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 including two opposing sides, a steering wheel positioned within a passenger compartment, and a rear, the peripheral viewing system comprising:

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

a pair of video displays mounted separately in different locations within the passenger compartment, wherein the pair of video displays are positioned to be readily visible by a driver, and wherein each video display are in selective communication with a designated one of the pair of cameras;

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

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

a third video display mounted separately from the pair of video displays within the vehicle passenger compartment, wherein the third video display is in selective communication with the third camera using the microprocessor means for continuously depicting images behind the vehicle; and

a warning means for alerting a driver of an approaching vehicle, wherein the warning means comprises;

one or more phototransistors, each mounted on each side of the vehicle and adjacent the rear of the vehicle, wherein each phototransistor is electrically connected to the microprocessor means;

an audible alarm means electrically connected to the microprocessor means for audibly alerting a driver if one of the one or more phototransistor detects a trailing vehicle within a predetermined range of the vehicle;

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

2. The peripheral viewing system according to claim 1, wherein the third camera is immediately adjacent a top edge of a rear window on the vehicle for replacing a conventional rear view mirror.

3. The peripheral viewing system according to claim 1, wherein each the pair of cameras is encased within a contoured, aerodynamic housing to minimize wind drag.

4. The peripheral viewing system according to claim 1, wherein one of the pair of displays is positioned immediately adjacent a first side of the steering wheel and another of the pair of displays is positioned immediately adjacent an opposing side of the steering wheel.

5. A system for providing warning to a driver of a vehicle that includes two opposing sides, a steering wheel positioned within a passenger compartment, and a rear, the system comprising:

a microprocessor means mounted within the passenger compartment;

one or more phototransistors, each mounted on each side of the vehicle and adjacent the rear of the vehicle, wherein each phototransistor is electrically connected to the microprocessor means; and

an audible alarm means electrically connected to the microprocessor means for audibly alerting a driver if one of the one or more phototransistor detects an object within a predetermined range of the vehicle,

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

6. The system of claim 5, wherein the object is a trailing vehicle.

7. The system of claim 5, wherein the one or more phototransistors are sensors that operate at 40 Khz modulation so as to reject spurious light.

8. The system of claim 5, wherein the one or more phototransistors are infrared phototransistor detectors.

9. The system of claim 5, wherein at least one of the one or more phototransistors is positioned immediately adjacent the taillight of the vehicle.

10. A method for providing warning to a driver of a vehicle that includes two opposing sides, a steering wheel positioned within a passenger compartment, and a rear, the method being implemented by a computer including one or more processors, the method comprising:

providing a microprocessor means that is mounted within the passenger compartment;

providing one or more phototransistors, each mounted on each side of the vehicle and adjacent the rear of the vehicle, to detect objects within a predetermined range of the vehicle, wherein each phototransistor is electrically connected to the microprocessor means;

providing an audible alarm means to audibly alert a driver if one of the one or more phototransistor detects an object within the predetermined range of the vehicle, wherein the audible alarm means is electrically connected to the microprocessor means; and

providing a turn signal switch means to exclusively activates the audible alarm means if the trailing vehicle is within the predetermined range of the vehicle, wherein the turn signal switch means is electrically connected to the microprocessor means.

11. The method of claim 10, wherein the object is a trailing vehicle.

12. The method of claim 10, wherein the one or more phototransistors are sensors that operate at 40 Khz modulation so as to reject spurious light.

13. The method of claim 10, wherein the one or more phototransistors are infrared phototransistor detectors.

14. The method of claim 10, wherein at least one of the one or more phototransistors is positioned immediately adjacent the taillight of the vehicle.
