Abstract
A braking pressure control device for a hydraulic two-circuit brake system with a pneumatic braking force amplifier and an antilock brake system (ABS) that operates on the feedback principle, in which a switching valve is provided for each brake circuit. Each switching valve is switchable from a position connecting the brake circuit with a pressure outlet of the braking device into a position that shuts off this pressure outlet from the brake circuit. The control device has a precharging control valve that is switchable from a position that shuts off this pressure outlet from the low-pressure inlet of the feedback pump into a position that connects the pressure outlet with the feedback pump, as well as an electronic control unit that processes the sensor signals that contain at least the information on the type of actuation of the brake pedal to generate the signals required for automatic full brake application for controlling the switching valves, the precharging control valves, the feedback pumps, the inlet and outlet valves of the ABS, as well as a control valve by which the drive chamber of the braking force amplifier can be vented.
