Title
(EN) CONTROL DEVICE
(FR) DISPOSITIF DE COMMANDE
Abstract
(EN) A control device including: an oil pump (24) configured to be driven by an engine (12); an oil amount adjusting apparatus (26) configured to adjust an oil level in an oil storage container (22) of a vehicle automatic transmission (16); the oil amount adjusting apparatus including: a discharge tube (28) provided upright on a bottom wall (22a) of the oil storage container in a liquid-tight manner; the discharge tube being configured to discharge oil that exceeds a discharge height (H) that is defined by a height of the discharge tube; a controller (40) configured to control the engine so as to obtain an oil surface height that is appropriate for adjustment of the oil level by the oil amount adjusting apparatus, the controller being configured to control a revolution number of the engine so as to maintain the oil surface height of the oil in a predetermined appropriate range regardless of a temperature of the oil.
(FR) La présente invention concerne un dispositif de commande comprenant : une pompe d'huile (24) configurée pour être entraînée par un moteur (12) ; un appareil de réglage de quantité d'huile (26) configuré pour régler un niveau d'huile dans un conteneur de stockage d'huile (22) d'une transmission automatique de véhicule (16) ; l'appareil de réglage de quantité d'huile comprenant : un tube de décharge (28) placé verticalement sur une paroi inférieure (22a) du conteneur de stockage d'huile de façon étanche aux liquides ; le tube de décharge étant configuré pour décharger l'huile dépassant une hauteur de décharge (H) définie par une hauteur du tube de décharge ; un système de commande (40) configuré pour commander le moteur de façon à obtenir une hauteur de surface d'huile appropriée pour régler le niveau d'huile au moyen de l'appareil de réglage de quantité d'huile, le système de commande étant configuré pour commander une vitesse de rotation du moteur de façon à maintenir la hauteur de surface d'huile de l'huile dans une plage appropriée prédéterminée indépendamment de la température de ladite huile.
