A method for creating a map of at least one parking infrastructure. Unoccupied parking spaces inside the parking infrastructure are registered. Items of path information and items of environmental information are received by an external server unit. Items of path information are subdivided into path segments. The path segments are rectified by the external server unit. A loop recognition is carried out in order to create a geometrical map of the parking infrastructure. On the basis of the items of environmental information, occupied and unoccupied parking spaces along the path are acquired in order to ascertain unoccupied parking spaces inside the parking infrastructure. An external server unit and a system are also described.

Creation and updating of maps in the off-street area

A method for evaluating an height of an object in the surrounding environment of a vehicle, using ultrasonic signals acquired by an ultrasonic sensor mounted on the vehicle. In a measurement cycle, a first ultrasonic signal is acquired as an edge reflection or as a directly traveling echo of an object. An expectation window is calculated for an associated interior-corner reflection. A second ultrasonic signal acquired in the expectation window is recognized as an interior-corner reflection associated with the first ultrasonic signal. The first and second ultrasonic signals are combined to form a signal group. A significance is determined for each ultrasonic signal. The signal group is assigned to a first or second echo group. The rates of the assignment to the first and to the second echo group are determined over a number of measurement cycles. An evaluation of the height is based on the first and second rates.
