Abstract

Embodiments of the present disclosure are directed to vehicles and vehicle roof structures for concealing one or more sensors. Vehicle roof structures according to the present disclosure include a roof panel and a window extending at least up to the roof panel. A headliner extends along an interior portion of the roof panel to the window and is at least partially spaced from the roof panel in a direction of an interior of the vehicle to provide a sensor mounting volume therebetween, wherein the window extends along at least a portion of the sensor mounting volume. One or more sensors are positioned behind the window within the sensor mounting volume to provide a signal indicative of a characteristic of an environment of the vehicle detected by the one or more sensors through the window.

Claims

1. A vehicle roof structure for concealing one or more sensors comprising:

a roof panel comprising a window receiving portion;

a front header supporting the roof panel;

a window extending toward the roof panel and supported on the window receiving portion of the roof panel;

a headliner extending along an interior portion of the roof panel to the window and at least partially spaced from the roof panel in a direction of an interior of the vehicle to provide a sensor mounting volume therebetween, wherein the window extends along at least a portion of the sensor mounting volume; and

one or more sensors coupled to the window receiving portion of the roof panel at a position forward of the front header in a vehicle longitudinal direction and positioned behind the window within the sensor mounting volume to provide a signal indicative of a characteristic of an environment of the vehicle detected by the one or more sensors through the window.

2. The vehicle roof structure of claim 1, wherein the window comprises a lower portion and a transition portion, the transition portion of the window comprises a shade band.

3. The vehicle roof structure of claim 2, wherein the shade band of the transition portion of the window is provided by at least one of window tinting and black ceramic paint.

4. The vehicle roof structure of claim 2, wherein the transition portion of the window further comprises one or more sensor regions and a concealing region, wherein the one or more sensor regions has greater visible light transmission than the concealing region.

5. The vehicle roof structure of claim 2, wherein the transition portion of the window is integral with the lower portion of the window.

6. The vehicle roof structure of claim 2, wherein the transition portion of the window is a separate panel from the lower portion of the window.

7. The vehicle roof structure of claim 6, wherein a thickness of the transition portion of the window is less than a thickness of the lower portion of the window.

8. The vehicle roof structure of claim 1 further comprising one or more sensor brackets, wherein the one or more sensor brackets are coupled to the window receiving portion of the roof panel.

9. A vehicle roof structure for concealing one or more sensors comprising:

a roof panel comprising one or more sensor cavities formed therein;

a window extending by the one or more sensor cavities and supported on the roof panel at a position forward of the one or more sensor cavities in a vehicle longitudinal direction; and

one or more sensors positioned within the one or more sensor cavities of the roof panel to provide a signal indicative of a characteristic of an environment of the vehicle detected by the one or more sensors through the window.

10. The vehicle roof structure of claim 9, wherein the window comprises a lower portion and a transition portion, the transition portion of the window having reduced visible light transmission.

11. The vehicle roof structure of claim 10, wherein the transition portion of the window is substantially curved relative to the lower portion of the window to substantially blend with the roof panel.

12. The vehicle roof structure of claim 10, wherein a thickness of the transition portion of the window is less than a thickness of the lower portion of the window.

13. The vehicle roof structure of claim 9, wherein the one or more sensors are at least one of LiDAR, vehicle-to-vehicle communication, camera, radar, and laser.

14. The vehicle roof structure of claim 9, wherein the one or more sensors are a plurality of sensors positioned along a width of the window.

15. The vehicle roof structure of claim 9, wherein:

the one or more sensors are communicatively coupled to one or more processors;

the one or more processors receive from the one or more sensors the signal indicative of the characteristic of the environment; and

the one or more processors execute logic to cause the vehicle to respond to the signal indicative of the characteristic of the environment from the one or more sensors.

16. A vehicle for concealing one or more sensors comprising:

a roof structure comprising;

a roof panel comprising a window receiving portion;

a front header supporting the roof panel;

a window extending toward the roof panel and supported on the window receiving portion of the roof panel;

a headliner extending along an interior portion of the roof panel to the window and at least partially spaced from the roof panel in a direction of an interior of the vehicle to provide a sensor mounting volume therebetween, wherein the window extends along at least a portion of the sensor mounting volume; and

one or more sensors coupled to the window receiving portion of the roof panel at a position forward of the front header in a vehicle longitudinal direction and positioned behind the window and within the sensor mounting volume to provide a signal indicative of a characteristic of an environment of the vehicle detected by the one or more sensors through the window; and

one or more processors communicatively coupled to the one or more sensors to receive from the one or more sensors the signal indicative of the characteristic of the environment and execute logic to cause the vehicle to respond to the signal indicative of the characteristic of the environment received from the one or more sensors.

17. The vehicle of claim 16, wherein the roof structure further comprises one or more sensor brackets coupled the one or more sensors to couple the one or more sensors to the roof panel.

18. The vehicle of claim 16, wherein the one or more sensors are at least one of LiDAR, vehicle-to-vehicle communication, camera, radar, and laser.

19. The vehicle of claim 16, wherein the window comprises a lower portion and a transition portion, the transition portion of the window having reduced visible light transmission.

20. The vehicle of claim 16, wherein the roof structure further comprises one or more sensor brackets, wherein the one or more sensor brackets are coupled to the window receiving portion of the roof panel, wherein the one or more sensor brackets are coupled to the one or more sensors to direct the one or more sensors toward the window of the vehicle.
