Title
(EN) METHOD AND APPARATUS FOR POWER FLOW MANAGEMENT IN ELECTRO-MECHANICAL TRANSMISSION
(FR) PROCEDE ET APPAREIL DE GESTION DE FLUX DE PUISSANCE DANS UNE TRANSMISSION ELECTROMECANIQUE
Abstract
(EN) A method for power management in an electro-mechanical power-split infinitely variable transmission (102) designed to operate within a designated speed ratio range for vehicular applications. The transmission (102) is comprised of an input shaft (103) coupled to the output shaft of a drive engine (100) to receive power, a drive shaft (104), two electric machines, E1, E2 and a pair of planetary trains U1, U2, each having a sun member S, a ring member R, a set of planetary members P, and a planet carrier C. The transmission (102) further contains one or more torque transfer devices L to connect or disconnect members of the planetary trains U1, U2 for transferring torque. The drive shaft (104) is coupled with a final drive (106) of a vehicle for delivering or recapturing power to or from the vehicle drive wheels (105). The two electric machines E1, E2 are interconnected electronically via a power control unit (120) and are coupled respectively with members of the planetary trains U1, U2. The method of power management in the transmission (102) is selected based on the current speed and torque of the input shaft (103) and drive shaft (104), and upon the desired operating parameters.
(FR) La présente invention concerne un procédé de gestion de puissance dans une transmission (102) électromécanique variable à répartition de couple infinie conçue pour fonctionner dans une plage de rapport de vitesse déterminée d'applications de véhicule. Cette transmission (102) est constituée d'un arbre d'entrée (103) couplé à l'arbre de sortie d'un moteur d'entraînement (100) de façon à recevoir la puissance, un arbre de transmission (104), de deux machines électriques E1, E2 et une paire de trains planétaires U1, U2, chacun de ces trains possédant une roue solaire S, une bague R, un ensemble d'éléments planétaires P et un porte-satellite C. Cette transmission (102) contient aussi un ou plusieurs dispositifs de transfert de couple L permettant de connecter ou de déconnecter des éléments des trains planétaires U1, U2 afin de transférer le couple. L'arbre de transmission (104) est couplé à un entraînement final (106) de véhicule de façon à délivrer la puissance aux roues du véhicule (105) ou à recapturer cette puissance de ces dernières (105). Les deux machines électriques E1, E2 sont électroniquement interconnectés via une unité de commande de puissance (120) et sont couplées respectivement aux éléments des trains planétaires U1, U2. Le procédé de gestion de puissance de cette transmission (102) est sélectionné à partir de la vitesse et du couple courant de l'arbre d'entrée (103) et de l'arbre de transmission (104) et de paramètres de fonctionnement souhaités.
