The invention relates to the technical field of pure electric vehicles, and provides a pure electric vehicle ramp starting control method and device, a storage medium and a pure electric vehicle. The method comprises the steps that under the condition that the pure electric vehicle is on a ramp, pure electric vehicle information is obtained, whether the pure electric vehicle meets starting conditions or not is determined based on the pure electric vehicle information, and after it is determined that the pure electric vehicle meets the starting conditions, the pure electric vehicle is started. Firstly, the pure electric vehicle is controlled to enter a rotating speed control mode in a starting stage to achieve rapid starting, secondly, a preset vehicle speed is set, and when the vehicle speed of the pure electric vehicle is larger than or equal to the preset vehicle speed, the pure electric vehicle is controlled to exit the rotating speed control mode and enter a torque control mode in the starting stage. Therefore, the starting stability of the pure electric vehicle can be guaranteed on the premise that the pure electric vehicle is quickly started. The problem that in the prior art, a pure electric vehicle is slowly started on a ramp is solved, and rapid starting of the pure electric vehicle on the ramp is achieved.

    本发明纯电动车技术领域,提供一种纯电动车坡道起步控制方法、装置、存储介质和纯电动车,方法为在纯电动车处于坡道的情况下,获取纯电动车信息,基于纯电动车信息确定纯电动车是否满足起步条件,在确定纯电动车满足起步条件后,首先控制纯电动车进入起步阶段中的转速控制模式,实现快速起步,其次设定一个预设车速,当纯电动车的车速大于或等于预设车速时,控制纯电动车退出转速控制模式转而进入起步阶段中的扭矩控制模式,从而实现纯电动车在快速起步的前提下,又可以保障纯电动车起步的平稳性。解决了相关技术中,纯电动车在坡道起步慢的问题,实现纯电动车在坡道的快速起步。
