PROBLEM TO BE SOLVED: To provide a fraud detection rule updating method that can update a rule as a reference for detecting an unauthorized frame as occasion demands in an on-vehicle network system.SOLUTION: An on-vehicle network system having plural electronic control units (ECU) 100a to 100e communicating with one another through a bus, and fraud detection ECUs 400a to 400c for performing determination of adaptability of a message transmitted on the bus to a rule on the basis of a fraud detection rule uses a fraud detection rule updating method of receiving distribution data containing an updating fraud detection rule from an external server 500 of the on-vehicle network system, and updating a fraud detection rule to the updating fraud detection rule in the fraud detection ECU 400a when a predetermined updating condition is satisfied.SELECTED DRAWING: Figure 1
【課題】車載ネットワークシステムにおいて必要に応じて不正なフレームを検知するための基準となるルールの更新を可能にする不正検知ルール更新方法を提供する。【解決手段】バスを介して通信する複数の電子制御ユニット（ＥＣＵ）１００ａ〜１００ｅ、及び、バス上で送信されるメッセージについてのルールへの適合性の判定を不正検知ルールに基づいて行う不正検知ＥＣＵ４００ａ〜４００ｃを備える車載ネットワークシステムにおいて、車載ネットワークシステムの外部のサーバ５００から更新用不正検知ルールを含む配信データを受信して、所定更新条件が満たされた場合には不正検知ＥＣＵ４００ａにおいて不正検知ルールを当該更新用不正検知ルールへと更新する不正検知ルール更新方法を用いる。【選択図】図１
