To execute program writing processing onto a non-volatile memory of an automobile electronic controller at high speed.SOLUTION: An automobile electronic controller (ECU) 100 acquires division data that is set in a size according to a time-out time from an external writing device 300 via communication, and after a start of writing processing of the acquired division data onto a ROM 120, if the writing processing is not completed before the time-out time elapses, sends a requirement of postponement of resend of a program to the writing device 300, thereby enabling continuation of the writing processing of the division data onto the ROM 120 at least until the time-out time elapses again.SELECTED DRAWING: Figure 2

    【課題】自動車用電子制御装置における不揮発性メモリへのプログラムの書込み処理を高速に実行する。【解決手段】自動車用電子制御装置(ECU)100は、タイムアウト時間に応じてサイズ設定した分割データを外部の書込み装置300から通信によって取得し、該取得した分割データのROM120への書込み処理を開始してからタイムアウト時間が経過する前までに当該書込み処理が完了しない場合に、プログラムの再送を延期する延期要求を書込み装置300に送信して、少なくともタイムアウト時間が再度経過するまでROM120への分割データの書込みを継続可能にする。【選択図】図2
