Abstract

A method for operating a navigation system of a motor vehicle, wherein upon reception of a destination data record containing a geodetic position and a first address associated with the position. Based on digital map data stored in the navigation system test addresses are created and are geodetically assigned, wherein the test addresses contain at least a street name and are located in the destination region of the position. A second address is selected from the test addresses that with regard to at least one character string describing the test address deviates the least from said first address, wherein, after the level of discrepancy of the second address as compared to the first address is determined to be less than or equal to a maximum value, the navigation system navigates to the second address.

Claims

1. -10. (canceled)

11. Method for operating a navigation system of a motor vehicle, comprising:

receiving a first geodetic position and a first address assigned to the first geodetic position from a destination data record obtained from an Internet source;

determining test addresses accessible to the motor vehicle based on geodetic assignable digital map data available to the navigation system, wherein each of the test addresses comprise at least one street name in a destination region describing geodetic positions;

comparing a character string describing the first address with character strings describing the test addresses;

selecting a second address from the test addresses based on the character string comparisons, wherein the character string describing the second address deviates the least from a character string describing the first address;

determining a level of deviation between the first address and the second address;

comparing the level of deviation against a predetermined threshold; and

operating the navigation system, based on the comparison against the predetermined threshold, by navigating the motor vehicle to the second address.

12. The method according to claim 11, further comprising:

comparing the first geodetic position with the geodetic positions of the test addresses;

selecting a third address of the test addresses when the level of deviation between the first address and the second address exceeds the predetermined threshold, wherein the geodetic position of the third address is spatially closest to the first geodetic position; and

operating the navigation system by navigating to the third address.

13. The method according to claim 11, wherein the destination region is defined by a predetermined dimension around the first geodetic position.

14. The method of claim 13, wherein the predetermined dimension is a range from 50 meters to 300 meters around the first geodetic position.

15. The method according to claim 13, wherein the predetermined dimension is determined based on a number of test addresses found within a test region.

16. The method according to claim 11, further comprising reducing the number of test addresses to one test address located nearest to the geodetic position, when the test address contain street names and additional data, prior to a comparison with the first address based on a redundancy criterion.

17. The method according to claim 11, wherein a Levenshtein measure is used as a level of discrepancy.

18. The method according to claim 11, wherein the address comparison is carried out using the street name.

19. The method according to claim 18, wherein selecting the second address from the test addresses, further comprises:

determining, based on the geodetic assignable digital map data, whether the first address includes a house number;

confirming the house number by comparing the street name of the first address with the street name of the second address; and

selecting the house number of the first address and associating the house number with the second address.

20. The method according to claim 19, further comprising selecting a nearest house number when the first address contains no house number.

21. The method according to claim 11, wherein navigating the motor vehicle to the second address occurs only after a user confirms the address.

22. A motor vehicle comprising:

a navigation system with a control unit, wherein the control unit is configured to;

receive a first geodetic position and a first address assigned to the first geodetic position from a destination data record obtained from an Internet source;

determine test addresses accessible to the motor vehicle based on geodetic assignable digital map data available to the navigation system, wherein each of the test addresses comprise at least one street name in a destination region describing geodetic positions;

compare a character string describing the first address with character strings describing the test addresses;

select a second address from the test addresses based on the character string comparisons, wherein the character string describing the second address deviates the least from a character string describing the first address;

determine a level of deviation between the first address and the second address;

compare the level of deviation against a predetermined threshold; and

operate the navigation system based on the comparison against the predetermined threshold, by navigating the motor vehicle to the second address.

23. The motor vehicle according to claim 22, wherein the control unit is further configured to:

compare the first geodetic position with the geodetic positions of the test addresses;

select a third address of the test addresses when the level of deviation between the first address and the second address exceeds the predetermined threshold, wherein the geodetic position of the third address is spatially closest to the first geodetic position; and

operate the navigation system by navigating to the third address.

24. The motor vehicle according to claim 22, wherein the destination region is defined by a predetermined dimension around the geodetic position.

25. The motor vehicle according to claim 24, wherein the predetermined dimension is a range from 50 meters to 300 meters around the first geodetic position.

26. The motor vehicle according to claim 24, wherein the predetermined dimension is determined based on a number of test addresses found within a test region.
