To appropriately control activation on the basis of an instruction from the outside.SOLUTION: An activation execution control unit of an electronic control device comprises: an operation surface information update unit that, when re-writing of a program for a second data storage surface is completed and an activation request is instructed from a master device for a vehicle, updates operation surface information indicating which of a first data storage surface and the second data storage surface an operation surface is; an execution condition determination unit that determines establishment of an execution condition for activation; and an execution control unit that, when the execution condition for activation is determined to be established by the execution condition determination unit, starts up the second data storage surface as a start-up surface on the basis of the operation surface information after a reboot. The execution condition determination unit determines, as the execution condition, at least any one of the fact that a software reset request is instructed from the master device for a vehicle, the fact that a power supply reset request is instructed from the master device for a vehicle, and the fact that a breakdown of communication with the master device for a vehicle continues for a predetermined time.SELECTED DRAWING: Figure 112 【課題】外部からの指示に基づいてアクティベートを適切に制御する。【解決手段】電子制御装置のアクティベートの実行制御部は、第２データ格納面のプログラムの書換えを完了し、且つ車両用マスタ装置からアクティベート要求が指示された場合に、第１データ格納面及び第２のデータ格納面のうち何れかが運用面であるかを示す運用面情報を更新する運用面情報更新部と、アクティベートの実行条件の成立を判定する実行条件判定部と、アクティベートの実行条件が実行条件判定部により成立したと判定された場合に、再起動後に、運用面情報に基づいて第２のデータ格納面を起動面として起動させる実行制御部と、を備える。実行条件判定部は、車両用マスタ装置からソフトウェアのリセット要求が指示されたこと、車両用マスタ装置から電源のリセット要求が指示されたこと、車両用マスタ装置との通信途絶が所定時間継続したことのうち少なくとも何れかを実行条件とする。【選択図】図１１２
