Abstract

In view of the foregoing issues, an object of the present invention is to provide a vehicle control device that reduces the constraints of heat generation and charging time of a booster circuit, and decreases favorably the fuel consumption and exhaust emission of an engine. A vehicle control device installed in a vehicle, the device includes: a battery; a high-voltage battery that has a voltage higher than a voltage of the battery; and a fuel injection device that injects fuel into an internal combustion engine, wherein the vehicle control device includes a control unit that determines whether to supply a drive current to the fuel injection device by the battery or supply a drive current to the fuel injection device by the high-voltage battery, and controls the fuel injection device.
