Zusammenfassung:	To hinder fuel consumption by allowing advancement via motor drive without restarting an engine due to idling stop control in a case where a preceding vehicle advances a little and stops again while the idling stop control is operating during constant-speed travel inter-vehicle distance control (ACC) and the own vehicle is stationary.SOLUTION: If an acceleration α at which a preceding vehicle moves is lower than a predetermined value αt when idling stop control is operating during ACC operation, it is determined that the preceding vehicle moves only a little, and the own vehicle is advanced by drive control, which uses ISG9 as a motor, without restarting an engine. This prevents fuel from being consumed unnecessarily due to engine restart resulting from the idling stop control.SELECTED DRAWING: Figure 1 【課題】定速走行車間距離制御（ＡＣＣ）の作動中にアイドリングストップ制御が作動し、自車両が停車している状態で、先行車両がわずかに前進して再度停車するような場合に、アイドリングストップ制御によるエンジン再始動は行わずにモータ駆動により前進するようにして燃料消費を抑える。【解決手段】ＡＣＣ作動中でアイドリングストップ制御が作動中に、先行車両が移動するときの加速度αが所定値αｔより小さければ、先行車両は少ししか移動しないと判断し、エンジンを再始動することなくＩＳＧ９をモータとして駆動制御して自車両を前進させる。これにより、アイドリングストップ制御によるエンジン再始動により燃料が無駄に消費されることを抑制する。【選択図】図１
