エネルギ蓄積装置の充電率(SoC)がEV始動SoC閾値(SoCEV-start)よりも小さいときは常にエンジンを始動させてハイブリッド電気自動車(HEV)モードで車両を始動させるように車両が制御され、
エネルギ蓄積装置の充電率(SoC)がEV始動SoC閾値(SoCEV-start)よりも大きいときは車両が電気(EV)モードで始動させるように制御され、
EV始動SoC閾値(SoCEV-start)は、
充電率(SoC)がSoC最小レベル(SoCmin)に達してエンジンがスタートする前に車両が電気(EV)モードで所定距離だけ走行可能にするのに十分な値、または
充電率(SoC)がSoC最小レベル(SoCmin)に達する前に車両が電気(EV)モードで所定時間だけ走行可能にするのに十分な値であることを特徴とする制御装置。
