Field: Transport (Mechanical engineering)
Classification: CPC B  G | IPC B  G

Claim 0:
1. An authentication element configured to transmit access authorization information from the authentication element to an access control device of a transportation vehicle, wherein the authentication element comprises:
a neural network for learning a plurality of operating movements for the operation of a door or tailgate of a transportation vehicle; and
communication equipment configured to determine whether an operating person is located in an immediate vicinity of the door or tailgate to be operated,
wherein the neural network determines whether the operating person performs a learned operating movement in the immediate vicinity for the door or tailgate operation, wherein, for checking whether the operating person performs a learned operating movement in the immediate vicinity for the door or tailgate operation, a preselection of a number less than a total of learned operating movements is made in which the authentication element selects the preselection of learned operating movements which are valid for an associated communication module on the transportation vehicle whose communication with the authentication element consecutively results in the shortest propagation time measurement to compare against movement of the operating person, wherein the communication equipment transmits information relating to the tailgate operating procedure to the access control device in response to the performance of the operating movement being verified, and
wherein the authentication element transmits consecutive ultra-wideband signals (UWB) signals during the approach to the transportation vehicle and the signals are answered by at least one communication module included in the access control device.
