Abstract

A vehicle-to-X communication module which is configured to transmit operating data to a satellite navigation module. In this way, supply of operating data to the satellite navigation module can be facilitated and, in particular, in many cases reception of the operating data by Assisted GPS (AGPS) can be dispensed with.

Claims

1. A vehicle-to-X communication module for a vehicle, including:

a transceiver configured to exchange data with other vehicles; and

a processor configured to send operating data including at least one of satellite almanac data or satellite ephemeris data to a satellite navigation module that is arranged in the vehicle and configured to compute a position of the vehicle based on the operating data,

wherein the operating data is received by the transceiver from another vehicle when a stored operating data is determined to be invalid.

2. The vehicle-to-X communication module according to claim 1,

which is configured, in response to an impending switching off of the satellite navigation module, to receive and store operating data from the satellite navigation module.

3. The vehicle-to-X communication module according to claim 2,

which is configured, in response to a switching on of the satellite navigation module to send the stored operating data to the satellite navigation module.

4. The vehicle-to-X communication module according to claim 1,

which is configured to receive the operating data in a vehicle-to-X message directly from the other vehicle.

5. The vehicle-to-X communication module according to claim 1,

which is configured to send a message to another vehicle or a plurality of other vehicles, wherein the message contains a request to send operating data to the vehicle.

6. The vehicle-to-X communication module according to claim 5,

which is configured to send the message containing a request to send operating data, in a vehicle-to-X message directly to the other vehicle or the other vehicles.

7. The vehicle-to-X communication module according to claim 1,

which is configured to receive the operating data via a cellular network, by an Assisted GPS (AGPS).

8. The vehicle-to-X communication module according to claim 1,

which is configured to send vehicle speed data and/or vehicle direction of travel data to the satellite navigation module, together with the operating data.

9. The vehicle-to-X communication module according to claim 1,

which is configured to check and/or determine location data of the vehicle as a component of the operating data prior to sending the operating data by comparing these with an environment status and/or by determining a distance to a known object.

10. The vehicle-to-X communication module according to claim 1,

which is configured to send time data as a component of the operating data to the satellite navigation module.

11. The vehicle-to-X communication module according to claim 10,

which is configured to receive the time data from a local time reference or from another vehicle.

12. The vehicle-to-X communication module according to claim 1,

wherein the operating data comprise almanac data and/or ephemerides data.

13. The vehicle-to-X communication module according to claim 4,

which is configured to send a message to another vehicle or a plurality of other vehicles, wherein the message contains a request to send operating data to the vehicle.

14. The vehicle-to-X communication module according claim 4,

which is configured to receive the operating data from another vehicle in response to the stored operating data being found to be invalid;

and/or

which is configured to send the message containing a request to send operating data in response to the stored operating data being found to be invalid.

15. The vehicle-to-X communication module according claim 5,

which is configured to receive the operating data from another vehicle in response to the stored operating data being found to be invalid;

and/or

which is configured to send the message containing a request to send operating data in response to the stored operating data being found to be invalid.

16. The vehicle-to-X communication module according claim 6,

which is configured to receive the operating data from another vehicle in response to the stored operating data being found to be invalid;

and/or

which is configured to send the message containing a request to send operating data in response to the stored operating data being found to be invalid.

17. A vehicle-to-X communication module for a vehicle, including:

a transceiver configured to exchange data with other vehicles; and

a processor configured to;

send operating data to a satellite navigation module that is arranged in the vehicle and compute a position of the vehicle based on the operating data, in response to an impending switching off of the satellite navigation module, receive and store the operating data from the satellite navigation module, in response to a switching on of the satellite navigation module, send the stored operating data to the satellite navigation module, and

in response to a switching on of the satellite navigation module, initially check if the operating data are still valid, on the basis of a time that has elapsed since the switching off, and to only send the operating data to the satellite navigation module if the operating data are still valid.

18. A vehicle-to-X communication module for a vehicle, including:

a transceiver configured to exchange data with other vehicles; and

a processor configured to;

send operating data to a satellite navigation module that is arranged in the vehicle and compute a position of the vehicle based on the operating data, receive the operating data from another vehicle in response to the operating data being found to be invalid, and/or send the message containing a request to send operating data in response to the operating data being found to be invalid.
