Abstract
The vehicle-use electronic control device includes a main microcomputer and a sub microcomputer. The sub-microcomputer is configured to be in one of a normal operation mode, a sleep mode and a stop mode, and to learn a frequent use time period in which frequency of use of the vehicle is high. The sub-microcomputer continues to be in the sleep mode if the frequent use time period prevails, and changes from the sleep mode to the stop mode if the frequent use time period does not prevail in order to further reduce the dark current.
