Abstract

A method for operating an electrically controllable brake system for a motor vehicle having at least one electrically actuated valve arrangement for setting a pressure difference between a second brake pressure and a first brake pressure, wherein in a first time interval a predetermined first pressure difference is set and an associated first power consumption value of the pump is identified; in a second time interval a predetermined second pressure difference is set and an associated second power consumption value of the pump is identified; a correction value is obtained from the first power consumption value and the second power consumption value; the correction value is taken into account for setting a set-point value for the pressure difference.
