Abstract: Systems and methods of evaluating parking spaces are provided, and in particular evaluating parking spaces in parking lots or parking garages, with regard to autonomous driving. This is accomplished by determining an accessible area of the parking space, and defining grid points in the accessible area. Features of the parking space are determined for each of the grid points, where each of the features is registrable from a respective one of the grid points. A quality value is obtained from an average number of features that is registrable from each of the grid points.

Abstract: According to a method for self-localization of a vehicle, a first pose of the vehicle is determined in a map coordinates system, based on environment sensor data representing an environment of the vehicle, a landmark is detected in the environment, a position of the landmark is determined in the map coordinates system and a second pose of the vehicle is determined in the map coordinates system dependent on the position of the landmark. An assignment instruction is consulted, matching up the first pose with at last one preferred sensor type or at least one dominant landmark type. Depending on the assignment instruction, a first environment sensor system is activated and a second environment sensor system is deactivated, whereupon the environment sensor data are generated by means of the first environment sensor system.
