Abstract

L’invention concerne un procédé (10) de détection acoustique, par un véhicule, d'un objet (2) ou d’un phénomène naturel susceptible de produire un son, caractérisé en ce qu’il comprend : Une étape de détermination (13) d’une durée d’émission globale correspondant à la somme des intervalles de temps successifs pour lesquels un pic fréquentiel est détecté ; Une étape de détection (14), parmi lesdites fréquences calculées pour chaque pic fréquentiel détecté, d’un motif sonore ; Une étape d’identification (15) d’un véhicule automobile en fonction de la durée d’émission et du motif sonore. Figure pour l’abrégé : figure 1The invention relates to a method (10) for the acoustic detection, by a vehicle, of an object (2) or of a natural phenomenon capable of producing a sound, characterized in that it comprises: A determining step (13 ) an overall emission duration corresponding to the sum of the successive time intervals for which a frequency peak is detected; A detection step (14), among said frequencies calculated for each frequency peak detected, of a sound pattern; An identification step (15) of a motor vehicle according to the duration of emission and the sound pattern.
