Title
(EN) METHOD FOR MANAGING THE USE OF POWER TO SUPPLY A HYBRID DRIVE TRAIN
(FR) PROCEDE DE GESTION D'UTILISATION D'ENERGIE POUR ALIMENTER UN GROUPE MOTOPROPULSEUR HYBRIDE
Abstract
(EN) The present invention relates to a method for supplying a hybrid drive train of a rechargeable hybrid vehicle from an internal irreversible power source and an internal reversible power source that can be recharged by drawing directly or indirectly from the internal irreversible power source and by providing a finite amount of reversible power from an external source. According to the invention, when the vehicle is in motion, a first step involves estimating the consumption rate of the amount of reversible power from the external source consumed (NRJ_consumed/Dist_from_recharge); estimating the consumption rate of the remaining amount of reversible power from the external source such as to exhaust said amount (NRJ_remaining/Dist_remaining) in a second step, according to the difference between said two consumption rates (Δratio); deciding to select the execution of a function C that enables control of supply from the internal source of reversible power in order to increase the electric operation and/or the execution of the function C with a function D that enables control of supply from the internal source of reversible power in order to increase the load shedding of the heat engine.
(FR) La présente invention concerne un procédé d'alimentation d'un groupe motopropulseur hybride pour un véhicule hybride rechargeable à partir d'une source interne d'énergie irréversible et d'une source interne d'énergie réversible qui est rechargeable en puisant directement ou indirectement dans la source interne d'énergie irréversible et par apport d'une quantité finie d'énergie réversible provenant d'une source externe. Selon l'invention, pendant le roulage du véhicule : dans une première étape, on estime le taux de consommation de la quantité consommée en énergie réversible provenant de la source externe (NRJ_consommée/Dist_depuis_recharge), on estime le taux de consommation de la quantité restante en énergie réversible provenant de la source externe de manière à épuiser ladite quantité (NRJ_restante/Dist_restante) dans une seconde étape, en fonction de la différence entre ces deux taux de consommation (Aratio), on décide de choisir l'exécution d'une fonction C qui permet de commander une alimentation à partir de la source interne d'énergie réversible de façon à augmenter le roulage électrique et/ou l'exécution de la fonction C avec une fonction D qui permet de commander une alimentation à partir de la source interne d'énergie réversible de façon à augmenter le délestage du moteur thermique.
