Abstract

Disclosed embodiments include power machines having doors with a display that allows the display of information, such as gauges, user inputs, mapped obstacles, boundaries, etc., allowing the operator of the machine to see the displayed information closer to the line of sight with the work area.

Claims (44)

1 . A power machine comprising:

a cab;

a cab door moveable with respect to the cab between a closed position and an open position and configured to allow an operator to enter into and exit out of the cab when in the open position;

a display configured to display information to the operator of the power machine, the display being visible to the operator when looking through the cab door when the cab door is in the closed position, and the display configured to allow at least partial visibility through the door to view a work area outside of the cab; and

wherein at least one transparent material of the door or cab has been treated with a material to reduce glare to improve visibility of the displayed information provided by the display.

2 . The power machine of claim 1 , wherein the display includes a heads-up display system with a rear projection display device configured to display the information on a transparent material positioned in front of the operator in the cab.

3 . The power machine of claim 1 , wherein the display includes display material integrated into the cab door.

4 . The power machine of claim 3 , wherein the display with the display material integrated into the cab door is a touchscreen display allowing the operator to provide input through the display to control one or more machine functions and/or display parameters.

5 . The power machine of claim 4 , wherein the touchscreen display is configured to control the one or more display parameters by selecting information to be displayed.

6 . The power machine of claim 5 , wherein the touchscreen display is configured to allow the operator to reconfigure the display of information.

7 . The power machine of claim 1 , wherein the display is configured to display augmented control information.

8 . The power machine of claim 7 , wherein the display being configured to display augmented control information includes the display being configured to display augmented reality images for the work area, the augmented reality images including at least one of representations of obstructions, defined paths, virtual roads, and boundaries.

9 . The power machine of claim 1 , wherein the cab door is located over an opening at a front of the cab.

10 . A power machine comprising:

a cab;

a cab door moveable between a closed position and an open position with respect to the cab and configured to allow an operator to enter into and exit out of a front of the cab when the cab door is in the open position; and

a display integrated into the cab door, the display having display material, including a layer of transparent material, the display material configured to generate images to display information to the operator of the power machine when the door is in the closed position while also allowing at least partial visibility through the display material of a work area outside of the cab.

11 . The power machine of claim 10 , wherein the display with the display material integrated into the cab door is a touchscreen display allowing the operator to provide input through the display to control one or more machine functions and/or display parameters.

12 . The power machine of claim 11 , wherein the touchscreen display is configured to control the one or more display parameters by selecting information to be displayed responsive to operator touchscreen input.

13 . The power machine of claim 12 , wherein the touchscreen display is configured to allow the operator to reconfigure the display of information.

14 . A power machine comprising:

a cab;

a cab door including a window, the cab door moveable with respect to the cab and configured to allow an operator to enter into and exit out of a front of the cab;

a display arranged adjacent to the window and visible to the operator when looking through the cab door, the display having display material, including a layer of transparent material, the display material configured to allow at least partial visibility through the display material of a work area outside of the cab, the display further configured to display information to the operator of the power machine; and

a controller configured to control the display to display augmented reality information.

15 . The power machine of claim 14 , wherein the augmented reality information includes augmented reality images for the work area.

16 . The power machine of claim 15 , wherein the augmented reality images include representations of obstructions.

17 . The power machine of claim 15 , wherein the augmented reality images include representations of at least one of defined paths, virtual roads, and boundaries.

18 . The power machine of claim 14 , wherein the display includes a heads-up display system with a rear projection display device configured to display the augmented reality information on a transparent material positioned in front of the operator in the cab.

19 . The power machine of claim 14 , wherein the display includes display material integrated into the cab door.

20 . A power machine comprising:

a cab;

a cab door moveable with respect to the cab and configured to allow an operator to enter into and exit out of the cab; and

a touchscreen display integrated into the cab door, the touch screen display having display material, including a layer of transparent material, the display material configured to generate images to display information to the operator of the power machine while allowing at least partial visibility through the display material of a work area outside of the cab, the touchscreen display configured to allow the operator to provide input through the touchscreen display to control one or more machine functions and/or display parameters.

21 . The power machine of claim 20 , wherein the touchscreen display is configured to control the one or more display parameters by selecting information to be displayed.

22 . The power machine of claim 21 , wherein the touchscreen display is configured to allow the operator to reconfigure the display of information.

23 . A power machine comprising:

a frame;

a cab mounted on the frame;

a lift arm mounted to the frame and capable of moving under power to perform a work function;

a transparent surface on a portion of the cab, that allows an operator to see outside the cab;

a display configured to display information to the operator of the power machine, the display being visible to the operator when looking through the transparent surface, and the display configured to allow at least partial visibility through the transparent surface to view a work area outside of the cab; and,

wherein the transparent surface on the portion of the cab includes a tinting material to reduce glare or washout to improve visibility of the displayed information provided by the display.

24 . The power machine of claim 10 , wherein at least one transparent material of the cab door having the display integrated therein or other transparent material of the cab has been treated with a tint material to improve visibility of the displayed information.
