Abstract

A work vehicle includes a roof panel forming a portion of a cab of the work vehicle. The work vehicle also includes a headliner disposed between the roof panel and an interior of the cab. In addition, the work vehicle includes a spatial locating antenna positioned between the roof panel and the headliner, such that a top side of the roof panel is positioned above the spatial locating antenna relative to a ground surface. Furthermore, the top side of the roof panel extends beyond a lateral extent and a longitudinal extent of the spatial locating antenna.

First claim

The invention claimed is:

1. A work vehicle, comprising:
a roof panel forming a portion of a cab of the work vehicle;
a headliner disposed between the roof panel and an interior of the cab;
a first spatial locating antenna positioned between the roof panel and the headliner, such that a top side of the roof panel is positioned above the first spatial locating antenna relative to a ground surface, wherein the top side of the roof panel extends beyond a lateral extent and a longitudinal extent of the first spatial locating antenna;
a hood; and
a second spatial locating antenna positioned beneath the hood, wherein a top side of the hood is positioned above the second spatial locating antenna relative to the ground surface, and the top side of the hood extends beyond a lateral extent and a longitudinal extent of the second spatial locating antenna.

2. The work vehicle of claim 1 , wherein the first spatial locating antenna is communicatively coupled to a spatial locating device.

3. The work vehicle of claim 2 , wherein the first spatial locating antenna comprises a global positioning system (GPS) antenna, and the spatial locating device comprises a GPS receiver.

4. The work vehicle of claim 1 , comprising a second spatial locating antenna positioned between the roof panel and the headliner.

5. The work vehicle of claim 4 , wherein the first spatial locating antenna is positioned proximate to a first lateral end of the roof panel and to a first longitudinal end of the roof panel, and the second spatial locating antenna is positioned proximate to a second lateral end of the roof panel, opposite the first lateral end, and to a second longitudinal end of the roof panel, opposite the first longitudinal end.

6. The work vehicle of claim 1 , comprising a coating disposed on an outer surface of the top side of the roof panel, wherein the outer surface of the top side faces away from the first spatial locating antenna.

7. The work vehicle of claim 6 , wherein the coating includes a gap aligned with the first spatial locating antenna to facilitate passage of a spatial locating signal through the roof panel to the first spatial locating antenna.

8. The work vehicle of claim 7 , wherein the gap extends beyond the lateral extent of the first spatial locating antenna, the longitudinal extent of the first spatial locating antenna, or a combination thereof.

9. The work vehicle of claim 7 , comprising a second coating disposed on the outer surface of the top side of the roof panel within the gap, wherein the second coating is configured to facilitate passage of the spatial locating signal to the first spatial locating antenna.

10. A work vehicle, comprising:
a body;
a spatial locating antenna positioned beneath the body, wherein a top side of the body is positioned above the spatial locating antenna relative to a ground surface, and the top side extends beyond a lateral extent and a longitudinal extent of the spatial locating antenna;
a first coating disposed on an outer surface of the top side of the body, wherein the outer surface of the top side faces away from the spatial locating antenna, and the first coating includes a gap aligned with the spatial locating antenna to facilitate passage of a spatial locating signal through the body to the spatial locating antenna; and
a second coating disposed on the outer surface of the top side of the body within the gap, wherein the second coating comprises a paint layer, and the second coating is configured to facilitate passage of the spatial locating signal to the spatial locating antenna.

11. The work vehicle of claim 10 , wherein the gap extends beyond the lateral extent of the spatial locating antenna, the longitudinal extent of the spatial locating antenna, or a combination thereof.

12. The work vehicle of claim 10 , wherein the second coating comprises a top coat layer disposed on an outer surface of the paint layer.

13. The work vehicle of claim 10 , wherein the body comprises a roof panel forming a portion of a cab of the work vehicle, and the spatial locating antenna is positioned beneath the roof panel.

14. The work vehicle of claim 13 , comprising a second spatial locating antenna, wherein the body comprises a hood, and the second spatial locating antenna is positioned beneath the hood.

15. A work vehicle, comprising:
a roof panel forming a portion of a cab of the work vehicle;
a first spatial locating antenna positioned beneath the roof panel, such that a top side of the roof panel is positioned above the first spatial locating antenna relative to a ground surface, wherein the top side of the roof panel extends beyond a lateral extent and a longitudinal extent of the first spatial locating antenna;
a coating disposed on an outer surface of the top side of the roof panel, wherein the outer surface of the top side of the roof panel faces away from the first spatial locating antenna, and the coating is configured to facilitate passage of a spatial locating signal through the roof panel to the first spatial locating antenna,
a hood; and
a second spatial locating antenna positioned beneath the hood, wherein a top side of the hood is positioned above the second spatial locating antenna relative to the ground surface, and the top side of the hood extends beyond a lateral extent and a longitudinal extent of the second spatial locating antenna.

16. The work vehicle of claim 15 , comprising a headliner disposed between the roof panel and an interior of the cab, wherein the first spatial locating antenna is positioned between the roof panel and the headliner.

17. The work vehicle of claim 15 , comprising a second spatial locating antenna positioned beneath the roof panel.

18. The work vehicle of claim 17 , wherein the first spatial locating antenna is positioned proximate to a first lateral end of the roof panel and to a first longitudinal end of the roof panel, and the second spatial locating antenna is positioned proximate to a second lateral end of the roof panel, opposite the first lateral end, and to a second longitudinal end of the roof panel, opposite the first longitudinal end.
