Abstract
A parking arrangement with parking places for vehicles and with an automatic vehicle detection system which comprises a central computer system and a wirelessly operating parking sensor module for determining the presence or absence of a vehicle in the parking place, which parking sensor module comprises at least one vehicle sensor, which provides measuring values which are representative of the presence or absence of a vehicle, provided with calibration means for determining the quiescent value, representing the absence of a vehicle, of the measuring values from the vehicle sensor, which calibration means by a self-organizing map method divide the measuring values into clusters of mutually close values, wherein the cluster having the largest number of measuring values is selected as representative of the quiescent value of the measuring values at a parking place, wherein each time an adjusted quiescent value is determined, and wherein a measuring value which differs from the quiescent value by more than a predetermined threshold value indicates that a vehicle is situated in the parking place.
