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.
