Abstract

La présente invention a pour objet un procédé de détection d'approche d'un objet (V2) sur un côté latéral d'un véhicule automobile (V1) en déplacement, ledit véhicule (V1) étant équipé de poignées de portières (10, 20) sur ledit côté latéral comportant chacune une antenne en ultra haute fréquence (BLE1, BLE2), adaptées, lorsque le véhicule (V1) est à l'arrêt, pour détecter la présence d'un équipement portable d'utilisateur à proximité du véhicule et pour identifier ledit équipement afin de valider l'accès main libre du véhicule (V1) à l'utilisateur, ledit procédé étant caractérisée en ce que ; • l'on adapte préalablement les antennes de telle manière que chacune des dites antennes émette un champ électromagnétique, dont une première puissance rayonnée (P1) par stéradian dans une première zone (Z1) orientée vers l'extérieur du véhicule définie par un premier angle d'ouverture (α) est plus grande qu'une deuxième puissance rayonnée (P2) par stéradian dans une deuxième zone (Z2) latérale dirigée vers l'autre antenne définie par un deuxième angle d'ouverture (β), • et, lorsque le véhicule est en déplacement, la détection d'approche de l'objet est validée par la réception par au moins une antenne d'un champ électromagnétique émis par l'autre antenne et réfléchi par l'objet, dont la puissance reçue est supérieure à une puissance reçue minimum prédéterminée.
