Abstract

A device and method for preventing a collision when determining travel paths for at least two movers on a drive surface, each mover comprising at least a second magnetic field generator, the device comprising a plurality of sectors, the sectors comprising magnetic field generators for generating magnetic fields, the sectors forming the drive surface. A path planning for at least two movers is carried out, at least the two movers being assigned a priority, the priorities of the movers being taken into account in the path planning such that a path of a mover is assigned a priority in the path planning of the travel paths of the movers, and a travel path of a mover with a higher priority takes precedence over a travel path of a mover with a lower priority, so that a collision of the movers is prevented.
