Title
(EN) OPERATION OF AN ELECTRICAL MACHINE OF A HYBRID ELECTRIC VEHICLE ACCORDING TO THE STATE OF A JAW CLUTCH
(FR) CONTROLE D'UNE MACHINE ELECTRIQUE DE VEHICULE HYBRIDE SUIVANT L'ÉTAT D'UN ACCOUPLEMENT A CRABOT
Abstract
(EN)
The invention relates to a strategy for operating an electrical machine (2) connected to the wheels (10) of a hybrid electric vehicle by a jaw clutch system (6) comprising a device for detecting the state thereof, the vehicle implementing a torque control method for controlling the electrical machine (2) with a torque set point value (20) to synchronise the speeds of the two elements of the clutch (6) to be interconnected in preparation for closing the clutch, this strategy being distinguished in that it allows the torque of the electrical machine (2) to be controlled if the jaw clutch (6) is detected to be open, if the torque applied by the electrical machine (2) is higher than a torque threshold and if the speed difference between the two elements of the jaw clutch (6) is higher than a speed threshold (SV).
(FR)
L'invention a pour objet une stratégie de contrôle d'une machine électrique (2) reliée par un système d'accouplement à crabot (6) comportant un dispositif de détection de son état, à des roues (10) d'un véhicule automobile hybride, ce véhicule mettant en œuvre une régulation en couple de la machine électrique (2), délivrant une consigne de couple (20) pour synchroniser les vitesses des deux éléments à relier de l'accouplement (6) afin de préparer sa fermeture, cette stratégie étant remarquable en ce qu'elle autorise la régulation en couple de la machine électrique (2) si la détection de l'état de l'accouplement à crabot (6) indique une ouverture, si le couple appliqué par la machine électrique (2) est supérieur à un seuil de couple, et si l'écart de vitesse des deux éléments de l'accouplement à crabot (6) est supérieur à un seuil de vitesse (SV).
