Claim 14:
15. A method of controlling a brake system, the method comprising:
calculating, in response to a depression on a braking pedal of a vehicle as measured by a pedal travel sensor, a total required braking force (Ftotal) for braking the vehicle based on a stroke to the braking pedal;
calculating, when a regenerative braking unit provided in the vehicle is driven, a regenerative braking force (Freg) required for performing regenerative braking of the vehicle based on the total required braking force (Ftotal);
calculating, based on the regenerative braking force (Freg), a first displacement (d1) of a motor piston configured to depress a reaction disk to provide a driver with a pedal feel;
determining whether the total required braking force (Ftotal) is provided by the regenerative braking force (Freg) alone when the regenerative braking unit is driven;
starting a first regenerative braking mode upon determining that the total required braking force (Ftotal) is provided by the regenerative braking force (Freg) alone; and
controlling an electric booster unit provided in the vehicle to cause the motor piston to have a displacement that is equal to the first displacement (d1).
