Abstract
A clutch control apparatus includes a clutch disk, which is engaged with a flywheel, by means of a diaphragm spring; a release mechanism (including a rod and an electric motor) for pressing a central portion of the diaphragm spring; and a clutch control circuit. The clutch control circuit calculates an ideal clutch load and an output torque of the electric motor for a detected stroke of the rod. On the basis of these values, the clutch control circuit obtains the acceleration of the rod. The clutch control circuit estimates a stroke of the rod from the obtained acceleration and causes an adjust wedge member to rotate such that a detected actual stroke and the estimated stroke become equal, thereby modifying the attitude of the diaphragm spring accordingly.
