Abstract

The invention comprises an ergonomically efficient rear and/or side view monitoring system wherein a video camera is mounted at the rear and/or sides of a vehicle and transmits images to a viewing screen which is integrally mounted in a side view mirror arrangement and displays a mirrored image of a rear view as an insertion to the reflective mirrored view of the side view mirror.

Claims

1. An ergonomically efficient arrangement for viewing by a driver from a vehicular driving compartment, comprising a video camera and a video display screen in enabling arrangement;

said video camera being mounted for viewing an area obstructed from said driver'"'"'s casual view;

said video display screen being mounted exterior to the driver compartment, contiguous with a reflected view means; and

, said video camera cooperating with said video display screen which enables generation of a video image on said screen which is consistent with the reflected image of said reflected view means.

2. The arrangement of claim 1 wherein said reflected view means comprises a mirrored surface mounted exterior to the driving compartment.

3. The arrangement of claim 1 wherein said reflected view means comprises a reflective element containing a transparent surface and an image reflecting surface.

4. The arrangement of claim 3 wherein the view means comprises a side view mirror which is adjustably mounted to the side of the driving compartment.

5. The arrangement of claim 3 wherein a generally flat video display screen is positioned behind the transparent surface and a driver views the screen through the transparent surface.

6. The arrangement of claim 5 wherein the display screen is mounted contiguous with the mirrored surface.

7. The arrangement of claim 6 wherein the display screen and mirrored surface are encased in weather resistant means.

8. The arrangement of claim 7 comprising environment control means.

9. The arrangement of claim 8 wherein said environment control means comprises at least one of temperature sensing, and heating and cooling means.

10. The arrangement of claim 5 wherein said display screen comprises a surface which is reflective when the display is deactivated.

11. The arrangement of claim 10 comprising video display screen deactivating means and upon deactivation of said display screen said surface of said display screen which is reflective, generally appears as contiguous with said reflected view means said display screen.

12. The arrangement of claim 1 comprising a plurality of video display screens.

13. The arrangement of claim 12 wherein said plurality of display screens are interconnected with a plurality of video cameras.

14. The arrangement of claim 1 comprising a video display screen capable of simultaneously displaying images from a plurality of video cameras.

15. The arrangement of claim 1 wherein said video display image is a direct view image from a video camera.

16. The arrangement of claim 1 comprising means for the driver to activate and deactivate said video display screen.

17. The arrangement of claim 1 comprising means for said driver to adjust the image of said video display screen.

18. The arrangement of claim 1 wherein said video camera is mounted within a lighting assembly.

19. The arrangement of claim 18 wherein said lighting assembly comprises environment control means.

20. The arrangement of claim 19 wherein said environment control means comprises at least one of temperature sensing, and heating and cooling means.

21. The arrangement of claim 18 comprising at least one of ranging sensing and motion detecting means.

22. An ergonomically efficient viewing mirror assembly, comprising a reflective element and a video display screen;

said reflective element comprising a transparent component and a reflective surface;

said video display screen being mounted juxtapositioned with said transparent component such that an image on said screen is visible through said transparent component of said reflective element and in continuity with a reflected image visible from said reflective surface.

23. The viewing mirror assembly of claim 22 wherein said video display screen comprises a flat panel display screen.

24. The viewing mirror of claim 22 wherein said reflective surface is elongated, and said viewing mirror assembly comprises means for adjustably mounting said assembly to a side of a vehicle.

25. The viewing mirror assembly of claim 22 wherein said video display screen comprises flat panel display means.

26. The viewing mirror assembly of claim 22 comprising enabling circuitry to provide a mirrored image on the display screen of a rearward view.

27. The viewing mirror assembly of claim 22 comprising means for enabling viewing of a display image on said display screen at the control of the driver.

28. The viewing mirror assembly of claim 22 comprising at least one of temperature sensing, and heating and cooling means.
