To perform an appropriate operation according to the situation around a target object.SOLUTION: A driving assistance device comprises: a braking control unit that stops a vehicle when the degree of approach between a target object and the vehicle satisfies a first condition; a first preliminary operation control unit that performs a first preliminary operation when the degree of approach satisfies a second condition and when a space where the vehicle can travel is determined to be present in one of travel paths on the lateral sides of the target object at the time point when the second condition is satisfied or near the time point; and a second preliminary operation control unit that performs a second preliminary operation when the degree of approach satisfies a third condition and when no above-mentioned space is determined to be present at the time point when the third condition is satisfied. At the time point when the degree of approach satisfies the third condition or near the time point, when the above-mentioned space is determined to be present and an interference object interfering with the above-mentioned space is estimated to be present when assuming that the vehicle approaches the target object, the second preliminary operation or the first preliminary operation is executed.SELECTED DRAWING: Figure 1 【課題】対象物体の周辺状況に応じた適切な動作を行うこと。【解決手段】対象物体と車両との接近度合が第１条件を満たす場合に、車両を停止させる制動制御部と、接近度合が第２条件を満たし、且つ第２条件が満たされた時点または当該時点付近において、対象物体の側方の走路のいずれかに進行可能なスペースが存在すると判定される場合に、第１予備動作を行う第１予備動作制御部と、接近度合が第３条件を満たし、且つ、第３条件が満たされた時点において、上記のスペースが存在しないと判定される場合に、第２予備動作を行う第２予備動作制御部と、を備え、接近度合が第３条件を満たした時点または当該時点付近において、上記のスペースが存在すると判定し、且つ車両が対象物体に近づいたと想定した場合に上記のスペースに干渉する干渉物体が存在すると推定した場合、第２予備動作または第１予備動作が実行される。【選択図】図１
