Summary:To appropriately reduce the time required for re-writing processing in resuming re-writing of a program after its interruption.SOLUTION: An electronic control device 19 comprises: a first processing flag setting unit 106a that performs first processing that is part of processing concerning with re-writing of a program to set a first processing flag indicating the processing state of the first processing; a second processing flag setting unit 106b that, after the first processing that is part of the processing concerning with the re-writing of the program is performed, by a program re-writing unit performing second processing that is another part of the processing concerning with re-writing of the program, sets a second processing flag indicating the processing state of the second processing; and a retry point specification unit 106c that, when part of the processing concerning with the re-writing of the program is interrupted, specifies a retry point in resuming the re-writing of the program on the basis of the first processing flag and the second processing flag.SELECTED DRAWING: Figure 170 【課題】プログラムの書換えを中断して再開する場合において、書換え処理に要する時間を適切に低減する。【解決手段】電子制御装置19は、プログラムの書換えに関与する処理の一部である第1処理を行うことで、その第1処理の処理状況を示す第1処理フラグを設定する第1処理フラグ設定部106aと、プログラムの書換えに関与する処理の一部である第1処理を行った後に、前記プログラム書換え部がプログラムの書換えに関与する処理の別の一部である第2処理を行うことで、その第2処理の処理状況を示す第2処理フラグを設定する第2処理フラグ設定部106bと、プログラムの書換えに関与する処理の一部が中断された場合において、プログラムの書換えを再開する際のリトライポイントを第1処理フラグ及び第2処理フラグに基づいて特定するリトライポイント特定部106cと、を備える。【選択図】図170
