Taking the independent four motorized wheels driving electric vehicle (4WD EV) as study object, the method and index evaluating ride comfort of automobile suspension system were described, and the input model of random road excitation and the dynamics model of 1/4 vehicle vibration system were established, then the simulation of ride comfort of the established model was conducted, so the evaluating indexes’ responses in time domain and frequency domain were obtained. Above all, the changes of these indexes which are suspension damping, spring stiffness and un-sprung mass were analyzed, their effects on the ride comfort of electric vehicle driven by motorized wheel studied, thus provided reference for the development of electric vehicle driven by in-wheel motor.
