Abstract

A rear viewing arrangement is provided for a motor vehicle to permit the operator to view traffic conditions to rearward from left and right sides of the vehicle, as well as directly behind the vehicle. Left and right video cameras are mounted on the left and right sides of the motor vehicle forwardly of the drivers position. Each camera attachment has a miniature video camera viewing angle directed generally rearwards, and a housing or shroud that is in the form of an aerodynamic fairing disposed over the associated camera to protect the same and to minimize the amount of protuberance laterally from the side of the vehicle. The fairing also avoids unnecessary airflow turbulence, thereby streamlining the vehicle. The images viewed from these camera assemblies reproduced on an LCD viewing screen, which is integrated with the instrument cluster on the vehicle dashboard. The operator can easily observe the conditions to rearward without having to divert his or her attention from the road ahead.

Claims

1. Rear viewing arrangement for a motor vehicle to permit an operator in a driver'"'"'s position within the vehicle a view of traffic conditions to rearward from left and right sides of the motor vehicle, comprising:

left and right video camera arrangements respectively mounted on the left and right sides of the motor vehicle at a position at or forward of the said driver'"'"'s position; and

each said arrangement including a miniature video camera having a viewing angle directed generally rearwards, and a housing that is formed of a fairing disposed over the associated camera to protect same and minimize lateral protuberance from the side of the vehicle while avoiding unnecessary air flow turbulence, and a window on a rearward side of said fairing; and

at least one viewing screen coupled to said video camera arrangements and disposed at said driver'"'"'s position within the vehicle to reproduce left and right rearward views of the traffic conditions as viewed by said video cameras.

2. Rear viewing arrangement as recited in claim 1 wherein said fairings have a shape that is elongated in the longitudinal direction of said vehicle.

3. Rear viewing arrangement as recited in claim 2 wherein said fairings each have a forward edge forming a low angle between an outer surface of the fairing and the side of the vehicle.

4. Rear viewing arrangement as recited in claim 1, wherein said at least one viewing screen includes left and right LCD displays coupled respectively to the left and right video camera arrangements.

5. Rear viewing arrangement as recited in claim 4, wherein said left and right LCD displays are respectively positioned on left and right sides of a conventional center rear view mirror.

6. Rear viewing arrangement as recited in claim 1, further comprising a center viewing video camera arrangement mounted on said vehicle for viewing traffic conditions rearward from a centerline of said vehicle, and coupled to said at least one video display to provide at said driver'"'"'s position a center rearward view of traffic conditions.

7. Rear viewing arrangement as recited in claim 6, wherein said center viewing video camera arrangement is mounted on a roof of said vehicle behind said driver'"'"'s position.

8. Rear viewing arrangement as recited in claim 6, wherein said center viewing video camera arrangement is mounted within said vehicle adjacent a rear wind screen and oriented to view through the rear wind screen.

9. Rear viewing arrangement as recited in claim 6 wherein said at least one viewing screen includes left, center, and right LCD displays positioned at said driver'"'"'s position and respectively coupled to said left side, center viewing and right side camera arrangements.

10. Rear viewing arrangement as recited in claim 9 wherein said left, center, and right displays are integrated into a dashboard display.

11. Rear viewing arrangement as recited in claim 1 wherein said at least one viewing screen includes a target marker frame sized to correspond to a vehicle situated at a predetermined position in the viewing range of one of said cameras.

12. Rear viewing arrangement as recited in claim 1, further comprising at least one additional camera mounted at a corner of said vehicle and oriented for sidewards viewing, and coupled to said at least one viewing screen to provide a sideward view of traffic conditions from the associated corner of the vehicle.

13. Rear viewing arrangement as recited in claim 12 wherein said additional camera is mounted within a body member of said vehicle at the respective corner thereof.
