The present application relates to the technical field of new energy vehicles and provides a motor jitter suppression control method, system and vehicle. The method comprises: acquiring wheel speed information of a vehicle and calculating a jitter amount of a wheel speed based on the wheel speed information; acquiring motor actual torque and calculating a torque difference between the motor actual torque and motor target torque; and activating a jitter control module to perform jitter control in response to the wheel speed of the vehicle falling below a set wheel speed, an absolute value of the jitter amount exceeding a calibration threshold and the torque difference equaling zero, wherein performing the jitter control comprises: acquiring compensation torque based on the jitter amount and controlling a motor to output the compensation torque to suppress jitter of a motor speed. Accordingly, the technical solution of the present application enables the proactive execution of motor jitter control by automatically recognizing road excitations and intelligently determining the conditions for executing jitter control, thereby effectively reducing vehicle vibrations, decreasing vehicle noise levels and enhancing ride comfort.
