Abstract
In an active roll control system for a vehicle, anti-roll bars (26, 30) are provided with actuators (28, 32) which can provide a torque in the anti-roll bars to control vehicle body roll. Under certain cornering conditions when the vehicle is liable to over-steer, the pressure supply to the actuators is pulsed so that the front wheels of the vehicle tend to break away more easily, thereby reducing over-steer.
Claims18
A suspension system for connecting a wheel to a sprung part of a vehicle, the wheel being arranged to contact the ground with a contact force which controls a level of adhesion between the wheel and the ground, the system including:
- a movable part of the suspension system which can move relative to said sprung part thereby to allow vertical travel of the wheel;
- an actuator arranged to produce an actuator force between said sprung part and said movable part;
- a cornering sensor arranged to detect predetermined cornering conditions of the vehicle;
- and a controller, wherein the controller is arranged, in the event of detection of said predetermined cornering conditions, to promote lateral slipping of the wheel by producing a rapid variation in said actuator force so as to produce a pulsing of said contact force causing a reduction in said level of adhesion, so as to control the steering characteristics of the vehicle.
