A method and position determining arrangement determine a current precise position of an elevator car driven by a drive engine along a hoistway. An encoder cooperating with the drive engine provides a first signal indicating with a high precision the position of the car within a partial hoistway range extending along a fraction of the entire car travel path. A rough position indicator provides a second signal indicating with a low precision the position of the car within the hoistway. A current rough position of the car is determined based on the second signal and deviating from an exact real position of the car up to an first inaccuracy length; and the current precise position of the car is based on the first signal taking into account the current rough position and deviating from the exact real position up to a second inaccuracy length smaller than the first inaccuracy length.
