Abstract
The invention provides a system (10) for a motor vehicle (100) that receives drive demand information (161S) indicative of an amount of drive demanded of a powertrain (129) of the vehicle (100), and controls an amount of drive torque applied by the powertrain (129) to one or more road wheels (111, 112, 114, 115) in dependence on the drive demand information (116S). The system also receives gradient information (11GS) relating to the driving surface and vehicle speed information (Sv). The control system, in dependence on the gradient and speed information, automatically causes a braking system (12d) to apply brake force to one or more of the wheels (111, 112, 114, 115) to prevent vehicle rollback, and adjusts the amount of brake force applied in dependence on the drive demand information (161S) to cause the amount of brake force applied to increase progressively as the amount of drive demand decreases.
