Improve control and ride comfort in a suspension system is achieved by controlling the state variables for reducing the influence of road input displacement. Study of ride performance of 7- DOF car model and validation is the aim of paper. Passive and active car model is fabricated to reduce roll over effect and enhance ride ease. In MATLAB Simulink software, simulation model is established. Using automobile dynamics software the car model is authenticated. The simulation results are validated by Simulink. Fuzzy logic concepts are introduced to develop active suspension method. Body acceleration, tyre distance and working space is considered as input variables. Utility of inputs is resulting from the control signal. Results show noteworthy enhancement over active suspension system as compare to passive suspension system.
