Abstract

A system to enable the operator of a vehicle to view road and traffic conditions straight ahead, while simultaneously viewing road and traffic conditions behind the vehicle to achieve safe, strain-free vehicle operation. The system comprises: a plurality of compact video cameras (1, 2 and 3) utilizing CCD video imaging devices; positioned for wide angle viewing of front and rear traffic conditions. The output from the CCD devices are controlled and processed by a computer (6) containing an interactive CD-ROM disc and drive device (7). The images output by the personal computer are displayed on a horizontally extended display (5), positioned just above the surface of a dashboard of the vehicle. Safety margins are calculated and established by the interactive computer system and vocal warning is issued by the computer when the safety margins on the displays are exceeded.

Claims

1. A mobile, multi-media workstation system for a vehicle comprising:

a plurality of video cameras driven with a common time base to produce synchronized video signals;

said plurality of video cameras being mounted for wide angle simultaneously viewing of traffic and travel conditions forwardly and rearwardly of a vehicle;

a horizontally elongated LCD video display device mounted above a dashboard of said vehicle and equipped with signal processing hardware to simultaneously display a plurality of video images of said synchronized video signals;

a personal computer connected between said plurality of video cameras and said horizontally elongated LCD video display device, to provide interactive control;

a program inputting EE-PROM card device, and a video/audio data inputting and recording CD-ROM device connected to said personal computer, enabling signal processing and interactive system control by said personal computer;

a directional microphone connected to said personal computer for inputting voice commands issued by an operator of the vehicle to control said mobile, multi-media workstation system; and

a speaker system comprised of at least one speaker located close to the operator, at ear level, connected to said personal computer to provide voice messages and warnings output by said personal computer in response to programmed criteria.

2. The workstation of claim 1, further including a plurality of sensors connected to said personal computer for monitoring the vehicle travel and running conditions, local and global position and weather conditions, emergency traffic conditions, and to provide data that is processed, edited and stored in realtime by said personal computer.

3. The workstation of claim 2 wherein a vocal warning is output from a coherent sound producing speaker system connected to said personal computer and located at ear level in close proximity to the operator, when predetermined criteria are sensed by either the video cameras or said plurality of sensors.

4. The workstation of claim 3 wherein recorded data in said personal computer can be read out and further processed to provide comparison data that is edited into interactive visual or vocal messages and commands issued to said operator through said coherent sound producing speaker system.

5. The workstation of claim 1 wherein recorded data in said personal computer can be read out and further processed to provide comparison data that is edited into interactive visual or vocal messages and commands issued to said operator through said speaker system.

6. The workstation of claim 5 wherein said speaker system is a coherent sound producing speaker system located at ear level in close proximity to the operator, and said coherent sound producing system outputs a vocal warning when predetermined criteria are sensed by said plurality of video cameras.

7. The workstation of claim 1 wherein said speaker system is a coherent sound producing speaker system located at ear level in close proximity to the operator, and said coherent sound producing speaker system outputs a vocal warning when predetermined criteria are sensed by either said plurality of video cameras or a plurality of sensors connected to said personal computer.

8. The workstation of claim 1 wherein there are three video camera;

a first of said three video cameras facing forwardly of a vehicle; and

a second and third of said three video cameras facing rearwardly of a vehicle.

9. A navigation system for a vehicle comprising:

three video imaging means driven with a common time base to produce synchronized video images;

said three video imaging means being mounted for wide angle simultaneous viewing of traffic forwardly and rearwardly of the direction of travel of said vehicle;

a video display means mounted above a dashboard of said vehicle;

said video display means having signal processing means to simultaneously display said synchronized video images;

computer means interconnected between said plurality of video imaging means and said video display means to provide interactive control thereof;

a program inputting means connected to said computer means, to enable said computer means to process received signals and interactively control said navigation system;

a directional microphone means connected to said computer means for inputting voice commands; and

a speaker system directed towards an operator of said vehicle to provide audio output from said computer means.

10. The navigation system of claim 9 wherein a first of said three video cameras faces forwardly in said vehicle;

and a second and third of said three video cameras faces rearwardly in said vehicle.

11. The navigation system of claim 10, further including a plurality of external sensors connected to said computer means for monitoring vehicle travel and running conditions, local and global position and weather conditions, emergency traffic conditions, and to provide data that is processed, edited and stored in real-time by said computer means.

12. A vehicle having a multi-media workstation system comprising:

a plurality of video cameras driven with a common time base to produce synchronized video signals, mounted for wide angle simultaneous viewing of traffic and travel conditions forwardly and rearwardly of said vehicle;

a horizontally elongated LCD video display device mounted above a dashboard of the vehicle and equipped with signal processing hardware to simultaneously display a plurality of video images of said synchronized video signals;

a personal computer connected between said plurality of video cameras and said LCD video display device, to provide interactive control of said multi-media workstation system;

a program inputting EE-PROM card device, and a video/audio data inputting and recording CD-ROM device, connected to said personal computer and enabling signal processing and interactive multi-media workstation system control by said personal computer;

a directional microphone connected to said personal computer for inputting voice commands issued by an operator of said vehicle to control said multi-media workstation system; and

a coherent sound producing speaker system comprised of at least two speakers connected to said personal computer and located close to said operator, at ear level, to provide audio output from said personal computer in response to sensing of programmed criteria.

13. The system of claim 12, further including a plurality of sensors connected to said personal computer for monitoring said vehicle travel and running conditions, local and global position and weather conditions, and emergency traffic conditions;

said plurality of sensors inputting data that is processed, edited and stored in realtime by said personal computer.

14. The system of claim 12 wherein there are three video cameras;

a first of said three video cameras being mounted in said vehicle so as to face forwardly thereof; and

a second and third of said three video cameras being mounted in said vehicle so as to face rearwardly thereof.
