Abstract
In order to increase safety, a computer-implemented method is proposed for determining the position of a lift cabin in a lift shaft with the aid of a coding device, which comprises a code band as a marking, wherein the position is determined analytically by means of an algorithm on the basis of the code of the marking, wherein an extrapolated position is determined from the stored positions and the instant of the recording and, in turn, a coding pattern to be compared in relation to the recording is calculated by inverting the algorithm.
