Abstract
A power-operated hydraulic brake system for a wheeled vehicle includes a main brake line; a brake valve configured to input a target brake pressure into the main brake line, the brake vale configured to be actuated via a brake pedal; a plurality of wheel brake lines branching off from the brake valve, each of which leads to an actuating unit of a wheel brake; and a valve assembly of an ABS control system. The valve assembly includes an inlet valve arranged between the main brake line and one of the wheel brake lines, and an outlet valve arranged between the relevant wheel brake line and an unpressurized return line. The inlet valve and the outlet valve are pressure-controlled 2/2-way switching valves with correspondingly large switching cross sections, and the inlet valve and the outlet valve are each assigned at least one pilot valve designed as a solenoid switching valve.
