Abstract: The invention relates to a method for operating an internal combustion engine during any driving operation and in particular during a defined testing cycle which determines compliance with regulations. The internal combustion engine has at least one exhaust gas aftertreatment device with an adjustable degree of efficiency (for example by changing the reduction agent) or an exhaust gas recirculation device or alternative variables for changing the raw engine emissions. At least one monitoring window is assigned to the active profile. The aim of the invention is to allow strict exhaust gas regulations to be met in particular during real driving operations while simultaneously allowing a low fuel consumption. This is achieved in that at least one main monitoring window of the driving profile and a sub-monitoring window (F2) with a starting point and an end point are defined within a driving profile or test cycle.
