The invention relates to a method for the contactless driving of a window pane (1) of a motor vehicle, which is actuated by an external force, towards an upper stop position (A), said position being provided with a seal (5). When an upper edge (2) of the pane reaches the stop position (A), a control signal is generated by a control unit (26), whereby the electric drive is disconnected in a disconnect position (11) pa and/or the drive direction thereof is reversed, in such a way that the upper edge (2) of the pane comes to a standstill in a zero position (10) p0. During the approach of the window pane (1) towards the stop position (A), system parameters (S1 Sn) are detected by sensors (27) and stored in a memory (28). A system state SZ (S1 - Sn), which is dependent on the system parameters (S1 - Sn), is read from an identification field, together with the disconnect position (11) pa. A difference DELTA SZ is calculated from a comparison between the respective current system states SZakt (S1 - Sn) and the comparison system state SZvergleich (S1 Sn) which has been stored in the memory (28). A new disconnect position (11.1)paneu is calculated based on the deviation DELTA SZ that has been determined. |
