To provide a vehicle surroundings monitoring device, a vehicle surroundings monitoring method, and a program that store information pertaining to a location of obstacles in the surroundings measured in the past when a vehicle's power switch is turned off, with a small storage capacity.SOLUTION: A periphery monitoring device for vehicles includes: a distance measurement unit that measures coordinates of an obstacle based on a first time point when a transmission wave is output, a position of a vehicle at the first time point, a second time point when a reflected wave of the transmission wave is detected, and a position of the vehicle at the second time point; a vehicle status detection unit that detects a status of a power supply of the vehicle; an information compressing unit that compresses the coordinates of the obstacle measured by the distance measurement unit into lower resolution information when the power supply of the vehicle is turned off; an information writing unit that writes the compressed coordinates to a storage device; an information reading unit that reads the written coordinates from the storage device when the power supply of the vehicle is turned on; and a contact determination unit that determines contact between the vehicle and the obstacle using the coordinates read by the information reading unit.SELECTED DRAWING: Figure 8

    【課題】車両の電源スイッチを切断した際に、過去に計測された周囲の障害物の位置に係る情報を、少ない記憶容量で記憶する車両用周囲監視装置、車両用周囲監視方法およびプログラムを提供する。【解決手段】車両用周囲監視装置は、送信波を出力した第1の時刻と、第1の時刻における車両の位置と、送信波の反射波を検出した第2の時刻と、第2の時刻における車両の位置とに基づいて、障害物の座標を計測する測距部と、車両の電源の状態を検出する車両状態検出部と、車両の電源が切断された際に、測距部が計測していた障害物の座標を、より分解能が低い情報に圧縮する情報圧縮部と、圧縮された座標を記憶装置に書き込む情報書込部と、車両の電源が投入された際に、記憶装置から、書き込まれた座標を読み出す情報読出部と、情報読出部が読み出した座標を用いて、車両と障害物との接触を判定する接触判定部とを備える。【選択図】図8
