Abstract

Ein Fahrzeugsystem umfasst einen Drosselklappenstellungssensor, der ein Signal (TP) der momentanen Drosselklappenstellung erzeugt, einen Luftmassendurchflusssensor (MAF-Sensor), der ein Signal des momentanen Ist-MAF erzeugt, und einen Krümmerabsolutdrucksensor (MAP-Sensor), der ein Signal des momentanen Ist-MAP erzeugt. Eine Steuereinheit bestimmt ein Signal (CAF¶E¶) des momentanen geschätzten Zylinderluftdurchflusses (CAF), ein MAF-Übergangssignal und ein MAP-Übergangssignal. Die Steuereinheit bestimmt ein Signal (CAF¶P¶) des vorhergesagten CAF in den Motor anhand des Signals (CAF¶E¶) des momentanen geschätzten CAF, des Signals des momentanen Ist-MAF, des Signals des momentanen MAP, des Signals der momentanen TP, des MAF-Übergangssignals und des MAP-Übergangssignals.
