VEHICLE

PROBLEM TO BE SOLVED: To avoid a restart of an internal combustion engine which has started idle-stopping not meeting the intention of a driver, and to shorten a time necessary for the restart when performing the restart meeting the intention of the driver as much as possible.SOLUTION: In a vehicle, an auxiliary motor which can drive an output shaft of an internal combustion engine is arranged different from a starting motor used for cranking for starting the internal combustion engine, in a case where idle-stopping of the internal combustion engine is started before the vehicle is stopped, the output shaft of the internal combustion engine is driven by the auxiliary motor when a pedal-in amount of a brake pedal reaches zero or a value not larger than a threshold which is approximate to zero, the rotation of the output shaft is maintained for a prescribed period of time, when the pedal-in amount of the accelerator pedal reaches the threshold or larger within the prescribed period of time, cranking for starting the internal combustion engine is performed by using the starting motor, or the drive of the output shaft of the internal combustion engine performed by the auxiliary motor is stopped.SELECTED DRAWING: Figure 3 【課題】アイドルストップを開始した内燃機関の運転者の意思に沿わない再始動を避け、また運転者の意思に沿って再始動を行うときにその再始動に要する時間をできる限り短縮する。【解決手段】内燃機関の始動のためのクランキングに用いる始動用モータとは別に、内燃機関の出力軸を駆動することが可能な補助モータを設けており、車両が停車する前に内燃機関のアイドルストップを開始した場合において、ブレーキペダルの踏込量が０または０に近い閾値以下となったとき、補助モータで内燃機関の出力軸を駆動してその回転を所定期間維持し、当該所定期間内にアクセルペダルの踏込量が閾値以上となったならば始動用モータを用いて内燃機関の始動のためのクランキングを行い、さもなくば補助モータによる内燃機関の出力軸の駆動を停止する車両を構成した。【選択図】図３
