Control system for a clutch for a vehicle.

摘要

A system for controlling an electromagnetic clutch (2) for a motor vehicle at transient state of driving condition of the motor vehicle. An actual engagement rate (E) is obtained in dependence on speeds of a drive member (2a) and a driven member (2b) of the clutch (2). A desired engagement rate (Eo) of the clutch (2) is obtained in accordance with the speeds of the drive member (2a) and driven member (2b). Clutch current (1c) is controlled so as to converge the actual engagement rate (E) on the desired engagement rate (Eo). The transition of the change of the actual engagement rate (E) is observed and a correction signal is generated when the actual engagement rate (E) does not change in a converging direction. The clutch current (1c) is corrected by the correction signal.
