Hydraulic Braking System for a Vehicle and Corresponding Operating Method

A hydraulic braking system for a vehicle includes a master brake cylinder, a hydraulic unit and a plurality of wheel brakes, the hydraulic unit including at least one brake circuit for brake pressure modulation in the wheel brakes. A bistable solenoid valve is associated with at least one wheel brake, which valve is looped into the corresponding fluid channel, immediately upstream of the associated wheel brake, and in a de-energized open position enables brake pressure modulation in the associated wheel brake, and in a de-energized closed position seals a current brake pressure in the associated wheel brake, wherein a hydraulic force brought about by the sealed-in brake pressure acts in a seat-opening manner in the corresponding bistable solenoid valve.
