Abstract

L'invention porte sur un véhicule hybride évitant à un conducteur de considérer sa batterie comme défectueuse alors que la batterie auxiliaire ne nécessite pas de recharge. Lorsque la charge de la batterie est inférieure à une valeur donnée, les conditions de fonctionnement de la commande de ralenti/arrêt changent sans qu'apparaisse un signal lumineux tel qu'un voyant, ce qui réduit la fréquence de la commande de ralenti/arrêt.
