Title (EN) SYSTEM AND METHOD FOR HEATING VEHICLE TRANSMISSION FLUID WITH A CLUTCH
(FR) SYSTÈME ET PROCÉDÉ DE CHAUFFAGE DE LIQUIDE DE TRANSMISSION DE VÉHICULE AU MOYEN D'UN EMBRAYAGE
Abstract:
(EN) An automatic transmission system includes a housing containing automatic transmission fluid (ATF), a plurality of clutches configured to be engaged to generate gear ratios corresponding to forward speeds of the automatic transmission, wherein one clutch of the plurality of clutches is a friction clutch movable between a disengaged state, an engaged state utilized to create one or more gear ratios of the automatic transmission, and a slippingly engaged state between the disengaged state and the engaged state where the friction clutch is not engaged to create a gear ratio of the automatic transmission, and a controller configured to selectively move the friction clutch to the slippingly engaged state when the friction clutch is not being utilized to generate the one or more gear ratios, such that the friction clutch generates heat from friction to thereby rapidly heat the ATF in the housing and improve operating efficiency of the transmission.
(FR) Un système de transmission automatique comprend un carter contenant un fluide de transmission automatique (ATF), une pluralité d'embrayages conçus pour être embrayés de sorte à générer des rapports de vitesse correspondant à des vitesses de marche avant de la transmission automatique, un embrayage parmi la pluralité d'embrayages étant un embrayage à friction mobile entre un état débrayé, un état embrayé utilisé pour créer un ou plusieurs rapports de vitesse de la transmission automatique, et un état embrayé à glissement entre l'état débrayé et l'état embrayé où l'embrayage à friction n'est pas embrayé pour créer un rapport de vitesse de la transmission automatique, et un dispositif de commande conçu pour déplacer de manière sélective l'embrayage à friction à l'état embrayé à glissement lorsque l'embrayage à friction n'est pas utilisé pour générer le ou les rapports de vitesse, de sorte que l'embrayage à friction génère de la chaleur par frottement afin de chauffer rapidement l'ATF dans le carter et d'améliorer l'efficacité de fonctionnement de la transmission.
