In the on-board electrical system,DC motor system driven by PWM is a stable source of disturbance.There are many crosstalk problems caused by DC motor harness crosstalk,the reason is that the ringing generated in the motor is crosstalk to the sensitive circuit through the harness distribution parameters.By analyzing the parasitic parameters and filtering parameters of the motor,this paper studies and establishes the equivalent model of the harness crosstalk simulation disturbance source of the motor,and studies the ringing control method of the motor system,finally,the accuracy of the model is verified by comparing the simulation data with the actual data.
