To make it less likely that at a vehicle, communication data cannot be transmitted or received due to interruption, missing, or the like of communication data while moving.SOLUTION: An external communication system 40 of a vehicle 1 includes: a plurality of communication devices 32 to 34 that transmit and receive communication data between a server device 2 and the vehicle 1 through communication paths different from each other; and a control unit 43 that controls communication by the communication devices 32 to 34. The control unit 43 sets at least one of the communication devices 32 to 34 as a main communication device that transmits and receives the communication data between the server device 2 and the vehicle 1, and sets at least one of the remainders of the communication devices 32 to 34 as a backup communication device that transmits and receives the communication data between the server device 2 and the vehicle 1.SELECTED DRAWING: Figure 3

    【課題】車両において、移動中の通信データの遮断や欠落などにより通信データの送受ができなくなることを生じ難くする。【解決手段】車両1の車外通信システム40は、サーバ装置2と車両1との間の通信データを、互いに異なる通信路を通じて送受する複数の通信装置32〜34と、複数の通信装置32〜34による通信を制御する制御部43と、を有する。制御部43は、複数の通信装置32〜34の少なくとも1つを、サーバ装置2と車両1との間での通信データを送受するメイン通信装置とし、複数の通信装置32〜34の残りの少なくとも1つを、サーバ装置2と車両1との間での通信データを送受するバックアップ通信装置とする。【選択図】 図3
