To provide an obstacle detection system in a vehicle traveling on a track and a method for the same which can detect, in high precision, a front obstacle on a track and its periphery.SOLUTION: An obstacle detection system comprises a monitoring area setting processing unit to set an obstacle monitoring area to detect an obstacle, a front obstacle monitoring unit to monitor an obstacle in the obstacle monitoring area using a sensor scanning the front of the train horizontally, and an obstacle detection unit to detect the obstacle in the obstacle monitoring area based on the monitoring result by the front obstacle monitoring unit. The front obstacle monitoring unit complements a gap between the detection areas of the sensor in a first position, using a detection region of the sensor while the train moves from the first position to a second position.SELECTED DRAWING: Figure 8 【課題】軌道上およびその周辺の前方障害物を高精度に検出することができる軌道走行車両の障害物検知システムおよび障害物検知方法を提供する。【解決手段】障害物検知システムは、障害物を検知する障害物監視エリアを設定する監視エリア設定処理部と、列車の前方を水平方向に走査するセンサーを用いて、障害物監視エリア内の障害物を監視する前方障害物監視部と、前方障害物監視部での監視結果に基づき、障害物監視エリア内の障害物を検知する障害物検知部と、を備え、前方障害物監視部は、第１の位置における前記センサーの検出領域の隙間を、列車が第１の位置から第２の位置まで移動する間におけるセンサーの検出領域で補完する。【選択図】図８
