To improve the precision of a rewriting work of a control program for a vehicular electronic control device.SOLUTION: A processor of a vehicular electronic control device that includes a memory enabling electrical rewriting of data, and the processor reads, when receiving a request which is for rewriting of a control program and which contains object information representing the vehicular electronic control device having the program subjected to rewriting, the identification information of the vehicular electronic control device stored in the memory, and the object information from the rewriting request. Next, the processor checks up the identification information with the object information, and determines whether or not to execute the rewriting of the control program on the basis of the check-up result.SELECTED DRAWING: Figure 2

    【課題】車両用電子制御装置の制御プログラムの書き換え作業の精度を向上させる。【解決手段】電気的にデータを書き換え可能なメモリと、プロセッサとを含んで構成された車両用電子制御装置のプロセッサが、プログラムの書き換え対象とする車両用電子制御装置を示す対象情報を含んだ、制御プログラムへの書き換え要求を受信したときに、前記メモリに格納された前記車両用電子制御装置の識別情報を読み出すとともに前記書き換え要求から前記対象情報を読み出す。そして、前記識別情報と前記対象情報とを照合し、当該照合結果に基づいて前記制御プログラムの書き換えを実行するか否かを決定する。【選択図】図2
