This paper presents the effect of the suspension working space, body displacement, body acceleration and wheel displacement for the non-controlled suspension system (passive system) and the controlled suspension system of a quarter car model (semi-active system), and comparison between them. The quarter car passive and semi-active suspension systems are modelled using Simulink. Proportional Integral Derivative controllers are incorporated in the design scheme of semi-active models. In the experimental work, the influence of switchable damper in a suspension system is compared with the passive and semi-active suspension systems.Keywords

To investigate the effect of active roll stabilizer system performance on vehicle stability, it is needed to study the effects of varying speeds of the on-road vehicles under different wheel steer angle on the roll angle, side slip angle and yaw rate on the vehicle stability. For a safe drive, when a vehicle is cornering it should not lose its stability on road. In this paper the response of passive and active roll stabilizer vehicle systems are simulated and compared against each other. The results of the simulation model showed a significant influence of the vehicle speed on the vehicle stability under different wheel steer angles.Keywords
