The study focuses on the vertical, longitudinal and lateral responses of ride performance of an electric vehicle. Issues related to the design of vehicle model with passive suspension system are discussed. A full-car seven-degrees-of-freedom model is used to investigate the dynamic responses by applying road disturbances in sinusoidal road input excitation. Frequency response of the heave, roll and pitch of the sprung mass is obtained for the need of studying the effects of given variations of the suspension stiffness coefficient and the suspension damping coefficient. Finally, using the ISO-2631 criteria, the result of the responses in frequency domain are evaluated to evaluate the passenger comfortability.
