Abstract

A path is determined in the following iterative way: An arcuate path around the reference position having a predetermined spacing is determined step-by-step. The existence of an obstacle along the arcuate path is checked. The arcuate path is lengthened as long as no obstacle is found. When an obstacle is found, the spacing is enlarged by a prescribable value and the method is continued in a new iteration with the enlarged spacing.
