Abstract

A clutch control system for the automatic control of a motor vehicle clutch (14) which connects an engine (10) with a gearbox (12) under the control of a driver-operated gear ratio selector lever (24). The control system controls both initial clutch take-up on starting of the vehicle, clutch re-engagement following each ratio change, clutch disengagement on movement of the gear selector lever to change the operative ratio of the gearbox, and clutch disengagement on the coming to rest etc of the vehicle. Additionally the clutch control system includes an anti-baulking routine which is enabled if the gear selector lever (24) is in its neutral position and which when enabled allows engagement of the clutch (14) by increasing the engine speed (Ve) above an idle level. <IMAGE>
