A brake negative pressure control device for a vehicle includes an ECU. The ECU is configured to (i) control a first fuel injection valve and a second fuel injection valve, when the ECU determines that a negative pressure in a negative pressure chamber is insufficient, such that a ratio of a fuel injection amount by the first fuel injection valve is decreased and a ratio of a fuel injection amount by the second fuel injection valve is increased; and (ii) control an opening degree of the throttle valve, when the ECU determines that the negative pressure in the negative pressure chamber is insufficient, such that the opening degree of the throttle valve at the time when the ECU determines that the negative pressure is insufficient is smaller than an opening degree of the throttle valve at the time when the ECU determines that the negative pressure is not insufficient.
