To provide a vehicle periphery monitoring device and a method for coping with change of a peripheral landform in travel by a vehicle.SOLUTION: A vehicle periphery monitoring device 100 comprises: a plurality of sound sensors 102 which are arranged on different positions on a vehicle, collect a sound from a periphery for generating sound collection data; an acoustic signal processing part 110 for receiving the sound collection data, detecting a target sound indicating a peripheral vehicle and a generation position thereof on the basis of the sound collection data, for generating peripheral vehicle position data; and a selection part 108 for receiving peripheral landform data indicating a landform of the periphery of the vehicle, and selecting a sound reflection body arrangement model according to the peripheral landform data from a plurality of sound reflection body arrangement models, in which the sound reflection body arrangement models indicate arrangement of a sound reflection body related to a different landform, respectively. The acoustic signal processing part 110 detects a generation position of the target sound on the selected sound reflection body arrangement model.SELECTED DRAWING: Figure 1
【課題】車両走行中の周辺地形の変化に適応できる車両周辺監視装置および方法を提供する。【解決手段】車両周辺監視装置100は、車両の互いに異なる位置に配置され、それぞれが周囲から収音して収音データを生成する複数の音センサ102と、収音データを受け、収音データに基づいて周辺車両を示す目的音およびその発生位置を検出し、周辺車両位置データを生成する音響信号処理部110と、車両周辺の地形を示す周辺地形データを受け、複数の音反射体配置モデルから周辺地形データに応じた音反射体配置モデルを選択し、複数の音反射体配置モデルは、それぞれが異なる地形に関して音反射体の配置を示すものである、選択部108と、を備える。音響信号処理部110は、選択された音反射体配置モデルのもとで目的音の発生位置を検出する。【選択図】図1
