PROBLEM TO BE SOLVED: To provide an electronic control device in which a request signal for operating a control target is transmitted to a second electronic control device from a first electronic control device, and upon reception of the request signal, the second electronic control device supplies power to the control target to operate the control target until a continuation time for which the request signal is not received reaches a time-out time, and also provide a network system which can reduce power consumption without deteriorating the responsibility of the operation of the control target.SOLUTION: A first electronic control device transmits a request signal to a second electronic control device when it is determined that an operation condition for the control target is satisfied. The first electronic control device transmits, to a second electronic control device, control information with which the probability level of satisfaction of the operation condition can be determined. Upon reception of the request signal, the second electronic control device continues power supply to the control target to operate the control target until a continuation time for which the request signal is not received reaches a time-out time. The second electronic control device further changes the time-out time on the basis of the control information from the first electronic control device (S420 to S440).

    【課題】第1電子制御装置から第2電子制御装置へ制御対象を動作させる要求信号を送信し、第2電子制御装置は、要求信号を受信すると、その要求信号が受信されない継続時間がタイムアウト時間に達したと判定するまで制御対象を通電駆動する、ネットワークシステムにて、制御対象の動作の応答性を悪化させずに消費電力を低減する。【解決手段】第1電子制御装置は、制御対象の動作条件が成立していると判定している場合に、第2電子制御装置へ上記要求信号を送信する。また、第1電子制御装置は、動作条件が成立する可能性の高さを判定可能な制御情報を第2電子制御装置に送信する。第2電子制御装置は、要求信号を受信すると、その後、要求信号が受信されない継続時間がタイムアウト時間に達したと判定するまで制御対象を通電駆動し続ける。更に第2電子制御装置は、第1電子制御装置からの制御情報に基づきタイムアウト時間を変更する(S420〜S440)。【選択図】図5
