To provide an update controller, an electronic device, an update system, and an update control method in which erroneous detection detecting an electronic device in execution of reprogramming as malfunction is prevented.SOLUTION: An update controller arranged in a control system including a plurality of electronic devices, in which malfunction detection is performed on the basis of data reception state from the other electronic devices in the starting state, and update data is distributed to target devices where data is updated among the electronic devices and data is updated by the update data, comprises a control unit. The control unit performs the data update of the target devices while power supply to the electronic devices other than the target devices is not performed, and when starting of power supply to the electronic devices other than the target devices is detected, the electronic devices other than the target devices are notified of execution of the data update for the target devices.SELECTED DRAWING: Figure 1C

    【課題】リプログラミングを実行中の電子装置を異常と誤検出してしまうのを防止する更新制御装置、電子装置、更新システム及び更新制御方法を提供する。【解決手段】更新制御装置は、起動状態にある時に他の電子装置からのデータ受信状況に基づいて異常検出を行う複数の電子装置を備えた制御システムに設けられ、複数の電子装置のうち、データの書き換え対象となる対象装置へ更新用データを配信してかかる更新用データによって上記データを書き換えさせる更新制御装置であって、制御部を備える。制御部は、対象装置以外の電子装置の電源供給が行われていない時に対象装置に対するデータの書き換えを行い、かかるデータの書き換えの実行中に、対象装置以外の電子装置への電源供給の開始を検出したならば、対象装置以外の電子装置に対し、対象装置でデータの書き換えを実行中であることを通知する。【選択図】図1C
