Beschreibung
Zusammenfassung:	A windshield wiper drive device for driving a windshield wiper (11) in an alternating motion in a range of motion (17) between two turning point positions (A, C) includes a motor (1) for moving the windshield wiper (11), a detector (6) for detecting a time at which the windshield wiper (11) moves past a given position (A, C) in the range of motion (17), a control circuit (8) for reversing the direction of motion of the motor (1) at each turning point position (B, D), and an incremental transducer for detecting the distance traveled by the windshield wiper (11) from the given position (A, C). The control circuit (8) reverses the direction of motion of the motor (1) as soon as it is detected that the windshield wiper (11) has traveled a defined distance.
