To provide an automobile electronic controller comprising a first arithmetic processing unit and a second arithmetic processing unit outputting a reset request signal to the first arithmetic processing unit when abnormality occurs in the operation of the first arithmetic processing unit so that rewriting of a program can be suppressed from becoming impossible.SOLUTION: An automobile electronic controller includes a second arithmetic processing unit (sub-microcomputer) that when an own program is rewritten (S602), determines the matching between identification information IDm of a program of a first arithmetic processing unit (main microcomputer) and identification information IDs of a program of the second arithmetic processing unit (S603) and, when the identification information ID is in mismatch, stops a monitoring function of the first arithmetic processing unit (S605) and sets the first arithmetic processing unit in a program rewritable mode (S606).SELECTED DRAWING: Figure 3

    【課題】第1演算処理装置と、第1演算処理装置の動作に異常が生じたときに第1演算処理装置にリセット要求信号を出力する第2演算処理装置とを備える自動車用電子制御装置において、プログラムの書き換えが不能になることを抑止する。【解決手段】第2演算処理装置(サブマイコン)は、自プログラムの書き換えが行われたときにS602、第1演算処理装置(メインマイコン)のプログラムの識別情報IDmと第2演算処理装置のプログラムの識別情報IDsとの整合性を判断しS603、識別情報IDが不整合であるときに第1演算処理装置の監視機能を停止してS605、第1演算処理装置をプログラムの書き換えが可能なモードに設定するS606。【選択図】図3
