    Abstract: A driving dynamics system for a vehicle may include a primary control unit for detecting and/or generating steering commands and braking commands; a brake system having first and second electrohydraulic pressure supply units; four hydraulically actuable wheel brakes of respective wheels; electrically actuable brake pressure adjustment valves; and an electric steering actuator for actuating at least one axle. The driving dynamics system may implement a steering command during normal operation to actuate at least one of the pressure supply units and the steering actuator and/or, to implement a braking command during normal operation, to actuate at least the second pressure supply unit and at least the brake pressure adjustment valves for a wheel-specific pressure adjustment and, in a fault case, to actuate at least the first pressure supply unit and at least the brake pressure adjustment valves for a wheel-specific pressure adjustment.

    Abstract: A brake system may include a first pressure supply unit having an electromotive drive and arranged to supply pressure medium to first and second brake circuits; a motor-pump unit to supply pressure medium to at least one of the brake circuits; a second pressure supply unit, connected to the motor-pump unit via first and second hydraulic lines and arranged to supply pressure medium to at least one of the brake circuits; and a valve unit. The second pressure supply unit may be connected via a third hydraulic line to at least one of the brake circuits. The valve unit may include at least one feed valve via which the third hydraulic line may be at least partially reversibly shut off. An isolating valve may be disposed in at least one of the hydraulic lines to at least partially reversibly shut off the at least one hydraulic line.

    Abstract: An actuation device for a hydraulically operating brake system may include: a master cylinder in a housing and having at least one piston, to which a force can be applied by, e.g., a brake pedal; pressure supply device(s), at least one of which is a piston pump or double stroke piston pump having a piston and driven by an electromotive drive, the drive moving the piston directly or via a step-up gear; at least one valve assembly with magnetic valves; and at least one electronic control and regulating unit. The brake system has at least two hydraulic circuits, and a pressure change can be carried out in at least one wheel brake via the pressure supply device(s). A first housing or module, hydraulically connected to the housing, may contain the valve assembly and the at least one piston and pressure chamber of at least one of the pressure supply devices.

    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 contain redundant components that permit braking force to be applied in case of partial or complete failure of a primary braking mechanism. The system may include at least one hydraulic brake circuit having at least one hydraulically operating wheel brake; a pressure supply device driven by an electric-motor drive; at least one electronic control and regulating device; a valve assembly having valves for setting wheel-specific brake pressures and/or for (dis)connecting the wheel brakes (from)to the pressure supply device; a piston-cylinder unit actuable by an actuating device, which can be connected to the at least one hydraulic brake circuit, to at least one brake unit comprising an electric drive motor, to an electric parking brake, to a hydraulically supported electromechanical brake, and/or to an electromechanical brake; at least one electric drive motor for at least one axle or wheel; and a central control unit.

    Abstract: A pressure generating device may comprise a piston-cylinder unit having a bilaterally acting piston with two effective surfaces defining two respective, separate working spaces in a sealing manner. Each working space is connected via a hydraulic line to a hydraulic circuit, wherein at least one hydraulic chamber of a consumer is connected to each hydraulic circuit, and wherein a drive drives the piston. Each working space may be in communication with a reservoir for hydraulic medium, via a respective hydraulic line having a respective switching valve. Alternatively, one or both working spaces may be in communication with a reservoir for hydraulic medium via a hydraulic line, with a switching valve in one or both hydraulic lines, and/or a respective outlet valve may be associated with one or more hydraulic chambers of the consumer, and a further connecting line having a switching valve may connect the pressure chambers and/or hydraulic lines.
