Abstract
A system for providing vehicle roll control that controls the friction-force of dampers provided at the wheels of the vehicle. The system includes a lateral acceleration sensor for determining the lateral acceleration of the vehicle, a steering angle sensor for determining the steering angle of the vehicle and a speed sensor for determining the speed of the vehicle. The system calculates a current control signal for one or more of the dampers based on the lateral acceleration and/or the steering angle, and uses one or both of the current control signals to control the friction-force of the inside, outside or both of the dampers.
