The invention discloses a staged active anti-shake control method and system for an electric drive system, and belongs to the technical field of automobiles. The staged active anti-shake control method comprises the steps that a motor controller reads an active anti-shake permission signal of a vehicle control unit; the motor controller reads whether the slip compensation torque of the chassis driving force controller is zero or not; the motor controller judges whether the current rotating speed fluctuation of the driving motor exceeds a set threshold value delta n or not, and then judges whether the active anti-shake function is started or not; the motor controller judges whether the current rotating speed of the driving motor is lower than the set rotating speed n1; the motor controller judges whether the current rotating speed of the driving motor is lower than a set rotating speed n2; the three-stage anti-shake function of the electric drive system is started, and the compensation torque coefficient of the electric drive system is k3 after three-stage active anti-shake is started; according to the method, the active anti-shake starting and quitting conditions of the electric drive system are defined, meanwhile, different active anti-shake control parameters are set according to the specific requirements of the vehicle for shake within different rotating speed ranges of the electric drive system, the suppression torque is properly increased when the whole vehicle is at a low speed, and the suppression torque is properly reduced when the whole vehicle is at a high speed; therefore, better driving experience can be brought to the greatest extent on the premise of ensuring the comfort of the whole vehicle.
本发明公开了一种电驱系统分级式主动防抖的控制方法及系统,属于汽车技术领域,包括:电机控制器读取整车控制器主动防抖允许信号;电机控制器读取底盘驱动力控制器打滑补偿力矩是否为零;电机控制器判断驱动电机当前转速波动是否超过设定阈值Δn,进而判断是否开启主动防抖功能;电机控制器判断驱动电机当前转速是否低于设定转速n1;电机控制器判断驱动电机当前转速是否低于设定转速n2;电驱系统开启三级防抖功能,进入三级主动防抖后电驱系统的补偿扭矩系数为k3;该方法明确了电驱系统主动防抖启动及退出的条件,同时该方法会根据电驱系统的不同转速范围内车辆对抖动具体要求设定不同的主动防抖控制参数,使整车在低速时适当增加抑制扭矩,高速时适当减少抑制扭矩,这样就可以在保证整车舒适性的前提下,尽量带来更好的驾驶体验。
