SMART SYSTEM FOR VEHICLE COMFORT MONITORING AND ACTIVE SUSPENSIONS CONTROL

Passengers' comfort is one of the most important characteristics of vehicles. Several aspects affects on it but suspension system is most important. Suspension systems demands include a high level balance between comfortable ride, excellent high speed directional stability and cornering performance. These demands are high and sometimes unattainable for passive suspension systems. Active suspension system can solve the problem by affecting on suspension characteristics according to real time measured driving conditions. In this paper, the device for control and prediction of the suspension is proposed. It is based on the “quarter car” model with the observer, designed to reconstruct the immeasurable states from the available output measurement.
