Abstract

La présente invention a pour objet un dispositif de détection (D') d'un badge d'accès « main libre » autour d'un véhicule et de détection de la présence d'un utilisateur à proximité d'un ouvrant du véhicule, ledit dispositif de détection (D') comprenant des moyens de commande (10), générant un signal de commande (Sc), comprenant des trames radiofréquence (TLF) ayant une fréquence (F), à destination d'une antenne (40), ladite antenne (40) étant connectée à une première extrémité aux moyens de commande (10) et connectée à une deuxième extrémité à la masse, et émettant un signal radiofréquence de détection d'un badge d'accès « main libre » autour du véhicule, L'invention propose que le dispositif de détection (D') comprenne en outre : ? des moyens de mesure d'une variation de capacité aux bornes de l'antenne (40), représentative de la présence d'un utilisateur à proximité d'un ouvrant du véhicule. Ainsi l'antenne (40) a deux fonctionnalités, celle d'antenne (40) et d'électrode. L'invention concerne également un procédé de détection associé.The present invention relates to a device (D ') for detecting a “hands-free” access badge around a vehicle and for detecting the presence of a user near an opening of the vehicle, said detection device (D ') comprising control means (10), generating a control signal (Sc), comprising radiofrequency frames (TLF) having a frequency (F), intended for an antenna (40), said antenna (40) being connected at a first end to the control means (10) and connected at a second end to earth, and emitting a radiofrequency signal for detecting a “hands-free” access badge around the vehicle, L The invention proposes that the detection device (D ') further comprises:? means for measuring a variation in capacitance at the terminals of the antenna (40), representative of the presence of a user near an opening of the vehicle. Thus the antenna (40) has two functions, that of the antenna (40) and of the electrode. The invention also relates to an associated detection method.
