Abstract

A method for ascertaining a setpoint value for a manipulated variable for the actuation of a low-pressure pump in a fuel-supply system for an internal combustion engine having a high-pressure accumulator and a high-pressure pump, the high-pressure pump being operated in a full delivery mode, and the low-pressure pump being actuated so that a pressure provided by the low-pressure pump is reduced, and the setpoint value at which a dip in a delivery quantity of the high-pressure pump is detected is ascertained while taking into account an actuation value of the manipulated variable.
