Abstract

La vitesse de sortie du moteur (1) est commandée en vue d'une efficacité optimale par réglage de la vitesse d'entrée d'une transmission à réglage continu (3). Lorsqu'une quantité de puissance supérieure à celle fournie par le moteur (1) est requise, de la puissance supplémentaire est introduite dans le train d'entraînement par un moteur à fluide (7) mû par la pression d'un fluide accumulé dans un accumulateur (6). Dans des conditions de marche où le moteur (1), fonctionnant à un rendement optimum, produit une quantité de puissance dépassant celle demandée par le véhicule, le moteur à fluide (7) est inversé pour fonctionner comme pompe et cette puissance excédentaire est utilisée pour entraîner la pompe (7) et stocker l'énergie dans l'accumulateur (6) sous la forme d'une pression de fluide. Une unité centrale (18) de traitement des informations détermine la sortie de puissance requise du moteur (1) sous la forme d'une somme constituée par la puissance indiquée par un capteur (14), lequel détecte la puissance demandée du véhicule par le conducteur, et par une augmentation de puissance requise pour maintenir la pression de l'accumulateur (6) au-dessus d'une quantité seuil.
