A transportation vehicle having: a keyless access system for the electronically controlled locking and unlocking of at least one vehicle door of the transportation vehicle and a UWB system having at least one UWB transceiver to transmit and receive UWB pulses via at least one antenna. In the transportation vehicle, the UWB system is used for a positioning method based on transit time measurements for determining the position of a second UWB system for controlling the keyless access system and for controlling the control unit for payload transmission with a third transceiver.

Transportation vehicle with ultrawideband communication

The application relates to an electrodynamic converter (), comprising a coil (), a claw disk () associated with the coil () and having a disk component () that can be rotated about an axis of rotation and a disk component () that is stationary relative thereto, comprising a further claw disk () associated with the coil () and having a disk component () that can be rotated about the axis of rotation and a disk component () that is stationary relative thereto, and comprising magnetic flux components, which have oppositely magnetized magnetic components () and magnetic flux elements composed of soft magnetic material, of which at least some are associated with a magnetic flux through the claw disk () or a further magnetic flux through the further claw disk () during operation, which are formed in alternation as the rotatable disk component () of the claw disk () and the rotatable disk component () of the further claw disk () are rotated, wherein the magnet-flux-closing relative positions for the claw disk () and the further claw disk () are formed having an angular offset to each other, as are also non-magnetic relative positions.
