Title (EN) METHOD FOR EVALUATING THE DISTANCE BETWEEN AN IDENTIFIER AND A VEHICLE, ASSOCIATED ELECTRONIC UNIT AND IDENTIFIER
(FR) PROCEDE D'EVALUATION DE LA DISTANCE SEPARANT UN IDENTIFIANT ET UN VEHICULE, UNITE ELECTRONIQUE ET IDENTIFIANT ASSOCIES
Abstract:
(EN) The invention relates to a method for evaluating the distance (d) between an identifier (20) fitted with a first wireless communication module (24) and a vehicle (10) fitted with a second wireless communication module (14), including the following steps: establishing a wireless connection (L) between the first wireless communication module (24) and the second wireless communication module (14); estimating said distance (d) on the basis of a propagation time of the electromagnetic signals involved in the wireless connection established (L); when the identifier (20) comes within the range of a signal (S) transmitted by the vehicle (10), evaluating said distance (d) by means of a measurement, by the identifier (20), of the strength of said transmitted signal (S). An associated electronic unit and identifier are also described.
(FR) L'invention concerne un procédé d'évaluation de la distance (d) séparant un identifiant (20) équipé d'un premier module de communication sans fil (24) et un véhicule (10) équipé d'un second module de communication sans fil (14), comprenant les étapes suivantes : - établissement d'une liaison sans fil (L) entre le premier module de communication sans fil (24) et le second module de communication sans fil (14); - estimation de ladite distance (d) en fonction d'un temps de propagation de signaux électromagnétiques impliqués dans la liaison sans fil établie (L); - lorsque l'identifiant (20) entre dans la portée d'un signal (S) émis au niveau du véhicule (10), évaluation de ladite distance (d) au moyen d'une mesure, par l'identifiant (20), de la puissance dudit signal émis (S). Une unité électronique et un identifiant associé sont également décrits.
