Title (EN) OPERATION OF AN ELECTRICAL MACHINE OF A HYBRID ELECTRIC VEHICLE PRIOR TO CLOSING A JAW CLUTCH
(FR) CONTROLE D'UNE MACHINE ELECTRIQUE DE VEHICULE HYBRIDE POUR LA FERMETURE D'UN ACCOUPLEMENT A CRABOT
Abstract:
(EN) The invention relates to a strategy for operating an electrical machine (2) connected by a jaw clutch system (6) to the wheels (10) of a hybrid electric vehicle which implements a speed control method for controlling the electrical machine (2) with a synchronising speed set point value (18) in order to adjust with a margin 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 prevents the control of the speed of the electrical machine (2) in preparation for closing the jaw clutch (6) from being implemented if the speed difference between the two elements of the clutch (6) is lower than a speed threshold and if, for this electrical machine (2), the difference between the speed set point value (18) and the actual speed (16) is higher than a speed threshold.
(FR) L'invention a pour objet une stratégie de contrôle d'une machine électrique (2) reliée par un système d'accouplement à crabot (6) à des roues (10) d'un véhicule automobile hybride, ce véhicule mettant en œuvre une régulation en régime de la machine électrique (2) comportant une consigne de régime (18) de synchronisation qui ajuste avec une marge les vitesses des deux éléments à relier de l'accouplement (6) afin de préparer sa fermeture, cette stratégie étant remarquable en ce qu'elle émet une interdiction de la régulation en régime de la machine électrique (2) préparant la fermeture de l'accouplement à crabot (6), si l'écart de vitesse des deux éléments de cet accouplement (6) est inférieur à un seuil de vitesse, et si pour cette machine électrique (2) l'écart entre la consigne de régime (18) et son régime en cours (16) est supérieur à un seuil de régime.
