In this paper we discuss the development of estimation and control algorithms for the in-vehicle implementation of the Rotary Magneto -Rheological damper. Specifically, we address the estimation of sprung mass heave rate based on suspension position sensor measurements, the design of roll angle control based on lateral load transfer distribution concept, and the integration of these two with the wheel hop detection and control algorithms. The resulting integrated ride and roll controller is evaluated based on both vehicle dynamic response and ride quality objective criteria.
