Active Suspension System with Preview Control - A Review 2003-28-0037

The design of Automotive Suspension has been a compromise between the three conflicting parameters of road holding, load carrying and passenger comfort. For the past three decades, the introduction of increasingly sophisticated electronically controlled components into automotive suspension, redefines the boundary of the compromises.

In this paper, the first part describes the various suspension systems. The second part describes the road disturbances caused by the road followed by the need and history of preview system. It is also specified the necessary hardware required for the system along with two different preview sensor configurations. It is also explained how to generate the road surface from preview sensor. From the various literature results, it is conclude that active suspension with preview control will suit Indian road conditions.
