    Abstract: The invention relates to an actuating device for a motor vehicle brake, comprising the following components: an actuating device, in particular in the form of a brake pedal, a pressure supply device (11), in particular a reciprocating pump or double-acting reciprocating pump, driven by an electric motor drive (M), a piston-cylinder unit (main cylinder) (10) that can be actuated by means of the actuating device, that is connected hydraulically with a hydraulic fluid reservoir (BFR) and that forms at least two pressure chambers that are connected with hydraulic brake circuits, a valve assembly (HCU) with valves for adjusting brake pressures in a wheel-specific manner and for disconnecting or connecting the wheel brakes from or to the pressure supply device (11) and the piston-cylinder unit (10), an electronic control unit (ECU), at least one sensor device, having at least one sensor or evaluation element (3, 4, 5, 24, 24a) and a sensor target (5a, 23, 23a), preferably based on an electromagnetic principle, for sensing a movement of a device component. According to the invention,at least one sensor or evaluation element (3, 4, 5, 24, 24a) of the sensor device is arranged on or in the electronic control unit (ECU), in particular on a system printed circuit board (PCB) of the control unit (25), and that a movement of the device component (10; 45; 46; 48) is transmitted to the electronic control unit (ECU) (25) via a sensor actuating device, in particular via a mechanical actuating mechanism (17, 18, 19) or via a sensor target (5a, 23, 23a) connected with the device component and magnetic flux-conducting components (43, 43, a, 43b) based on ferromagnetic materials.

    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 device for a hydraulic actuating system, e.g., a motor vehicle brake, a clutch or a gear selector, may include the following components arranged in one housing, forming a main module: at least one pressure supply device driven by an electric motor drive, and a valve arrangement comprising at least one solenoid valve. The device may further include an electrical control unit (ECU) and valve output stages and sensors. The main module may be electrically and/or hydraulically connected to at least one further system component, which system component may include and actuating device and a travel simulator.
