Abstract

A method for providing a characteristic quantity for a state of an air system of a supercharged internal combustion engine includes: detecting a characteristic quantity measured value as characteristic quantity information with the aid of a sensor; providing a characteristic quantity model, using which a characteristic quantity model value is computed on the basis of one or more quantities different from the characteristic quantity measured value; and providing the characteristic quantity either based on the characteristic quantity measured value or on the characteristic quantity model value computed by the characteristic quantity model, as a function of a state of the air system.
