Abstract

Von dem beim Überfahren einer Induktionsschleife durch ein Fahrzeug auftretenden Induktivitätsverlauf wird die größte sich beim Einfahren des Fahrzeugs in den Schleifen­ bereich ergebende Induktivitätsänderungsgeschwindigkeit und das erste auftretende Induktivitäts-Minimum festgestellt und zur Berechnung der Fahrzeuggeschwindigkeit ausge­ wertet, wobei der Betrag der maximalen Induktivitätsände­ rung und die Welligkeit des Induktivitätsverlaufs zur Klassie­ rung des Fahrzeugs herangezogen werden. Of that when crossing an induction loop due to a vehicle's inductance curve largest when entering the vehicle in the loops area resulting rate of inductance change and the first inductance minimum that occurs is determined and to calculate the vehicle speed evaluates, the amount of the maximum inductance changes and the ripple of the inductance curve for classification tion of the vehicle.
