  Next, the operation of the clutch hydraulic system 60 will be described. When the clutch 62 is in the engaged state, when the rotating shaft 126 of the electric motor 68 rotates to the side where the clutch 62 is released, the worm gear 138 rotates, thereby causing the worm wheel gear 142 to rotate clockwise. At this time, since the end surface 142a of the worm wheel gear 142 pushes the projection 146a of the seesaw member 144, the seesaw member 144 also rotates together with the worm wheel gear 142, and the first roller 150 of the seesaw member 144 moves to the first master cylinder 80. One rod 94 is pushed rightward in FIG.

  As a result, the first piston 92 moves together with the first rod 94, and the hydraulic pressure in the oil chamber 124 increases. This hydraulic pressure is transmitted to the oil chamber 166 in the cylinder body 160 of the first release cylinder 72 via the first hydraulic pipe 70, and the hydraulic pressure in the oil chamber 166 increases. Accordingly, the piston 162 pushes the push rod 74, and the push rod 74 moves to the clutch 62 side.

  As a result, the clutch 62 performs the releasing operation. That is, the pressing member 186 moves away from the clutch disk 178 against the urging force of the coil spring 184, and almost no pressing force presses the clutch disk 178 and the clutch plate 180, and the clutch 62 is released.

  If the clutch lever 66 is operated when the clutch 62 is in the engaged state, the hydraulic pressure is supplied to the second communication hole 82 c via the second hydraulic pipe 76. Since this hydraulic pressure is transmitted from the second communication hole 82c to the oil chamber 82d of the second release cylinder 82, the second piston 104 and the second rod 106 move to the left in FIG. 3, and the second rod 106 is a seesaw member. The second roller 152 of 144 is pressed.

  As a result, the seesaw member 144 rotates clockwise, and the first roller 150 moves the first rod 94 of the first master cylinder 80 in the right direction in FIG. 3, so that the first piston 92 also moves and the oil chamber 124. Increases the hydraulic pressure. Accordingly, the clutch 62 is released as described above.

  When the clutch 62 is opened by the electric motor 68, when the rotating shaft 126 of the electric motor 68 rotates the clutch 62 to the engaged state side, the worm gear 138 rotates, thereby causing the worm wheel gear 142 to rotate counterclockwise. Rotate to. At this time, since the first piston 92 is urged in the left direction of FIG. 3 by the first coil spring 96, when the worm wheel gear 142 rotates counterclockwise, the urging force of the first coil spring 96 The first piston 92 and the first rod 94 move in the left direction. Accordingly, the seesaw member 144 also rotates counterclockwise.

  As a result, the hydraulic pressure in the oil chamber 124 decreases. This hydraulic pressure is transmitted to the oil chamber 166 in the cylinder body 160 of the first release cylinder 72 via the first hydraulic pipe 70, and the hydraulic pressure in the oil chamber 166 is lowered. As a result, the clutch 62 performs a fastening operation. That is, since the oil pressure in the oil chamber 166 is low, the pressing member 186 moves to the left in FIG. 4 according to the urging force of the coil spring 184, the clutch disk 178 and the clutch plate 180 are pressed, and the clutch 62 is engaged. Is done. As the pressing member 186 moves leftward in FIG. 4, the push rod 74 also moves leftward.

  Further, when the clutch 62 is released by the operation of the clutch lever 66 and the operation of the clutch lever 66 is released, the hydraulic pressure in the second communication hole 82 c is reduced via the second hydraulic pipe 76. Since this hydraulic pressure is transmitted from the second communication hole 82c to the oil chamber 82d of the second release cylinder 82, the second piston 104 and the second rod 106 move to the right in FIG. 3 by the biasing force of the second coil spring 108. . Accordingly, the pressure on the second roller 152 by the second rod 106 is released, and accordingly, the pressure on the first rod 94 by the first roller 150 is also released.

  Then, due to the biasing force of the first coil spring 96, the first piston 92 and the first rod 94 move to the left in FIG. Accordingly, the seesaw member 144 rotates counterclockwise. As a result, the hydraulic pressure in the oil chamber 166 decreases. Accordingly, the clutch 62 is released as described above.

  FIG. 5 is a configuration diagram of a driving device 200 applied to the motorcycle 10. The drive device 200 includes an electric motor 68, an operation amount sensor 78a, a motor drive unit 79a, a first hydraulic sensor 102, a second hydraulic sensor 116, and an angle sensor 143, a battery 202, an ignition switch 204 as a main switch, A relay switch 206 is provided.

  An ignition switch 204 is interposed in the first power path L1 that supplies power from the battery 202 serving as a power source to the control unit 79. A relay switch 206 is interposed in the second power path L2 for supplying power from the battery 202 to the control unit 79. The relay switch 206 includes a switch unit 206a and an operation coil 206b.

  The control unit 79 includes a diode D1, a diode D2, and a switching element 208 therein. The diode D1 and the ignition switch 204 are connected in series, and the battery 202 is connected to the anode of the diode D1 via the ignition switch 204. That is, the anode of the diode D1 is connected to the first power path L1.

  The diode D2, the switching element 208, and the switch unit 206a of the relay switch 206 are connected in series, and the battery 202 is connected to the anode of the diode D2 and the power load S through the switch unit 206a and the switching element 208 of the relay switch 206. Has been. That is, the anode of the diode D2 and the power load S are connected to the second power path L2.

  The cathodes of the diode D1 and the diode D2 are connected to the operating coil 206b of the relay switch 206. The cathode of the diode D1 and the cathode of the diode D2 are connected to each other.

  When the ignition switch 204 is turned on by the driver, electric power from the battery 202 is supplied to the operating coil 206b of the relay switch 206 via the ignition switch 204 and the diode D1. When power is supplied to the operating coil 206b, the relay switch 206 (switch unit 206a) is turned on. When the relay switch 206 is turned on, the power from the battery 202 is supplied to the power load S and the diode D2 in the control unit 79 via the relay switch 206 and the switching element 208. When power is supplied to the power load S in the control unit 79, the control unit 79 is activated. The switching element 208 is a normally-on switch that is turned off by sending a control signal to the switching element 208.

  Therefore, even when the ignition switch 204 is turned off, the power from the battery 202 is supplied to the operating coil 206b of the relay switch 206 via the relay switch 206, the switching element 208, and the diode D2. As a result, even if the ignition switch 204 is turned off, the relay switch 206 is not immediately turned off, and power is supplied to the control unit 79.

  When the ignition switch 204 is turned off, the control unit 79 determines whether the clutch 62 is engaged or disengaged based on the angle of the worm wheel gear 142 detected by the angle sensor 143 or the hydraulic pressure detected by the first hydraulic sensor 102. Determine whether.

  When determining that the clutch 62 is in the engaged state, the control unit 79 sends a control signal to the switching element 208 to turn off the switching element 208. As a result, the current flowing to the operating coil 206b is stopped, so that the relay switch 206 is turned off, and the power supply from the battery 202 to the control unit 79 is stopped.

  On the other hand, when the control unit 79 determines that the clutch 62 is in the disengaged state, the control unit 79 sends a control signal to the motor drive unit 79a to drive the electric motor 68 and cause the clutch 62 to perform a fastening operation. Then, after the clutch 62 is switched to the engaged state, the control unit 79 sends the control signal to the switching element 208 to turn off the switching element 208.

A side stand switch that is turned off when 36 is in a standing state and turned on when the side stand 36 is in a retracted state is shown. Reference numeral 216 indicates a throttle opening sensor that detects the throttle opening, and reference numeral 218 indicates an engine speed sensor that detects the rotation speed of the engine 26 (engine rotation speed).

  FIG. 6 is a state transition diagram of the clutch 62. First, when the ignition switch 204 is turned on while the ignition switch (IG switch) 204 is in an off state (state S1), a transition is made to the auto clutch parking state. The auto clutch means that the clutch 62 is automatically connected and disconnected.

  Among the parking states of the auto clutch, when the gear position (GP) is other than neutral (N) (neutral switch 212 is off) and the side stand (S / Stand) 36 is upright (side stand switch 214 is off). Transition to state S2. At this time, the clutch 62 is engaged by the electric motor 68. When the side stand 36 is retracted in the state S2 (when the side stand switch 214 is turned on), the state transitions to the state S3, and the clutch 62 is released by the electric motor 68. When the side stand 36 stands in the state S3, the state returns to the state S2, and the clutch 62 is brought into the engaged state by the electric motor 68.

  Further, in the state S3, when the gear position becomes neutral (when the neutral switch 212 is turned on), the state transitions to the state S4. At this time, the state of the clutch 62 does not change. If the gear position is other than neutral in state S4, the process returns to state S3. Further, when the side stand 36 stands in the state S4, the state transitions to the state S5. Also at this time, the state of the clutch 62 does not change. When the side stand 36 is stored in the state S5, the process returns to the state S4. Further, when the gear position is changed from the state S5 to a state other than neutral, the state transits to the state S2, and the clutch 62 is brought into the engaged state by the electric motor 68.

  When the start condition is satisfied in state S3 (throttle opening> throttle opening when fully closed, and engine speed> idle speed), the state transitions to state S6. This state S6 is a state in which the motorcycle 10 starts, and the clutch 62 is brought into a so-called half-clutch state by the electric motor 68. Thereafter, when the clutch 62 is completely engaged, the state transitions to state S7. This state S7 is a state in which the motorcycle 10 is traveling.

  When the stop condition is satisfied in the state S7 (vehicle speed ≦ predetermined speed (for example, 0 km / h)) and the gear position is set to neutral, the state transitions to the state S4. Further, in the state S7, when the stop condition is satisfied and the gear position is other than neutral, the state transits to the state S3. In the state S6, when the stop condition is satisfied and the gear position is other than neutral, the state transits to the state S3. When the stop condition is satisfied in the state S6 and the gear position is set to neutral, the state transitions to the state S4.

  When the manual condition is satisfied in state S3 (throttle opening = throttle opening when fully closed, vehicle speed = predetermined speed, and clutch lever 66 is operated), the state transitions to state S8 where the manual clutch is parked. The manual clutch means that the clutch 62 is connected / disconnected by the operation of the clutch lever 66 by the driver. At this time, the gear position is set to a state other than neutral.

  If the start condition is satisfied in the state S8, the state transitions to the state S9. This state S9 is a state in which the motorcycle 10 is starting. If the stop condition is satisfied in the state S9, the flow goes to the state S8. When the auto condition is satisfied in state S8 (throttle opening = throttle opening when fully closed, vehicle speed = predetermined speed, and no operation of clutch lever 66), state S3, which is one of the parking states of the auto clutch, Transition. Further, when the clutch 62 is completely engaged in the state S9, the state transitions to the state S7.

  When the ignition switch 204 is turned off when the auto clutch is parked or when the manual clutch is parked, the state transitions to the state S1.

  Thus, according to the above-described embodiment, even when the ignition switch 204 is turned off when the clutch 62 is in the released state, the power supply from the battery 202 to the control unit 79 is maintained, and By controlling the motor 68, the clutch 62 is engaged. Then, after the clutch 62 is switched to the engaged state, the power supply to itself is stopped. Therefore, the rotation of the rear wheel WR can be restricted when the vehicle is parked without stopping the control unit 79 while the clutch 62 is in the released state.

  A relay switch 206 is provided on the second power path L <b> 2 from the battery 202 to the control unit 79. Until the clutch 62 switches to the engaged state, the power supply to the operation coil 206b of the relay switch 206 is maintained, and then the power supply to the operation coil 206b is stopped to stop the power supply to itself. Therefore, it is possible to provide a circuit that continues to supply power to the control unit 79 even after the main switch is turned off with a simple configuration.

  When the ignition switch 204 is off and the engine 26 is stopped, if the transmission 28 is in a position other than neutral and the side stand 36 is in the standing state, the clutch 62 is engaged and the side stand 36 is retracted. In this case, the clutch 62 is released. Therefore, when the side stand 36 is in the standing state, it is in the parking state. Therefore, the clutch 62 can be engaged to restrict the rotation of the rear wheel WR when the vehicle is parked. When the side stand 36 is in the retracted state, the clutch 62 The engine can be started at any time by opening the.

  A first hydraulic pipe 70 is interposed between the electric motor 68 and the clutch 62, and a load is applied in a direction against the urging force of the coil spring 184 by the hydraulic pressure of the first hydraulic pipe 70. Perform the opening operation. Thus, the transmission system can be simplified by making the transmission system of the force between the electric motor 68 and the clutch 62 hydraulic. Even if the ignition switch 204 is turned off while the clutch 62 is in the released state, the power supply to the control unit 79 is stopped after the clutch 62 is in the engaged state, so that the hydraulic pressure is applied and left for a long time. It is easy to ensure the durability of hydraulic pressure.
