<p>PROBLEM TO BE SOLVED: To absorb response delay during connection of a clutch and accurately learn a real torque point during learning of the torque point and further, prevent a large connection shock of the clutch when controlling usual clutch connection. SOLUTION: In the connection/disconnection control method of a clutch by varying the working fluid pressure for the connection/disconnection driving of a wet friction clutch in accordance with the duty pulse output from an electronic control unit, when the clutch is connected from the disconnection condition, such a specified initial duty Dst0 that the clutch largely approaches near to the a torque point Dtb at first is output from an electronic control unit and subsequently such a specified loose contact duty Dk that the clutch comes into loose contact is output at every specified intervalΔts from the electronic control unit and further, after output of the initial duty Dst0, it is held and after a certain specified timeΔt3 longer than the above specified timeΔts, the loose contact duty Dk is output.</p> |
