Abstract
A roll control system for a motor vehicle having a vehicle body and a pair of front or rear wheel axles, the roll control system having a first fluid damper pivotally mounted on a wheel axle between the wheel axle and the vehicle body; a first fluid actuator pivotally mounted on the wheel axle between the wheel axle and the vehicle body; a second fluid damper pivotally mounted on the other wheel axle between the other wheel axle and the vehicle body; a second fluid actuator pivotally mounted on the other wheel axle between the other wheel axle and the vehicle body; wherein the first damper has a damping and stiffness compression chamber linked by a first passage to a rebound chamber in the second actuator; wherein the second damper has a damping and stiffness compression chamber linked by a second passage to a rebound chamber in the first actuator; and fluid pressure controller connecting the first passage with the second passage or isolating the first passage from the second passage and operable, during predetermined operating conditions of the vehicle, to allow an increase fluid pressure in at least one of the passages to increase roll stiffness, and to allow an increase in roll …
