Abstract
A method and a device for controlling a gas fill of a plurality of cylinders in an internal combustion engine having variable valve timing, in which a detection signal of a filling sensor is sampled with a sampling rate. Furthermore, a detection interval is determined for one cylinder. The sampling values for ascertaining a sampling-value sum are added up within this detection interval. In addition, a number of sampling values within the first detection interval are counted for ascertaining a first count value. The air mass filled into the first cylinder is then ascertained by forming a quotient from the sampling-value sum and the count value.
