Abstract

A peripheral viewing system for a vehicle includes a pair of digital cameras, each positioned on the exterior of the vehicle proximately positioned where a side view mirror would typically be mounted. An additional digital camera is mounted on the vehicle roof immediately adjacent the top edge of the rear window. A plurality of LCD'"'"'s each discretely associated with a corresponding camera are mounted within the vehicle passenger compartment at a location that is readily observable by the vehicle driver. The driver can panoramically view trailing traffic by observing the LCD'"'"'s in the passenger compartment. One or more infrared phototransistor receivers are positioned at the rear of the vehicle for detecting oncoming vehicles. If the driver attempts to change lanes and activates a turn signal, a warning message will be emitted within the passenger compartment if any of the transistors detect an approaching vehicle within a predetermined range of the vehicle.

Claims

1. A peripheral viewing system for a vehicle wherein said vehicle includes two opposing sides, a steering wheel positioned within a passenger compartment and a rear, the viewing system comprising:

a pair of cameras, one of said cameras mounted on one of said sides of the vehicle, another of said cameras mounted on another of said sides of the vehicle;

a pair of video displays mounted within said passenger compartment, and positioned therein to be readily visible by a driver, each video display in selective communication with a designated one of said cameras;

a microprocessor means in communication with each of said cameras and said displays for continuously processing images received from each of said cameras and for continuously transmitting said images to each of said displays;

a third camera mounted on the rear of said vehicle, said third camera connected to said microprocessor means;

a third video display mounted within the vehicle passenger compartment, said third video display in selective communication with said third camera via said microprocessor means for continuously depicting images behind said vehicle;

a warning means for alerting a driver of an approaching vehicle;

wherein said warning means comprises;

a phototransistor mounted on each side of said vehicle, adjacent the rear thereof, each of said phototransistors electrically connected to said microprocessor means;

an audible alarm means electrically connected to said microprocessor means for audibly alerting a driver if said phototransistors detect a trailing vehicle within a predetermined range of said vehicle;

wherein said vehicle includes a turn signal switch means electrically connected to said microprocessor means for exclusively activating said audible alarm means if said trailing vehicle is within the predetermined range of said vehicle.

2. The system according to claim 1 wherein each of said cameras is encased within a contoured, aerodynamic housing to minimize wind drag.

3. The system according to claim 2 wherein one of said displays is positioned immediately adjacent a first side of the steering wheel and another of said displays is positioned immediately adjacent an opposing side of the steering wheel.

4. The system according to claim 3 wherein said third camera is immediately adjacent a top edge of a rear window on the vehicle for replacing a conventional rear view mirror.
