Abstract

An inter-vehicle communication system provides the ability to propagate signal groups along lanes of traffic and between lanes of traffic. Each vehicle includes a user interface that permits the driver of vehicle to send messages and to receive messages, the messages generally referring to traffic conditions. In this manner, drivers in traffic pattern can be made aware of traffic conditions that are remote from the vehicle and can take appropriate, timely action.

Claims

1. A vehicle communication system, the system comprising:

a first signal receiving unit receiving signals applied to the front of a vehicle;

a first signal generating unit generating signals at the rear of the vehicle, the first signal receiving unit coupled to the first signal generating unit, the first signal generating unit and first signal receiving unit transmitting a data signal received by the front of the vehicle to the rear of the vehicle for transmission.

2. The system as recited in claim 1 further comprising:

a second signal receiving unit receiving signals at the rear of the vehicle;

a second signal generating unit generating signals from the front of the vehicle, the second signal receiving unit coupled to the second signal generating unit, the second signal generating unit and second signal receiving unit transmitting a data signal received at the rear of the vehicle from front of the vehicle.

3. The system as recited in claim 1 further comprising an interface unit, wherein the first and the second signal receiving unit and the first and second signal generating unit are coupled to the interface unit.

4. The system of claim 3 wherein the interface unit can receive signals for transmission from at least one of a user or a vehicle component.

5. The system of claim 3 wherein the user interface unit provides a vehicle user with information about traffic conditions.

6. The system as recited in claim 2 further comprising a third and fourth signal receiving unit and a third and fourth signal generating unit coupled respectively to the receiving unit for transmitting signals to vehicles traveling parallel to the vehicle with the components.

7. A vehicle inter-communication system for communication between vehicles, the system comprising:

a plurality of vehicles, each vehicle including;

a first transmission unit, the first transmission unit receiving signals directed at a front of a vehicle and transmitting the signals directed away from the rear of the vehicle;

a second transmission unit, the second transmission unit receiving signals directed at the rear of the vehicle and transmitting signals directed away from the front of the vehicle; and

an interface coupled to the first and second transmission unit, the interface unit communicating to a user of the vehicle the information contained in the signals.

8. The system as recited in claim 7 further comprising:

a third transmission unit, the third transmission unit receiving signals on a first side of the vehicle and transmitting signals on a second side of the vehicle, and

a fourth transmission unit for receiving signals on the second side of the vehicle and transmitting signals from the first side of the vehicle.

9. The system as recited in claim 7 wherein the information is traffic information.

10. The system as recited in claim 7 wherein the interface unit receives information for transmission from at least one of the vehicle user and vehicle components.

11. The system as recited in claim 7 wherein the interface unit removes redundant information from the inter-vehicle communication system.

12. A method of communication between vehicles, the method comprising;

receiving status signals from a vehicle in front of a user vehicle;

transmitting the status signals to a vehicle behind user vehicle;

in response to preselected status signals, identifying a situation causing the status signals to the user.

13. The method as recited in claim 12 further comprising;

receiving status signals from a vehicle in the rear of the user vehicle; and

transmitting the status signals to a vehicle in front of the user vehicle.

14. The method as recited in claim 12 further comprising transmitting the status signals to and from vehicles traveling in a different lane in a direction parallel to the user vehicle.

15. The method as recited in claim 12 further comprising generating status signals in the user vehicle by a user input.

16. The method as recited in claim 12 further comprising generating status signals in the user vehicle in response to preselected user vehicle conditions.
