Abstract
A method for determining a corrected air mass flow value in an engine having an air mass meter in its intake. The method includes determining a cold start condition of the engine at a first time when there is no air mass flow in the intake tract, producing a reference signal by the air mass meter at the first time, and determining an air mass flow offset from the reference signal, producing a measurement signal by the air mass meter at a second time, which is not equal to the first time, which is in an operating period of the engine, determining an air mass flow value from the measurement signal, and determining a corrected air mass flow value from the air mass flow offset and the air mass flow value.
