Vehicle suspension system plays a crucial role to ensure vehicle stability and ride comfort. A suspension system controls the vehicle body from excessive rolling and pitching while reduce the effect of shock forces from the road. Soft suspension system promotes good ride comfort while stiffer suspension promotes better car handling. Both comfort and good handling can be achieved by a variable suspension system. In the existing adjustable suspension unit, driver needs to stop the car, pop-up the hood and turn the selector knob manually to select the desired stiffness. By implementing a servo motor to replace the knob, the system now become an electronically – variable automotive suspension system that use motorized mechanism to control the suspension stiffness. With this system the driver can select suspension setting from inside the car while driving using touchscreen GUI. The system can have either selectable fixed-stiffness settings (fixed mode) or be made to respond to dynamic inputs - such as lateral G-force or vehicle speed – (adaptive mode), to become a semi-active suspension system.
