Abstract

Apparatus permitting viewing of traffic conditions to the rear and side of a motor vehicle, which has opposite sides, comprises:

(a) first and second video cameras and first and second display terminals having video screens, the cameras connected to the screens, respectively,

(b) the first and second cameras mounted to the vehicle at the respective opposite sides thereof, the cameras directed generally toward the rear of the vehicle,

(c) and the screens carried by the vehicle proximate the driver'"'"'s position, to be viewed by the driver in that position.

Claims

1. Apparatus to permit viewing of traffic conditions to the rear and side of a motor vehicle, which has opposite sides, comprising:

(a) first and second video cameras and first and second display terminals having video screens, the cameras connected to the screens, respectively,

(b) first and second means mounting the first and second cameras to the vehicle at the respective opposite sides thereof, the cameras directed generally toward the rear of the vehicle,

(c) and third an fourth means mounting the screens to the vehicle proximate the driver'"'"'s position, to be viewed by the driver in said position.

2. The combination of claim 1 wherein at least one of said first and second mounting means includes swiveling means to swivel the associated camera in at least one of the following modes:

(i) up and down

(ii) side to side during operation of that camera.

3. The combination of claim 1 wherein each of the first and second mounting means including swiveling means to swivel the associated camera in at least one of the following modes:

(i) up and down

(ii) side to side

4. The combination of claim 1 wherein said third and fourth means include actuator means to raise and lower said screens, within the vehicle interior, said actuator means carried by the vehicle.

5. The combination of claim 1 including at least one rear-view mirror mounted at a side of the vehicle, and in operative association with at least one of said video cameras.

6. The combination of claim 5 wherein the mirror is metallized to pass light therethrough to the camera, and also to reflect light toward the vehicle driver, in the vehicle.

7. The combination of claim 1 wherein said first and second mounting means include actuators connected with the cameras to bodily move the cameras toward and away from the sides of the vehicle.

8. The combination of claim 7 wherein the mounting means include linkages supporting the cameras for said bodily movement by the actuators.

9. The combination of claim 7 including respective housings at opposite sides of the vehicle into and from the cameras are displaced by the actuators.

10. The combination of claim 9 wherein said housings are defined by wells in the sides of the vehicle.

11. The combination of claim 10 wherein said housings have doors, and including door actuators controllable by the driver, within the vehicle, to open and close the doors relative to the wells.

12. In combination:

(a) a vehicle having a side, and a driver compartment,

(b) a video camera mounted at the vehicle side to scan conditions at the rear of the vehicle,

(c) a video display unit having a screen observable by the driver as he faces forwardly, in said compartment, said unit operatively connected with the camera to display what is scanned by the camera,

(d) and a rear view mirror mounted at the side of the vehicle to pass light to the camera and to reflect light to the passenger compartment for viewing by the driver.

13. Apparatus to permit viewing of traffic condition to the rear and side of a motor vehicle, which has opposite sides, comprising

(a) first and second video cameras and display terminal CRT means having two video screen portions, the cameras connected to the CRT mean so that one screen portion display output from one camera, and the other screen portion display output from the other cameras,

(b) first and second means mounting the first and second cameras to the vehicle at the respective opposite sides thereof, the cameras directed generally toward the rear of the vehicle,

(c) and means mounting the CRT means to the vehicle for viewing of said screen portions by the driver in the vehicle.

14. Apparatus to permit viewing of traffic conditions to the rear and side of a motor vehicle, which has opposite sides, comprising

(a) video camera means mounted to the side of the vehicle and directed rearwardly at said side, and CRT means connected to the camera to display its output on a screen to be viewed by the driver,

(b) and driver means connected to the camera means to substantially constantly swivel the camera means in at least one of the following modes:

(i) up and down

(ii) side to side

during operation of that camera means.
