Abstract
An electronic control unit includes a microcomputer and a monitoring section. The monitoring section monitors an operation of the microcomputer and outputs a reset signal to the microcomputer when determining that an abnormality occurs in the microcomputer. The microcomputer includes an acquisition section, a determination section, and a time calculation section. The acquisition section acquires time information from outside the microcomputer. When the microcomputer starts up, the determination section determines whether the microcomputer stopped the operation due to unknown cause. When the determination section determines that the microcomputer stopped the operation due to unknown cause, the time calculation section calculates stop time information based on the time information acquired by the acquisition section before the microcomputer stopped the operation and the time information acquired by the acquisition section after the microcomputer starts up, and stores the stop time information in a time storage portion.
