Title
(EN) SYSTEM AND METHOD FOR ADAPTIVE CONTROL OF A HYDRAULIC CONTROL SYSTEM OF A TRANSMISSION
(FR) SYSTÈME ET PROCÉDÉ POUR LA COMMANDE ADAPTATIVE D'UN SYSTÈME DE COMMANDE HYDRAULIQUE D'UNE TRANSMISSION
Abstract
(EN)
The present disclosure provides a hydraulic system of a transmission having a controller and a variable displacement pump. The pump includes an inlet and outlet and is adapted to be driven by a torque-generating mechanism. The system also includes a lube circuit fluidly coupled to the pump. A lube regulator valve is disposed in the lube circuit, such that the lube regulator valve is configured to move between at least a regulated position and an unregulated position. The regulated position corresponds to a regulated pressure in the lube circuit. A pressure switch is fluidly coupled to the lube regulator valve and configured to move between a first position and a second position, where the switch is disposed in electrical communication with the controller. A solenoid is disposed in electrical communication with the controller and is controllably coupled to the pump to alter the displacement of the pump.

La présente invention concerne un système hydraulique d'une transmission ayant une unité de commande et une pompe volumétrique. La pompe comprend une entrée et une sortie et est conçue pour être entraînée par un mécanisme générateur de couple. Le système selon l'invention comprend en outre un circuit de lubrification fonctionnellement relié à la pompe. Une soupape de régulation de lubrification est disposée dans le circuit de lubrification, de telle sorte que la soupape de régulation de lubrification soit configurée pour se déplacer entre au moins une position régulée et une position non régulée. La position régulée correspond à une pression régulée dans le circuit de lubrification. Un commutateur de pression est raccordé fluidiquement à la soupape de régulation de lubrification et est configuré pour se déplacer entre une première position et une deuxième position, le commutateur étant disposé en communication électrique avec l'unité de commande. Une électrovanne est disposée en communication électrique avec l'unité de commande et est raccordée de manière commandable à la pompe pour modifier le volume de refoulement de la pompe.
