Creation and updating of maps in the off-street area

An external server unit configured to create a map of at least one parking infrastructure by a server unit, unoccupied parking spaces inside the parking infrastructure being registered, the external server unit being configured to:

• receive items of path information and items of environmental information ascertained by a vehicle sensor system of at least one vehicle about a path of the at least one vehicle;
• subdivide the path information into path segments;
• rectify the path segments to compensate errors, and use the rectified path segments to create or update a geometrical map of the parking infrastructure;
• and
• based on the items of environmental information and based on the rectified path segments, acquire occupied and unoccupied parking spaces along the path of the at least one vehicle to ascertain unoccupied parking spaces inside the parking infrastructure,
• wherein the rectified path segments are combined to form loops, wherein each loop of the loops form a vertical level of the parking infrastructure, wherein changes of a parking space level are determined based on the ascertained occupied and unoccupied parking spaces along the path of the at least one vehicle, and being taken into account in the creation or updating of the map, and wherein changes of a level in the environmental information are determined.

A system, comprising:

• at least one vehicle each having a vehicle sensor system including at least one environmental sensor, at least one odometer, and a control device for receiving and evaluating sensor data of the vehicle sensor system;
• and
• at least one external server unit configured to create a map of at least one parking infrastructure by a server unit, unoccupied parking spaces inside the parking infrastructure being registered, the external server unit being configured to:
• receive items of path information and items of environmental information ascertained by the vehicle sensor system of the at least one vehicle about a path of the at least one vehicle,
• subdivide the path information into path segments,
• rectify the path segments to compensate errors, and use the rectified path segments to create or update a geometrical map of the parking infrastructure, and
• based on the items of environmental information and based on the rectified path segments, acquire occupied and unoccupied parking spaces along the path of the at least one vehicle to ascertain unoccupied parking spaces inside the parking infrastructure,
• wherein the rectified path segments are combined to form loops, wherein each loop of the loops form a vertical level of the parking infrastructure, wherein changes of a parking space level are determined based on the ascertained occupied and unoccupied parking spaces along the path of the at least one vehicle, and being taken into account in the creation or updating of the map, and wherein changes of a level in the environmental information are determined.
