Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a control device for a vehicle capable of further improving fuel economy during coasting.SOLUTION: A control unit reads in various types of sensor signals (Step S1) and then, determines whether a coasting condition is satisfied (Step S2). When a determination that the coasting condition is satisfied is made, if a shift position is in an M range (Yes in Step S4), the control unit executes a first coasting mode (Step S6). When a situation where speed change of a vehicle is less than a predetermined value is continued for a predetermined period (Yes in Steps S7-S9), transfer to a second coasting mode is made (Step S10). The first coasting mode is a control mode of causing an engine to become an idling state and causing an automatic transmission to become a neutral state. The second coasting mode is a control mode of causing the engine to become an idling stop state while maintaining the neutral state of the automatic transmission.SELECTED DRAWING: Figure 2 【課題】コースト走行時におけるさらなる燃費の向上を図ることができる車両の制御装置を提供する。【解決手段】コントロールユニットは、各種センサ信号の読み込みを行い（ステップＳ１）、次に、コースト走行条件が成立したか否かを判断する（ステップＳ２）。コースト走行条件が成立したと判断の場合であって、シフトポジションがＭレンジにある場合には（ステップＳ４：Ｙｅｓ）、第１コーストモードを実行し（ステップＳ６）、車両の速度変化が所定値未満の状態が所定期間継続したときに（ステップＳ７〜Ｓ９：Ｙｅｓ）、第２コーストモードでの制御に移行する（ステップＳ１０）。第１コーストモードは、エンジンをアイドル状態とするとともに、自動変速機をニュートラル状態とする制御モードである。第２コーストモードは、自動変速機のニュートラル状態を維持しながら、エンジンをアイドルストップ状態とする制御モードである。【選択図】図２
