Abstract

The invention relates to a method for operating a closing device, wherein a closing element (2), with the aid of a drive motor (4) controlled by a control unit (7), can be displaced in a closing direction up against a stop edge, wherein the control unit (7) can be shifted into a normal-operation mode, in which position-related information is sensed as the current position of the closing element (2), and into a sleeping mode, in which no sensing of position-related information takes place, the method having the following steps: —interrogating whether a wake-up condition, in which the control unit (7) goes from the sleep mode into the normal-operation mode, is present; —if the presence of the wake-up condition is established, and if the closing element (2), prior to assuming the sleep mode, last moved in the closing direction, the position-related information is subjected (S25) to a predetermined correction value in order to correct the position-related information, in respect of an actual position of the closing element (2), into an opening direction.
