The invention relates to a method for managing a motor vehicle provided with a first battery connected to an alternator and to an electrical network of the vehicle, the alternator being drivable so as to operate either at a strictly positive low alternator voltage (Valt_basse) or at a high alternator voltage (Valt_haute) strictly higher than the low alternator voltage, wherein the method comprises estimating the strength (I(SOC)) of the potential recharging current that the first battery could absorb if it was, at that moment, powered by the high alternator voltage (Valt_haute). The method further comprises estimating a first alternator yield (Rend1) corresponding to the current speed of rotation (omega) of the alternator, and to the strength of the consumed current (Ires) actually fed into the network, estimating a second alternator yield (Rend2) corresponding to the current speed of rotation of the alternator and to the sum of the strengths (I(SOC)+Ires) of the potential recharging current (I(SOC)) of the battery and of the consumed current (Ires), and imposing a high alternator voltage if the difference between the first yield and the second yield is higher than a first threshold (Delta). |
