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