A clutch control method for controlling the disconnection/connection of a clutch by altering the working fluid pressure for driving the disconnection/connection of a wet friction clutch (3) in accordance with the duty pulse output from the electronic control unit, wherein, when said clutch is connected from the disconnected state thereof, a start duty (Dst0) is first output from the electronic control unit (16), said start duty (Dst0) being predetermined such that the clutch is connected broadly up to a point close to the torque point and the generation of excess clutch connection shock is constantly avoided in consideration of variances of the torque point; a first gradual connection duty is then output from the electronic control unit in prescribed intervals so as to gradually connect the clutch; and a second gradual duty is output from the electronic control unit (16) in prescribed time intervals such that the clutch is gradually connected slowly from the time a prescribed condition is satisfied.
