SYSTEM AND METHOD FOR PRECISION VEHICLE POSITIONING

A method and a system for precision vehicle positioning based on a digital road description database containing fourth data sets with object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. First data sets based on the fourth data sets are forwarded to a vehicle. The vehicle is collecting ambient data like images along its path, generating second data sets comprising at least location information and detailed object-based information. During driving and after generating second data sets, the vehicle tries to identify in the second data sets the same driving-relevant objects and/or object reference points and/or groups of driving-relevant objects and/or object reference points as are contained in the first data sets. Furthermore, the vehicle aligns the same driving-relevant objects and/or object reference points and/or groups of driving-relevant objects and/or object reference points between the second data sets and the first data sets, and derives a position value for its own position.
