Abstract:
A brake system in a vehicle, the vehicle including at least one wheel associated with a wheel brake cylinder, comprising:a first arrangement adjusting at least one of a pressure buildup state, a pressure holding state and a pressure reduction state of the wheel brake cylinder;at least one brake circuit coupled to the wheel brake cylinder via the first arrangement, the at least one wheel being assigned to the at least one brake circuit, the at least one brake circuit including at least one second arrangement which has at least one pump, the at least one pump providing the pressure buildup state in the wheel brake cylinder of one of the at least one wheel independent of a driver action,a third arrangement determining a specific quantity which represents a pressure of the at least one brake circuit; anda fourth arrangement detecting a delivery performance of the at least one pump during the pressure buildup state independent of the driver action,wherein the third arrangement determines the specific quantity as a function of the detected delivery performance during the pressure buildup state independent of the driver action.
