Abstract:
1. A method for determining a reference position of a locking part moved by an electric motor, with the following steps: (a) moving the locking part in a direction of its closed state while simultaneously changing a counter state of a position counter until a first stop position of the locking part is reached, (b) detecting and buffering the counter state of the position counter describing the first stop position, (c) moving the locking part in a direction of its opened state, (d) moving the locking part in the direction of its closed state again until a second stop position is reached, (e) detecting a counter state of the position counter describing the second stop position, (f) checking whether the counter states describing the two stop positions match, and (g) fixing the first stop position as the reference position if a match between the counter states is recognized.
