ABSTRACT:
A method for determining at least the position of a moving part of the drive assembly, in which the part is illuminated or exposed to light and thereby the passage of light between the moving part and a part which corresponds thereto is determined. The passage of light changes or can even be briefly interrupted during the movement of the part. As a result, it is possible to obtain reliable information about the instantaneous position of the respective part. The method can be used more widely than the known capacitive determination of the position of a moving part and is, in particular, independent of the material of the part.
