Abstract: A four degree of freedom vehicle mathematic model with a semi-active suspension is established and applied fuzzy control strategy to simulate the suspension system. Based on the simulation results, a fuzzy-controlled semi-active suspension with the 8098 chip microcomputer playing the main role is designed and developed, the road test for vehicle semi-active suspension is done. The simulation results approximate the road test results. It shows that the performances of semi-active suspension excel that of traditional passive suspension in the ride comfort.
