Abstract
In order to determine the actuation position of a motor-driven adjusting element of a motor vehicle, a Hall-effect sensor is located in a rotatable magnetic field, wherein a periodic change in the magnetic flux density sensed by the Hall-effect sensor is converted into a binary pulse train in that a pulse transition takes place when an upper switching threshold is positively exceeded and when a lower switching threshold separated from the upper switching threshold by a hysteresis is negatively exceeded. The hysteresis is reduced following an inactive phase of the Hall-effect sensor during which the magnetic field was stationary and/or the Hall-effect sensor was deactivated, if the magnetic flux density at the start of the inactive phase has exceeded the upper switching threshold by no more than a predefined tolerance range.
