To provide a lane change assistance device for a vehicle, which is able to appropriately make determination for a lane change execution condition.SOLUTION: A lane change assistance device according to the present invention selects a three-dimensional object satisfying a first condition, as a determination-target candidate three-dimensional object, with a first predetermined number as a limit. When execution of lane change assistance control is requested, the device selects a determination-target candidate three-dimensional object satisfying a second condition, as a determination-target three-dimensional object, with a second predetermined number as a limit. In addition, if a condition for lane change execution is satisfied for the determination-target three-dimensional object, the device executes the lane change assistance control. The device according to the present invention determines, as a recognized three-dimensional object satisfying the first condition, a three-dimensional object that is located close to the own vehicle and has an estimated predetermined reach time or less in terms of estimated reach time, which is an estimated time taken for the object to reach the own vehicle.SELECTED DRAWING: Figure 12

    【課題】適切な車線変更実行条件判定を行うことができる車両の車線変更支援装置を提供する。【解決手段】本発明の車線変更支援装置は、第1条件を満たす立体物を第1の所定数を限度として判定対象候補立体物として選択し、車線変更支援制御の実行が要求されたときに第2条件を満たす判定対象候補立体物を第2の所定数を限度として判定対象立体物として選択すると共に判定対象立体物について車線変更実行条件が満たされている場合、車線変更支援制御を実行する。本発明の装置は、自車両に接近する立体物であって且つ自車両に到達するまでに要すると予測される時間である到達予測時間が所定到達予測時間以下である立体物を第1条件を満たす認識立体物であると判定する。【選択図】図12
