The invention relates to an anti-slip control method and device for an electric vehicle and the electric vehicle, and the method comprises the steps: obtaining the equivalent ramp resistance of the electric vehicle; the equivalent ramp resistance is determined and obtained by combining the vehicle load capacity with a fixed numerical value and driving related parameters of the electric vehicle; the current working condition of the electric vehicle and the current whole vehicle request torque are obtained; the current working condition comprises a motor automatic parking working condition and a non-motor automatic parking working condition; according to the current working condition, the current whole vehicle request torque and the equivalent ramp resistance, the target torque of the electric vehicle is determined; and motor driving control processing is carried out on the electric vehicle according to the target torque, so that the actual load capacity and gradient information of the electric vehicle are prevented from being adopted in the target torque calculation process, the practicability is high, slope parking can be achieved through the determined target torque, the slope sliding phenomenon is effectively prevented, and the slope sliding prevention control efficiency is improved.

    本公开关于一种电动车辆的防溜坡控制方法、装置及电动车辆,其中,该方法包括:获取电动车辆的等效坡道阻力;等效坡道阻力,结合固定数值的车辆载重量,以及电动车辆的行驶相关参数确定得到;获取电动车辆的当前工况以及当前整车请求扭矩;当前工况包括电机自动驻车工况和非电机自动驻车工况;根据当前工况、当前整车请求扭矩以及等效坡道阻力,确定电动车辆的目标扭矩;根据目标扭矩对电动车辆进行电机驱动控制处理,从而避免在目标扭矩计算过程中采用电动车辆的实际载重量以及坡度信息,实用性强,且确定得到的目标扭矩能够实现驻坡且有效防止溜坡现象,提高防溜坡控制效率。
