Abstract
To reduce the risk of collisions of transport units or of a transport unit with an obstacle in the movement plane in a planar motor, at least two movement paths in the movement plane are expanded two-dimensionally around the respective movement path, at least in sections, to form a movement route in the movement plane. A conflict zone, in which there is a risk of collision, is determined by checking, whether there is any overlap between the at least two movement routes, in either individual movement route or between a movement route and an obstacle. The determined conflict zone is taken into account when controlling the movement of the transport units along the assigned movement path in order to avoid collisions between transport units moving on movement routes involved in the conflict zone or between a transport unit and the obstacle in the movement path.
