Abstract:
A method for measuring the pole position of a magnetic levitation vehicle on a magnetic levitation track. The pole orientation angle between the stator magnetic field of a track side stator and the magnetic reference axis of the magnetic levitation vehicle is determined by way of measured values from magnetic field sensors. The measured values for the stator magnetic field are measured using at least three magnetic field sensors, arranged along the vehicle longitudinal direction, a field strength value is determined for each measured value from the magnetic field sensors for each magnetic field sensor position and the pole orientation angle determined from at least a subset of the measured values from the magnetic field sensors when the determined field strength values meet given minimum requirements and, if not, an error signal is generated.
