Abstract
A control device for an electrified vehicle includes a travel ECU that controls the travel of the electrified vehicle, and an auxiliary ECU that controls the voltage of an auxiliary battery separately from the travel ECU. The auxiliary ECU receives battery information indicating the state of the auxiliary battery from the travel ECU, generates a voltage request signal that requests voltage from the DC-DC converter based on the battery information, and sends the voltage request signal to the travel ECU. When the travel ECU receives the voltage request signal from the auxiliary ECU, it outputs a control signal corresponding to the voltage request signal to the DC-DC converter.
