To provide a communication device, a communication method and a vehicle-to-vehicle communication system achieving more appropriate communication.SOLUTION: On-vehicle equipment 4 of an on-vehicle system 6 includes: a self-vehicle information collection unit 22 which acquires information of the self-vehicle having the loaded self-equipment; and a communication unit 24 which communicates with another vehicle existing in the periphery of the self-vehicle to transmit the information of the self-vehicle. The on-vehicle equipment further includes: a communication status information acquisition unit 43 which acquires handshake communication status information indicating whether or not another vehicle is already performing handshake communication; and a communication frequency control unit 48 which, when the other vehicle is already performing the handshake communication, changes the transmission frequency of the self-vehicle information to a second frequency which is relatively lower than the first frequency.SELECTED DRAWING: Figure 2
【課題】より適切な通信を実現する通信装置、通信方法、及び車車間通信システムを提供する。【解決手段】自身が搭載された自車両の情報を取得する自車両情報収集部22と、自車両の周辺に存在する他車両と通信し、自車両の情報を送信する通信部24と、を有した車載システム6の車載機4において、他車両が既にハンドシェイク通信を行っているか否かを示すハンドシェイク通信状況情報を取得する通信状況情報取得部43と、他車両が既にハンドシェイク通信を行っている場合に、自車両の情報の送信頻度を第1の頻度よりも相対的に低い第2の頻度へ変更する通信頻度制御部48と、を備える。【選択図】図2
