A method for controlling a pedal lever of a hydraulic power brake for an at least partially automated mobile platform. In the method, the pedal lever acts mechanically on a master brake cylinder, and the pedal lever is mechanically coupled to an actuator. The method includes: providing a first signal to a control unit for the power brake for the purpose of controlling the pedal lever so as to move same into a passive position; establishing a first hydraulic connection between the master brake cylinder and a compensating volume; and transferring a first hydraulic volume of the master brake cylinder into the compensating volume by means of the actuator acting on the pedal lever in order to control the pedal lever so as to move same into a passive position.

A primary piston assembly for a master brake cylinder of a braking system of a vehicle, including a first primary piston component having a first piston element to which a driver braking force is transmittable in such a way that a pressure chamber volume of a pressure chamber of a master brake cylinder of the braking system which is fillable with liquid is reducible by moving the first piston element with the aid of the driver braking force, and a second primary piston component having a second piston element to which the first braking assisting force is transmittable in such a way that the pressure chamber volume of the pressure chamber is reducible by moving the second piston element with the aid of the first braking assisting force.

A brake booster coupling device includes: a braking piston, an input piston displaceable by an operation of a brake input element from its starting position by a driver braking distance, a force transmission between the input piston displaced by a driver braking distance below a predefined threshold value and the braking piston is suppressed, and a booster piston displaceable with the aid of the brake booster drive such that the braking piston, which contacts the booster piston, is displaceable with the aid of the brake booster drive from a non-braking position into a braking position; a contact element displaceable by a displacement of the braking piston from the non-braking position into the braking position such that a first contact surface of the contact element contacts a second contact surface of the input piston in such a way that a driver brake force is transmittable to the braking piston.
