To perform an appropriate preliminary operation according to the situation around a target object.SOLUTION: A first preliminary operation control unit performs a first preliminary operation in which the first preliminary operation is suppressed when the degree of approach between a target object and a vehicle satisfies a second condition and when a specific condition is satisfied. A second preliminary operation control unit performs a second preliminary operation in which the second preliminary operation is suppressed when the degree of approach between the target object and the vehicle satisfies a third condition, when no space where the vehicle can travel is determined to be present in both travel paths on the lateral sides of the target object after avoiding contact by steering at the time point when the third condition is satisfied, and when the specific condition is satisfied. The specific condition is that the vehicle encounters a situation where the vehicle needs to accelerate.SELECTED DRAWING: Figure 1 【課題】対象物体の周辺状況に応じた適切な予備動作を行うこと。【解決手段】第１予備動作制御部は、前記対象物体と前記車両との接近度合いが第２条件を満たし、且つ前記特定条件を満たす場合、第１予備動作を抑制した第１予備動作を行う。第２予備動作制御部は、前記対象物体と前記車両との接近度合いが第３条件を満たし、前記第３条件が満たされた時点において、前記対象物体の側方の走路のいずれにも前記操舵による回避を行った後に進行可能なスペースが存在しないと判定され、前記特定条件が満たした場合に、第２予備動作を抑制した第２予備動作を行う。前記特定条件は、加速が必要とされる場面に前記車両が遭遇していることである。【選択図】図１
