Patent ID: 8215722

Claim:
A method for operating an electrically controllable hydraulic valve, such as an analog/digital inlet valve ( 10 ) of a friction brake in a motor vehicle brake system, the method comprising: determining an actuation current for a hydraulic valve by linking an available opening current characteristic curve (I open (ΔP) table ) of the hydraulic valve to a correction value (i grad ), wherein the correction value (i grad ) is predetermined depending on a quotient of the product of the requested pressure gradient and the flow resistance (R H ) of the hydraulic circuit associated with the hydraulic valve ( 10 ), and the product of the pressure difference (ΔP) at the hydraulic valve ( 10 ) and the hydraulic capacity (C Wheel ) of the wheel circuit associated with the hydraulic valve ( 10 ); and applying the actuation current to the hydraulic valve ( 10 ).
