Abstract Vehicle active suspension system ensures the better travelling comfort for the passenger in the automotive industry. In this paper, FLC is proposed to reduce vibration of Full Car Model (FCM) with seven Degrees of freedom. FLC is developed to minimise the Body Acceleration(BA) at each wheel of FCM. In order to validate the performance of the proposed controller, the time responses of FCM with FLC is compared with Proportional Integral Derivative (PID) controller and Passive Suspension System (PSS). Two kinds of road profile such as bump and random input are considered as the road disturbances. The simulation results demonstrate that root mean square values of BA are significantly reduced in FLC when compared to PID and PSS.
