Claim 18:
19. The method of claim 16, comprising:
forming a first pedal feel force (FRD) with a reaction disk when depressed by one or more of an operating rod of the master cylinder and the motor piston; and
forming a second pedal feel force (Fspring) with a pedal spring having one end connected to the operating rod and another end supported by the electric booster unit that is dependent on a distance between the operating rod and the electric booster unit,
wherein, when in the first regenerative braking mode, the method is configured to be responsive to the pedal stroke increasing for controlling the electric booster unit to increase the first pedal feel force (FRD) at a first rate and to increase the second pedal feel force (Fspring) at a second rate greater than the first rate.
