Abstract: A brake system may include an actuation device, in particular a brake pedal; a first piston-cylinder unit with two pistons, in particular an auxiliary piston and a second piston, in order to supply brake circuits with a pressure medium via a valve device, wherein one of the pistons, in particular the auxiliary piston, can be actuated by means of the actuation device; a second piston-cylinder unit comprising an electric motor-powered drive, a transmission, and at least one piston in order to supply pressure medium to at least one of the brake circuits via a valve device; and a motor pump unit with a valve device in order to supply pressure medium to the brake circuits. The brake system may further include a hydraulic travel simulator which is connected to a pressure or working chamber of the first piston-cylinder unit.

Abstract: An actuation system for at least one hydraulically actuatable device, e.g., a vehicle brake, may include an actuation device, e.g., a brake pedal, at least one first pressure source that can be actuated using the actuation device, and a second pressure source having a pressure-generating arrangement that is moveable in two directions, and which includes an electro-mechanical drive for the pressure-generating arrangement. Each pressure source is connected via at least one hydraulic line to the hydraulically actuatable device for supplying pressurizing medium. A valve device may regulate pressure of the hydraulically actuatable device. Pressurizing medium can be supplied in a controlled manner in both movement directions of the pressure-generating arrangement. Provision is made for two working chambers of the second pressure source to be connected by a hydraulic line, and a valve device may be arranged in the hydraulic line.

The vehicle axle may include at least one pressure supply device, driven by an electric-motor drive, to control pressure in the wheel brakes; at least one control and regulating device; a valve assembly having values for setting wheel-specific brake pressures and/or for disconnecting/connecting the wheel brakes from/to the pressure supply device, and at least one electric drive motor for driving and braking a vehicle wheel or the axle. At least one pressure supply device is used to control the pressure of and/or provide pressure to at least one additional brake unit in the form of an electric parking brake, a hydraulically supported electromechanical brake, an electromechanical brake and/or a force-supporting steering device, a gear actuator and/or transmission actuator, and/or a torque vectoring module.

Abstract: A braking system for a vehicle may include a hydraulic brake pedal system having a master cylinder having at least one pressure chamber, from which a hydraulic output is coupled to at least one brake circuit via an infeed switch valve. The master cylinder is coupled to a reservoir via at least one opening via a hydraulic connection. A failure of a pressure chamber seal of the at least one pressure chamber of the master cylinder is safeguarded by at least one redundancy, and the failure of the pressure chamber seal or the redundancy of the pressure chamber seal of the at least one pressure chamber of the master cylinder can be diagnosed.

Abstract: A brake system for a motor vehicle may include at least one pressure supply device, formed by a hydraulic piston-cylinder unit driven by an electric motor, for hydraulic adjustment of a brake piston of at least one wheel brake, and at least one electromechanically actuatable wheel brake for electrical adjustment of a brake piston of a wheel brake. An electric motor and a first gearbox, which transmits the driving force of the electric motor to a further gearbox, are provided for electromechanical actuation of the wheel brake. The electromechanically actuatable wheel brake has a hydraulic control device having a piston-cylinder unit, the control piston of which serves for adjusting the brake piston and/or exerting a force on the brake piston. The control piston can be adjusted or a force can be exerted on the control piston.

Abstract: A brake system and a method for controlling a brake system. The brake system may include a first module having a first pressure supply unit with an electromotive drive, an optional second pressure supply unit and a first control device for controlling the first pressure supply unit; a second module having a third pressure supply unit, isolation valves and brake-pressure-adjusting valves, and a second control device for controlling the brake-pressure-adjusting valves; and a detection unit for detecting a first case of error. The brake system is designed such that, in the first case of error, in order to provide an ABS function and/or a yaw torque intervention, it implements a (wheel-specific and/or selective) adjustment of the pressures in the wheel brakes by actuating at least one of the brake-pressure-adjusting valves of the second module and/or the isolation valves of the second module and the first pressure supply unit.
