Abstract
In a method of determining a current position of an output element connected to an electric stepper motor, a current position of a rotor of the stepper motor is determined by a rotor position sensor. The determination of the current position of the rotor is refined as a function of information about a currently active phase of the stepper motor, and the current position of the output element is calculated in response to the refined determination of the current position of the rotor.
