Abstract

A display device of a working vehicle includes: a display screen configured to display an operation state of the working vehicle; an operation unit configured to switch display of the display screen; an abnormality detection unit configured to detect an abnormality of the working vehicle; an alarm output processing unit configured to perform an alarm output according to an abnormality detection state detected by the abnormality detection unit; and a cancellation function allocation unit configured to allocate a function to cancel the alarm output to the operation unit, wherein the alarm output processing unit performs processing of canceling the alarm output when an operation of the operation unit is performed in a state where the function to cancel the alarm output has been allocated.

Claims

1. A display device of a working vehicle, comprising:

a display screen configured to display an operation state of the working vehicle;

an operation unit configured to switch display of the display screen;

an abnormality detection unit configured to detect an abnormality of the working vehicle;

an alarm output processing unit configured to perform an alarm output according to an abnormality detection state detected by the abnormality detection unit; and

a cancellation function allocation unit configured to allocate a function to cancel the alarm output to the operation unit, wherein

the alarm output processing unit performs processing of canceling the alarm output when an operation of the operation unit is performed in a state where the function to cancel the alarm output has been allocated.

2. The display device of a working vehicle according to claim 1, wherein the cancellation function allocation unit allocates effectiveness/ineffectiveness of the function to cancel the alarm output to the operation unit according to the abnormality detection state detected by the abnormality detection unit.

3. The display device of a working vehicle according to claim 1, further comprising:

a screen display control unit configured to perform guide display that guides cancellation of the alarm output by the operation unit is possible on the display screen when the cancellation function allocation unit allocates the function to cancel the alarm output to the operation unit.

4. The display device of a working vehicle according to claim 3, wherein the screen display control unit performs guide display as a guide icon in a position on the display screen corresponding to a position of the operation unit.

5. The display device of a working vehicle according to claim 4, wherein the operation unit is arranged at an end portion of the display device, and the guide icon is arranged in an adjacent position corresponding to the operation unit and an end portion of the display screen.

13. The display device of a working vehicle according to claim 2, further comprising:

a screen display control unit configured to perform guide display that guides cancellation of the alarm output by the operation unit is possible on the display screen when the cancellation function allocation unit allocates the function to cancel the alarm output to the operation unit.

14. The display device of a working vehicle according to claim 13, wherein the screen display control unit performs guide display as a guide icon in a position on the display screen corresponding to a position of the operation unit.

15. The display device of a working vehicle according to claim 14, wherein the operation unit is arranged at an end portion of the display device, and the guide icon is arranged in an adjacent position corresponding to the operation unit and an end portion of the display screen.

6. A display device of a working vehicle, comprising:

a display screen configured to display an operation state of the working vehicle;

an operation unit configured to switch display of the display screen;

an abnormality detection unit configured to detect an abnormality of the working vehicle;

an alarm output processing unit configured to perform an alarm output according to an abnormality detection state detected by the abnormality detection unit;

a cancellation function allocation unit configured to allocate effectiveness/ineffectiveness of a cancellation function of the alarm output to a specific operation switch arranged at an upper right end of the operation unit according to the abnormality detection state detected by the abnormality detection unit; and

a screen display control unit configured to perform, when the cancellation function allocation unit allocates the cancellation function of the alarm output to a specific operation switch of the operation unit, guide display that guides cancellation of the alarm output by the specific operation switch is possible at an upper right end on the display screen and in a position corresponding to a position of the specific operation switch, wherein

the alarm output processing unit performs processing of canceling the alarm output when an operation of the specific operation switch is performed in a state where the cancellation function has been allocated to the alarm output.

7. A display method of a display device of a working vehicle including a display screen that displays an operation state of the working vehicle, and an operation unit that switches display of the display screen, the method comprising:

an abnormality detection step of detecting an abnormality of the working vehicle;

an alarm output processing step of performing an alarm output according to an abnormality detection state detected by the abnormality detection step;

a cancellation function allocation step of allocating a function to cancel the alarm output to the operation unit; and

an alarm output cancellation step of canceling the alarm output when an operation of the operation unit is performed in a state where the function to cancel the alarm output has been allocated.

8. The display method of a display device of a working vehicle according to claim 7, wherein the cancellation function allocation step allocates effectiveness/ineffectiveness of the function to cancel the alarm output to the operation unit according to the abnormality detection state detected by the abnormality detection step.

9. The display method of a display device of a working vehicle according to claim 7, further comprising:

a screen display control step of performing guide display that guides cancellation of the alarm output by the operation unit is possible on the display screen when the cancellation function allocation step allocates the function to cancel the alarm output to the operation unit.

10. The display method of a display device of a working vehicle according to claim 9, wherein the screen display control step performs guide display as a guide icon in a position on the display screen corresponding to a position of the operation unit.

11. The display method of a display device of a working vehicle according to claim 10, wherein the operation unit is arranged at an end portion of the display device, and the guide icon is arranged in an adjacent position corresponding to the operation unit and an end portion of the display screen.

16. The display method of a display device of a working vehicle according to claim 8, further comprising:

a screen display control step of performing guide display that guides cancellation of the alarm output by the operation unit is possible on the display screen when the cancellation function allocation step allocates the function to cancel the alarm output to the operation unit.

17. The display method of a display device of a working vehicle according to claim 16, wherein the screen display control step performs guide display as a guide icon in a position on the display screen corresponding to a position of the operation unit.

18. The display method of a display device of a working vehicle according to claim 17, wherein the operation unit is arranged at an end portion of the display device, and the guide icon is arranged in an adjacent position corresponding to the operation unit and an end portion of the display screen.

12. A working vehicle comprising the display device including:

a display screen configured to display an operation state of the working vehicle;

an operation unit configured to switch display of the display screen;

an abnormality detection unit configured to detect an abnormality of the working vehicle;
