ABSTRACT:
A clutch control apparatus for a power transmission system including an input rotating member and an output rotating member. The clutch control apparatus includes a friction clutch, and a control unit. The control unit sets a first desired clutch torque setting in accordance with a clutch slip indicator; sets a second desired clutch torque setting to an amount of torque input from the input rotating member to the friction clutch; controls the clutch torque to be the first desired clutch torque setting during a starting stage of the friction clutch; controls the clutch torque to be the second desired clutch torque setting during a steady-state stage of the friction clutch; and controls the clutch torque to gradually change from the first desired clutch torque setting to the second desired clutch torque setting during a transition stage between the starting stage and the steady-state stage.
