Zusammenfassung:A method for ascertaining a mean value of a gas-mass flow in a combustion engine (2). The method includes measuring (S3) a gas-mass flow impinged upon by a pulsation, smoothing (S4) a sensor signal obtained by the measurement, applying (S6) a correction quantity to the smoothed sensor signal in order to obtain the mean value of the gas-mass flow, and ascertaining (S5) 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. 本发明涉及用于确定内燃机（2）中气体质量流量的平均值的方法，具有以下的步骤：- 测量（S3）利用脉冲加载的气体质量流量；- 平整（S4）通过测量获得的传感器信号；- 利用修正参量加载（S6）平整的传感器信号，以便获得气体质量流量的平均值；- 依据内燃机的运行状态，借助基于数据的、非参数的函数模型确定（S5）修正参量。
