Abstract
A vehicle control apparatus includes a controller that switches a vehicle between an HEV traveling mode and an EV traveling mode. When the output current of a DC-to-DC converter becomes equal to or higher than a threshold, the controller decreases the output current by decreasing the output voltage of the DC-to-DC converter through output regulation control. The controller makes switching between a normal setting in which the threshold for the output regulation control is set to a reference threshold and a boost setting in which the threshold is set to a boost threshold higher than the reference threshold. The controller prohibits the boost setting when a power margin for boosting becomes equal to or lower than a first power margin value in the HEV traveling mode and when the power margin for the boosting becomes equal to or lower than a second power margin value in the EV traveling mode.
