To provide an obstacle detection device that can avoid hindrance due to interference while maintaining carrier wave transmission intervals as constant as possible by accurately determining interference caused by carrier waves transmitted by another vehicle.SOLUTION: An obstacle detection device according to the present disclosure includes transmission/reception control means, detection point identifying means, and ghost likelihood evaluation means. The transmission/reception control means causes a plurality of transceivers to sequentially transmit carrier waves based on a predetermined transmission order. When the transceivers receive the carrier waves, the detection point identifying means sequentially identifies detection points indicating the coordinates of the detected obstacle based on a time difference from the transmission of the carrier waves until the transceivers receive the carrier waves. The ghost likelihood evaluation means evaluates ghost likelihood which indicates the likelihood that a detection point identified by the detection point identification means may be a ghost due to reception of a carrier wave transmitted by another vehicle different from the vehicle.SELECTED DRAWING: Figure 4

    【課題】本開示は、他の車両が送信した搬送波による干渉を確度良く判定することにより、搬送波の送信間隔をできるだけ一定に維持しつつ、干渉による妨害を回避することができる障害物検知装置を提供する。【解決手段】本開示に係る障害物検知装置は、送受信制御手段、検知点特定手段及びゴースト尤度評価手段を備える。送受信制御手段は、複数の送受信器に所定の送信順に基づいて搬送波を順次送信させる。検知点特定手段は、送受信器が搬送波を受信した場合に、搬送波の送信から送受信器が搬送波を受信するまでの時間差に基づいて、検知した障害物の座標を示す検知点を順次特定する。ゴースト尤度評価手段は、検知点特定手段が特定した検知点が、車両とは異なる他の車両が送信した搬送波の受信によるゴーストであることの尤もらしさを示すゴースト尤度を評価する。【選択図】図4
