A method (500) and calculating unit (110) in a vehicle (100), for determining the lane position of the vehicle (100) on a road (130). The method (500) comprises determination (501 ) of geographical position (140) of the vehicle (100). The method (500) further comprises detection (502), by means of a sensor (120), of a reference object (150, 160, 170) associated with the road (130) and a comparison (504) in a cartographic database (640) between stored lane-related data for the determined (501 ) geographical position (140) and the detected (502) reference object (150, 160, 170) at said geographical position (140). The method (500) further comprises determination (505) of the lane position of the vehicle (100) by matching the detected (502) reference object (150, 160, 170) associated with the road (130) to stored lane-related data for the determined (501 ) geographical position (140) of the vehicle (100). |
