To improve communication efficiency when vehicle information such as position information of each vehicle is transmitted to a management server via a mobile communication network.SOLUTION: A vehicle information transmission device mounted on a vehicle includes an information exchange unit that sends and receives vehicle information via vehicle-to-vehicle communication and retains the received vehicle information for a certain period of time, and a transmission unit that transmits the vehicle information held by the information exchange unit to the management server via a mobile communication network at a vehicle information transmission timing for transmitting the vehicle information to the management server, and the transmission unit transmits a transmission completion notification indicating that the vehicle information has been transmitted to the management server by vehicle-to-vehicle communication, and when the transmission unit has received the transmission completion notification from another vehicle by vehicle-to-vehicle communication, the transmission unit delays the vehicle information transmission timing.SELECTED DRAWING: Figure 2

    【課題】各車両の位置情報等の車両情報を移動通信ネットワークを介して管理サーバへ送信する際の通信効率の向上を図る。【解決手段】車両に搭載される車両情報送信装置は、車車間通信により車両情報を送受し、受信した車両情報を一定期間保持する情報交換部と、車両情報を管理サーバへ送信する車両情報送信タイミングにおいて前記情報交換部が保持する車両情報を、移動通信ネットワークを介して前記管理サーバへ送信する送信部と、を備え、前記送信部は、前記管理サーバへ車両情報を送信したことを示す送信完了通知を車車間通信により送信し、前記送信部は、車車間通信により他の車両から前記送信完了通知を受信した場合に、前記車両情報送信タイミングを遅らせる。【選択図】図2
