Method and system for optimising a detected parking space

A method for the improved use of a parking space detected by a parking assistance system, comprising the following-steps:

• a) detecting, by a computer comprising a processor, a potentially usable parking space by initially capturing at least one partial area of the parking space by means of a sensor system of a vehicle;
• b) determining, by the computer, an initial parking area contour and an initial parking area orientation for the detected, potentially usable parking space and determining a quality criterion for the parking space;
• c) changing, by the computer, the parking area orientation by rotating the initial parking area contour or a parking area contour derived therefrom about a vertical axis, resulting in a parking area contour with a changed rotational position;
• d) calculating, by the computer, a modified quality criterion based on the changed rotational position of the parking area contour;
• e) checking, by the computer, whether the quality criterion for the parking space has improved;
• f) iteratively repeating, by the computer, acts c) to e) until an abort criterion has been reached;
• g) determining, by the computer, a final parking target area with a final parking area contour and parking area orientation based on the highest quality criterion determined;
• and
• h) carrying out, by the computer, a parking process in such a way that the vehicle is parked in the final parking target area.
