Abstract

La présente invention a pour objet un procédé (100) de détection d'un dispositif portable (20) pour accès « mains libres » à un véhicule automobile (30) embarquant un dispositif de détection (10). Pour détecter si le dispositif portable se trouve dans une zone de détection (Z1, Z2, Z3) prédéterminée, le procédé comporte : • une détermination (111) d'un niveau de bruit à générer prédéfini en fonction d'un niveau de puissance d'émission d'un message d'interrogation par le dispositif de détection à destination du dispositif portable, • une génération (112) de bruit au niveau déterminé pendant l'émission du message d'interrogation, • une vérification (113) si un message de réponse émis par le dispositif portable est reçu par le dispositif de détection. Le dispositif portable est détecté dans la zone de détection si un message de réponse est reçu en réponse au message d'interrogation.The present invention relates to a method (100) for detecting a portable device (20) for “hands-free” access to a motor vehicle (30) carrying a detection device (10). To detect whether the portable device is located in a predetermined detection zone (Z1, Z2, Z3), the method comprises: determining (111) a predefined noise level to be generated as a function of a power level d 'transmission of an interrogation message by the detection device to the portable device, • generation (112) of noise at the level determined during transmission of the interrogation message, • verification (113) whether a message response transmitted by the portable device is received by the detection device. The portable device is detected in the detection area if a response message is received in response to the interrogation message.
