Abstract
Large vehicle as a construction vehicle is bounced because of running rough road. This vibration bounces the cabin and transmits the driver. The driver gets tired and his efficiency of work grows worse. This paper examines improving a ride quality and reducing a ride quality aggravation affected a load variation by vibration control system with an active seat suspension. The controller was designed by applying the H-infinity control theory. The numerical simulation results show that the ride quality for driver improved by the active seat suspension.
