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 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;

a linkage connecting the first and second sets of louvers and arranged about a perimeter of the third opening such that the linkage does not obstruct a field of view of the object detection device; and

an actuator arranged at one end of the housing proximate an outer end of one of the first and second sets of louvers, the actuator being configured to selectively open/close the first and second sets of louvers by driving the one of the first and second sets of louvers.

2. The AGS system of claim 1, wherein the third opening is aligned with a cover 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.

3. The AGS system of claim 2, wherein the cover is a decorative emblem of the vehicle grille assembly.

4. The AGS system of claim 2, wherein the cover defines a thickness that provides for substantially uniform electromagnetic transmission.

5. The AGS system of claim 2, wherein the cover is part of the housing.

6. The AGS system of claim 1, further comprising a mounting device arranged in the third opening and configured to receive the object detection device.

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

8. The AGS system of claim 1, wherein the AGS system is semi-integrated into a grille assembly of the vehicle such that only a portion of the AGS system is integrated into the vehicle grille assembly.

9. The AGS system of claim 1, wherein the AGS system is fully-integrated into a grille assembly of the vehicle.

10. A system for a vehicle, the system comprising:

an object detection device configured to detect objects in front of the vehicle; and

an active grille shutter (AGS) system including;

a housing defining first, second, and third openings, the third opening being located between the first and second openings, wherein the object detection device is arrange proximate to the third opening;

a first set of louvers arranged in the first opening;

a second set of louvers arranged in the second opening;

a linkage connecting the first and second sets of louvers and arranged about a perimeter of the third opening such that the linkage does not obstruct a field of view of the object detection device; and

an actuator arranged at one end of the housing proximate an outer end of one of the first and second sets of louvers, the actuator being configured to selectively open/close the first and second sets of louvers by driving the one of the first and second sets of louvers.

11. The system of claim 10, wherein the object detection device is arranged in the third opening 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 protect the object detection device and allow acceptable transmission from/to the object detection device.

12. The system of claim 11, wherein the cover is a decorative emblem of the vehicle grille assembly.

13. The system of claim 11, further comprising a mounting device arranged in the third opening and configured to receive the object detection device.

14. The system of claim 11, wherein the cover defines a thickness that provides for substantially uniform electromagnetic transmission.

15. The system of claim 11, wherein the cover is part of the housing.

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

a housing;

an object detection device disposed within the housing and being configured to detect objects in front of the vehicle;

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

an active grille shutter (AGS) system disposed within the housing and defining first, second, and third openings of the housing, wherein the object detection device is arranged proximate to the third opening, the AGS system including;

a first set of louvers arranged in the first opening;

a second set of louvers arranged in the second opening;

a linkage connecting the first and second sets of louvers and arranged about a perimeter of the third opening such that the linkage does not obstruct a field of view of the object detection device; and

an actuator arranged at one end of the housing proximate an outer end of one of the first and second sets of louvers, the actuator being configured to selectively open/close the first and second sets of louvers by driving the one of the first and second sets of louvers.

17. The grille assembly of claim 16, wherein the third opening is aligned with the cover and the object detection device is mounted within the third opening by a mounting device of the AGS system.

18. The grille assembly of claim 16, wherein the cover defines a thickness that provides for substantially uniform electromagnetic transmission.

19. The grille assembly of claim 16, wherein the cover is part of the housing.

20. The grille assembly of claim 19, wherein the cover is a decorative emblem of the vehicle grille assembly.
