Abstract (en)

[origin: WO2022218660A1] The invention relates to a method for operating a power train (4) of a motor vehicle, the power train (4) comprising at least one internal combustion engine (6), a device (12) for injecting a fuel into the internal combustion engine (6), an electrical current generator (14) which is rotated by the internal combustion engine (6) and is capable of recharging an electrical storage device (12) which is a component of the power train (4), said power train also comprising an electric motor (10) intended to be powered by the electrical storage device (12), the method comprising at least one first step during which the generator (14) brings the internal combustion engine (6) to a predefined operating point when a state of charge of the storage device (12) is at least equal to or less than a minimum charge threshold.
