PROBLEM TO BE SOLVED: To provide an unauthorized frame handling method that can perform proper handling when an unauthorized data frame is detected in an on-vehicle network system.SOLUTION: An unauthorized detection ECU 100 is connected to a bus and inspects a frame appearing on the bus, the bus being used to deliver frames by plural electronic control units (ECU) in an on-vehicle network system. In a case where the unauthorized detection ECU 100 detects an unauthorized frame which is not matched with a predetermined rule (N in step S1003), the following unauthorized frame handling method is used. That is, the unauthorized detection ECU 100 executes prevention processing (error frame transmission) for preventing ECU from executing processing according to the unauthorized frame (step S1007) when a predetermined prevention condition is satisfied (Y in step S1006), but does not execute the prevention processing when the predetermined prevention condition is not satisfied.SELECTED DRAWING: Figure 12

    【課題】車載ネットワークシステムにおいて不正なデータフレームを検出した場合に適切な対処を可能とする不正フレーム対処方法を提供する。【解決手段】車載ネットワークシステムにおける複数の電子制御ユニット(ECU)がフレームの授受に用いるバスに接続され、当該バス上に現れるフレームを検査する不正検知ECU100は、所定ルールに適合しない不正フレームを検知した場合(ステップS1003でN)において、所定阻止条件が満たされるときには(ステップS1006でY)、当該不正フレームに従った処理をECUが実行することを阻止する阻止処理(エラーフレーム送信)を実行し(ステップS1007)、所定阻止条件が満たされないときには阻止処理を実行しない不正フレーム対処方法を用いる。【選択図】図12
