<p>PURPOSE:To relieve a shock on disconnecting a clutch by making disconnecting control of said clutch based on relationship between the rotation of an input shaft and the opening of a throttle valve. CONSTITUTION:A control unit9 detects the engaging condition of a clutch through a potentiometer 3 while controls a flow requlator valve 10, a pressure feed valve 11, and a pressure discharge valve 12. And, it checks whether an idle switch which detects that a foot is off from an accelerator pedal, is on and, if the car speed is less than a set speed when this switch is on, detects the rotation Ni of an input shaft and the opening TH of a throttle valve. Then, it determines the optimum opening THi of the throttle valve for disconnecting the clutch with respect to the detected rotation of the input shaft, compares the opening TH with the THi and, when TH<=THi, it makes disconnecting control of the clutch.</p> |
