Abstract

Dans un procédé d'évaluation d'une distance (d) entre un premier module (10) équipant un véhicule et un second module équipant un identifiant, le premier module (10) comprend un émetteur acoustique (14) à base de microsystème électromécanique et le second module (20) comprend un récepteur acoustique (24). Ladite distance (d) est évaluée en fonction d'un instant de réception par le récepteur acoustique (24) d'un signal acoustique (A) émis par l'émetteur acoustique (14). Un module électronique est également décrit.
