VEHICLE SPEED CONTROL SYSTEM AND METHOD
First Claim
1. A system operable to automatically control a vehicle to operate in accordance with a target speed value, the system being further operable automatically to, in dependence at least in part on a determination that a wheel of the axle is rotating faster than another wheel of the axle by more than a prescribed amount:
- apply a brake to a wheel of an axle to reduce a difference in speed between respective wheels of an axle, andsubsequently control cross-axle locking means of an axle of the vehicle to cause an increase in resistance to relative rotation of wheels of the axle while controlling the vehicle to operate in accordance with the target speed value.

Abstract
Embodiments of the present invention provide a vehicle speed control system operable to cause a vehicle to operate in accordance with a target speed value, the system being further operable automatically to control cross-axle locking means of an axle of the vehicle to cause an increase in resistance to relative rotation of wheels of the axle. Thus, the speed control system may be operable automatically to command the cross-axle locking means to increase the resistance to relative rotation of wheels of the axle without a driver being required to intervene to command assumption of this condition.

18. A method of controlling a vehicle comprising:
-
automatically causing a vehicle to operate in accordance with a target speed value; and
in dependence at least in part on a determination that a wheel of the axle is rotating faster than another wheel of the axle by more than a prescribed amount;applying a brake to a wheel of an axle to reduce a difference in speed between respective wheels of an axle, and subsequently automatically controlling cross-axle locking means of an axle of the vehicle to cause an increase in resistance to relative rotation of wheels of the axle to command the increase in resistance to relative rotation of wheels of the axle by means of the cross-axle locking means.
