Abstract
【解決手段】ハイブリッド車両は、二輪駆動から四輪駆動に切り換える条件である四輪駆動条件を設定する手段と、車両の乗員により操作され、オン状態となることをもって回転電機のみを動力源とするEV走行を車両に行わせるEVスイッチとを備えている。四輪駆動条件設定手段は、EVスイッチがオン状態の場合(S102)には、オフ状態の場合に比べて、車両が四輪駆動で動作する領域が縮小するよう四輪駆動条件を変更する(S114)。車両の乗員がEVスイッチを操作することにより選択されたEV走行時においては、通常の走行時に比べて、四輪駆動で動作する領域が縮小し、その分、二輪駆動で動作する領域が拡大する。これにより、車両が二輪駆動で動作する頻度が高くなり、電力消費が抑制される。
