The invention specifically discloses a driving anti-slip control method for an electric vehicle, which comprises the following steps: acquiring a vehicle state signal and judging whether a creeping function flag bit is activated or not, if so, entering a creeping control mode, and if not, outputting a final torque TqOut which is equal to 0; according to a brake pedal of the vehicle, the steering angle of a steering wheel and the gradient of a road surface on which the vehicle runs, a corresponding basic torque TqBase, a crawling auxiliary torque TqClimb and a steering wheel angle correction coefficient XSteer required by crawling are obtained; according to the formula TqOut = XSteer * (TqBase + TqClimb), the final torque TqOut is obtained through calculation, and the calculated final torque TqOut is supplied to a torque executing mechanism for crawling control. According to the method, the running stability of the electric automobile in the crawling mode and the participation degree of a driver can be improved, and the adaptability to complex working conditions is enhanced.
本发明具体公开了一种电动汽车的驱动防滑控制方法,包括:获取车辆状态信号并判断是否激活爬行功能标志位,如果是,则进入蠕行控制模式,如果否,则输出最终扭矩TqOut=0;根据车辆的制动踏板、方向盘转向角及车辆行驶的路面坡度,获取爬行所需对应的基础扭矩TqBase、爬行辅助扭矩TqClimb和方向盘转角修正系数XSteer;根据公式TqOut=XSteer×(TqBase+TqClimb),计算得到最终扭矩TqOut,将计算出的最终扭矩TqOut给扭矩执行机构,以进行蠕行控制。本发明能提高电动汽车在蠕行模式下的行驶平稳性和驾驶员的参与度,增强对复杂工况的适应性。
