Abstract
Two brake circuits ( ) each comprise at least one wheel brake (VL, VR, HL, HR), a fluid control module ( ) for fluid pressure control at the at least one wheel brake, and at least one brake line ( ) for connecting the fluid control module to the at least one wheel brake, such that only one brake line is connected to each wheel brake. In order to increase the safety of the vehicle brake system during braking with only one intact brake circuit, according to the invention in the vehicle brake system a sensor arrangement ( ) for determining failure of a brake circuit is provided, and the fluid control modules in the event of failure of a brake circuit are capable of controlling the fluid pressure at the at least one wheel brake of the intact brake circuit in such a way that the gradient of a developing yawing moment (G) of a vehicle provided with the vehicle brake system does not exceed a predetermined maximum value.
