Abstract
A roll control system for a vehicle suspension system and a method for controlling said control system, the suspension system including support means, the roll control system including: wheel cylinders each including first and second chambers; and first and second fluid circuits, each said fluid circuit providing fluid communication between the said first chambers on one side of the vehicle and the second chambers on the opposite side of the vehicle by fluid conduits to thereby provide roll support decoupled from a warp mode of the vehicle suspension system by providing a roll stiffness about a level roll attitude whilst simultaneously providing substantially zero warp stiffness; and the method including bypassing fluid flow from at least a substantial portion of the conduits during predetermined wheel inputs to the control system to thereby minimize line damping and/or fluid inertia effects on the damping of the control system.
