Driver assistance system and method for performing an at least partially automatic vehicle function depending on a travel route to be assessed

A method for performing an at least partially automatic vehicle function of a vehicle depending on a new travel route to be assessed using a driver assistance system, the method comprising, by the driver assistance system:

• obtaining route data of at least one known travel route during at least a training process, wherein the route data has been recorded while traveling on the at least one known travel route;
• determining, a plurality of clusters from the route data of the at least one known travel route, wherein the clusters group the route data section-wise according to predefined geometric parameters, wherein regions of the at least one known travel route that have identical or similar geometric properties are associated to a single cluster of the plurality of clusters;
• providing recorded course data that indicate a course of the new travel route to be assessed, different from the known travel route, and applying the plurality of clusters, obtained from the at least one known travel route, to the course data of the new travel route to be assessed in order to divide the new travel route to be assessed into route sections, and, as a result, to at least assign a first cluster of the plurality of clusters to a first route section;
• determining at least one uncertainty quantity which is characteristic of an uncertainty with respect to the assignment made between the first route section and the first cluster assigned to said first route section, wherein the uncertainty quantity is characteristic of the uncertainty of the chosen cluster assignment and thus describes a degree of similarity of the first route section of the new travel route to be assessed to a region of the known travel route based on the geometric properties;
• determining at least one control quantity as a function of the uncertainty quantity;
• providing the at least one control quantity to the at least partially automatic vehicle function for performing the at least partially automatic vehicle function;
• wherein for each route section of the new travel route to be assessed, to which route section a cluster is assigned, a corresponding control quantity is determined depending on the respectively assigned cluster and is provided to the at least partially automatic vehicle function;
• and
• controlling the vehicle at least partially automatically using the at least partially automatic vehicle function.
