1. A method for characterizing an air mass flow rate target in an internal combustion engine, comprising the steps of:

  • determining a reference air mass flow rate term;

    determining an engine rotational speed term;

    determining a compressibility term as a function of said engine rotational speed term; and

    processing said reference air mass flow rate term and said compressibility term to determine the air mass flow rate target.
