VEHICLE CONTROL SYSTEM

To appropriately execute adaptive cruise control according to a situation of poor visibility.SOLUTION: A vehicle control system according to the present invention includes: an external information acquisition device capable of acquiring the presence of a preceding vehicle and an inter-vehicle distance; a vehicle speed acquisition device capable of acquiring a travel speed of an own vehicle; and a control device capable of executing adaptive cruise control of the own vehicle. The control device is capable of calculating a poor visibility degree for evaluating poor visibility in front of the own vehicle. When the calculated value of the poor visibility degree is equal to or greater than a prescribed first poor visibility degree threshold, the control device prohibits the acceleration of the own vehicle and permits constant speed travel of the own vehicle in the adaptive cruise control.SELECTED DRAWING: Figure 1 【課題】視界不良の状況に応じてアダプティブクルーズ制御を適切に実行する。【解決手段】本発明の車両制御システムは、先行車の存在及び車間距離を取得可能とする外部情報取得装置と、自車両の走行速度を取得可能とする車速取得装置と、自車両のアダプティブクルーズ制御を実行可能とする制御装置とを有し、制御装置が、自車両の前方の視界不良を評価するための視界不良度を算出可能とし、制御装置が、視界不良度の算出値が所定の第１視界不良度閾値以上である場合に、アダプティブクルーズ制御における自車両の加速を禁止し、かつ自車両の定速走行を許可する。【選択図】図１
