The present invention relates to a control method for a brake booster system, which assists a braking force in case of a shortage of engine negative pressure (vacuum pressure) provided to a booster, and comprises: (S110) a booster performance map calculation step in accordance with engine negative pressure; (S120) a master cylinder pressure measuring step; (S130) a step of calculating a braking force assist area in case a normal condition output value which is calculated from the performance map is different from a master cylinder pressure value; and (S140) a step of forcibly pressurizing a wheel cylinder assembly with pressure responding to the braking force assist area through an electronic stability control device. |
