Abstract

A method is provided for processing measurement data of a vehicle in order to determine the start of a search for a parking space. The method is characterized in that an estimate of a parking target point is carried out, that an earliest start of a search for a parking space is determined and that a driving analysis is performed between these two points for determining the start of the search for a parking space using map data. Furthermore, a related computer program product is disclosed.

Claims

1. A method for processing measurement data of a vehicle in order to determine a beginning of traffic searching for a parking space, the method comprising the acts of:

estimating a parking destination;

determining an earliest point of beginning to search for a parking space; and

performing journey analysis, using map data, between the estimated parking destination and the determined earliest point of beginning to search for a parking space in order to determine the beginning of the traffic searching for the parking space.

2. The method as claimed in claim 1, wherein the journey analysis involves use of exclusively captured position data and map data.

3. The method as claimed claim 1, wherein a difference between the map data and an airline difference are computed.

4. The method as claimed in claim 1, wherein a relationship of an increase in distance from the parking destination and an interval between successive position data are used as an insufficiency function.

5. The method as claimed in claim 4, wherein a discrete integral is computed over the insufficiency function.

6. The method as claimed in claim 5, wherein the discrete integral is computed only if an error increase has been identified.

7. The method as claimed claim 5, wherein

when a threshold value of the discrete integral is exceeded, traffic searching for a parking space is deemed to have been identified.

8. The method as claimed in claim 5, wherein

the journey analysis considers two threshold values for the discrete integral, and traffic searching for a parking space is deemed to have been identified only if both threshold values are exceeded.

9. The method as claimed in claim 1, wherein

the journey analysis is performed from the earliest point of beginning to search for a parking space in the direction of the parking destination.

10. A computer program product comprising a computer readable medium having stored thereon program code sections that, when executed on a processor, cause the processor to:

estimate a parking destination;

determine an earliest point of beginning to search for a parking space; and

perform journey analysis, using map data, between the estimated parking destination and the determined earliest point of beginning to search for a parking space in order to determine the beginning of the traffic searching for the parking space.
