Abstract

A work vehicle includes a touch-panel display, at least one first physical button, and the circuitry. The touch-panel display is to display at least one first touch button, at least one first function, and work information. The at least one function is displayed in the at least one first touch button to which the at least one first function is assigned. The work information includes a state of work which the work vehicle performs. The at least one first physical button is provided outside the touch-panel display. The at least one first function is assigned to the at least one first physical button. The circuitry is configured to change the at least one first function assigned to the at least one first touch button and the at least one first physical button in accordance with the work information.

Claims

1. A work vehicle comprising:

a touch-panel display to display at least one first touch button, at least one first function displayed in the at least one first touch button to which the at least one first function is assigned, and work information including a state of work which the work vehicle performs;

at least one first physical button which is provided outside the touch-panel display and to which the at least one first function is assigned; and

circuitry configured to

change the at least one first function assigned to the at least one first touch button and the at least first physical button in accordance with the work information.

2. The work vehicle according to claim 1,

wherein the circuitry is configured to switch a display state of the at least one first touch button between a first display state and a second display state,

wherein the circuitry is configured to enable operations of both the at least one first touch button and the at least one first physical button when the display state of the at least one first touch button is switched to the first display state, and

wherein the circuitry is configured to disable operations of both the at least one first touch button and the at least one first physical button when the display state of the at least one first touch button is switched to the second display state.

3. The work vehicle according to claim 2, wherein the at least one first touch button is not displayed on the touch-panel display when the display state of the at least one first touch button is switched to the second display state.

4. The work vehicle according to claim 1,

wherein the at least one first touch button includes the first touch buttons arranged in a first line,

wherein the at least one first function includes the first functions which are different from each other, and

wherein the at least one first physical button includes the first physical buttons arranged in a second line substantially parallel to the first line, each of the first touch buttons corresponding to each of the first physical buttons in a sequential order, each of the first functions being assigned to a touch button of the first touch buttons and a physical button of the first physical buttons, the touch button corresponding to the physical button.

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

at least one second physical button provided adjacently to the at least one first physical button outside the touch-panel display,

wherein the touch-panel display is to display at least one second touch button which is provided adjacently to the at least one first touch button, at least one second function being assigned to the at least one second physical button and the at least one second touch button corresponding to the at least one second physical button, and

wherein the at least one second function is unchanged regardless of the work information displayed on the touch-panel display.

6. The work vehicle according to claim 4, further comprising:

second physical buttons arranged in a third line substantially parallel to and adjacent to the second line,

wherein the touch-panel display is to display second touch buttons arranged in a fourth line which is substantially parallel to and adjacent to the first line, each of the second touch buttons corresponding to each of the second physical buttons in a sequential order,

wherein second functions, which are different from each other, are assigned to the second touch buttons and the second physical buttons such that each of the second functions is assigned to a touch button of the second touch buttons and a physical button of the second physical buttons, the touch button corresponding to the physical button being arranged in the side direction, and

wherein the second functions are unchanged regardless of the work information displayed on the touch-panel display.

7. The work vehicle according to claim 5,

wherein the circuitry is configured to switch a display state of the at least one second touch button between a first display state and a second display state,

wherein the circuitry is configured to enable operations of both the at least one second touch button and the at least one second physical button when the display state of the at least one second touch button is switched to the first display state, and

wherein the circuitry is configured to disable operations of both the at least one second touch button and the at least one second physical button when the display state of the at least one second touch buttons is switched to the second display state.

8. The work vehicle according to claim 6,

wherein the circuitry is configured to switch each of display states of the second touch buttons between a first display state and a second display state,

wherein the circuitry is configured to enable operations of both each of the second touch buttons and each of the second physical buttons when the display state of each of the second touch buttons is switched to the first display state, and

when the circuitry is configured to disable operations of both each of the second touch buttons and each of the second physical buttons when the display state of each of the second touch buttons is switched to the second display state.

9. The work vehicle according to claim 5, wherein a touch-button display area where the at least one first touch button and the at least one second touch button are displayed is adjacent to a physical-button placement area where the at least one first physical button and the at least one second physical button are provided.

10. The work vehicle according to claim 6, wherein a touch-button display area where the first touch buttons and the second touch buttons are displayed is adjacent to a physical-button placement area where the first physical buttons and the second physical buttons are provided.

11. A display control method for a work vehicle, comprising:

displaying at least one first touch button, at least one first function, and work information on a touch-panel display, the at least one first function being displayed in the at least one first touch button to which the at least one first function is assigned, the work information including a state of work which the work vehicle performs; and

changing in accordance with the work information, the at least one first function assigned to the at least one first touch button and at least first physical button which is provided outside the touch-panel display.

12. A work vehicle comprising:

a touch-panel display to display at least one first touch button, at least one first function displayed in the at least one first touch button to which the at least one first function is assigned, and work information including a state of work which the work vehicle performs;

at least one first physical button which is provided outside the touch-panel display and to which the at least one first function is assigned; and

function changing means for changing the at least one first function assigned to the at least one first touch button and the at least first physical button in accordance with the work information.
