• determine at least two sub-lanes in the lane based on the determined width of the lane and the nearest boundary of the lane;
• and
• ascertain the position of the vehicle with respect to one of the at least two determined sub-lanes based on of the width of the lane and the distance of the vehicle to the nearest boundary of the lane.

A non-transitory computer-readable storage medium on which is stored a computer program including commands for ascertaining a position of a vehicle within a lane, the commands, when executed by a computer, causing the computer to perform the following steps:

• providing image data, wherein the image data result from a recording by at least one camera of the vehicle;
• analyzing the image data in order to determine a width of the lane and a distance of the vehicle to a nearest boundary of the lane;
• determining at least two sub-lanes in the lane based on the determined width of the lane and the nearest boundary of the lane;
• and
• ascertaining the position of the vehicle with respect to one of the at least two determined sub-lanes based on of the width of the lane and the distance of the vehicle to the nearest boundary of the lane.
