Abstract
A method for preventing collisions when driving at least two movers on a drive surface, each mover comprising at least one magnetic field generator, with a device comprising a plurality of plate-shaped sectors, the sectors each comprising at least one electric magnetic field generator. The sectors form the drive surface, generating magnetic fields via control of a power supply of the electric magnetic field generators such that the movers are movable over the drive surface in at least one direction. A first path planning for the first mover is carried out, an estimated second travel path of the second mover is determined or received, and the estimated second travel path of the second mover is taken into account in the first path planning of the first mover to determine a first travel path for the first mover such that collision of the first mover with the second mover is prevented.
