The invention provides a motor torque zero-crossing control method and a related device, and relates to the technical field of vehicle control. The method comprises the steps of determining a target rotating speed according to a current rotating speed of a driven gear under the condition that a motor demand torque is detected to be in a target torque zero-crossing interval; before the meshing surfaces of the driven gear and the driving gear are completely attached again, the current rotating speed of the driving gear is adjusted to the target rotating speed; wherein in the process of adjusting the current rotating speed of the driving gear to the target rotating speed, a torque compensation value is determined based on the difference between the actual rotating speed of the driving gear and the intermediate target rotating speed, so that the torque of the motor is adjusted, and the rotating speed of the driving gear is controlled. According to the technical scheme, the problem that in the prior art, when the torque zero-crossing working condition occurs to the motor, a vehicle shakes can be solved.
