PROBLEM TO BE SOLVED: To provide a technology capable of transmitting detection information according to fluctuation of an amount of detection information necessary on an on-vehicle electronic controller.SOLUTION: A microcomputer 190 is configured to control a CAN I/F circuit 170, which is configured to transmit pumping current information calculated based on pumping current Ip output from an oxygen sensor mounted on a vehicle, to an engine ECU 9 through a communication wire 8. The microcomputer 190 is configured to determine whether to receive, from the engine ECU 9, CID start information indicating that detection of cylinder imbalance of an engine is started. The microcomputer 190 is configured to, when determining that the CID start information is received, transmit the pumping current information to the CAN I/F circuit 170 so as to make a transmission amount that the pumping current information is transmitted per unit time larger than a time point when the CID start information is received.SELECTED DRAWING: Figure 3

    【課題】車載電子制御装置側で必要とする検出情報の情報量の変動に応じて検出情報を送信する技術を提供する【解決手段】マイコン190は、車両に搭載された酸素センサから出力されるポンピング電流Ipに基づいて算出されたポンピング電流情報を、通信線8を介してエンジンECU9へ送信するCANI/F回路170を制御する。マイコン190は、エンジンの気筒インバランスの検出が開始されたことを示すCID開始情報をエンジンECU9から受信したか否かを判断する。マイコン190は、CID開始情報を受信したと判断した場合に、CID開始情報を受信した時点よりも、単位時間当りにポンピング電流情報を送信する送信量が多くなるようにCANI/F回路170にポンピング電流情報を送信させる。【選択図】図3
