Method for controlling an electronically slip-controllable power braking system

A method for controlling an electronically slip-controllable power braking system of a motor vehicle. Power braking systems are equipped with a plunger unit, which includes a plunger piston accommodated in a plunger cylinder and delimiting a working chamber, for generating brake pressure in brake circuits. This plunger piston is actuatable by an electronically activatable drive in a pressure buildup direction or in the opposing spatial direction thereto in a pressure reducing direction. A time-limited drive of the plunger piston takes place in the pressure reducing direction as soon as an actual brake pressure generated by the plunger unit has reached a predefinable setpoint brake pressure and a decoupling of a wheel brake and the plunger unit from an associated brake circuit has taken place.
