Abstract

A work vehicle capable of an autonomous travel includes a seat for a driver, a steering manipulator located in front of the seat and a display device configured to display information about the autonomous travel. The display device is located on one side in a left-right direction of the steering manipulator and includes a display that has a display screen configured to display information about the autonomous travel of the work vehicle and a manipulator connected to the display and having a manipulation member to enable operation associated with the autonomous travel.

First claim

1 . A work vehicle capable of an autonomous travel comprising:
a seat for a driver; a steering manipulator located in front of the seat; and a display device configured to display information about the autonomous travel, wherein the display device is located on one side in a left-right direction of the steering manipulator.

2 . The work vehicle according to claim 1 , wherein at least a part of the display device is positioned at the same height as the steering manipulator.

3 . The work vehicle according to claim 1 , wherein the display device is positioned on more front side than a rear end of the steering manipulator.

4 . The work vehicle according to claim 1 , wherein the display device is positioned in front of an armrest located on the side of the seat.

5 . The work vehicle according to claim 1 , wherein:
the display device includes a manipulator having manipulation members configured to perform an operation associated with the autonomous travel, the manipulation members include:
a first manipulation member configured to enable the autonomous travel to be switched on and off; and
a second manipulation member configured to enable operation different from operation of the first manipulation member, and
the first manipulation member is positioned closer to the steering manipulator than the second manipulation member is positioned to the steering manipulator.

6 . The work vehicle according to claim 1 , wherein:
a support member configured to support the display device is located in a cockpit having the seat and the steering manipulator, and the support member includes:
a support stay fixed to a frame that constitutes the cockpit; and
an arm member supported by the support stay that supports the display device, and
the arm member is provided to be rotatable around an axis extending in an up-down direction with respect to the support stay.

7 . The work vehicle according to claim 6 , wherein the support member has a restricter that is configured to restrict the arm member from rotating to an outer side in the left-right direction.

8 . The work vehicle according to claim 6 , wherein the display device is provided to be rotatable around an axis extending in the up-down direction with respect to the arm member.

9 . The work vehicle according to claim 6 , wherein the display device is provided to be rotatable around an axis extending horizontally with respect to the arm member.

10 . The work vehicle according to claim 1 , wherein:
a cabin is provided in a cockpit including the seat and the steering manipulator, and a support member to support the display device is attached to a frame for the cabin.

11 . The work vehicle according to claim 1 , wherein:
a mudguard is provided in a cockpit including the seat and the steering manipulator, and a support member to support the display device is attached to a frame for the mudguard.

12 . The work vehicle according to claim 1 , wherein a cockpit including the seat and the steering manipulator includes:
a pair of mudguard frames configured to support mudguards located on left and right sides of the cockpit; and a connection member configured to connect the pair of mudguard frames, and a support member configured to support the display device and that is attached to the connection member.

13 . The work vehicle according to claim 1 , wherein:
a support member configured to support the display device is located in a cockpit including the seat and the steering manipulator, the support member has:
a support stay fixed to a frame that constitutes the cockpit; and
an arm member supported by the support stay, and
the arm member is configured to be rotatable with respect to the support stay.

14 . The work vehicle according to claim 13 , wherein the display device includes:
a display having a display screen; and a manipulator having a manipulation member configured to perform operations associated with the autonomous travel, and wherein:
the display is mounted on the support stay, and
the manipulator is attached to the arm member.

15 . The work vehicle according to claim 14 , wherein the display is configured to be rotatable with respect to the support stay.

16 . A display device included in a work vehicle, the display device comprising:
a display that has a display screen configured to display information about an autonomous travel of the work vehicle; and a manipulator connected to the display and having a manipulation member configured to enable operation associated with the autonomous travel.

17 . The display device according to claim 16 , wherein the manipulator is located below the display.

18 . The display device according to claim 17 , wherein a surface on which the manipulation member of the manipulator is mounted is inclined with respect to the display screen.

19 - 20 . (canceled)

21 . The display device according to claim 16 , wherein the manipulation member includes at least a first manipulation member that includes:
the first manipulation member configured to enable the autonomous travel to be switched on and off, or a second manipulation member configured to enable operation different from operation of the first manipulation member.

22 - 26 . (canceled)

27 . A work vehicle comprising the display device according to claim 16 .
