The invention relates to the technical field of motors, in particular to a vehicle motor torque ripple suppression method and device.The method comprises the steps that the current torque, the current rotating speed and the current electrical angle of at least one motor of a vehicle are obtained, a relation table of the torque, the rotating speed and the electrical angle and iq compensation values is inquired, and a target iq compensation value for suppressing torque ripple is obtained, wherein the relation table is calculated by a pre-trained neural network model, and the output of the at least one motor is controlled according to the target iq compensation value, so that the actual rotating speed output by the at least one motor is consistent with the target rotating speed. According to the embodiment of the invention, the iq compensation value relation table of the vehicle motor can be obtained based on the neural network model, and the relation table is inquired according to the current torque, the current rotating speed and the current electrical angle so as to obtain the iq compensation value capable of suppressing the torque ripple, so that comprehensive suppression of the torque ripple is realized, the suppression precision of the vehicle motor to the torque ripple is improved, and the suppression efficiency of the vehicle motor is improved. And stability and practicability are realized.
