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 drive and braking system for a vehicle, comprising:
- at least one traction motor configured to be operated as a generator to brake a wheel or an axle of the vehicle;
- a main module, comprising
- a pressure supply device driven by an electromotive drive for changing pressure in at least one hydraulic circuit;
- and
- a controller for controlling the electromotive drive;
- wherein the pressure supply device and the controller are integrated into the main module;
- and
