Abstract

A vehicle includes a transmission shiftable by hydraulic pressure, a main oil passage that delivers operating oil, a first oil passage that delivers the operating oil from the main oil passage to the transmission, a first valve that opens/closes the first oil passage, a controller that controls the first valve, a second oil passage that delivers the operating oil from the main oil passage to the transmission, and a manually drivable second valve that opens/closes a section of the first oil passage that is closer to the main oil passage than the first valve and the second oil passage. The second valve is switchable between the automatic control state in which the first oil passage is opened and the second oil passage is closed and the manual control state in which the first oil passage is closed and the second oil passage is opened.

Claims (44)

1. A vehicle comprising:

a transmission that is shiftable by hydraulic pressure;

a main oil passage configured to deliver operating oil;

a first oil passage configured to deliver the operating oil from the main oil passage to the transmission;

a first valve configured to open and close the first oil passage;

a controller configured to control the first valve,

a second oil passage configured to deliver operating oil from the main oil passage to the transmission; and

a second valve manually drivable and configured to open and close a section of the first oil passage and the second oil passage, and switchable at least between an automatic control state and a manual control state, the section being closer to the main oil passage than the first valve, the automatic control state is being a state in which the first oil passage is opened and the second oil passage is closed, and the manual control state being a state in which the first oil passage is closed and the second oil passage is opened.

2. The vehicle according to claim 1 ,

wherein the first oil passage comprises a pre-branching oil passage that is located closer to the main oil passage than the first valve, a first forward communication path that is located closer to the transmission than the first valve and is in communication with a forward clutch of the transmission, and a first reverse communication path that is located closer to the transmission than the first valve and is in communication with a reverse clutch of the transmission;

wherein the second oil passage comprises a second forward communication path that is in communication with the first forward communication path and a second reverse communication path that is in communication with the first reverse communication path; and

wherein, in the manual control state, the second valve is configured to open one of the second forward communication path and the second reverse communication path and close the other.

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

a third valve that is provided on the first oil passage so as to be located closer to the transmission than the first valve and is configured to open the first oil passage when the second valve is in the automatic control state and is configured to close the first oil passage when the second valve in the manual control state.

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

5. The vehicle according to claim 3 ,

wherein the third valve is manually drivable in conjunction with the second valve.

6. The vehicle according to claim 4 ,

wherein the third valve is manually drivable in conjunction with the second valve.

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

a second relief oil passage through which, when the second valve closes the second oil passage, operating oil in the second oil passage, the operating oil being located closer to the transmission than the second valve, is configured to be discharged.

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

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

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

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

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

13. The vehicle according to claim 1 , comprising:

a first relief oil passage through which, when the first valve closes the first oil passage, operating oil in the first oil passage, the operating oil being located closer to the transmission than the first valve, is configured to be discharged.

14. The vehicle according to claim 2 , comprising:

15. The vehicle according to claim 3 , comprising:

16. The vehicle according to claim 4 , comprising:
