Patent ID: 7275750

Claim:
A roll control system for a vehicle having a front suspension and a rear suspension, the roll control system comprising: a front stabilizer bar; a rear stabilizer bar; a first magnetorheological actuator disposed between the front stabilizer bar and a support portion of the front suspension on one side of the vehicle, and a first droplink disposed between the front stabilizer bar and the front suspension on the other side of the vehicle; a second magnetorheological actuator disposed between the rear stabilizer bar and a support portion of the rear suspension on one side of the vehicle, and a second droplink disposed between the rear stabilizer bar and the rear suspension on the other side of the vehicle; and an electronic control system responsive to a vehicle operating characteristic and in signal communication with the first and second magnetorheological actuators; wherein the first and second actuators are responsive to a control signal from the electronic control system such that they are locked in response to the vehicle undergoing a cornering maneuver, and are unlocked in response to the vehicle not undergoing a cornering maneuver; and wherein in response to either of the first and second magnetorheological actuators being locked, an end of the respective stabilizer bar connected thereto is restrained from translational movement in a direction defined by an axis of the respective magnetorheological actuator.
