To provide a communication device that can avoid interference with other wireless communication, and continue wireless communication with a communication partner even when communication obstacles suddenly interfere with a wireless communication propagation path between a user and the communication partner for inter-vehicle communication or road-vehicle communication.SOLUTION: A communication device includes: performing wireless communication with a communication partner by forming a directional beam that is headed toward another vehicle of the communication partner or a road-side communication device using a directional antenna; detecting a communication obstacle entering a wireless propagation path between an own vehicle and the communication partner; detecting an edge of an outer edge configuration of the communication obstacle when the communication obstacle entering the wireless propagation path is viewed from the own vehicle direction; and performing control so that the direction of a directional beam from the directional antenna is changed from a direction toward the communication partner to a direction toward the edge of a communication obstacle when the communication obstacle enters the wireless propagation path.SELECTED DRAWING: Figure 1
【課題】他の無線通信との干渉を回避するとともに、車車間通信又は路車間通信の通信相手との間の無線通信の伝搬路に通信障害物が突然入ってきた場合でも通信相手との無線通信を継続することができる通信装置を提供する。【解決手段】指向性アンテナにより通信相手の他車両又は路側通信装置に向かう指向性ビームを形成し前記通信相手と無線通信を行う。自車両と通信相手との間の無線伝搬路に通信障害物が入ってきたことを検出する。無線伝搬路に入ってきた通信障害物を自車両方向から見たときの通信障害物の外縁形状のエッジを検出する。無線伝搬路に通信障害物が入ってきたとき、指向性アンテナによる指向性ビームの向きを通信相手に向かう向きから通信障害物のエッジに向かう向きに変更するように制御する。【選択図】図1
