Abstract
A control system for a vehicle controls the distribution of drive torque to its road wheels. The system increases a degree of locking of a differential in response to a detected increase in road roughness. Thus a difference in drive torque supplied to different wheels is reduced. The system is typically applied to a four wheel drive vehicle comprising centre and rear differentials. A controller 28 receives signals from sensors, such as ride height sensors 42,44,46,48 and wheel speed sensors 34,35,38,40. The controller 28 determines from the ride height signals and wheel speed signals the degree of roughness of the surface over which the vehicle is travelling. The degree of locking is increased with increased road roughness to avoid loss of traction.
