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.

A device for a hydraulic actuating system, including:
- a main module, arranged in one housing, comprising:
- at least one pressure supply device, which is driven by an electromotive drive, and which is in the form of a pump having a single-stroke or double-stroke piston for varying pressure in at least one hydraulic circuit, wherein the electromotive drive is arranged to adjust the single-stroke or double-stroke piston of the pump via a transmission mechanism, and
- a valve arrangement with at least one solenoid valve which serves for individually setting hydraulic pressures in the at least one hydraulic circuit and/or for separating and connecting the at least one hydraulic circuit from and to the pressure supply device and/or a piston-cylinder unit of the at least one pressure supply device;
- hydraulic ports for at least two hydraulic consumers of the hydraulic actuating system;
- an electrical control unit (ECU) with motor control electronics for a brushless direct current (BLDC) motor, valve output stages and sensors, for activating the at least one solenoid valve and the electromotive drive in order to set a pressure in the hydraulic actuation system by adjustment, and
- a superordinate control device,
- wherein the main module is either electrically connected or electrically and hydraulically connected to at least one further system component or actuating unit,
- wherein the superordinate control device and the electrical control unit are electrically connected,
- wherein the superordinate control device is further electrically connected to at least one traction motor, and
- wherein the superordinate control device is configured to control a brake function of the at least one traction motor and to control one or more of the following functions of the device:
- brake force boosting, blending, anti-lock braking (ABS), electronic stability control (ESP), emergency braking, or distance control.
