Hydraulic Vehicle Braking System

Abstract

A hydraulic vehicle braking system having a primary braking cylinder to which the vehicle braking system is connected via a separating valve is disclosed. The vehicle breaking system includes slip control. A pedal path simulator is a spring-loaded hydraulic accumulator, which can be connected to the primary brake cylinder via a differential pressure controlled simulator valve. The simulator valve opens when a braking pressure in the vehicle braking system is greater than a primary braking cylinder pressure; otherwise, the simulator valve is closed. If the separating valve is closed during slip control, for example, the primary braking cylinder forces braking fluid through the opened simulator valve into the hydraulic accumulator upon actuation so that a normal pedal characteristic occurs at least approximately when the separating valve is closed.
