An ECU executes a program based on which, when a fuel-supply cutoff control is executed or when a hybrid vehicle travels in a second mode in which the engine is stopped and the hybrid vehicle travels using only the drive power generated by a second MG an intake VVT mechanism is controlled so that a valve phase is brought to the mechanically determined most retarded phase. The phase, which is detected by a cam position sensor, is learned as the most retarded phase.

Une unité de réglage électronique (ECU) exécute un programme sur la base duquel lorsqu'une commande de coupure de l'alimentation en carburant est exécutée ou lorsqu'un véhicule hybride fonctionne dans un second mode dans lequel le moteur est coupé et le véhicule hybride fonctionne uniquement au moyen de la puissance motrice générée par un second moteur-générateur (MG), un mécanisme de distribution à programme variable (VVT) d'admission est commandé de sorte qu'une phase de soupape soit menée à la phase la plus retardée mécaniquement déterminée. La phase, qui est détectée par un capteur de position de came est acquise en tant que phase la plus retardée.
