PROBLEM TO BE SOLVED: To provide collision determination device capable of improving the accuracy of collision determination, and a collision determine method.SOLUTION: A driving support ECU 20 includes: an acquisition part 21 that acquires a piece of radar detect information from a radar sensor 31; a filter processing part 22; a filter setting part 28 that sets filter characteristics; and a target information detection part 23 that detects the position of a target using the radar detect information after the filter processing. The driving support ECU 20 also includes: a target track estimation part 24 that estimates a track of the target; an own vehicle track estimation part 25 that estimates the track of an own vehicle; and a collision determination part 26 that executes a collision determination of the own vehicle and the target based on the track of the target and the track of the own vehicle. When the time to detect detectable position of the target is short, the filter setting part 28 sets the filter characteristics so that the degree of possibility to reduce the changes of the radar detection information compared to the case when the time to detect detectable position of the target is long.SELECTED DRAWING: Figure 1 【課題】衝突判定の正確性を向上させることができる衝突判定装置及び衝突判定方法を提供すること。【解決手段】運転支援ＥＣＵ２０は、レーダセンサ３１からレーダ検知情報を取得する取得部２１と、フィルタ処理部２２と、フィルタ特性を設定するフィルタ設定部２８と、フィルタ処理されたレーダ検知情報を利用して、物標の位置を検出する物標情報検出部２３とを備える。運転支援ＥＣＵ２０は、また、物標の進路を推定する物標進路推定部２４と、自車両の進路を推定する自車進路推定部２５と、物標の進路と、自車両の進路に基づき、自車両と前記物標との衝突判定を実行する衝突判定部２６と、を備える。フィルタ設定部２８は、物標の位置を検出可能な検出可能時間が短い場合には、長い場合と比較して、レーダ検知情報の変化を抑制するなまし度合いが大きくなるようにフィルタ特性を設定する。【選択図】 図１
