Abstract

A method for transferring data from an image-data-based map service for use in an assistance system of a vehicle includes the following: ascertaining the position and/or orientation of the vehicle, retrieving image data of the vehicle surroundings from the image-data-based map service, extracting items of information from the image data of the map service, and transferring the items of information into the assistance system.

First claim

What is claimed is:

1. A method for the transfer of data from an image-data-based map service for use in an assistance system of a vehicle, comprising:
ascertaining at least one of: i) a position of the vehicle and ii) an orientation of the vehicle;
retrieving image data of the vehicle surroundings from the image-data-based map service;
extracting items of information from the image data of the map service; and
transferring the items of information into the assistance system,
wherein the ascertaining includes ascertaining the position of the vehicle, wherein during the ascertaining of the position of the vehicle, a comparison of camera images of the vehicle surroundings to the image-data-based map service is carried out, and
wherein the position of the vehicle and at least one of the camera images and the surroundings data are compared to the image data of the map service, and the image data of the map service are updated in the event of recognized changes.

2. The method as recited in claim 1 , wherein the image data of the map service are supplemented by camera images of the vehicle surroundings.

3. The method as recited in claim 1 , wherein the image data of the map service are supplemented by surroundings data detected using surroundings sensors.

4. The method as recited in claim 3 , wherein the image data of the map service are supplemented by camera images of the vehicle surroundings.

5. The method as recited in claim 3 , wherein surround sensors include at least one of: an ultrasound sensor, a lidar sensor, and a radar sensor.

6. The method as recited in claim 1 , wherein parking spaces in the surroundings of the vehicle are ascertained from the image data of the map service.

7. The method as recited in claim 6 , wherein the parking spaces in the surroundings of the vehicle are ascertained from camera images of the vehicle surroundings.

8. The method as recited in claim 1 , wherein at least one of traffic signs relating to no stopping and no parking zones, location of an obstruction, including trees, a location and height of a curb, and type and location of an intersection, are ascertained and analyzed in the image data.

9. The method as recited in claim 1 , wherein at least one of traffic signs relating to no stopping and no parking zones, location of an obstruction, including trees, a location and height of a curb, and type and location of an intersection, are ascertained and analyzed in the image data and the camera images.

10. The method as recited in claim 1 , wherein at least one of traffic signs relating to no stopping and no parking zones, location of an obstruction, including trees, a location and height of a curb, and type and location of an intersection, are ascertained and analyzed in the image data and the surroundings data.

11. The method as recited in claim 1 , wherein data of at least one of a radio-based navigation system and a satellite-based navigation system are considered during the ascertainment of the position of the vehicle.

12. The method as recited in claim 1 , wherein the image data of the map service are updated only if the change recognized by comparison has been recognized at least twice.

13. The method as recited in claim 12 , wherein each recognition of a change is independent of another recognition of the change.

14. The method as recited in claim 1 , wherein an image, which is displayed to the driver, is prepared from the image data of the map service and the camera images and the surroundings data and from items of information obtained therefrom, an image display being designed as a bird-s eye view or 3-D view and the display containing items of information about possible parking spaces in the surroundings of the vehicle.

15. The method as recited in claim 14 , wherein the image display is designed so it may be increased and decreased in size, and if the image display is decreased in size, a seamless transition to a display exclusively produced from image data of the map service takes place.

16. The method as recited in claim 1 , wherein the extracted items of information inform the driver about at least one of speed limits and pedestrian crossings.

17. A computer-readable storage medium storing a computer program for the transfer of data from an image-based map service for use in an assistance system of a vehicle, the computer program when executed by a computer, causing the computer to perform:
ascertaining at least one of: i) a position of the vehicle and ii) an orientation of the vehicle,
retrieving image data of the vehicle surroundings from the image-data-based map service:
extracting items of information from the image data of the map service; and
transferring the items of information into the assistance system,
wherein the ascertaining includes ascertaining the position of the vehicle, wherein during the ascertaining of the position of the vehicle, a comparison of camera images of the vehicle surroundings to the image-data-based map service is carried out, and
wherein the position of the vehicle and at least one of the camera images and the surroundings data are compared to the image data of the map service, and the image data of the map service are updated in the event of recognized changes.

18. A device for the transfer of data from an image-based map service for an assistance system of a vehicle, the device comprising a control unit configured to ascertain at least one of: i) a position of the vehicle and ii) an orientation of the vehicle, retrieve image data of the vehicle surroundings from the image-data-based map service, extract items of information from the image data of the map service, and transfer the items of information into the assistance system,
wherein the ascertaining includes ascertaining the position of the vehicle, wherein during the ascertaining of the position of the vehicle, a comparison of camera images of the vehicle surroundings to the image-data-based map service is carried out, and
wherein the position of the vehicle and at least one of the camera images and the surroundings data are compared to the image data of the map service, and the image data of the map service are updated in the event of recognized changes.
