Clutch control apparatus and method

摘要

A clutch control apparatus for a power transmission system including an input rotating member (1) and an output rotating member (7,8). The clutch control apparatus includes a friction clutch (2), and a control unit (4). The control (4) unit sets a first desired clutch torque setting (T ST ) in accordance with a clutch slip indicator (e,W SL ); sets a second desired clutch torque setting (T IN ) to an amount of torque input from the input rotating member (1) to the friction clutch (2); controls the clutch torque (T CTH ) to be the first desired clutch torque setting (T ST ) during a starting stage of the friction clutch (2); controls the clutch torque (T CTH ) to be the second desired clutch torque setting (T IN ) during a steady-state stage of the friction clutch (2); and controls the clutch torque (T CTH ) to gradually change from the first desired clutch torque setting (T ST ) to the second desired clutch torque setting (T IN ) during a transition stage between the starting stage and the steady-state stage.
