Abstract: A method for determining a recognition threshold for recognizing the presence of a tooth or a tooth gap of a position sensor in front of a sensor is presented. The method includes a step of reading in a sensor signal which represents a variation over time of a measured magnetic field when the teeth and the tooth gaps of the position sensor are passed by the sensor. In addition, the method includes a step of ascertaining from the sensor signal a first value based on a minimum value of the sensor signal and a first value based on a maximum value of the sensor signal within a predefined time interval. The method also includes a step of computing a differential absolute value which represents a predetermined percentage of a difference between the value based on the at least one maximum value and a value based on the at least one minimum value of the sensor signal.
