Abstract: A method for assessing a control loop. In the method, the control loop is assigned one degree of fulfillment each with respect to at least three quality criteria. The surface area of a polygon having a geometry defined by the degrees of fulfillment is determined. An overall control quality of the control loop is evaluated on the basis of the surface area.

Abstract: 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.

Abstract: For steering a vehicle around obstacles, proceeding along a path from a starting position to an end position, the path including linear sub-paths which are defined by an increment ? and a steering angle ?, a method includes: a) determining a maximum steering angle range and a maximum and a minimum increment range; b) determining the present distance eP from the end position, the target angle ?O, and the angle difference e? between the present vehicle angle and the target angle; c) performing an optimization method for ascertaining a sub-path by minimizing the value of a cost function lo assigned to the sub-path; d) determining the new position by adding the ascertained sub-path to the present position; and e) repeating steps (b) through (d) until the end position is reached.
