Abstract

A method of receiving messages which are transmitted from vehicle to vehicle and contain information relating to traffic is characterized in that information from received messages is only accepted when a number of identical items of information are received, wherein the number is greater in heavy traffic than in light traffic.

Claims

1. A method of receiving messages transmitted from vehicle to vehicle and containing information relating to traffic, characterized in that information from received messages is only accepted when a number of identical items of information are received, wherein the number is greater in heavy traffic than in light traffic.

2. A method as claimed in claim 1, characterized in that the traffic density is measured by sensors on the vehicle in which the messages are received.

3. A method as claimed in claim 1, characterized in that the traffic density is obtained from a stationary information system.

4. A method as claimed in claim 1, characterized in that the number depends on further variables.

5. A method as claimed in claim 4, characterized in that the further variables include at least weather and road condition information.

6. A method as claimed in claim 1, characterized in that the number depends on weighting of the respective information.

7. A method as claimed in claim 6, characterized in that information about the road network is used for weighting.

8. A method as claimed in claim 6, characterized in that the user'"'"'s individual data are used for weighting.

9. A method as claimed in claim 6, characterized in that measured data are used for weighting, which are obtained by means of vehicle sensors.

10. A method as claimed in claim 1, characterized in that the information which is accepted is displayed.

11. A method as claimed in claim 1, characterized in that the information which is accepted brings about intervention in the vehicle control system.
