Abstract

The invention relates to a windshield wiper drive unit having a drive motor (1) and a gear (2, 3) for transmitting a rotary motion of the motor (1) to the shaft of a windshield wiper, having at least one sensor (6) for detecting a position of the shaft, and having a control circuit (4), which receives a detection signal of the sensor (6) and has one or more inputs (7) for receiving operating signals that define a desired operating state of the windshield wiper and is arranged to control a sequence of motions of the shaft as a function of the operating signal received, in which the control circuit (4) is combined with the drive motor (1) and the at least one sensor to make an integral component unit.
