Abstract

A vehicle system is disclosed that includes a vehicle lamp assembly including a plurality of LEDs that emit white light so as to function as an illuminator light. The lamp assembly also may include a plurality of LEDs that emit colored light to function as a signal light. The lamp assembly may include a camera. The lamp assembly may serve as a CHMSL or as a tail light. The system also includes a controller that rapidly pulses the LEDs at a rate that is imperceivable by the human eye. The pulsing intervals of the LEDs may be related to the readout intervals of the camera sensor array. In this manner, the LEDs may be pulsed on during camera readout to increase the illumination while the camera is capturing an image, or may be pulsed off during camera readout to prevent feedback glare from interfering with image capture by the camera.

Claims

1. A modular integrated vehicle window assembly comprising:

a window;

an opaque frit disposed on a peripheral region of said window;

a camera housing integrally mounted to an inner surface of said window behind a substantially transparent zone formed in said frit; and

a camera mounted in said camera housing so as to capture an image through said window and said substantially transparent zone formed in said frit.

2. The modular integrated vehicle window assembly as defined in claim 1 and further including a windshield wiper mounted to said window, wherein said camera is mounted behind a wiper zone defined by the sweep of said wiper across the outer surface of said window.

3. The modular integrated vehicle window assembly as defined in claim 1 and further including a window washer, wherein said camera is mounted behind a wash zone defined by the area in which said washer dispenses washer fluid.

4. The modular integrated vehicle window assembly as defined in claim 1 and further including a defroster disposed on said window, wherein said camera is mounted behind a defroster zone defined by the area covered on said window by said defroster.

5. A modular integrated vehicle window assembly comprising:

a window; and

a camera mounted to an inner surface of said window so as to capture an image through said window.

6. The modular integrated vehicle window assembly as defined in claim 5 and further including an opaque frit disposed on a peripheral region of said window, and said camera is mounted behind a transparent zone formed in said frit.

7. The modular integrated vehicle window assembly as defined in claim 5 and further including a windshield wiper mounted to said window, wherein said camera is mounted behind a wiper zone defined by the sweep of said wiper across the outer surface of said window.

8. The modular integrated vehicle window assembly as defined in claim 5 and further including a window washer, wherein said camera is mounted behind a wash zone defined by the area in which said washer dispenses washer fluid.

9. The modular integrated vehicle window assembly as defined in claim 5 and further including a defroster disposed on said window, wherein said camera is mounted behind a defroster zone defined by the area covered on said window by said defroster.

10. A modular integrated vehicle rear window assembly comprising:

a window frame structure for mounting to the rear of a vehicle;

a rear window mounted in said window frame structure; and

a camera mounted to said window frame structure so as to capture an image to the rear of the vehicle.

11. The modular integrated vehicle rear window assembly as defined in claim 10, wherein said rear window is made of privacy glass.

12. The modular integrated vehicle rear window assembly as defined in claim 10 and further including a radiation source mounted to said window frame structure for emitting radiation rearward of the vehicle.

13. The modular integrated vehicle rear window assembly as defined in claim 12, wherein said radiation source emits IR radiation.

14. The modular integrated vehicle rear window assembly as defined in claim 12, wherein said radiation source emits white light.

15. The modular integrated vehicle rear window assembly as defined in claim 12, wherein said radiation source emits light to which said camera is sensitive.

16. The modular integrated vehicle rear window assembly as defined in claim 10 and further including a light source mounted to said window frame structure.
