To provide a gateway device to enable an electronic control unit (ECU) that does not perform necessary processing for firmware updates, to properly update firmware.SOLUTION: A virtual machine monitor having a function of a gateway 300 connected to a bus used for communication by a plurality of virtual machines having respective functions of a plurality of ECUs 100a to 100d mounted on a vehicle in a virtual environment, includes: a receiving unit that receives firmware update information including firmware for update to be applied to one of the plurality of virtual machines from outside the virtual environment; and a control unit that determines whether a virtual machine meets a prescribed condition based on information on the virtual machine to which firmware for update is to be applied and controls so that, if the predetermined condition is met, the virtual machine executes the predetermined process related to the firmware update, and, if the predetermined condition is not met, the predetermined process is executed by a virtual machines other than the virtual machine.SELECTED DRAWING: Figure 1

    【課題】ファームウェアの更新に必要な処理を実行しない電子制御ユニット(ECU)が適切にファームウェアの更新を行うことを可能にするためのゲートウェイ装置を提供する。【解決手段】仮想環境で車両に搭載された複数のECU100a〜100dのそれぞれの機能を有する複数の仮想マシンが通信に用いるバスに接続されたゲートウェイ300の機能を有する仮想マシンモニタは、仮想環境の外部から、複数の仮想マシンのうち1つの仮想マシンを適用対象とした更新用ファームウェアを含むファームウェア更新情報を受信する受信部と、更新用ファームウェアの適用対象の仮想マシンの情報に基づいてその仮想マシンが所定条件を満たすか否かを判定し、所定条件を満たす場合にはその仮想マシンにファームウェアの更新に関連する所定処理を実行させ、所定条件を満たさない場合には所定処理がその仮想マシン以外で実行されるように制御する制御部とを備える。【選択図】図1
