Abstract
A roll control system for a vehicle is disclosed. The roll control system includes front and rear stabilizer bars, first and second magnetorheological actuators, and an electronic control system. The first magnetorheological actuator is disposed between the front stabilizer bar and the front suspension on one side of the vehicle, and a first droplink is disposed between the front stabilizer bar and the front suspension on the other side of the vehicle. The second magnetorheological actuator is disposed between the rear stabilizer bar and the rear suspension on one side of the vehicle, and a second droplink is disposed between the rear stabilizer bar and the rear suspension on the other side of the vehicle. The electronic control system is responsive to a vehicle operating characteristic and is in signal communication with the first and second magnetorheological actuators. 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.
