DEVICE AND METHOD FOR A WIPING SYSTEM

摘要

The invention pertains to a wiping device (10) for use mainly in vehicles, which prescribes, due to the determination of a correction value (K), an adjusted reference value (F), so that the deviation by the control circuit is virtually null. To set the position of at least one wiper (16) swinging between the two extreme positions (18.1; 18.2; 18.3) the system (10) includes an electronically reversible driving motor and a control unit (12) which compares a control value (R) with a reference value and sets the motor (14) based on a controlling variable (S). The deviation between the reference value (F) and the control value (R) and/or other parameters such as the controlling variable (S) or the quantity derived from the control value (R) is used to calculate an offset value (K) and, consequently, to adjust the reference value (F).
