Title (DE) ERMITTELN EINES BETRIEBSZUSTANDS EINER AN EINE BRENNKRAFTMASCHINE GEKOPPELTEN ELEKTRISCHEN MASCHINE
(EN) DETERMINING AN OPERATING MODE OF AN ELECTRICAL MACHINE COUPLED TO AN INTERNAL COMBUSTION ENGINE
(FR) DÉTERMINATION DE L'ÉTAT DE FONCTIONNEMENT D'UNE MACHINE ÉLECTRIQUE COUPLÉE À UN MOTEUR À COMBUSTION INTERNE
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zum Ermitteln eines Betriebszustands einer an eine Brennkraftmaschine (112) gekoppelten elektrischen Maschine (114), die die Schritte Erfassen eines zeitlichen Verlaufs eines Phasensignal (121) der elektrischen Maschine (114), Ermitteln eines zeitlichen Verlaufs einer oszillierende Drehzahlschwingungen aufweisenden Drehzahl (122) der elektrischen Maschine (1 14) und Ermitteln des Betriebszustands der elektrischen Maschine (114) durch Vergleich des zeitlichen Verlaufs des Phasensignals (121) der elektrischen Maschine (114) und des zeitlichen Verlaufs der Drehzahl (n). Des Weiteren betrifft die Erfindung eine entsprechende Recheneinheit (118), die zur Durchführung des Verfahrens eingerichtet ist, sowie ein entsprechendes Computerprogramm.
(EN) The invention relates to a method for determining an operating mode of an electrical machine (114) coupled to an internal combustion engine (112), the method comprising the steps: detecting a plot against time of a phase signal (121) of the electrical machine (114); determining a plot against time of a speed (122) of the electrical machine (114), said speed having oscillating speed oscillations; and determining the operating mode of the electrical machine (114) by comparing the plot against time of the phase signal (121) of the electrical machine (114) and the plot against time of the speed (n). The invention also relates to a corresponding arithmetic unit (118), configured for carrying out the method, and to a corresponding computer programme.
(FR) La présente invention concerne un procédé pour déterminer l'état de fonctionnement d'une machine électrique (114) couplée à un moteur à combustion interne (112), le procédé comprenant les étapes consistant à détecter l'allure au cours du temps d'un signal de phase (121) de la machine électrique (114), à déterminer l'allure au cours du temps de la vitesse de rotation (122) de la machine électrique (114), présentant des oscillations de vitesse de rotation, et à déterminer l'état de fonctionnement de la machine électrique (114) par comparaison de l'allure au cours du temps du signal de phase (121) de la machine électrique (114) et de l'allure au cours du temps de la vitesse de rotation (n). L'invention concerne par ailleurs une unité de calcul correspondante (118) conçue pour mettre en œuvre le procédé, ainsi qu'un programme informatique correspondant.
