The embodiment of the disclosure discloses a vehicle jitter control method and device, a drive control system and a vehicle, relates to the technical field of vehicle control, and mainly aims to improve the effect of suppressing vehicle jitter. According to the main technical scheme, the method comprises the steps: filtering out the disturbance variable of a torque command in a first frequency band to obtain feedforward compensation torque; extracting a rotating speed jitter amount in a second frequency band in the current rotating speed of the driving motor through a low-pass filter and a high-pass filter, the rotating speed jitter amount being in phase synchronization with the current rotating speed; determining a feedback compensation torque based on the rotation speed jitter amount; and correcting the feedforward compensation torque by utilizing the feedback compensation torque, and controlling the driving motor to output the corrected feedforward compensation torque.

    本公开的实施例公开了一种车辆抖动控制方法及装置、驱动控制系统、车辆,涉及车辆控制技术领域,主要目的在于提高抑制车辆抖动的效果。本公开的实施例的主要技术方案包括:滤除扭矩命令在第一频率段内的干扰量,得到前馈补偿扭矩;通过低通滤波器和高通滤波器提取驱动电机的当前转速中位于第二频率段中的转速抖动量,其中,所述转速抖动量与所述当前转速相位同步;基于所述转速抖动量,确定反馈补偿扭矩;利用所述反馈补偿扭矩修正所述前馈补偿扭矩,并控制所述驱动电机输出修正后的前馈补偿扭矩。
