Method for processing measurement data of a vehicle in order to determine the start of a search for a parking space and computer program product
First Claim
1. A method for generating a parking-space-search-traffic data object identifying the start of a search for a parking space, wherein the method comprises:
- generating, via a global positioning system unit, drive position data corresponding to a sequence of positions of the vehicle from a pre-end position along an actually driven path to an end position;
identifying, via a processor, the pre-end position as inefficient by determining, from the drive position data, an inefficiency value for the pre-end position, wherein the inefficiency value is determined by comparing a cumulative distance to the end position with a linear distance to the end position, wherein the cumulative distance is the sum of straight-line distances between each successive position from the pre-end position to the end position, and the linear distance is the straight-line distance between the pre-end position and the end position;
verifying, via the processor, the pre-end position as inefficient by comparing the cumulative distance with a route distance, the route distance being the distance of an efficient driving route from the pre-end position to the end position, as determined by a navigation unit;
generating, via the processor, the parking-space-search-traffic data object, in response to verifying the pre-end position as inefficient, the parking-space-search-traffic data object identifying the pre-end position as the start of the search for parking; and
outputting the parking-space-search-traffic data object for use in automatically identifying available parking for vehicles.

Abstract
Processing position data relating to a vehicle, in order to determine the start of a search for a parking space, includes determining an end position and determining at least one inefficiency value by comparing at least part of a drive with at least one linear distance to the end position, wherein the at least one inefficiency value identifies an inefficiency of the drive. The process further includes determining at least one route inefficiency value based on position data from a map to verify an identified inefficiency for at least one position for which an inefficiency has been identified. Parking space search traffic can then be output, as detected, if there is a route inefficiency.
