Claims (1)
- 走行ポジションと非走行ポジションとを有する自動変速機を備える車両に搭載され、所定停止条件が成立した場合に運転が自動停止され、かつ前記自動停止後に所定再始動条件が成立した場合に再始動される内燃機関における再始動時の空燃比制御方法であって、
前記自動停止後に自動変速機の変速ポジションを判定し、
変速ポジションが非走行ポジションであることを判定した場合に、前記自動停止後の再始動時の目標吸入空気量を、走行ポジションであることを判定した場合よりも多く設定し、
前記再始動条件が成立した場合に吸入空気量が設定した目標吸入空気量となるようにして再始動を実施する内燃機関の空燃比制御方法。
