Abstract

An active grille shutter (AGS) system for a vehicle can include a housing defining first, second, and third openings, the third opening being located between the first and second openings and being configured to receive an object detection device that is configured to detect objects in front of the vehicle, a first set of louvers arranged in the first opening, a second set of louvers arranged in the second opening, and a linkage connecting the first and second sets of louvers, wherein a set of actuators are configured to selectively open/close the first and second sets of louvers by driving the linkage or at least one of the first and second sets of louvers. The AGS system can be configured to be fully-integrated, semi-integrated, or standalone with respect to a grille assembly of the vehicle.

Claims

1. An active grille shutter (AGS) system for a vehicle, the AGS system comprising:

a housing defining (i) a central portion configured to align with an object detection device that is configured to detect objects in front of the vehicle and (ii) an outer portion that is distinct from the central portion;

a plurality of louvers disposed in the outer portion of the housing;

a linkage arranged about at least a portion of a perimeter of the central portion of the housing such that the linkage does not obstruct a field of view of the object detection device, the linkage connecting at least two louvers of the plurality of louvers; and

a set of one or more actuators configured to selectively open/close the plurality of louvers by driving at least one of (i) the linkage and (ii) at least one of the plurality of louvers.

2. The AGS system of claim 1, wherein the set of actuators are arranged proximate to the central portion of the housing.

3. The AGS system of claim 2, wherein at least some of the set of actuators are arranged below the central portion of the housing and the linkage.

4. The AGS system of claim 1, wherein a height of the central portion is less than a height of the outer portion.

5. The AGS system of claim 1, wherein the object detection device is aligned with the central portion and arranged behind a cover, wherein the cover is arranged in front of the object detection device and within or behind a grille assembly of the vehicle, and wherein the cover is configured to protect the object detection device and allow acceptable transmission from/to the object detection device.

6. The AGS system of claim 5, wherein the cover is part of the housing.

7. The AGS system of claim 5, wherein the cover is connected to or is part of the vehicle grille assembly.

8. The AGS system of claim 5, wherein the cover defines a thickness that provides for substantially uniform electromagnetic transmission.

9. The AGS system of claim 1, further comprising a mounting device configured to attach the object detection device to the housing.

10. The AGS system of claim 1, wherein the AGS system is a separate, standalone system with respect to a grille assembly of the vehicle.

11. The AGS system of claim 1, wherein the AGS system is semi-integrated into a grille assembly of the vehicle such that the plurality of louvers define a B-side of the vehicle grille assembly.

12. The AGS system of claim 1, wherein the AGS system is fully-integrated into a grille assembly of the vehicle such that the plurality of louvers define an A-side of the vehicle grille assembly.

13. A grille assembly for a vehicle, the grille assembly comprising:

a housing defining (i) a central portion configured to align with an object detection device that is configured to detect objects in front of the vehicle, (ii) an outer portion that is distinct from the central portion;

a cover arranged in front of the object detection device; and

an active grille shutter (AGS) system at least partially disposed within the housing and including;

a plurality of louvers disposed in the outer portion of the housing;

a linkage arranged about at least a portion of a perimeter of the central portion of the housing such that the linkage does not obstruct a field of view of the object detection device, the linkage connecting at least two louvers of the plurality of louvers; and

a set of one or more actuators configured to selectively open/close the plurality of louvers by driving at least one of (i) the linkage and (ii) at least one of the plurality of louvers.

14. The grille assembly of claim 13, wherein the set of actuators are arranged proximate to the central portion of the housing.

15. The grille assembly of claim 14, wherein at least some of the set of actuators are arranged below the central portion of the housing and the linkage.

16. The grille assembly of claim 13, wherein a height of the central portion is less than a height of the outer portion.

17. The grille assembly of claim 13, wherein the cover is part of the AGS system.

18. The grille assembly of claim 13, wherein the cover is connected to or is part of the housing of the grille assembly.

19. The grille assembly of claim 13, wherein the cover defines a thickness that provides for substantially uniform electromagnetic transmission.

20. The grille assembly of claim 13, further comprising a mounting device configured to connect the object detection device to at least one of (i) the AGS system and (ii) the housing of the grille assembly.
