A time domain analysis method of ride comfort and energy dissipation characteristics is proposed for automotive vibration PID control. A two degree of freedom single wheel model for automotive vibration control is established, and the conventional vibration response variables for ride comfort evaluation and the energy consumption vibration response variables for energy dissipation characteristics evaluation are determined. The PID control parameters were tuned using the differential evolution algorithm, and to improve the algorithm's adaptive ability, an adaptive operator was introduced in this article, so that the mutation factor of the differential evolution algorithm can change with the number of iterations. Based on PID control and its parameter tuning, a time-domain solution method for two types of vibration response varaibles, their root mean square values and the average power of energy consumption vibration of automotive vibration PID control is proposed.
