PROBLEM TO BE SOLVED: To provide an automobile electronic control device capable of performing initialization in an equivalent time period with a normal condition regardless of the number of faulty cores.SOLUTION: A core 1110 transmits question data to a core 1120. On the basis of the received question data, answer data is calculated with a predetermined calculation formula, and it is returned to the core 1110. The core 1110 receives the answer data from the core 1120. The core 1110 uses correct answer data preliminarily embedded in a program, and is compared with the data returned from the core 1120. When the data calculated by the core 1120 and the correct answer data match, it is determined to be normal and the core 1120 performs normal control. If the answer data calculated by the core 1120 and the correct answer data do not match, the core 1120 is stopped. In the logic, the diagnosis of the core 1120 is conducted by replacing the core 1110 with the core 1120.SELECTED DRAWING: Figure 5

    【課題】故障しているコアの数によらずに、初期化を正常時と同等の時間で実施することが可能な自動車用電子制御装置を提供する。【解決手段】コア1110がコア1120に問題データを送信する。受信した問題データを元に、予め決められた計算式で回答データを算出し、コア1110に返信する。コア1110はコア1120から回答データを受信する。コア1110は予めプログラムに埋め込まれた正解データを用い、コア1120から返信されたデータと照合する。コア1120の算出したデータと正解データが一致すれば正常と判断しコア1120は通常制御行う。一方コア1120の算出した回答データと正解データが一致しない場合はコア1120を停止する。前記ロジックにおいて、コア1110とコア1120を入れ替えることで、コア1120の診断を行う。【選択図】図5
