Abstract

A method performed by a floor determining device of a vehicle is provided for determining on which floor of a parking area the vehicle is positioned. The floor determining unit determines by means of a match determining unit that the vehicle at a current position has driven a travelled distance from a previous position of the vehicle, which horizontally coincides with the current position. The floor determining device determines by means of a floor change determining unit that the current position is situated on a higher floor above a previous floor of the previous position if the vehicle is determined to have driven the travelled distance more upwards than downwards from the previous position to the current position, and that the current position is situated on a lower floor beneath the previous floor if the vehicle is determined to have driven the travelled distance more downwards than upwards.
