Abstract
A wireless control system comprises a plurality of local stations linked by a communication network. Each local station transmits, in a respective radio coverage area, an enduring status signal. An autonomous vehicle is authorized to move while it receives the status signal. When an emergency stop switch of the local station is activated, the local station interrupts its transmission of the status signal. It also instructs one or more further local stations, to which it is linked by a communication network, to interrupt their transmission of the status signal. In this way, the activation of the local emergency stop switch will have effect throughout the control system and will eventually bring all autonomous vehicles to a halt.
