Abstract

A method for providing map data in a first transportation vehicle wherein position data is detected by second transportation vehicles concerning people detected by the second transportation vehicles in a surrounding area of the respective second transportation vehicles and is transmitted to a central data-processing unit so that at least one route which is at least partly used by at least some of the people is specified by the central data processing unit based on the aggregated position data and that route data of the specified at least one route is provided as part of the map data in the first transportation vehicle.

First claim

The invention claimed is:

1. A transportation vehicle that is configured to detect people in an area surrounding the transportation vehicle and to specify position data of the detected people, wherein the transportation vehicle transmits the specified position data to a central data-processing unit and receives route data for at least one route from the central data-processing unit, wherein the route data is specified based on aggregated position data of the transportation vehicle and/or of second transportation vehicles, wherein the route data is at least partly used by people as part of map data,
wherein, based on the aggregated position data, a review is performed whether at least one stop point is located on the specified route, and, in response to the at least one stop point being located on the specified route, a position of the stop point is provided to the first transportation vehicle as part of the route data, and
wherein, based on the specified position data, movement data of the people are determined and the at least one stop point is specified based on the movement data.

2. The transportation vehicle of claim 1 , wherein the people are pedestrians and/or cyclists.

3. The transportation vehicle of claim 1 , wherein the second transportation vehicles detect the people in respective surrounding areas by at least one environment sensor.

4. The transportation vehicle of claim 1 , wherein the second transportation vehicles repeatedly detect the position data of the people for as long as the respective people are located in respective detection areas of the respective second transportation vehicles.

5. The transportation vehicle of claim 1 , wherein, to detect at least one of the people through at least one of the second transportation vehicles, an object in the surrounding area of the second transportation vehicle is detected, and the detected object is classified as a person or at least as being related to a person.

6. The transportation vehicle of claim 1 , wherein a first position of the detected person relative to the second transportation vehicle is specified to provide the position data concerning the at least one of the detected people through at least one of the second transportation vehicles, and a second position of the second transportation vehicle is specified, and the position data are determined based on the first position and the second position.

7. The transportation vehicle of claim 1 , wherein at least one driver assistance function of the first transportation vehicle is carried out based on the route data provided.

8. A central data processing unit for providing map data in a first transportation vehicle, wherein the central data processing unit:
receives position data detected by a plurality of second transportation vehicles concerning people detected by the second transportation vehicles in a surrounding area of the respective second transportation vehicles;
aggregates the received position data and specifies at least one route which was at least partly used by at least some of the people based on the aggregated position data; and
provides route data of the specified at least one route as part of the map data in the first transportation vehicle,
wherein, based on the aggregated position data, a review is performed whether at least one stop point is located on the specified route, and, in response to the at least one stop point being located on the specified route, a position of the stop point is provided to the first transportation vehicle as part of the route data.

9. A method for providing map data in a first transportation vehicle, the method comprising:
transmitting position data detected by a plurality of second transportation vehicles concerning people detected by the second transportation vehicles in a surrounding area of the respective second transportation vehicles to a central data-processing unit;
specifying at least one route at least partly used by at least some of the people by the central data-processing unit based on the aggregated position data; and
providing route data of the specified at least one route as part of the map data in the first transportation vehicle,
wherein, based on the aggregated position data, a review is performed whether at least one stop point is located on the specified route, and, in response to the at least one stop point being located on the specified route, a position of the stop point is provided to the first transportation vehicle as part of the route data.

10. The method of claim 9 , wherein the people are pedestrians and/or cyclists.

11. The method of claim 9 , wherein the second transportation vehicles detect the people in the respective surrounding areas by at least one environment sensor.

12. The method of claim 9 , wherein the second transportation vehicles repeatedly detect the position data of the people for as long as the respective people are located in a specific detection area of the respective second transportation vehicles.

13. The method of claim 9 , wherein, to detect at least one of the people through at least one of the second transportation vehicles, an object in the surrounding area of the second transportation vehicle is detected, and the detected object is classified as a person or at least as being related to a person.

14. The method of claim 9 , wherein a first position of the detected person relative to the second transportation vehicle is specified to provide the position data concerning the at least one of the detected people through at least one of the second transportation vehicles, and a second position of the second transportation vehicle is specified, and the position data are determined based on the first position and the second position.

15. The method of claim 9 , wherein at least one driver assistance function of the first transportation vehicle is carried out based on the route data provided.
