Abstract

Dispositif d’émission/réception pour véhicule automobile La présente invention concerne un dispositif d’émission/réception (DE) pour véhicule automobile comprenant un émetteur-récepteur (TxRx1) configuré pour émettre un signal primaire (S1) et communiquer avec un identifiant (Id), selon lequel ledit dispositif d’émission/réception (DE) comprend en outre un dispositif d’intégration (DI) dudit émetteur-récepteur (TxRx1) : formé d’un volume d’intégration (Vo) comprenant une surface de placement (Sp) pour ledit identifiant (Id), et agencé dans ledit véhicule automobile de sorte qu’un signal primaire reçu (S1’) par ledit identifiant (Id) correspondant audit signal primaire (S1) émis subit une atténuation primaire (α1) inférieure ou égale à une valeur d’atténuation seuil (vs1) lorsque ledit identifiant (Id) est positionné sur ladite surface de placement (Sp) et lorsque ledit émetteur-récepteur (TxRx1) est disposé dans ledit volume d’intégration (Vo) à une distance (D) dudit identifiant (Id) inférieure ou égale à une distance maximale (Dmax). Figure pour l’abrégé : Figure 1The present invention relates to a transmission / reception device (DE) for a motor vehicle comprising a transceiver (TxRx1) configured to send a primary signal (S1) and communicate with an identifier (Id ), according to which said transmission / reception device (DE) further comprises an integration device (DI) of said transceiver (TxRx1): formed of an integration volume (Vo) comprising a placement surface ( Sp) for said identifier (Id), and arranged in said motor vehicle so that a primary signal (S1 ') received by said identifier (Id) corresponding to said primary signal (S1) transmitted undergoes a lower primary attenuation (α1) or equal to a threshold attenuation value (vs1) when said identifier (Id) is positioned on said placement surface (Sp) and when said transceiver (TxRx1) is disposed in said integration volume (Vo) at a distance (D) of said identifier (Id) less than or equal to a maximum distance (Dmax).
