Abstract

A method for determining at least one air system variable in an air supply system of an internal combustion engine in successive, discrete calculation steps, a differential equation being provided with respect to the air system variable based on measured and/or modeled variables, which describe conditions in the air supply system, a difference equation being formed for the quantization of the differential equation according to an implicit method, and the difference equation being solved in each discrete calculation step, in order to obtain the air system variable.
