Abstract

A method is described for updating a digital map for vehicle navigation. The method includes a step of determining an adjustment signal for adjusting a detection range of an environment sensor of a vehicle to a section of an environment of the vehicle that corresponds to an area of the digital map to be updated, using an item of information about the area to be updated, and the method including a step of supplying area data for updating the digital map, the area data representing an image of the section of the environment detected by the environment sensor.

Claims

1-10. -10. (canceled)

11. A method for updating a digital map for vehicle navigation, comprising:

determining an adjustment signal for adjusting a detection range of an environment sensor of a vehicle to a section of an environment of the vehicle that corresponds to an area of

the digital map to be updated, by using an item of information about the area to be updated; and

supplying area data for updating the digital map, the area data representing an image of the section of the environment detected by the environment sensor.

12. The method as recited in claim 11, further comprising reading in an update signal that includes the item of information about the area of the digital map to be updated, via an interface to a vehicle-external management device for managing the digital map, wherein the area data are made available in the update signal to the interface to the vehicle-external management device in the step of supplying.

13. The method as recited in claim 11, further comprising selecting the environment sensor using the item of information about the area to be updated.

14. The method as recited in claim 11, further comprising checking a use of the environment sensor by a driver-assistance system, wherein the step of determining the adjustment signal is carried out as a function of a result of the step of checking.

15. The method as recited in claim 11, wherein the step of determining determines the adjustment signal in order to adjust an opening angle of the environment sensor.

16. The method as recited in claim 11, wherein the step of determining the adjustment signal is carried out using a position signal that indicates a position and an orientation of the vehicle.

17. The method as recited in claim 11, further comprising detecting the area data using the environment sensor.

18. A device for updating a digital map for vehicle navigation, comprising:

an arrangement for determining an adjustment signal for adjusting a detection range of an environment sensor of a vehicle to a section of an environment of the vehicle that corresponds to an area of the digital map to be updated, by using an item of information about the area to be updated; and

an arrangement for supplying area data for updating the digital map, the area data representing an image of the section of the environment detected by the environment sensor.

19. A computer program for carrying out a method for updating a digital map for vehicle navigation, the method comprising:

determining an adjustment signal for adjusting a detection range of an environment sensor of a vehicle to a section of an environment of the vehicle that corresponds to an area of the digital map to be updated, by using an item of information about the area to be updated; and

supplying area data for updating the digital map, the area data representing an image of the section of the environment detected by the environment sensor.

20. A machine-readable memory medium on which a computer program is stored for carrying out a method for updating a digital map for vehicle navigation, the method comprising:

determining an adjustment signal for adjusting a detection range of an environment sensor of a vehicle to a section of an environment of the vehicle that corresponds to an area of the digital map to be updated, by using an item of information about the area to be updated; and

supplying area data for updating the digital map, the area data representing an image of the section of the environment detected by the environment sensor.
