Claim 0:
1. A method for detecting the rotary angle positions of rotating parts of a wiper motor, the wiper motor having a brushless electric motor as a first part which comprises a rotor rotating about a first axis of rotation and which drives a gear wheel as a second part which rotates about a second axis of rotation and which comprises a driven shaft, and the rotary angle positions of the two rotating parts being detected by means of two sensor devices each having a signal generating element and a sensor element for detecting a changing physical parameter of the signal generating element,
characterized in that
an absolute angle position of both rotating parts is detected by means of a respective one of the sensor devices.
