Zusammenfassung:The present invention is about a system and method for evaluating the movement of an elevator car (1) within a hoistway. The same is based on gathering movement data of the car by means of a rotation encoder or acceleration sensor. Since these data are counted pulses there is a need to convert them into real movement data. This conversion is calibrated automatically by comparing the movement data with a length distance being passed by the car, wherein said length distance is configured to be unchangeable over the time. Base on the exact movement results gained therewith by means of said calibration one also gets better position results of the car in the hoistway.
