Outline of Final Research Achievements	We developed an on-board sensor data transmission rate control technique for vehicle-to-vehicle wireless communication to enable the reliability of sensor data transmission and the accuracy of neighboring environment recognition in road environment recognition system for collision avoidance with driver assist function or auto pilot function that works even in condition where the penetration ratio of vehicle-to-vehicle communication function is less than 100%. We also designed a microwave radio and visible light communication hybrid control command transmission scheme for autonomous platooning systems that reliably deliver control commands from the leader vehicle even under radio jamming attack. We developed a virtual wireless LAN device software for enabling wireless LAN emulation that can be used for developing dynamic wireless systems including vehicle-to-vehicle communication systems.

Academic Significance and Societal Importance of the Research Achievements	車々間通信における車両情報の送信制御に関しては、車両の密度や通信品質に応じて動的に送信頻度や送信電力を制御する方式が提案されてきたが、車載センサ情報の共有による周辺状況把握（Cooperative Perception, CP）を対象として、センシングを行う車両の相対位置や道路構造に基づいて送信頻度を制御する方式は提案されておらず、提案方式は、CPの品質に着目した送信制御を新たに導入した点で意義をもつ。自律隊列走行において可視光通信と電波通信と併用した方式を設計し、意図的な通信妨害がある場合における通信の信頼性、並びに車両挙動までを含んだ評価を行った例はこれまでになく、学術的意義が高い。
