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.

Abstract: A brake system for a vehicle has at least two hydraulic brake circuits, each with at least one hydraulically acting wheel brake, and a switching valve on each hydraulically acting wheel brake, which switching valve connects in each case one hydraulically acting wheel brake to one of the two brake circuits. The brake system also has a central outlet switching valve which brings about a switchable hydraulic connection between at least one of the brake circuits and a reservoir vessel, wherein the reduction in pressure in the at least one hydraulically acting wheel brake is effected by opening the central outlet switching valve and the associated switching valve.

Abstract: A brake system for a vehicle has at least one pressure supply device which is connected to a brake circuit via a hydraulic line. Furthermore, the brake system has a hydraulic connection between at least one of the brake circuits and an accumulator container, said connection being switchable via at least one outlet switch valve, and the pressure supply device has a double stroke piston with a working stroke and a return stroke. The double stroke piston can be at least partly emptied via the outlet switch valve.

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 pressurising medium. A valve device may regulate pressure of the hydraulically actuatable device. Pressurising 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.

Abstract: An actuating device for an entirely or partially hydraulic vehicle braking system includes a master brake cylinder with a piston and a working chamber hydraulically connectable to a reservoir, a pedal feel simulator, and, via at least one normally open valve, at least one brake circuit. At least one hydraulic wheel brake is assigned to a brake circuit and connected thereto via at least one separate controllable switching valve. A pressure supply unit has a motor-driven piston and a cylinder. At least one valve assembly includes wheel-specific solenoid pressure control valves. At least one electrical control unit controls valves of the valve assembly and the motor of the pressure supply unit. Outlet valves enable discharge of hydraulic medium from wheel brakes or brake circuits into the reservoir. One housing contains the valve assembly and hydraulic component of the pressure supply unit, and a separate housing contains the master brake cylinder.
