Abstract

When a sub-section of a predefined path temporarily cannot be traversed by an autonomous mobile unit, an extended path is found for subsequently traversing the temporarily blocked sub-section. A first path point of the predefined path is determined using at least one predefinable distance criterion, which takes into consideration the distance of the temporarily blocked sub-section from the first path point. An extension sub-section is determined which begins at the first path point, terminates at a second path point of the predefined path and encompasses at least the temporarily blocked sub-section. The extended path is programmed with the extension sub-section being integrated into the predefined path at the first path point.
