If a B system microcomputer is reset and reactivated while an A system microcomputer is operating normally, tasks of the A system microcomputer and tasks of the B system microcomputer can be synchronized. The B system microcomputer is reset when voltage applied to a battery decreases and falls below an operation guarantee voltage. Thereafter, when the applied voltage becomes equal to or higher than the operation guarantee voltage and the B system microcomputer is activated, the B system microcomputer outputs a request signal for requesting a synchronization signal to the A system microcomputer. The A system microcomputer outputs the synchronization signal synchronized with a periodic task. The B system microcomputer determines an execution timing of the periodic task based on the synchronization signal.
