ABSTRACT:
An access arrangement for a vehicle (FZ) has a transmit/receive device on the vehicle side (19) to transmit one or several interrogation signals. In addition, the access arrangement has a mobile identification generator (IDI, IDA) with a transmit/receive device on the identification generator side (SE) to receive interrogation signals from the transmit/receive device on the vehicle side and to evaluate signal characteristics of the interrogation signals at at least two different points in time. The mobile identification generator furthermore has a control device (ST) to output a different control command depending on a change (ΔFS, ΔFR) in the evaluated signal characteristics. In the event of no change or a small change in the signal characteristics, a signal may be output to deactivate the identification generator, while in the event of a marked change a locking signal to lock a door (TFZ) of the vehicle may be output.
