To provide a fraud detection rule update method capable of updating rules which are the standard for detecting invalid frames in an in-vehicle network system as needed.SOLUTION: The fraud detection rule update method includes the steps of: performing judgment of conformity of a rule for a message based on the fraud detection rules; inquiring of an external device outside the in-vehicle network system whether or not the fraud detection rule has been updated; receiving the updating fraud detection rule and delivery data when there is an update of the fraud detection rule, and determining if the vehicle is running; determining if the type information indicates a drive system network related to the driving when it is determined that the vehicle is running; prohibiting performing update processing by the fraud detection rule for update when the type information indicates a drive system network related to the driving; and updating the fraud detection rule to the fraud detection rule for the update when the type information does not indicate the drive system network related to the driving.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為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】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い、車載ネットワークシステムの外部の外部装置へ不正検知ルールの更新の有無を問合せ、不正検知ルールの更新がある場合、更新用不正検知ルールと、配信データを受信し、車両が走行しているかを判定し、車両が走行していると判定した場合に、種別情報が走行に関連する駆動系のネットワークを示しているかを判定し、種別情報が走行に関連する駆動系のネットワークを示している場合には、更新用不正検知ルールによる更新処理を行わず、)種別情報が走行に関連する駆動系のネットワークを示していない場合には、不正検知ルールを更新用不正検知ルールへと更新する。【選択図】図1
