Abstract

L'invention concerne un procédé permettant l'interrogation sans fil de la présence d'un appareil d'accès pour l'accès à un système de fermeture d'un véhicule automobile qui comprend sur son revêtement extérieur au moins une antenne NFC. L'antenne NFC est activée et désactivée en alternance pour générer un champ électromagnétique de sorte que des périodes de temps avec génération de champs alternent avec des périodes de temps sans génération de champs. Au moins un paramètre de fonctionnement de l'antenne NFC est surveillé durant la génération du champ électromagnétique et est comparé à au moins une valeur de comparaison enregistrée. Dans le cas où le paramètre de fonctionnement est différent de la valeur de comparaison, une interrogation de dialogue NFC est émise. Indépendamment de la comparaison, une émission répétée d'interrogations de dialogue NFC est effectuée selon une norme NFC pour le déclenchement d'un dialogue NFC avec un appareil d'accès NFC dans l'environnement, l'émission répétée d'interrogations de dialogue NFC étant effectuée dans des seconds intervalles de temps qui sont plus longs que les premiers intervalles.
