Abstract

In a method for operating a vehicle, based on a current travel route of the vehicle, a database which includes reference route data assigned to the current travel route is queried as to whether a change in a feature of the current travel route has occurred, and a response of the database that corresponds to the query is made available.

Claims

1-12. -12. (canceled)

13. A method for assisting navigation of a vehicle, comprising:

determining a current travel route of the vehicle;

querying a database, which includes reference route data assigned to the current travel route of the vehicle, whether a change in a feature of the current travel route of the vehicle has occurred; and

outputting, by the database, a response to the query.

14. The method as recited in claim 13, wherein the querying includes transmitting travel route data corresponding to the current travel route of the vehicle to the database, and wherein the response is formed by comparing the transmitted travel route data with the reference route data of the database.

15. The method as recited in claim 14, wherein the database includes an external database which is disposed externally from the vehicle.

16. The method as recited in claim 14, wherein the querying of the database is repeated at predefined time intervals.

17. The method as recited in claim 14, wherein the response to the query includes providing of a warning signal if a change in a feature of the current travel route of the vehicle has occurred.

18. The method as recited in claim 17, wherein the response of the database is outputted when the vehicle is located at a predefined distance preceding the location of the changed feature of the current travel route.

19. The method as recited in claim 18, wherein the response is outputted via at least one of (i) a man-machine interface disposed inside the vehicle, and (ii) a mobile telephone.

20. The method as recited in claim 17, wherein a potential travel route is formed based on consecutive multiple locations of the vehicle ascertained over time, and wherein the potential travel route is used as the current travel route for the querying of the database.

21. The method as recited in claim 20, wherein the potential travel route is compared to multiple standard travel routes, and wherein the potential travel route is used as the current travel route for the querying of the database only if a predefined agreement exists between the potential travel route and one of the multiple standard travel routes.

22. A system for assisting navigation of a vehicle, comprising:

a database containing reference route data;

a database interrogator configured to (i) ascertain a current travel route of the vehicle, and (ii) query the database whether a change in a feature of the current travel route of the vehicle has occurred; and

a furnishing device which furnishes a response of the database to the query;

wherein a potential travel route is formed based on consecutive multiple locations of the vehicle ascertained over time, and the potential travel route is used as the current travel route for the querying of the database, and wherein the querying includes transmitting travel route data corresponding to the current travel route of the vehicle to the database, and wherein the response is formed by comparing the transmitted travel route data with the reference route data of the database.

23. A non-transitory, computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, performs a method for operating a vehicle, the method comprising:

determining a current travel route of the vehicle;

querying a database, which includes reference route data assigned to the current travel route of the vehicle, whether a change in a feature of the current travel route of the vehicle has occurred; and

outputting, by the database, a response to the query;

wherein a potential travel route is formed based on consecutive multiple locations of the vehicle ascertained over time, and the potential travel route is used as the current travel route for the querying of the database, and wherein the querying includes transmitting travel route data corresponding to the current travel route of the vehicle to the database, and wherein the response is formed by comparing the transmitted travel route data with the reference route data of the database.
