Abstract
Abstract This paper summarizes results from a recent program of tire-vehicle system research, using simulation techniques to identify the influence of tire characteristics on the vehicle response functions of yaw rate and lateral acceleration. Tire characteristics such as cornering stiffness, cornering stiffness-wheel load dependency, self-aligning torque, and dynamic tire behavior were varied with respect to a control tire. Computer simulations of vehicles undergoing a steering wheel pulse input were carried out using ADAMS full vehicle models and the Magic Formula tire model. Frequency responses were obtained from these vehicle handling simulations. The Four Parameter Evaluation Method of Lateral Transient Response was used to judge the vehicle handling performance. The influences of tire characteristic properties on the vehicle lateral transient response are explained by this method.
