Claim 11:
12. 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 for braking the vehicle based on a stroke to the braking pedal;
determining whether to drive a regenerative braking unit provided in the vehicle;
calculating, when the regenerative braking unit is driven, a regenerative braking force required for performing regenerative braking of the vehicle based on the total required braking force;
determining whether the total required braking force is provided by the regenerative braking force alone when the regenerative braking unit is driven;
starting a first regenerative braking mode upon determining that the total required braking force is provided by the regenerative braking force alone; and
when starting the first regenerative braking mode, controlling an electric booster unit to cause an increase rate of a first pedal feel force (FRD) of a reaction disk to be a first rate and to cause an increase rate of a second pedal feel force (Fspring) of a pedal spring to be a second rate greater than the first rate.
