The invention relates to the technical field of power systems, and discloses a control method and device of an electric vehicle, the electric vehicle and a readable storage medium. The method comprises the following steps: acquiring a road slope signal of the electric vehicle in a driving state; judging whether the road surface gradient signal meets a ramp mode switching condition or not; and when the road surface gradient signal meets the ramp mode switching condition, the driving mode of the electric automobile is switched to the ramp driving mode. According to the technical scheme, self-adaptive switching of the ramp driving modes is achieved, recovery of large energy during ramp driving is facilitated, the speed of the electric automobile during uphill and downhill is stabilized, driving safety is improved, and meanwhile energy can be recovered as much as possible to increase the endurance mileage.

    本发明涉及动力系统技术领域,公开了一种电动汽车的控制方法、装置、电动汽车及可读存储介质。其中,该方法包括:获取电动汽车在行驶状态下的路面坡度信号;判断路面坡度信号是否满足坡道模式切换条件;当路面坡度信号满足坡道模式切换条件时,将电动汽车的行驶模式切换至坡道行驶模式。通过实施本发明技术方案,实现了坡道行驶模式的自适应切换,便于在坡道行驶时实现较大能量的回收,稳定电动汽车在上下坡时的车速,提高了行驶安全性,同时能够尽可能的能量回收实现续航里程增加。
