Abstract

A control apparatus for an automotive clutch sets engine rotational speeds set for respective gear positions for disengaging the clutch, and disengages the clutch when the engine rotational speed drops below the set engine rotational speed corresponding to a present gear position at the time a braking force is higher than a preset value upon actuation of a brake. The control apparatus determines a rate of reduction of the engine rotational speed when the brake is actuated, and disengages the clutch when an integrated value of the rate of reduction of the engine rotational speed corresponds to one of preset values set for the respective gear positions.
