The invention relates to an electric vehicle motor anti-shake control method and device and a storage medium. The control method comprises the steps that the first motor rotating speed and the whole vehicle speed are obtained through a whole vehicle controller; acquiring the rotating speed of a second motor through a motor controller; performing first-order low-pass filtering processing on the difference value of the rotating speed to obtain a rotating speed difference filtering value, and performing differential processing on the rotating speed difference filtering value to obtain an original control signal reflecting an impact oscillation jitter component of the gap region; an anti-shake control addition parameter and an anti-shake control multiplication parameter are obtained through the vehicle speed and the rotating speed difference filtering value of the whole vehicle, the original control signal is corrected according to the anti-shake control addition parameter and the anti-shake control multiplication parameter, and an anti-shake compensation torque value is obtained; and superposing the anti-shake torque compensation torque value to the required torque of the vehicle control unit to obtain an execution torque signal of the motor system. The torque in the opposite direction can be output according to the size of the jitter component, the jitter torque is offset, the driving smoothness is improved, and jitter is restrained.

    本发明涉及一种电动汽车电机防抖的控制方法、装置及存储介质,其控制方法包括:通过整车控制器获取第一电机转速和整车车速;通过电机控制器获取第二电机转速;对转速的差值进行一阶低通滤波处理得到转速差滤波值,对转速差滤波值进行微分处理,得到反映了间隙区域的冲击振荡抖动分量的原始控制信号;通过整车车速和转速差滤波值获取防抖控制加法参数和防抖控制乘法参数,根据防抖控制加法参数和防抖控制乘法参数对原始控制信号进行修正,得到防抖补偿扭矩值;将防抖扭矩补偿扭矩值叠加到整车控制器的需求扭矩上,得到电机系统的执行扭矩信号。本发明能根据抖动分量的大小来输出相反方向的扭矩,抵消抖动扭矩,增加驾驶的平顺性,抑制抖动。
