The adaptation of the active control technology to practical suspension systems of vehicles has remarkably improved the safety and ride-comfort of vehicles. This paper presents a study on the practical realization methods of an active suspension system that combines high response and low energy dissipation. The effects of active control on the stability of vehicle motion and ride-comfort were investigated by practical tests using an experimental vehicle. The integrated active suspension system consists of a motor-controlled oil pump, which is active power source, and a motor-controlled variable orifice, which is semi-active adjustable element. Multi-controller computer systems for individual controls of each suspension unit and an integrated control of the whole body behavior are also installed.
