Abstract :
In this paper, the riding comfort and handling safety of vehicle are regarded as control aims. An adjustable fuzzy control algorithm which fuzzy control rule table can be obtained with the numerical calculation is advanced. Because the algorithm can adjust the rectification factor of fuzzy controller, 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. For two degree-of-freedom (DOF) vehicle model, the simulation of vehicle performance in road signal is studied, its results show the adjustable fuzzy algorithm can effectively control the vibration of vehicle system
