Abstract
A clutch control system for a motor vehicle having an engine (10), a gearbox (12) having a plurality of gear ratios, and a clutch (14) providing a drive connection between the engine and the gearbox. The control system includes a clutch actuation means (22) for controlling the state of engagement of the clutch and a control unit (36) which receives signals from a plurality of vehicle operating parameter sensors including a gear sensor (32) which indicates that a gear ratio is engaged in the gearbox. The control unit (36) processes these signals to produce a command signal for operation of the clutch actuating means. The control unit (36) ensures that if on powering-up of the control unit (36) the control unit receives a signal from the gear sensor (32) indicating that a gear ratio is engaged in the gearbox (12), the control unit inhibits disengagement of the clutch (14) by the clutch actuation means (22).
