    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 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.

    Abstract: A brake system may include an actuation device that may actuate a first piston-cylinder unit to apply pressure medium to at least one brake circuit via a valve device, where a piston of the first piston-cylinder unit separate first and second working chambers; a second piston-cylinder unit, having an electromotive drive and a transmission to feed pressure medium to at least one of the brake circuits via a valve device; and a motor-pump unit having a valve device to feed pressure medium to the brake circuits. The motor of the electromotive drive of the second piston-cylinder unit and the motor of the motor-pump unit may be used jointly or independently of one another, under control of a control device. The motor-pump unit is connected via two hydraulic connections, one or both of which may incorporate separating valves, to the first and second working chambers of the first piston-cylinder unit.

    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 diagnostic method, in particular to determine the leak tightness of at least one seal and/or one valve, for at least one component of a vehicle, wherein a piston cylinder unit, whose piston is driven by an electromotive drive, forms a pressure supply unit, wherein a control unit identifies the piston position and/or piston movement of the piston by means of at least one sensor and the pressure generated by the pressure supply unit or the motor current flowing through the drive by means of at least one sensor. During the diagnostic method, the control unit may be used to measure quantities relating to piston movement/position, pressure, and/or pressure variation.
