DETERMINING AN OPERATING MODE OF AN ELECTRICAL MACHINE COUPLED TO AN INTERNAL COMBUSTION ENGINE

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...

Beschreibung
Zusammenfassung:	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.
