METHODS AND SYSTEMS FOR TERRAIN-BASED LOCALIZATION OF A VEHICLE

A method of terrain-based localization of a vehicle is provided. The method may include determining the vehicle is within a threshold distance of a road segment end point and comparing a measured road profile to a reference road profile associated with the road segment. A method of identifying a track (e.g., a lane) of a road segment road profile is provided. The method may include determining if a number of stored road profiles exceeds a threshold number of road profiles and identifying one or more clusters in the stored road profiles if the threshold number is exceeded.
