Abstract

When the passenger vehicle runs on an off-road, the vertical displacement occurs. This vertical displacement variation affects settling time and some oscillations for passengers on the vehicle. The passenger vehicle is simulated with a quarter car system. We measure the vertical peak displacement and settling time using the quarter simulation model using the road profile with semicircular bump stop. The active suspension system with specific feedback control has better performances for the settling time and the peak value of the transient response than the passive suspension system has.
