1. A system for creating a digital map for driver assistance systems of a vehicle, the system comprising:
a communications unit configured to exchange messages between vehicles;
a position acquisition unit configured to acquire the position of the vehicle;
a map unit configured to store and process a digital map; and
a detection unit configured to detect collision-warning-system ambiguities of a driving situation in relation to a position in the digital map, wherein the collision-warning-system ambiguities of the driving situation are caused erroneously based on a first road extending as an overpass above a second road at one or more positions at which the first road and the second road intersect, overlap, and/or extend in parallel with each other;
the detection unit further configured to output a message comprising map data and/or a warning message in response to detection of a collision-warning-system ambiguity by the detection unit.
