Abstract

A vehicle video display verification system, comprising a camera carried by the vehicle; a display unit positioned in the vehicle displaying images captured by said camera; a verification sensor monitoring the status of image information from said camera being displayed on said display unit; and, a video control unit receiving said image information from said camera and outputting said image information to said display unit, and receiving feedback information from said verification sensor; wherein said video control unit records said image information from said camera and said feedback information from said verification sensor for establishing confirmation of an image display status on said display unit in the event of a vehicle accident.

Claims

1. A vehicle video display verification system, comprising:

a camera carried by the vehicle;

a display unit positioned in the vehicle displaying images captured by said camera;

a verification sensor monitoring the status of image information from said camera being displayed on said display unit; and

,

a video control unit receiving said image information from said camera and outputting said image information to said display unit, and receiving feedback information from said verification sensor;

wherein said video control unit records and saves said image information from said camera and said feedback information from said verification sensor for establishing confirmation of an image display status on said display unit in the event of a vehicle accident.

2. The system of claim 1, wherein said verification sensor comprises a secondary camera positioned within the vehicle capturing an image of said display unit in operation.

3. The system of claim 1, wherein said verification sensor is included in said display unit and is configured to determine an on/off status of a display panel of said display unit.

4. The system of claim 1, wherein said verification sensor comprises an electrical current sensor configured to determine the flow of electrical current along electrical wire transmitting said image information from said camera to said display unit.

5. The system of claim 1, wherein said verification sensor comprises a light sensor mounted in front of said display unit and configured to determine the output of light from said display unit.

6. The system of claim 1, wherein said video control unit is configured to continuously receive and continuously record said image information from said camera and said feedback information from said verification sensor.

7. The system of claim 6, wherein said video control unit is further configured to receive and record vehicle status information from at least one vehicle sensor to determine if a vehicle crash event has occurred.

8. The system of claim 7, wherein said video control unit is in electronic communication with the vehicle CAN bus for receiving said vehicle status information.

9. The system of claim 7, wherein said at least one vehicle sensor includes an impact sensor in electronic communication with said video control unit.

10. The system of claim 7, wherein said at least one vehicle sensor includes an accelerometer in electronic communication with said video control unit.

11. The system of claim 7, wherein said video control unit is further configured to save the recorded said image information, said feedback information and said vehicle status information on a storage media for a predetermined time period before and after determination of said vehicle crash event in a manner to prevent overwriting of the saved information.

12. The system of claim 11, wherein said storage media includes a flash memory card removably carried by said video control unit.

13. The system of claim 11, including a manual trigger switch in electronic communication with said video control unit, wherein said video control unit is further configured to save the recorded said image information, said feedback information and said vehicle status information on said storage media for a predetermined time period before and after actuation of said manual trigger switch.

14. The system of claim 1, including a battery backup power supply operatively associated with said video control unit for continued operation of said video control unit when vehicle power is lost.

15. A vehicle video display verification system, comprising:

a camera carried by the vehicle capturing images of an exterior area around the vehicle and transmitting image information;

a display unit positioned in the vehicle displaying said image information captured by said camera;

a video control unit configured to receive and process said image information from said camera and output the processed said image information to said display unit so that said image information is provided to said display unit in a format capable of display by said display unit;

a secondary camera carried by the vehicle being positioned to capture images of said display unit displaying image information from said camera, wherein said images captured by said secondary camera define feedback information transmitted to said video control unit;

a vehicle sensor in electronic communication with said video control unit, wherein said vehicle sensor is configured to determine a change in vehicle status and transmit vehicle status information;

wherein said video control unit is further configured to determine when a vehicle crash event has occurred based on said vehicle status information from said vehicle sensor; and

,

wherein said video control unit is further configured to record said image information, said feedback information, and said vehicle status information; and

,

wherein said video control unit is further configured to save the recorded said image information, said feedback information, and said vehicle status information on a storage media operatively associated with said video control unit for a predetermined time period both before and after determination of said vehicle crash event.

16. A vehicle video display verification system, comprising:

a camera;

a display unit displaying images captured by said camera;

a video control unit operatively associated with said camera and said display unit, wherein said video control unit is configured to receive and transmit image information from said camera to said display unit;

a verification sensor configured to monitor the display of images by said display unit and transmit feedback information to said video control unit; and

,

a vehicle sensor transmitting vehicle status information to said video control unit;

wherein said video control unit is further configured to record said image information, said feedback information, and said vehicle status information; and

,

wherein said video control unit is further configured to determine a vehicle crash event based on said vehicle status information; and

,

wherein said video control unit is further configured to save the recorded said image information, said feedback information, and said vehicle status information on a storage media for a predetermined time period both before and after determination of said vehicle crash event.

17. The system of claim 16, wherein said vehicle sensor is selected from the group consisting of an impact sensor, an accelerometer, an airbag sensor and combinations thereof.

18. The system of claim 16, wherein said video control unit is in electronic communication with the vehicle CAN bus for receiving said vehicle status information.

19. The system of claim 16, wherein said storage media includes a flash memory card removably carried by said video control unit.

20. The system of claim 16, including a manual trigger switch in electronic communication with said video control unit, wherein said video control unit is further configured to save the recorded said image information, said feedback information and said vehicle status information on said storage media for a predetermined time period before and after actuation of said manual trigger switch.
