Abstract

A vehicle includes: a transmission including an input shaft that receives power inputted from a power source for travel of the vehicle and an output shaft that outputs power to a drive wheel; a manual gear shifting power transmission mechanism that delivers an operation force of a driver as gear shifting power to the transmission; a clutch disposed between the power source for travel of the vehicle and the input shaft; and a controlled clutch actuation power transmission mechanism that delivers power of a clutch actuator as clutch actuation power to the clutch.

Claims (48)

1. A vehicle comprising:

a transmission comprising an input shaft that receives power inputted from power sources for travel of the vehicle and an output shaft that outputs power to a drive wheel, the power sources including an engine and an electric motor;

a gear shifting power transmission mechanism that delivers a first operation force of a driver as gear shifting power to the transmission;

a clutch disposed between the engine and the input shaft;

a controlled clutch actuation power transmission mechanism that delivers power of a clutch actuator as clutch actuation power to the clutch;

a manual clutch actuation power transmission mechanism that delivers a second operation force of the driver as clutch actuation power to the clutch, and switches a state of power transmission of the engine and the electric motor; and

a controller that controls the clutch actuator to switch the state of power transmission of the engine and the electric motor based on a mode selected by a program or the driver.

2. The vehicle according to claim 1 , wherein the clutch actuator includes a hydraulic pressure pump and an accumulator.

3. The vehicle according to claim 2 , further comprising a first on-off valve, a second on-off valve, and a third on-off valve, wherein

the manual clutch actuation power transmission mechanism includes a master cylinder to which an operation force of the driver is input, and a slave cylinder which causes the clutch to be actuated by a hydraulic pressure delivered from the master cylinder,

the controlled clutch actuation power transmission mechanism includes a hydraulic pressure passage that transmits the hydraulic pressure from the master cylinder and the accumulator to the slave cylinder,

the first on-off valve is capable of blocking a transmission of the hydraulic pressure from the master cylinder to the slave cylinder,

the second on-off valve is capable of blocking a transmission of the hydraulic pressure from the hydraulic pressure pump to the slave cylinder, and

the third on-off valve is capable of blocking a transmission of the hydraulic pressure from the accumulator to the slave cylinder.

4. The vehicle according to claim 1 , wherein the clutch actuator delivers clutch actuation power to the clutch in response to a gear shifting process of the gear shifting power transmission mechanism.

5. The vehicle according to claim 1 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the clutch actuator based on an output from the sensor and that causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.

6. The vehicle according to claim 1 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the electric motor based on an output from the sensors in such a manner as to reduce the difference in rotational speed between the input-side rotating member and the output-side rotating member.

7. The vehicle according to claim 1 , wherein in the controlled clutch actuation power transmission mechanism, an actuation signal is provided to the clutch actuator in response to an operation command given by the driver, and the clutch is actuated by action of the clutch actuator.

8. The vehicle according to claim 2 , wherein the clutch actuator delivers clutch actuation power to the clutch in response to a gear shifting process of the gear shifting power transmission mechanism.

9. The vehicle according to claim 3 , wherein the clutch actuator delivers clutch actuation power to the clutch in response to a gear shifting process of the gear shifting power transmission mechanism.

10. The vehicle according to claim 2 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the clutch actuator based on an output from the sensors and that causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.

11. The vehicle according to claim 3 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the clutch actuator based on an output from the sensors and that causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.

12. The vehicle according to claim 4 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the clutch actuator based on an output from the sensors and that causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.

13. The vehicle according to claim 8 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the clutch actuator based on an output from the sensors and that causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.

14. The vehicle according to claim 9 , further comprising:

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the engine and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the clutch actuator based on an output from the sensors and that causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.

15. A vehicle comprising:

a transmission comprising an input shaft that receives power inputted from a power source for travel of the vehicle and an output shaft that outputs power to a drive wheel;

a gear shifting power transmission mechanism that delivers a first operation force of a driver as gear shifting power to the transmission;

a clutch disposed between the power source and the input shaft;

a controlled clutch actuation power transmission mechanism that delivers power of a clutch actuator as clutch actuation power to the clutch;

a manual clutch actuation power transmission mechanism that delivers a second operation force of the driver as clutch actuation power to the clutch;

sensors that detect a difference in rotational speed between an input-side rotating member rotatable in conjunction with rotation of the power source and an output-side rotating member rotatable in conjunction with rotation of the drive wheel; and

a controller that controls the power source based on an output from the sensors in such a manner as to reduce the difference in rotational speed between the input-side rotating member and the output-side rotating member, wherein

the controller controls the clutch actuator based on an output from the sensors and causes the clutch to be actuated via the controlled clutch actuation power transmission mechanism.
