Abstract:
(DE) Die Erfindung betrifft ein Verfahren zum Ermitteln von Freilaufphasen (PhiFi) einer mit einem Freilauf (11) an eine Brennkraftmaschine (112) gekoppelten elektrisehen Maschine (114), die die Schritte Erfassen eines zeitlichen Verlaufs eines Phasensignal (121) der elektrischen Maschine (114), Ermitteln eines zeitlichen Verlaufs einer Drehzahl (122) der elektrischen Maschine (114) aus dem Phasensignal (121) und Ermitteln zumindest einer Freilaufphase (PhiFi) durch Auswerten der zeitlichen Änderung der Drehzahl (122) der elektrischen Maschine (1 14) zumindest im Zeitbereich einer abfallenden Flanke (124) einer oszillierenden Drehzahlschwingung der elektrischen Maschine (114) aufweist. 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 freewheel phases (PhiFi) of an electrical machine (114) coupled, by means of a freewheel mechanism (11), 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) from the phase signal (121) and determining at least one freewheel phase (PhiFi) by evaluating the temporal variation of the speed (122) of the electrical machine (114) at least in the time domain of a negative slope (124) of an oscillating speed oscillation of the electrical machine (114). 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 des phases de roue libre (PhiFi) d’une machine électrique (114) couplée à un moteur à combustion interne (112) par l’intermédiaire d’une roue libre (11), 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) à partir du signal de phase (121), et à déterminer au moins une phase de roue libre (PhiFi) par évaluation de la variation temporelle de la vitesse de rotation (122) de la machine électrique (114) au moins au cours d’un intervalle de temps correspondant à un flanc descendant (124) d’une oscillation de vitesse de rotation de la machine électrique (114). L'invention concerne par ailleurs une unité de calcul correspondante (118) conçue pour mettre en œuvre le procédé, ainsi qu’un programme informatique correspondant.
