<p>PROBLEM TO BE SOLVED: To prevent an unstable clutch connection feeling and unstability of variable speed feeling resulted from fluctuation of vehicle condition. SOLUTION: In the connection/disconnection control method of a clutch by varying the fluid actuation pressure for the connection/disconnection driving of a wet friction clutch arranged in a driving power transmission system for a vehicle 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 selected out of a map and the duty is corrected (A') on the basis of a specified correction parameter (actuation fluid temperature, battery voltage, engine revolution number, etc.), at least relative to the vehicle condition and thereafter (Dst1) and the duty is output from the electronic control unit and such a specified loose duty Dk that the clutch is subsequently loosely connected, is output at every specified interval from the electronic control unit.</p> |
