PROBLEM TO BE SOLVED: To provide a vehicle control system capable of inhibiting a variation in deceleration at the time of braking.SOLUTION: The vehicle control system includes a clutch that connects or disconnects an engine with driving wheels, and a control unit. When activation of a brake is not detected, the control unit performs first traveling control of allowing a vehicle to travel with the clutch disengaged and the engine stopped. When a vehicle speed is equal to or smaller than a threshold and activation of the brake is detected, the control unit performs second traveling control of allowing the vehicle to travel with the clutch disengaged and the engine stopped. When the first traveling control is performed (Y at step S10), if activation of the brake is detected (Y at step S20), as long as engagement of the clutch is predicted to be completed before the vehicle speed becomes equal to or smaller than the threshold (N at step S40), the control unit initiates clutch engagement control (step S60). If the vehicle speed is predicted to become equal to or smaller than the threshold before engagement of the clutch is completed (Y at step S40), the control unit does not initiate the engagement control (step S50).SELECTED DRAWING: Figure 3 【課題】制動時の減速度の変動を抑制することができる車両制御装置を提供する。【解決手段】エンジンと駆動輪とを接続あるいは遮断するクラッチと、制御部と、を備え、制御部は、ブレーキオンが検出されていない場合にクラッチが開放し、かつエンジンが停止した状態で車両を走行させる第一走行制御を実行し、車速が閾値以下でブレーキオンが検出されている場合にクラッチが開放し、かつエンジンが停止した状態で車両を走行させる第二走行制御を実行し、制御部は、第一走行制御の実行中（ステップＳ１０−Ｙ）にブレーキオンが検出された（ステップＳ２０−Ｙ）場合に、車速が閾値以下となるまでにクラッチの係合が完了すると予測される（ステップＳ４０−Ｎ）ときはクラッチの係合制御を開始し（ステップＳ６０）、クラッチの係合が完了するまでに車速が閾値以下になると予測される（ステップＳ４０−Ｙ）ときは係合制御を開始しない（ステップＳ５０）。【選択図】図３
