Abstract

A method for communicating between a first motor vehicle and at least one second motor vehicle, belonging to a mobile communication network including at least two motor vehicles. In a first step only one identifying piece of information is exchanged between the vehicles by each driver for forming a communication network by a radio communication unit via radio connection in order to initiate the internal communication of the vehicles present in a column formation, said piece of information being entered in a second step into a network communication unit of each vehicle, in order to join the communication network after acknowledgement by a network communication unit of at least one of the other vehicles belonging to the communication network. The identifying piece of information is an authentication, and the authentication takes place for each vehicle by a randomly generated password.

Claims

1-12. -12. (canceled)

13. A method for communicating between a first motor vehicle and channel usage column drivers closed radiotelephony link first motor vehicle driver drivers first motor vehicle drivers at least one second motor vehicle which belong to a mobile communication network having at least two motor vehicles, comprising:

exchanging only one identity information item between respective vehicles by each driver;

forming a communication network by a radio communication unit via radio connection to initiate internal communication of the vehicles present in a column formation based at least in part on the only one identity information item;

entering the only one identity information item into a network communication unit of each vehicle in order to join the communication network after acknowledgement by the network communication unit of at least one of the other vehicles belonging to the communication network; and

authenticating a respective vehicle by a password generated in accordance with a random-number principle,

wherein the only one identity information is a location information authentication.

14. The method as claimed in claim 13, further comprising:

selective dispatching of messages occurs with a low repetition rate via the radio communication unit available in the respective vehicle after digital map authentication,

wherein the repetition rate is matched to a respective channel usage.

15. The method as claimed in claim 14, wherein the messages contain at least one of a location information item, one GNSS position, and one identity freely selectable by the driver,

wherein the message is encrypted symmetrically.

16. The method as claimed in claim 15,

wherein the location information item is found and displayed on a digital map of a navigation unit of the vehicle as current positions of all vehicles of the communication network.

17. The method as claimed in claim 16, wherein the current positions of the other vehicles relative to a position of one'"'"'s own vehicle are displayed on the digital map.

18. The method as claimed in claim 13, wherein the identity information item exchange between respective drivers of the vehicles of the communication network is carried out via a closed radiotelephony link.

19. The method as claimed in claim 13, wherein the identity information item exchange between drivers of the vehicles of the communication network is carried out via a closed text message link.

20. The method as claimed in claim 13, wherein navigation information items are exchanged between respective network communication units of the vehicles within the communication network.

21. The method as claimed in claim 13, wherein a warning information item is sent to the network communication units of the vehicles if one of the vehicles is affected by a disturbing event with respect to maintaining the column formation.

22. The method as claimed in claim 21, wherein the disturbing event is at least one of:

exceeding a defined maximum distance of a vehicle from the other vehicles;

accident-related stopping of a vehicle;

vehicle defect-related stopping of a vehicle; and

leaving of a planned column route by a vehicle.

23. Method according to claim 22, wherein, in case of the disturbing event occurring, a voice link is established between the vehicles of the column formation.

24. The method as claimed in claim 13, wherein the network communication unit is configured to transmit the messages as one of wireless access and trip authorization unit and based on WLAN.
