ABSTRACT:
The invention relates to a method for calculating a modification to the predetermined amount of torque needed to provide an urge to move sensation for a vehicle, the modification to take account of the weight at which and gradient on which the vehicle is operating and then commanding the engine to generate said modified torque and to transmit the modified urge torque to a clutch device to provide the urge to move according to the current operating conditions.
