Claim 15:
16. A system for generating an environmental model for a vehicle comprising:
a position acquisition receiver for acquiring an initial position estimate for the vehicle;
a map data acquisition receiver for acquiring map data based on the acquired initial position estimate, wherein the map data include information on the spatial arrangement of multiple geographical areas and the assignment of the geographical areas to one or more area categories;
an environmental data acquisition sensor for acquiring environmental data in an acquisition space;
a processor with a detection circuit and an environmental model determining circuit; and
a driver assistance system for at least partially autonomous control of the vehicle using the environmental model; wherein
the detection circuit is configured for detecting objects using the environmental data and for assigning an object position and an object category to each detected object; and
the environmental model determining circuit is configured for generating the environmental model using the detected objects and based on assignment rules, which assignment rules define one or more plausibility relationships between one or more object categories and one or more area categories; wherein generating the environmental model comprises:
determining, using the one or more assignment rules, whether for at least one given object of the detected objects, a positive assignment or a negative assignment exists between the assigned object category of the given object and an area category at the assigned object position of the given object; and
including the given objects in the environmental model in case the positive assignment exists for the given object; otherwise
not including the given object in the environmental model.
