To provide a travel control device capable of appropriately allowing a vehicle to perform an operation in response to a peripheral state of the vehicle.SOLUTION: A travel control device performs: detecting a rear vehicle traveling in the periphery of a vehicle from peripheral data to be output by sensors mounted on the vehicle in response to a peripheral state of the vehicle; controlling the travel of the vehicle so as to keep a predetermined or more interval from the detected rear vehicle; allowing the vehicle to perform a first operation when the interval between the vehicle and the rear vehicle is greater than an interval threshold; allowing the vehicle to perform a second operation with a larger contribution to the safety travel of the vehicle compared with the first operation when the interval is smaller than the interval threshold; setting the interval threshold to a first value when the travel state of the vehicle does not satisfy a predetermined interval reduction condition to reduce the interval; and setting the interval threshold to a second value smaller than the first value when the travel state of the vehicle satisfies the interval reduction condition.SELECTED DRAWING: Figure 6

    【課題】車両の周辺状況に応じて適切に車両に動作を実行させることができることができる走行制御装置を提供する。【解決手段】走行制御装置は、車両に搭載されるセンサが車両の周辺状況に応じて出力する周辺データから、車両の周辺を走行する後方車両を検出し、検出された後方車両から所定以上の間隔を保つように車両の走行を制御し、車両と後方車両との間隔が間隔閾値よりも大きい場合に、車両に第1の動作を実行させ、間隔が間隔閾値よりも小さい場合に、車両に第1の動作よりも車両の安全走行への寄与の大きい第2の動作を実行させ、車両の走行状況が間隔の縮小を生じ得る所定の間隔縮小条件を満足しない場合、間隔閾値を第1の値に設定し、車両の走行状況が間隔縮小条件を満足する場合、間隔閾値を第1の値よりも小さい第2の値に設定する。【選択図】図6
