Abstract

A system includes vehicles, a central control unit, and a stationary transceiver module connected to the central control unit via a bidirectional communications channel. Each has a transceiver module for bidirectional communication with the stationary transceiver module and/or a vehicle. The transceiver module has a controllable light source and a light sensor. The central control unit transmits driving orders to the vehicles via the stationary transceiver module. A first vehicle that is located within the spatial transmission area of the stationary transceiver module forwards a driving order to a second vehicle that is located outside the spatial transmission area of the stationary transceiver module, and the second vehicle transmits data via the first vehicle and the stationary transceiver module to the central control unit.
