Abstract
A method for ascertaining a mean value of a gas-mass flow in a combustion engine. The method includes measuring a gas-mass flow impinged upon by a pulsation, smoothing a sensor signal obtained by the measurement, applying a correction quantity to the smoothed sensor signal in order to obtain the mean value of the gas-mass flow, and ascertaining the correction quantity as a function of the operating state of the combustion engine with the aid of a data-based, non-parametric function model.
