A method for determining a composite signal which is adjusted by controlling a drive of a pressure generator of the slip-controllable vehicle brake system accordingly. To this end, an electronic control unit records two mutually independent input quantities, converts these input quantities into evaluation signals and sums the evaluation signals mathematically to yield a composite signal. The latter represents a setpoint brake pressure that the slip-controllable vehicle brake system supplies by controlling a pressure generator accordingly.
