  • Electric vehicle control device
    Patent number: 9216651
    Abstract: An electric vehicle control device includes a first microcomputer and a second microcomputer and a reset process device. The first and second microcomputers share a power source, have separate control functions, and allow for independent rewriting of their respective control programs. The reset process device monitors mutual microcomputer operation and performs a reset process that turns off power relays belonging to an onboard power system when a microcomputer operation error is identified. The reset process device includes a power shut-off reset process unit for performing a reset process that shuts off the flow of power through the onboard power system and turns off the power relays in this powered-off state when resetting due to a microcomputer operation error not caused by a microcomputer error being identified.
