PROBLEM TO BE SOLVED: To provide a pedestrian detection device for a vehicle capable of accurately detecting a pedestrian at a place outside a viewable area.SOLUTION: The pedestrian detection device for a vehicle includes: a reception unit 10 for receiving a radio signal transmitted from a mobile communication terminal T with predetermined transmission power; a signal processing unit 12 for generating average reception power of the received radio signal; a distance estimation unit 14 for estimating a relative distance on the basis of a propagation loss; a velocity estimation unit 16 for estimating a relative velocity v on the basis of a time change of the relative distance; and a notification unit 18 for notifying a driver in the self-vehicle of an approach of a pedestrian, when collision of the self-vehicle and the mobile communication terminal is estimated on the basis of the relative distance d and the relative velocity v.
【課題】見通し外の位置の歩行者を精度よく検出可能な車両の歩行者検出装置の提供。【解決手段】移動通信端末Tから所定の送信電力で送信された無線信号を受信する受信部10と、受信無線信号の平均受信電力を生成する信号処理部12と、伝搬損失に基づいて相対距離を推定する距離推定部14と、相対距離の時間変化に基づいて相対速度vを推定する速度推定部16と、相対距離d及び相対速度vに基づいて、自車両と移動通信端末との衝突が予想された場合に、歩行者の接近を自車両ドライバに報知する報知部18とを有する。【選択図】図2
