Abstract

An operator interface for a work machine having a machine display system and a mechanical linkage is disclosed. The interface includes an input device having a series of input mechanisms that are adapted to generate a linkage input signal to control the motion of the mechanical linkage and that are adapted to generate a display input signal to input information to the machine display system. A control module is adapted to operate in a linkage control mode, where the motion of the mechanical linkage is controlled, and a display control mode, where the input of information to the machine display system is controlled. A switch may also be associated with the interface. The switch may be adapted to switch the operating mode between the linkage control mode and the display control mode.

Claims

a switch associated with the interface, the switch being adapted to switch the operating mode between the linkage control mode and the display control mode.

2. The interface of claim 1, wherein the switch is a toggle switch adapted to switch the operating mode of the control module between the linkage control mode and the display control mode.

3. The interface of claim 1, wherein the switch includes logic in the control module, adapted to switch the operating mode between the linkage control mode and the display control mode in response to a toggle signal.

4. The interface of claim 3, wherein the toggle signal is a predetermined manipulation of the input device.

5. The interface of claim 1, wherein control module is adapted to control at least one of a manipulation of information, a movement of a cursor, an input of information, and a selection of selectable functions based on the display input signal when the control module is operating in the display control mode.

6. The interface of claim 5, wherein the selectable functions include at least one of a selection of an operating mode, a selection of machine diagnostics, and a selection of a machine maintenance schedule.

7. The interface of claim 5, wherein the input of information includes at least one of an input of alpha characters, an input of numerical characters, and a selection of an icon.

8. The interface of claim 5, wherein the control module is adapted to control the input of information by at least one of a pop-up menu, a drop-down menu, a scrollable selection, and a selectable icon.

9. The interface of claim 1, wherein the control module is adapted to control the position of at least one of a plurality of hydraulic valves associated with the mechanical linkage in response to the linkage input signal when the control module is operating in the linkage control mode.

10. The interface of claim 1, wherein the input mechanisms of the input device include at least one of a trigger, a plurality of buttons, and a slider.
