Zusammenfassung:To provide a periphery monitoring device for a vehicle which can accurately perform recording in response to another vehicle that moves sideways.SOLUTION: A virtual boundary line continuously showing a boundary of a travel lane 60 without a defective part and a virtual circle assuming contours of tires of another vehicle 50 that travels side by side are overlapped on a lateral photographed image captured by a lateral camera 26. A recording control unit performs control so as to start recording of an image for recording in a storage when the virtual boundary line and the virtual circle cross each other. The recording control unit terminates recording of the image for recording in the storage when it is determined that a state where the virtual boundary line and the virtual circle do not cross each other and a state where a target overlapping the virtual boundary line in the lateral photographed image does not exist in an area other than a lane boundary line L continue for a prescribed time after the start of recording of the image for recording in the storage.SELECTED DRAWING: Figure 1 【課題】幅寄せしてきた他車両に対応して的確に録画をすることができる車両用周辺監視装置を得る。【解決手段】側方カメラ26により撮像された側方撮像画像に、走行レーン60の境界を欠損部なく連続して示す仮想境界線と、並走する他車両50のタイヤの輪郭を想定した仮想円とが重畳される。記録制御部は、仮想境界線と仮想円とが交わった場合に、記録用画像のストレージへの記録を開始するように制御する。また、記録制御部は、記録用画像のストレージへの記録開始後に、仮想境界線と仮想円との交わりがない状態でかつ側方撮像画像において仮想境界線と重なる物標がレーン境界線L以外は存在しない状態が所定時間継続したと判断した場合に、記録用画像のストレージへの記録を終了させる。【選択図】図1
