- オルタネータ(3)と車両の電力ネットワーク(2)とに接続された第1のバッテリー(7)を搭載する自動車を管理する方法において、前記オルタネータが、厳密に正の低オルタネータ電圧(Valt_basse)または少なくとも低オルタネータ電圧よりも厳密に高い高オルタネータ電圧(Valt_haute)のいずれかで動作するように制御可能であり、前記高オルタネータ電圧(Valt_haute)で電力供給された瞬間であった場合には、前記第1のバッテリー(7)が吸収することが可能な前記電位再充電電流の前記強度(I(SOC))を推定し、前記オルタネータ(3)の現在の回転速度(ω)と、前記ネットワークにおいて出力された効果的に消費された電流(Ires)の強度とに対応して、第1のオルタネータ収率(Rend1)を推定し、前記オルタネータの前記現在の回転速度、および前記バッテリーの前記電位再充電電流の前記強度(I(SOC))と前記消費された電流(Ires)との和(I(SOC)+Ires)に対応する第2のオルタネータ収率(Rend2)を推定し、前記第2の収率と前記第1の収率との差が第1のしきい値(Δ)よりも高い場合、前記高オルタネータ電圧(Valt_haute)をかける、方法。
- 前記オルタネータの前記回転速度と前記オルタネータを駆動するエンジンの回転速度の駆動比を変動させ、それにより、少なくとも前記エンジンの回転速度の範囲について前記第2の収率と前記第1の収率の前記差が増大する、請求項9に記載の方法。
