Abstract

In a method for determining the air aspirated by an internal combustion engine, in which the air flow rate is detected by an air flow rate meter, simultaneously with the detection of the air flow rate, the humidity and/or pressure of the air is detected by a humidity and/or pressure sensor and evaluated in an evaluation circuit.
