Development of an Active Suspension System for Passenger Cars( I ) : Construction of Prototype Car

승용차용 능동제어식 현가시스템의 개발(1) : 실험차량의 구성

Low-band type active suspension system is implemented on a passenger car. Level. roll, pitch and bouncing motion of body are controlled by a digital controller. Sky-hook damper is applied to control bouncing motion. This paper describes overall construction of the system, design of hydraulic system, sensor system, controller, and control scheme. Performance of prototype car has been evaluated on a test track and reported in the second paper.
