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.
