Abstract
An electronic control apparatus is used for a power supply system that includes a rotating electric machine, a power generation control unit, first and second storage batteries, first and second switches, and a host control unit. The electronic control apparatus determines whether a predetermined process completion condition is met, without communicating with the host control unit, after an ignition switch of a vehicle is switched from an on state to an off state. The process completion condition indicates that a predetermined switch-off process is completed. The switch-off process is performed by the power generation control unit after the ignition switch is switched from the on state to the off state. The electronic control apparatus maintains the first switch in on state until determined that the process completion condition is met after the ignition switch is switched from the on state to the off state.
