Patent ID: 7841564

Claim:
A device for automatically controlling a track-bound magnetic levitation vehicle, comprising a drive and brake system for the vehicle, said system including a long-stator linear motor with at least one long-stator arranged along a guideway and at least one electric magnet mounted at the vehicle which is switched-on during a travel and thus keeps the vehicle in a suspended status while furnishing at the same time an excitation field for the long-stator linear motor; stopping zones arranged along the guideway; an additional brake at the vehicle; a travel computer for the drive and brake system, with said travel computer being stationarily arranged outside the vehicle; data carriers arranged along the guideway for a supply of status signals concerning a location, speed and/or travel direction of the vehicle; and means provided in the vehicle for switching-off the drive and brake system and for switching-on the additional brake, if a scanning of the data carriers reveal an impermissible travel status for the vehicle, said means being arranged for safely stopping and/or starting the vehicle at or from preselected target stopping points within the stopping zones and being so configured that an immediate decoupling of the vehicle from the drive and brake system is effected by switching-off the electric magnet when an impermissible travel status within an area of the stopping zone is reached, wherein the decoupling of the vehicle from the drive and brake system as well as the switching-on of the additional brake are effected when the vehicle starts into a wrong travel direction during a start within the stopping zone.
