Abstract

An advanced suspension system with adjustable fuzzy control algorithm is designed to improve vehicle comfort and road holding capability. It not only can reflect the advantage of fuzzy logic in nonlinearity system but also can improve the disadvantage of common fuzzy control method strongly depending on the experience. In this paper, taking the ride comfort and road handing as system control objective, the system control mechanism is discussed. For two degree-of-freedom vehicle model, the simulation of vehicle performance under road signal is studied, its results show the advanced suspension system can effectively control the vibration of vehicle system, especially the acceleration of the sprung mass.
