Abstract

L’invention propose un procédé d’activation d’une fonction véhicule, par un dispositif d’activation (D) comprenant un émetteur récepteur (E1) communiquant en ultra haute fréquence (BLE) avec un équipement d’accès « mains libres » (P), le procédé étant caractérisé en ce que l’on équipe au préalable l’émetteur récepteur (E1) d’un gyroscope (G1) et d’un magnétomètre (M1) et de deux antennes réceptrices (A1, A2) présentant un coefficient de couplage électromagnétique entre elles inférieur à un seuil, et en ce que ledit procédé comprend pour au moins deux pas consécutifs, les étapes suivantes : Emission d’un signal comprenant des données du gyroscope et du magnétomètre de l’équipement « mains libres » vers le véhicule,comparaison entre les dites données avec des valeurs représentatives du gyroscope et du magnétomètre de l’émetteur récepteur,détermination d’une première d’une direction (DIR1) de l’utilisateur,détermination d’une deuxième direction (DIR2) de l’utilisateur à partir d’une estimation d’un premier angle d’arrivée (φ0,φ1) dudit signal vers l’émetteur récepteur par calcul d’un déphasage (Δθ) entre les deux antennes, et d’une distance (RF0, RF1) entre l’équipement d’accès et l’émetteur,Comparaison entre la première direction et la deuxième direction,Activation de la fonction véhicule en fonction du résultat de ladite comparaison.
