Patent ID: 7140699

Claim:
Method for regulating a predetermined modifiable brake pressure in the wheel brakes of a brake system which includes an actuating device and at least one hydraulic valve, the method comprising: monitoring a pressure associated with the actuating device; determining a nominal pressure for the wheel brakes based on the monitored actuating device pressure; providing a characteristic curve that correlates a valve current of the hydraulic valve with a pressure difference between the nominal pressure for the wheel brakes and the monitored actuating device pressure; determining the pressure difference between the nominal pressure for the wheel brakes and the monitored actuating device pressure; and comparing the determined pressure difference to the characteristic curve and determining a correcting variable of the hydraulic valve according to the characteritstic curve wherein the nominal pressure is determined according to the function P nomnial =P point of max. boosting +factor K ×P TMC −P point of max. boosting ) with P nomnial =nominal pressure, P point of max. boosting =pressure at the point of maximum boosting of an associated brake booster and P TMC =pressure of the actuating device.
