PROBLEM TO BE SOLVED: To provide a monitor system capable of notifying a piece of proper information depending on a security status of own device to an external unit at an appropriate timing.SOLUTION: An ECU 14 is configure to execute a first determination to determine whether a frame is proper/improper based on a result of a message authentication relevant to a frame received from a CAN 24, and a second determination to determine whether the frame is proper/improper based on the mode of the frame and a predetermined rule. The ECU 14 is configured to change the priority the content or information to be notified to a vehicle monitoring server 100 depending on combination of the result of the first determination and the result of the second determination.SELECTED DRAWING: Figure 1
【課題】自装置のセキュリティ状態に応じた適切な内容またはタイミングで、外部装置への通報を実現する。【解決手段】ECU14は、CAN24から受信したフレームに対するメッセージ認証の結果に基づいてフレームが不正かを判定する第1判定と、フレームの態様と予め定められたルールとに基づいてフレームが不正かを判定する第2判定とを実行する。ECU14は、第1判定の結果と第2判定の結果との組み合わせに応じて、車両監視サーバ100へ通報する内容または通報の優先度を変更する。【選択図】図1
