Claim 0:
1. A system for predicting a negative pressure of a brake booster of a vehicle, comprising:
a driving information detector configured to detect driving information according to driving of the vehicle; and
a controller configured to calculate a negative pressure of an intake manifold based on a pressure of the intake manifold and an atmospheric pressure that is the driving information, the controller including a booster negative pressure predictor configured to predict the negative pressure of the brake booster by integrating over time a change rate according to a charging rate and a discharging rate of the negative pressure of the brake booster calculated using a previous negative pressure of the brake booster, which is calculated in a previous cycle according to a logic for predicting the negative pressure of the brake booster, and the negative pressure of the intake manifold and a brake pedal force of a current cycle,
wherein the controller is further configured to control the vehicle according to a result of predict the negative pressure of the brake booster.
