Title (EN) A METHOD AND SYSTEM FOR GEAR SHIFTING IN A HYBRID POWERTRAIN
(FR) PROCÉDÉ ET SYSTÈME DE CHANGEMENT DE VITESSE DANS UN GROUPE MOTOPROPULSEUR HYBRIDE
Abstract:
(EN) The invention relates to a method for gear shifting in a hybrid powertrain, comprising an internal combustion engine (2); an electric machine (6); a gearbox (8); and an energy storage unit (18) connected to the electric machine (6), wherein at least one control unit (20) is arranged in communication with the internal combustion engine (2), the electric machine (6), the gearbox (8) and the energy storage unit (18). The method comprises the steps of: determining (s101) the energy level in the energy storage unit (18); determining (s102) the acceleration ability with a subsequent gear; determining (s103) a target engine speed for the internal combustion engine (2) based on the energy level in the energy storage unit (18) and the acceleration ability; and controlling (s104) the gear shifting based on the target engine speed. The invention also relates to a system (30) for gear shifting in a hybrid powertrain (3), a vehicle (1) comprising such a system (30), a computer program (P) and a computer program product.
(FR) L'invention concerne un procédé de changement de vitesse dans un groupe motopropulseur hybride, comprenant un moteur à combustion interne (2); une machine électrique (6); une boîte de vitesses (8); et une unité de stockage d'énergie (18) connectée à la machine électrique (6), au moins une unité de commande (10) étant agencée en communication avec le moteur à combustion interne (2), la machine électrique (6), la boîte de vitesses (8) et l'unité de stockage d'énergie (18). Le procédé comprend les étapes consistant : à déterminer (s101) le niveau d'énergie dans l'unité de stockage d'énergie (18); à déterminer (s102) la capacité d'accélération avec une vitesse suivante; à déterminer (s103) une vitesse de moteur cible pour le moteur à combustion interne (2) sur la base du niveau d'énergie dans l'unité de stockage d'énergie (18) et la capacité d'accélération; et à commander (s104) le changement de vitesse sur la base de la vitesse de moteur cible. L'invention concerne également un système (30) pour le changement de vitesse dans un groupe motopropulseur hybride (3), un véhicule (1) comprenant un tel système (30), un programme informatique (P) et un produit-programme informatique.
