PCT No. PCT/DE97/02920 Sec. 371 Date Jul. 2, 1999 Sec. 102(e) Date Jul. 2, 1999 PCT Filed Dec. 16, 1997 PCT Pub. No. WO98/30422 PCT Pub. Date Jul. 16, 1998A regulated windshield wiper device (10), in particular for motor vehicles, is proposed, which predetermines a corrected guidance variable (F) by determining a correction variable (K) so that the regulating deviation of the control circuit becomes approximately zero. In order to regulate the position (X) of at least one wiper (16) that oscillates between two end positions (18.1, 18.2, 18.3), the windshield wiper device (10) includes an electronically reversible drive motor (14) and a regulating unit (12), which compares a regulation variable (R) to a guidance variable (F) and regulates the motor (14) by means of a control variable (S), wherein the deviation between the guidance variable (F) and the regulation variable (R) and/or other parameters, e.g. the control variable (S) or variables derived from the regulation variable (R), is used to calculate a correction variable (K) with which the guidance variable (F) can be corrected.
