Abstract

La présente invention concerne un procédé de sortie à partir d'une phase de récupération dans un véhicule hybride parallèle, le véhicule se trouvant, dans une première étape, dans une phase de récupération, lancée au moyen d'un déclencheur, par la demande du conducteur de récupération prédéterminée et, dans une deuxième étape, le moteur électrique étant amené, au cours de la récupération, au régime moteur élevé. Dans une troisième étape, au moyen d'un déclencheur, une phase de sortie à partir de la phase de récupération commence, le moteur à combustion interne étant rendu disponible dans cette phase pour un couplage au moteur électrique de sorte qu'un régime moteur cible déterminé se règle entre le moteur à combustion interne à relier et le moteur électrique, pour le raccordement à la boîte de vitesse et, parallèlement, au moyen de la montée des vitesses, la vitesse la plus élevée possible est réglée, pour le raccordement à la chaîne cinématique, pour répondre à une demande du conducteur actuelle. Dans une quatrième étape, la sortie à partir de la phase de récupération est achevée.
