PROBLEM TO BE SOLVED: To provide a vehicular electronic control device capable of suppressing a non-monitoring state of a microcomputer.SOLUTION: An ECU 100 includes a first microcomputer 10 and a second microcomputer 20. The first microcomputer 10 is mounted with a normal task 11 which is executed by ON of an IG switch and is finished with the execution by OFF of the IG switch. A second microcomputer 20 is mounted with a BATT task 21 which is executed by a BATT system start-up factor generated before the ON of the IG switch and is finished with the execution by the stop of the BATT system start-up factor after the OFF of the IG switch. The first microcomputer 10 is mounted with a special task 12 including second WDC monitoring processing 12c for monitoring the operation of the second microcomputer 20 according to the generation of the BATT system start-up factor in addition to the normal task 11.

    【課題】マイコンの無監視状態を抑制できる車両用電子制御装置を提供すること。【解決手段】ECU100は、第1マイコン10と第2マイコン20とが設けられている。また、第1マイコン10は、IGスイッチのオンで実行され、IGスイッチのオフで実行が終了される通常タスク11が搭載されている。一方、第2マイコン20は、IGスイッチのオンよりも先に発生するBATT系起動要因で実行され、IGスイッチのオフよりも後にBATT系起動要因が停止することで実行が終了されるBATTタスク21が搭載されている。そして、第1マイコン10は、通常タスク11に加えて、BATT系起動要因の発生に応じて第2マイコン20の動作を監視する第2WDC監視処理12cを含む特殊タスク12が搭載されている。【選択図】図1
