PURPOSE:To simplify a vehicle operation by detecting an operation of a shift/ lever and cutting liquid pressure one one side of hydraulic clutch and supplying and maintainning a half clutch pressure on the other side thereof and increasing the half clutch liquid pressure toward the connecting the half clutch liquid pressure toward the connecting direction in case of a vehicle speed reaching zero. CONSTITUTION:A shift lever operation is detected by a shift operation detector 16 and inputted to a control device 20, together with a signal of a vehicle speed detector 17. Here, the control device 20 separates an advancing clutch 5 by a solenoid valve 21 for advancing clutch control and makes a clutch of a retreating hydraulic clutch 6 by a solenoid valve 22 for retreating clutch control, when the shift/lever is changed over from advance to retreat. The liquid pressure is increased so as to place the retreating hydraulic clutch 6 in engagement in case of a vehicle speed reaching zero, and a changeover from retreat to advance is also performed. Therefore, the vehicle operation can be performed easily only by a shift lever operation. |
