Abstract
A traction-slip controlled vehicle brake system having a) a service-brake valve, which generates an actuation-dependent pressure at an outlet port; b) a valve device, in a first operating position, establishes a connection from a pressure medium reserve and, in a second operating position, from a 2/2 solenoid valve to a brake actuator; c) the solenoid valve being connected to the outlet port of the service-brake valve and to a first connection of the valve device. The solenoid valve and valve device are controllable by a control device to d) allow the solenoid valve to switch open and the valve device to switch to the first operating position for traction-slip control; e) and a brake pressure generated at a predetermined level based on the pressure medium from the pressure medium supply in the brake actuator; the solenoid valve being switched closed and the valve device to the first operating position.
