Abstract
A suspension of a vehicle is the support system between a vehicle body and wheels. The task of a suspension is to support the vehicle body and develop ride comfort. But if the attenuation force becomes large, the passenger will feel hard at high frequencies If the attenuation force becomes small, the passenger will feel soft at low frequencies. If the coefficient of spring becomes low the vehicle's naturel frequency of vibration becomes low, thus the heave, rolling and pitching will become large. In this study, a fuzzy sliding mode controller for real vehicle has been designed. A new method about fuzzy sliding mode swich hyperplane has been proposed. Experiment results are presented to confirm effectiveness of this new algorithm.
