Description
−第1のステップにおいて、作動状態の熱機関の消費量と休止状態の熱機関の等価消費量との差を取ることによって熱機関の燃料消費量利得を熱機関外部の他のエネルギー源とは独立にリアルタイムで決定することからなり、該等価消費量は、定められた回転数における消費量の増分と機関出力の増分の比に相当する定められた係数をもとに計算されるものであり、さらに、
−第2のステップにおいて、定められた基準および消費量利得に応じて熱機関の作動または休止を決定することからなり、該基準は、電気エネルギー回収手段の回収レベルに依存し、電気エネルギー貯蔵手段の使用が増大し熱機関ができる限り頻繁に停止されるように定められるものである、
管理方法を第1の目的とする。
a)熱機関を停止しない場合、電気機械は使用されず、熱機関の消費量は在来型車両の消費量となる。
b)期間Tに熱機関を停止した場合、その期間の車両の消費量はゼロになるが、バッテリの方は、車両の走行に必要な出力を供給するために放電する。バッテリの充電レベルを一定に保つためには、期間T+1の間にバッテリの充電を行わなければならない。その場合、機関は、車両の走行とバッテリの充電の両方のために必要な出力を供給しなければならない。
G=熱モードでの消費量−電気モードでの等価消費量
すなわち
G=[Pmth・K+b(Nmth)]−[Pmth・K/ηelec2]
ただし
Pmth=熱機関によって供給される出力
K=所定のマップによって定義される熱機関の比例係数
Nmth=熱機関の回転数
b=機関回転数Nmthのみに依存する消費量部分
ηelec=電気システムの効率
