Abstract

Un procédé de détermination de la distance entre un dispositif d’authentification porté par un utilisateur, et un véhicule (100) automobile, comprenant chacun un module de communication (50) sans fil afin d’échanger une trame de données, ladite trame de données étant modulée par changement de phase d’un signal de référence (S). Le procédé comprend les étapes de réception par le véhicule d’un signal (S) de référence modulé, envoyé par le dispositif, de démodulation du signal (S) reçu afin d’en extraire une composante en phase (I) et une composante en quadrature (Q), de calcul de la valeur de la puissance du signal (S) à partir de la valeur d’amplitude maximale de la composante en phase (I) et de la valeur d’amplitude maximale de la composante en quadrature (Q), et de détermination de la distance entre le dispositif et le véhicule à partir de la valeur de puissance calculée.
