Abstract

System and method for conveying data between vehicles includes a data generating system arranged on a first vehicle to obtain or generate information about the first vehicle or conditions around the first vehicle, a first communications system arranged on the first vehicle and coupled to the data generating system for communicating with a wireless Internet service provider (ISP) and a second communications system arranged on a second vehicle and communicating with an ISP. The first communications system enables the information obtained or generated by the data generating system to be transmitted via the Internet to the second communications system. The first and second communications systems can communicate with the same ISP or different ISPs linked to one another.

Claims

1. A system for conveying data between vehicles, comprising:

a data generating system arranged on a first vehicle to obtain or generate information about the first vehicle or conditions around the first vehicle;

a first communications system arranged on the first vehicle and coupled to said data generating system for communicating with a wireless Internet service provider (ISP); and

a second communications system arranged on a second vehicle and communicating with a wireless Internet service provider (ISP),

said first communications system being arranged to enable the information obtained or generated by said data generating system to be transmitted via the Internet to said second communications system.

2. The system of claim 1, wherein said data generating system is arranged to obtain or generate information about at least one of a travel direction, a destination, occupancy, a road on which the first vehicle is traveling, road maps in the vicinity of the first vehicle, environmental conditions around the first vehicle, traffic in the vicinity of the first vehicle, and construction in the vicinity of the first vehicle.

3. The system of claim 1, wherein said first communications system is arranged to establish an Internet link to said second communications system via at least one ISP without manual intervention.

4. The system of claim 1, further comprising a first vehicle position and movement determining system arranged in the first vehicle for determining the position and movement of the first vehicle, said first communications system being coupled to said first position and movement determining system and arranged to transmit the determined position and movement of the first vehicle via the Internet to said second communications system in conjunction with additional information obtained or generated by said data generating system about the conditions around the first vehicle.

5. The system of claim 4, further comprising:

a second position and movement determining system arranged in the second vehicle for determining the position and movement of the second vehicle; and

a processor in the second vehicle for considering the positions and movements of the first and second vehicle and being arranged to react to the information obtained or generated by said data generating system in the first vehicle based on analysis of the relative positions and movements of the first and second vehicles.

6. The system of claim 5, further comprising:

a data storage facility coupled to the ISP for storing the information obtained or generated by said data generating system in association with the position of the first vehicle when that information is communicated from said first communications system such that said data storage facility contains data about conditions of an area traveled by the first vehicle in association with the location of that area;

said second communications system being arranged to communicate with said data storage facility via the ISP to determine whether said data storage facility contains information about an area about to be or being traveled by the second vehicle and if so, to request such information.

7. The system of claim 4, further comprising a reactive system arranged in the second vehicle to react to the information obtained or generated by said data generating system.

8. The system of claim 4, further comprising a notification system arranged in the second vehicle for visually or audibly notifying an occupant of the second vehicle about the information obtained or generated by said data generating system

9. The system of claim 1, wherein said first communications system is arranged to transmit information about a type of the first vehicle to said second communications system in conjunction with the information obtained or generated by said data generating system.

10. The system of claim 1, further comprising a traffic monitoring facility also arranged to receive the information obtained or generated by said data generating system, said traffic monitoring facility being arranged to analyze the information and generate traffic reports based thereon, perform traffic control actions, and/or notify additional vehicles about the information.

11. The system of claim 10, further comprising a position determining system arranged in the first vehicle for determining the position of the first vehicle, said first communications system being coupled to said position determining system and arranged to transmit the determined position of the first vehicle via the Internet to said traffic monitoring facility in conjunction with additional information obtained or generated by said data generating system about the conditions around the first vehicle, said traffic monitoring facility being arranged to set speed limits for an area including the position from which the first vehicle obtained or generated the information and which speed limits are based on the obtained or generated information, and convey the speed limits to signs on or alongside roads in that area.

12. A method for conveying data between vehicles, comprising:

obtaining or generating information at a first vehicle about the first vehicle or conditions around the first vehicle;

transmitting the obtained or generated information from the first vehicle to a wireless Internet service provider (ISP); and

transmitting the obtained or generated information from an ISP to a second vehicle.

establishing communications between the second vehicle and the ISP to enable the second vehicle to determine whether the database contains information about an area about to be or being traveled by the second vehicle; and

if so, transmitting the information from the database to the second vehicle such that the second vehicle receives information previously provided to the database by the first vehicle.

18. The method of claim 12, further comprising visually or audibly notifying an occupant of the second vehicle about the information transmitted from the first vehicle

19. The method of claim 12, further comprising transmitting information about a type of the first vehicle to the second vehicle.
