Abstract

Method for optimizing the load build-up of an internal combustion engine (10), which is connected at its inlet (28) to an air supply system (30) and at its outlet (52) to an exhaust system (50), wherein the internal combustion engine (10) is assigned at least two different means (18, 34, 36, 46, 56, 76) for controlling a gas flow (92) supplied to the combustion chambers (12) of the internal combustion engine (10), wherein at least one of the means (18, 34) is an actuator (88) with a fast system response to a change in the gas flow (92) and at least one further means (36, 46, 56, 76) is an actuator (90) with a slow system response to a change in the gas flow (92), comprising the following steps: - Determining a signal for the change in torque of the internal combustion engine (10), - Transmission of an unfiltered signal to the actuator (90) with the slow system response, and - Transmission of a filtered signal to the actuator (88) with the fast system response, wherein - a driving behavior factor (FVF) is calculated from a difference between the filtered signal and the unfiltered signal, whereby the filtered signal for the actuator (88) with fast system response is converted into the signal for the actuator (90) with slow system response to the change in gas flow (92) using this driving behavior factor (FVF).
