Abstract

A method for providing data for a driver assistance system of a motor vehicle includes communicating position data concerning a position of the motor vehicle to the driver assistance system, requesting additional information from a server if the driver assistance system requires additional information with respect to the position data, and communicating, in response to the requesting, the additional information from the server to the driver assistance system.

First claim

What is claimed is:

1 . A method for providing data for a driver assistance system of a motor vehicle, comprising:
communicating position data concerning a position of the motor vehicle to the driver assistance system; requesting additional information from a server if the driver assistance system requires additional information with respect to the position data; and communicating, in response to said requesting, the additional information from the server to the driver assistance system.

2 . The method as claimed in claim 1 , wherein said communicating position data is carried out periodically.

3 . The method as claimed in claim 2 , wherein requesting additional information comprises requesting map information of a digital road map, wherein the map information is associated with the position data.

4 . The method as claimed in claim 3 , wherein the map information comprises attributes and/or topological data associated with the position data.

5 . The method as claimed in claim 1 , wherein requesting additional information comprises requesting topological data associated with the position data.

6 . The method as claimed in claim 1 , wherein communicating additional information comprises communicating topological data from map tiles of a digital road map that are associated with the position data.

7 . The method as claimed in claim 5 , wherein requesting additional information further comprises requesting at least one attribute associated with the topological data, and wherein the method further comprises communicating, in response to said requesting additional information, the at least one attribute from the server to the driver assistance system.

8 . The method as claimed in claim 7 , wherein communicating the at least one attribute is carried out in a data format adapted to the attribute.

9 . The method as claimed in claim 8 , wherein the data format comprises a unique identification of the data format and a description of data types contained in the data format.

10 . The method as claimed in claim 7 , wherein the at least one attribute comprises a variable attribute.

11 . The method as claimed in claim 9 , wherein the description of the data types contained in the data format comprises an identification of a variable attribute and a validity duration assigned to the variable attribute.

12 . The method as claimed in claim 9 , further comprising:
informing the driver assistance system about a changed attribute.

13 . The method as claimed in claim 11 , wherein said requesting at least one attribute comprises re-requesting the at least one attribute after a validity duration thereof has expired.

14 . The method as claimed in claim 12 , wherein said requesting at least one attribute comprises re-requesting the at least one attribute after a validity duration thereof has expired.

15 . The method as claimed in claim 1 , wherein communicating, in response to said requesting, the additional information from the server to the driver assistance system comprises communicating between the server and the driver assistance system via a vehicle-internal bus system.

16 . The method as claimed in claim 1 , wherein communicating the position data comprises exclusively communicating the position data, and wherein communicating the additional information comprises exclusively communicating map information.

17 . A system configured to provide data for a driver assistance system of a motor vehicle, comprising:
at least one driver assistance system configured to: receive position data concerning a position of the motor vehicle, and request additional information from a server if additional information with respect to the position data is required.

18 . The system as claimed in claim 17 , further comprising:
a server configured to communicate the additional information to the driver assistance system in response to the request for additional information from the driver assistance system.
