Abstract

The method and apparatus (130) control a drive unit (30) with an internal combustion engine (35), so that changes of an output variable of the drive unit (3) during load change are limited. The method includes formulating a desired behavior of the output variable for the load change; changing the desired behavior of the output variable by changing an air supply of the internal combustion engine and forming at least a first preliminary value for adjusting the output variable by filtering the desired behavior according to an inertia of an air system for the air supply of the internal combustion engine.
