Communication system, method of communication between and among vehicles and vehicle comprising such a communication system
First Claim
1. A system of communication among moving vehicles by means of a wireless network, the system comprising:
- a direction determining unit that uses a moving direction of a first vehicle to assign a first direction code to a first message, wherein the first direction code classifies the moving direction of the first vehicle into one direction area of at least four possible direction areas;
a selection unit connected to the direction determining unit that selects a communication channel based upon the first direction code;
a plurality of directional antennas that broadcast the first message with the first direction code from the first vehicle to a second vehicle and receive a second message over the selected communication channel with a second direction code sent from the second vehicle to the first vehicle, wherein the plurality of directional antennas ignore the second message when the second direction code does not match the direction code currently assigned to the first message.

Abstract
In order to provide a communication system as well as a vehicle comprising such a communication system for communication between and among vehicles and a method for communication between and among vehicles moving in any different directions within the same area by means of at least one channel designed for transmitting at least one message, the channel comprising at least one code for communication of the vehicles within at least one cluster in which at least one group of vehicles are clustered, wherein interference is to be eliminated, the vehicle comprises directional antennas oriented in different directions in relation to the moving direction of the vehicle to enable the sending direction of the message to be allocatable to directions in relation to the moving direction of the vehicle and the channel is assigned to direction areas, north, east, south and west.

5. A method of communication among moving vehicles in a wireless network, the method comprising:
-
assigning a first direction code to a first message based upon a moving direction of a first vehicle, wherein the first direction code classifies the moving direction of the first vehicle into one direction area of at least four possible direction areas; selecting a communication channel based upon the first direction code; broadcasting the first message with the first direction code from a plurality of directional antennas in the first vehicle to a second vehicle over the selected communication channel; and receiving a second message with a second direction code sent from the second vehicle to the first vehicle, wherein the plurality of directional antennas ignore the second message when the second direction code does not match the direction code currently assigned to the first message. - View Dependent Claims (6, 7, 8, 9, 10, 16, 18, 20)
