Abstract

A vehicle cab having a moveable roof section. The movement of the roof section is based on the location of the sun relative to the vehicle cab, such that the roof section moves to act as a sun shade for the cab. The roof section is provided with a sun sensor to determine the sun location, so that the roof section can automatically move to provide an adaptive sun shade.

First claim

The invention claimed is:

1. An agricultural vehicle cab having:
a cab window section providing a panoramic view from an interior of the cab;
a single roof section provided on top of the cab; and
a sun sensor,
wherein the single roof section is moveable relative to the cab window section to shade the interior of the cab, and wherein the movement of the single roof section is controlled based on the position of the sun determined by the sun sensor, and wherein the agricultural vehicle cab comprises a first actuator to effect longitudinal movement of the single roof section relative to the cab window section, and wherein the agricultural vehicle cab comprises a second actuator to effect lateral movement of the single roof section relative to the cab window section such that the single roof section can be moved in the longitudinal and the lateral directions anywhere between extreme forward and aft longitudinal positions and extreme side-to-side lateral positions above the cab window section.

2. The agricultural vehicle cab of claim 1 , wherein the cab comprises a panoramic cab, having a substantially unobstructed cab window section.

3. The agricultural vehicle cab of claim 1 , wherein the roof section comprises at least one telescopic element arranged to extend and retract based on the position of the sun measured by the sun sensor.

4. The agricultural vehicle cab of claim 1 , wherein the agricultural vehicle cab further comprises a user interface to provide user control of the roof section position.

5. The agricultural vehicle cab of claim 1 , wherein a reflective material is provided on at least a portion of the roof section, such that the reflective material acts to reflect solar radiation away from the agricultural vehicle cab.

6. The agricultural vehicle cab of claim 1 , wherein the first or second actuators comprise at least one of the following: a rack-and-pinion actuation element, a hydraulic actuator, an electric motor.

7. The agricultural vehicle cab of claim 1 , wherein the agricultural vehicle cab further comprises a rain sensor and/or a wind direction sensor, wherein movement of the roof section is controlled at least in part based on the detection of rain by the rain sensor and/or on the wind direction at the agricultural vehicle cab.

8. The agricultural vehicle cab of claim 1 , wherein the agricultural vehicle cab further comprises an accelerometer or directional sensor, wherein the movement of the roof section is based at least in part on the direction of movement of the agricultural vehicle cab detected by the accelerometer or directional sensor.

9. The agricultural vehicle cab of claim 1 , wherein the agricultural vehicle cab further comprises an inclinometer, wherein the movement of the roof section is based at least in part on the incline or orientation of the agricultural vehicle cab.

10. The agricultural vehicle cab of claim 1 , wherein the agricultural vehicle cab further comprises a position sensor, wherein the movement of the roof section is based at least in part on the position of the agricultural vehicle cab.

11. The agricultural vehicle cab of claim 10 , wherein the position sensor comprises a GNSS sensor.

12. The agricultural vehicle cab of claim 1 , wherein the roof section is provided with at least one photovoltaic element to generate power for supply to a power consumer.

13. An agricultural vehicle having an agricultural vehicle cab as claimed in claim 1 .
