A vehicle's suspension system is the basic component which decides its dynamic performance. It is designed to separate the vehicle body and its passengers or payload from vibrations arising due to road disturbances, at the same time to ensure that the tires stay in adequate contact with the road surface. Challenges in suspension design many a time's leads in a compromise between the conflicting demands of ride comfort and road holding. Vehicles having soft suspension isolate the vehicle body from the higher frequencies in suspension but reduce the ability of the dampers to control the wheel movements which leads to poor road holding. Conversely, hard suspension provides more road holding but transmits more of the suspension movement to the body; in turn provide a less comfortable ride. The development of active/ semi active suspension has addressed both these needs and provides optimum level of ride comfort and road holding which results in the safety and driving pleasure.
