Abstract
L’invention concerne un procédé d’ouverture d’un ouvrant de véhicule automobile (V), le véhicule (V) étant équipé d’un dispositif de détection (D) d’un mouvement prédéterminé d’une partie du corps d’un utilisateur, comprenant au moins un radar doppler, comprenant une antenne (A) des moyens d’émission et de réception d’ondes radar (10), et des moyens de traitement (20) des ondes radar réfléchies adaptés pour détecter le mouvement prédéterminé, le procédé comprenant des modes de détection (P1) ayant une fréquence d’émission et des modes de veille (P2) pendant lesquelles la fréquence d’émission des ondes est diminuée, le procédé étant caractérisé en ce qu’il comprend pendant les modes de veille (étape E0) les étapes suivantes : • Démodulation en phase (étape E2) des ondes radar réfléchies (étape E1) et détermination d’un premier signal (I) représentant une variation de phase des ondes réfléchies selon le temps (t), • Démodulation en décalage de phase (étape E3) des ondes radar réfléchies (étape E1), et détermination d’au moins un deuxième signal (Q) représentant une variation de phase des ondes réfléchies décalée selon le temps (t), • Comparaison (étape E4) entre un seuil prédéterminé (S) et une valeur maximum des valeurs absolues du premier signal (I’) et du deuxième signal (Q’), • Arrêt du mode de veille et déclenchement du mode détection (étape E5) si le maximum est supérieur au seuil prédéterminé (étape E6), • Ouverture de l’ouvrant (étape E7) si le mouvement prédéterminé est détecté pendant le mode de détection.
