A suspension control system possesses the ability to reduce acceleration of sprung mass continuously as well as to minimize suspension deflection, which results in improvement of tire grip with the road surface, thus, break control and vehicle manoeuvrability can be improved. The major purpose of the suspension system is to provide a smooth ride in the vehicle and to help maintain control of the vehicle over rough terrain or in case of sudden stops, increasing ride comfort results in larger suspension stroke and smaller damping in the wheel hop mode.
