Abstract: A multiple-circuit, hydraulically open brake has two single-circuit pressure generators hydraulically connected in parallel between at least one fluid container and at least two wheel brakes and a modulation unit for individual brake pressure modulation in the at least two wheel brakes. A first pressure generator is assigned to a main system which has a first energy supply and a first evaluation and control unit, and a second single-circuit pressure generator is assigned to a secondary system, which has a second energy supply which is independent of the first energy supply, and a second evaluation and control unit. The second evaluation and control unit controls the second pressure generator. Components of the modulation unit are assigned to the main system so that the modulation unit and the first pressure generator are controlled by the first evaluation and control unit and supplied with energy by the first energy supply.

Abstract: An electronically slip-controllable power-assisted braking system for a motor vehicle. The power-assisted braking system is equipped with a hydraulically acting booster device that is inserted in a brake circuit downstream from an actuation device and has a piston unit movably guided in a cylinder housing. The piston unit is embodied in stepped fashion and divides an interior space of the cylinder housing into multiple booster chambers impinged upon by pressure medium. At least one of these booster chambers is capable of being impinged upon by pump pressure from a pump driven by external force.

Abstract: A hydraulic braking system for a motor vehicle, including at least two brake circuits which each include at least one hydraulically actuatable wheel brake and at least one electrically operable pressure generator, the pressure generators being activatable as a function of a brake request of the motor vehicle or a driver of the motor vehicle. A respective electric actuator is assigned to each pressure generator for its operation, and at least one activatable emergency operation valve is interconnected between the brake circuits, which in a first switching position disconnects the brake circuits from one another and in a second switching position connects them to one another.

Abstract: An operational method for controlling a first brake pressure generator. The operational method includes reading the detected wheel speeds into the brake pressure generator control unit, simulating a control strategy of the secondary control unit for controlling the hydraulic unit based on the wheel speeds so that a brake pressure required at the respective wheel is ascertained, predicting the pressure resulting from the control strategy of the secondary control unit and the brake pressure at the first brake pressure generator, and controlling the first brake pressure generator in accordance with the predicted resulting pressure if the predicted resulting pressure exceeds a limit value, so that the pressure resulting at the brake pressure generator is lower than the predicted pressure due to an activation of the first brake pressure generator.
