CLUTCH CONTROL SYSTEM

摘要

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 includes an electronic control unit (36) which controls 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. The control system also incorporates an automatic calibration routine which is invoked on the initial keying-on of the system, said routine comprising a predetermined sequence of events (A to U) in which the system responds to actions (B, L, P3, R3) of the operator and at predetermined points (K, N, P11, T) in the calibration routine advises the operator that the system is ready to proceed to the next stage of the calibration.
