Abstract: A device for controlling a driving function for the automated longitudinal guidance and/or lateral guidance of a vehicle is configured to determine driving situation data for different driving situations during the operation of the driving function in at least one vehicle, in which driving situations the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function was limited. The device is also configured to identify, based on the driving situation data for the different driving situations, a first type of driving situations for which and/or a first location at which the automated longitudinal guidance and/or lateral guidance of the vehicle effected by the driving function was frequently limited. Furthermore, the device is configured to cause the driving function not to be operated or to be operated only with a reduced degree of automation in a driving situation of the first type and/or at the first location.

Abstract: A device for determining a reference travel path for a road section determines a plurality of measured travel paths of one or more vehicles for a corresponding plurality of passages through the road section, and subdivides a course of the road section into a sequence of support point levels. For each of the plurality of measured travel paths, the device determines a sequence of cut points of the respective measured travel path with the corresponding sequence of support point levels and, for each sequence of support point levels, determines a respective amount of support points based on the determined cut points with the respective support point levels. The device determines at least one reference travel path for the road section based on the sequence of sets of support points for the corresponding sequence of support point levels.
