The present disclosure relates to a method performed by a floor determining device (1) of a vehicle (2) for determining on which floor (f0, f1, f2, f3) of a parking area (3) comprising at least two floors, the vehicle is positioned. The floor determining unit determines, by means of a match determining unit (101) comprised in the floor determining device, that the vehicle at a current position (21, 24) has driven a travelled distance (23, 26) from a previous position (22, 25) of the vehicle, which previous position is a position which horizontally coincides with the current position and/or which previous position is a position from which the vehicle has turned 360 degrees. The floor determining device determines, by means of a floor change determining unit (104) comprised in the floor determining device, that the current position is situated on a higher floor (f1) above a previous floor (f0) 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. The disclosure also relates to a floor determining device in accordance with the foregoing, and a vehicle comprising such a floor determining device. |
