ADVANCED CONTROL METHODS OF ACTIVE SUSPENSION

This paper describes new control methods for the active suspension. Fo r improving ride comfort further, preview control rule is proposed. Fo r improving stability further, roll stiffness distribution control rul e is examined by the test vehicle. Simulations and vehicle driving tes ts are conducted to confirm the effect of these new control methods. T he results of simulations and vehicle driving tests show in our resear ch phase that preview control can achieve a substantial improvement in ride comfort and application Of roll stiffness distribution control p rovides a large improvement in stability.
