Abstract: The actual floor level of each of the floors of a building is determined and stored as a data point in memory by detecting, for each floor, the position of a point located a predetermined distance above the floor level and the position of a point located a predetermined distance below the floor level, storing data representing the above and below points in memory, and calculating a data point for the actual floor level located at the midpoint between the points above and below the actual floor level in the case where the points are the same predetermined distance above and below the actual floor level. The data stored in memory as to the positions of the points is continuously updated each time the elevator cage passes by each floor, and the data point of the actual floor level is recalculated to provide an updated and accurate representation of the actual floor level in memory to account for cable stretch and other mechanical or electronic variations.
