Abstract:
1. An electric vehicle control device comprising: a first microcomputer and a second microcomputer that share a power source, possess separate control functions, and are programmed for independent rewriting of respective control programs; and a reset process device configured to monitor mutual microcomputer operation of the first microcomputer and the second microcomputer and to perform a reset process that turns off a power relay belonging to an onboard power system when a microcomputer operation error of at least one of the first microcomputer and the second microcomputer is identified, the reset process device comprising a power shut-off reset process unit configured to perform a reset process that shuts off the flow of power through the onboard power system and to turn off the power relay in this powered-off state when resetting due to the microcomputer operation error of at least one of the first microcomputer and the second microcomputer, not caused by a microcomputer error of the at least one of the first microcomputer and the second microcomputer, is identified.
