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. |
