| Zusammenfassung: | Transponder device for communication with a mobile antenna mounted on a motor vehicle. Said transponder device comprises n antennae (A1, An), where n is greater than 1, to ensure coupling with the mobile antenna and p transponders (12), where p is less than n, with each transponder connected to the assembly of n antennae and having a commandable assembly for decoding a signal received by the antennae or encoding a signal to transmit; with the said antennae arranged in the road surface or below it. The invention also relates to a corresponding communication system comprising a fixed transponder system mounted in the road surface or beneath it and a moving antenna carried by a motor vehicle. Said system can be used to control the trajectory of a motor vehicle.
L'invention concerne un dispositif à transpondeur destiné à dialoguer avec une antenne mobile montée sur un véhicule. Le dispositif à transpondeur comprend : n antennes (A1, An), n > 1 pour réaliser un couplage avec ladite antenne mobile ; et p transpondeurs (12), p < n, chaque transpondeur étant relié à l'ensemble des n antennes, et comprenant un ensemble commandable pour coder le signal reçu par lesdites antennes et des moyens pour commander l'ensemble de codage à partir d'une information à transmettre ; lesdites antennes et le ou lesdits transpondeurs étant disposés sur la chaussée (10) ou sous la chaussée. |
