ABSTRACT:
A method for model-based determination of the total fresh air mass flowing into the cylinder combustion chamber of an internal combustion engine during an intake phase is described. The method includes, steps of ascertaining a first partial air mass on the basis of a first load partial model, the first load partial model having a linear behavior, ascertaining a second partial air mass on the basis of a second load partial model, the second load partial model having a nonlinear behavior, and determining the total air mass by adding together the previously ascertained partial air masses.
