  • Patent number: 10899330
    Abstract: A hydraulic vehicle brake system having at least one brake pedal, a pedal-travel simulator, at least one hydraulically operable wheel-brake unit and a switching valve between the brake pedal and the pedal-travel simulator. The switching valve is adjustable between a first switching position, in which the brake pedal is connected to the pedal-travel simulator and decoupled from the wheel-brake unit, and a second switching position, in which the brake pedal is decoupled from the pedal-travel simulator and the brake pedal is connected to the wheel-brake unit. In the first switching position, a pressure-supply unit is connected at the same time to the wheel-brake unit.
