Abstract

A communication device for a motor vehicle has a plurality, but preferably two, communication modules that are configured in each case to communicate wirelessly with other motor vehicles and wirelessly with one another. A motor vehicle is equipped with a communication device of this type, and a method for communication between a plurality of motor vehicles is carried out.

Claims

1. A communication device for a motor vehicle, comprising:

a plurality of communication modules to be mounted to the motor vehicle and each configured to communicate wirelessly with other motor vehicles and to communicate wirelessly with one another.

2. The communication device according to claim 1, wherein said plurality of communication modules is exactly two communication modules mounted to the motor vehicle.

3. The communication device according to claim 1, wherein at least one of said communication modules comprises a transmit unit for transmitting data to other motor vehicles, and said at least one communication module is configured to transmit signals at a limited beam angle only.

4. The communication device according to claim 1, wherein each said communication module comprises a transmit unit for transmitting data to other motor vehicles, and wherein each said communication module is configured to transmit signals at a limited beam angle only.

5. The communication device according to claim 1, wherein at least one of said communication modules comprises a receive unit for receiving data from other motor vehicles, and said at least one communication module is configured to receive signals from a limited beam angle only.

6. The communication device according to claim 1, wherein each said communication module comprises a receive unit for receiving data from other motor vehicles, and wherein each said communication module is configured to receive signals from a limited beam angle only.

7. The communication device according to claim 1, wherein a plurality of said communication modules are configured in each case to communicate independently and wirelessly with other motor vehicles and independently and wirelessly directly with one another and/or independently with one another via an on-board power supply system.

8. The communication device according to claim 1, wherein at least two said communication modules are configured to exchange data bidirectionally with one another.

9. The communication device according to claim 8, wherein each of said at least two communication modules has a separate radio unit in order to exchange data wirelessly with the respectively other communication module.

10. The communication device according to claim 1, wherein each said communication module has a dedicated module housing.

11. The communication device according to claim 1, wherein at least one of said communication modules has an interface for connection to a data transmission network.

12. The communication device according to claim 11, wherein the data transmission network is a bus system of a motor vehicle.

13. The communication device according to claim 1, wherein at least one of said communication modules has a man-machine interface configured to assist a vehicle driver in driving the vehicle.

14. The communication device according to claim 1, wherein at least one of said communication modules has a storage unit for electrical energy which is configured to provide sufficient electrical power, at least temporarily, for an operation of said at least one communication module or the communication device.

15. The communication device according to claim 14, wherein each said communication module has a storage unit for electrical energy.

16. The communication device according to claim 1, wherein said communication module comprises an attachment device for attaching the communication module to the motor vehicle.

17. A motor vehicle, comprising a communication device according to claim 1 with at least two communication modules disposed at a spacing distance from one another on or in the motor vehicle.

18. The motor vehicle according to claim 17, wherein a first communication module is configured to communicate with other motor vehicles located in a direction of travel, and a second communication module is configured to communicate with other motor vehicles located opposite the direction of travel.

19. The motor vehicle according to claim 17, wherein each of the communication modules has a limited transmit and/or receive radius and the communication modules are disposed and configured such that a common transmit and/or receive radius of all communication modules together forms an omnidirectional characteristic.

20. A method for communication between a plurality of motor vehicles, the method which comprises:

providing a motor vehicle with a communication device according to claim 1; and

causing the motor vehicle to communicate with other motor vehicles by way of the communication device.
