    Abstract: A brake system includes two brake circuits having brake circuit lines for two vehicle axles and at least one hydraulic wheel brake in each brake circuit. Each wheel brake is connectable to a corresponding brake circuit or brake circuit line via a paired switch valve for pressure build-up and release in the wheel brake using a pressure supply device that can build up pressure in both brake circuits. At least one circuit separating valve blocks or releases a hydraulic connection line connecting the two brake circuits. At least one outlet valve connects an accumulator container to at least one brake circuit to release pressure. A master cylinder having only one working chamber is actuable by a brake pedal. The working chamber is connectable to the brake circuit line of a brake circuit. A switch valve is used to close or release the hydraulic line.

    Abstract: A brake system for a vehicle may include at least two hydraulic brake circuits, each having at least one hydraulically acting wheel brake, at least two pressure supply devices, each of which is driven by an electromotive drive, at least one valve assembly having valves for the wheel-individual adjustment of brake pressures and/or for separating the wheel brakes from, or connecting same to, a pressure supply device, at least one electronic control and regulating unit, one of which is a superordinate central control unit that controls individual control and regulating units of the components of the brake system, as well as at least one additional electric drive motor for at least one axle or wheel of the vehicle. The brake system may use the at least one pressure supply device and/or the at least one electric drive motor for controlling pressure in at least one wheel brake for steering interventions.

    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: 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.
