Current automobile suspension systems using passive components only by utilizing spring and damping coefficient with fixed rates. The purpose of the suspension system is to improve passenger comfort while providing good road handling characteristics subject to different road profile. Passive suspensions only offer compromise between these two conflicting criteria. Active suspensions possess the ability to reduce the traditional design as a compromise between handling and comfort by directly controlling the suspensions force actuators. In this study, the active suspension system is proposed based on the Proportional Integral Derivative (PID) control technique for a quarter car model for the enhancement of its road handling and comfort. Comparison between passive and active suspensions system are performed by using road profile as an input. The performance of the active suspension system is evaluated by comparing it with passive suspension system. The performance of these will be determined by performing computer simulations using the MATLAB and SIMULINK toolbox. The simulation is enhanced with 3-D animation of car going on bump created in VRML.
