The invention relates to an anti-shake method and an anti-shake system for an electric vehicle, the method comprises a slope-holding anti-shake method, the slope-holding anti-shake method comprises the following steps: S11, detecting whether the electric vehicle has a condition that automatic slope holding is not needed, and if the condition that automatic slope holding is not needed does not exist, entering a subsequent step S13; s13, the current gear of the electric automobile and the current steering fed back by the main driving motor are detected; s15, whether the current steering direction is opposite to the current gear or not is judged, and if the current steering direction is opposite to the current gear, the subsequent step S17 is executed; and S17, slope parking is started, the position of a main driving motor of sliding is accumulated, the main driving motor is controlled through a position closed loop, and only a proportional loop and no integral loop exist in the position closed loop. According to the anti-shake method and the anti-shake system, the shake of the electric vehicle is reduced.
本发明涉及电动汽车的防抖方法与防抖系统,该方法包括驻坡防抖方法,所述驻坡防抖方法包括如下步骤:S11、检测电动汽车是否存在不需要自动驻坡的条件,如不存在不需要自动驻坡的条件就进入后续步骤S13;S13、检测电动汽车的当前档位和主驱动电机反馈的当前转向;S15、判断所述当前转向是否与所述当前档位相反,如相反就进入后续步骤S17;S17、启动驻坡,并累计溜车的主驱动电机位置,使用位置闭环控制所述主驱动电机,所述位置闭环只有比例环没有积分环。本发明通过上述防抖方法以及防抖系统降低电动汽车的抖动。
