PROBLEM TO BE SOLVED: To provide a gateway device which allows an electronic control unit (ECU) that does not perform a necessary process for updating firmware to properly update firmware.SOLUTION: A gateway 300 is connected to a bus used by a plurality of ECUs 100a-100d mounted on a vehicle for communication and includes; receiver unit configured to receive firmware update information including update firmware applicable to one of the plurality of ECUs 100a-100d from a server 500, an external device to the vehicle; and a control unit configured to a determine, on the basis of information on an ECU to which the update firmware is to be applied, whether the ECU satisfies a predetermined condition or not, and to let the ECU perform a predetermined process associated with updating of firmware when the predetermined condition is satisfied, or let another ECU perform the predetermined process when the predetermined condition is not satisfied.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】車両に搭載された複数のECU100a〜100dが通信に用いるバスに接続されたゲートウェイ300は、車両外の外部装置としてのサーバ500から、複数のECU100a〜100dのうち1つのECU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ECUの情報に基づいてそのECU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ECU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ECU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
