehicle meets the ramp assisting condition based on the one or more target signals, the maximum stroke of a brake pedal when the vehicle reaches the target vehicle speed in the parking process of the vehicle is obtained, and ramp assisting torque is matched according to the maximum stroke of the brake pedal; and generating a torque control instruction based on the ramp auxiliary torque, and controlling the driving motor to output the ramp auxiliary torque by using the torque control instruction to realize parking of the vehicle on the ramp. Therefore, the problems that a gradient sensor needs to be additionally arranged to achieve parking of the vehicle on a ramp, and the parking cost is high in the prior art are solved.

    本申请涉及汽车控制技术领域,特别涉及一种电动汽车坡道辅助方法、装置、电动汽车及存储介质,其中,方法包括:获取车辆停车过程中的一个或多个目标信号;基于一个或多个目标信号判定车辆满足坡道辅助条件时,获取车辆停车过程中达到目标车速时制动踏板的最大行程,并根据制动踏板的最大行程匹配坡道辅助扭矩;基于坡道辅助扭矩生成扭矩控制指令,利用扭矩控制指令控制驱动电机输出坡道辅助扭矩,实现车辆在坡道的驻车。由此,解决了相关技术需要额外增加坡度传感器实现车辆在坡道的驻车,驻车成本高等问题。
