Estimator designs only using relative displacement between sprung mass and unsprung mass for semi-active suspension system are investigated. Modified sensitivity method controls semi-active suspension directly using relative velocity and MR damper model without calculating absolute velocity and parameter estimator. The comfort evaluation parameters about the driver are presented and the mathematical models of skyhook and modified skyhook ontrol suspension are simulated in Simulink. The comparison results of suggests that modified skyhook control could significantly improve riding comfort and provide more comfortable working conditions for passenger, which can be widely applied on car in the future
