Abstract

The invention relates to a motor vehicle comprising a cab comprising a glass wall and an occultation system, the occultation system comprising a darkening device and being configured to allow the darkening device to move along a trajectory between an open position in which the darkening device does not obscure the glass wall and a closed position in which the darkening device obscures the glass wall, and a camera monitoring system comprising at least one camera configured to capture images of a scene outside the vehicle, and a display device configured to display the images captured by the camera, the display device being positioned in the cab, along the glass wall, wherein when the darkening device is in the closed position, the darkening device is configured to fully obscure the glass wall and to cover the display device.

First claim

The invention claimed is:

1. A motor vehicle comprising:
a cab comprising a glass wall and an occultation system, the glass wall comprising a windshield and a side window, the occultation system comprising a darkening device and being configured to allow the darkening device to move along a trajectory between an open position in which the darkening device does not obscure the glass wall and a closed position in which the darkening device obscures at least a portion of the side window and at least a portion of the windshield of the glass wall,
a camera monitoring system comprising at least one camera configured to capture images of a scene outside the vehicle, and a display device configured to display the images captured by the camera, the display device being positioned in the cab, along the glass wall, and
wherein when the darkening device is in the closed position, the darkening device is configured to obscure the at least a portion of the side window and the at least a portion of the windshield of the glass wall and to cover the display device, and
wherein the occultation system comprises a control unit configured to detect a position of the darkening device and configured to control the display device depending on the position of the darkening device.

2. The motor vehicle of claim 1 , wherein the control unit is configured to control the display device so that the display device is switched off when the darkening device is in the closed position.

3. The motor vehicle of claim 2 , wherein the control unit is configured to detect the closed position of the darkening device and is configured to switch off the display device when the control unit detects that the darkening device is in the closed position.

4. The motor vehicle of claim 2 , wherein the control unit is configured to detect that the darkening device is moved from the open position to the closed position and is configured to switch off the display device when the control unit detects that the darkening device is moved from the open position to the closed position.

5. The motor vehicle of claim 1 , wherein the occultation system comprises a rail on which the darkening device is slidably attached and the control unit comprises at least one sensor disposed on the rail and configured to detect the position of the darkening device.

6. The motor vehicle of claim 5 , wherein the at least one sensor is a switch configured to detect when the darkening device is slid over the switch and to switch off the display device when the darkening device is slid over the switch.

7. The motor vehicle of claim 5 , wherein the rail is disposed above the glass wall and the darkening device comprises an upper edge and a lower edge opposed to the upper edge, the darkening device being slidably attached by the upper edge to the rail and the lower edge being a free lower edge extending below the glass wall.

8. The motor vehicle of claim 7 , wherein the display device is disposed below the rail and wherein the sensor is aligned with the display device so that the sensor is switched off when the darkening device reaches the display device.

9. The motor vehicle of claim 5 , wherein among the at least one sensor, the control unit comprises a first sensor and a second sensor disposed on the rail and configured to detect the position of the darkening device.

10. The motor vehicle of claim 1 , wherein the display device is disposed on a pillar of the cab.

11. The motor vehicle of claim 1 , further comprising an additional display device positioned in the cab, out of the trajectory of the darkening device, and configured to display images captured by the camera of the monitoring system when the darkening device is in the closed position.

12. The motor vehicle of claim 11 , wherein the cab comprises a dashboard and wherein the additional display device is disposed on the dashboard.
