Abstract

A method for determining a modeling value of a physical variable in a gas guiding section of an engine system including an internal combustion engine, includes the following steps: operating the engine system in such a way that an air mass flow is present in the gas guiding section; determining instantaneous values of other physical variables; and determining the modeling value of the physical variable by solving a differential equation, which results as the discretization of a differential equation, with the aid of the previously ascertained instantaneous values of the other physical variables.
