Abstract
【解決手段】内燃機関の回転に応じて生ずる負圧室の負圧を用いてブレーキ操作が補助されると共に、内燃機関が第1の条件が成立する場合に自動停止され、その後第2の条件が成立する場合に自動始動される車両の制御装置は、ブレーキ操作が行われていないか否かを判別し、内燃機関の回転数を検出し、負圧センサを用いて負圧室の負圧を検出する。また、ブレーキ操作が行われていないと判別されかつ内燃機関の回転数が閾値以上である状態が所定時間以上継続した後、負圧室の負圧に基づいて負圧センサの異常有無の仮判定を行い、異常状態との仮判定が所定回数なされた場合に、その異常状態を確定し、内燃機関の自動停止を禁止する。また、異常状態との仮判定が行われた後、上記状態が継続するか否かに応じて、仮判定で用いる上記所定時間を変更する。
