Abstract

A control device includes an engine, a starter motor configured to perform engine start, a direct-current-to-direct-current converter, a battery coupled to the starter motor with the direct-current-to-direct-current interposed therebetween, and a controller. The controller is configured to execute control of switching between first and second traveling modes. The direct-current-to-direct-current converter is configured to supply an electric power of the battery to the starter motor, and to lower an output voltage to be supplied thereto. The controller is configured to execute output limit control of lowering the output voltage to lower the output current, in a case where an output current of the direct-current-to-direct-current converter becomes equal to or higher than a threshold. The controller is configured to initiate boost permitting control when initiating the engine start in association with switching from the second to first traveling mode. The boost permitting control makes the threshold higher than a usual threshold.
