Abstract

A method for regulating a pressure setting in a braking system includes receiving a pressure demand and determining a pressure demand gradient from the pressure demand, determining a volume flow requirement from the pressure demand gradient, generating a hydraulic pressure by utilizing a pressure application device, determining an actual volume flow of the pressure application device, regulating an overflow valve on the basis of the pressure demand and the difference between the actual volume flow and the volume flow requirement. A special mode is activated when the pressure demand gradient exceeds a gradient limit value, a minimum value for the volume flow requirement being set in the special mode on the basis of a last maximum of the volume flow requirement. The special mode is deactivated when a difference between the pressure demand and a system pressure falls below a first limit value.
