The invention relates to a method for model-based determination of a cylinder charge in a combustion chamber of an internal combustion engine, wherein the internal combustion engine has a variable valve lift which will be considered in the model-based determination, wherein the modeling of the cylinder charge of the combustion chamber is performed by at least one neuronal network (12), wherein at least three input values are input into the neuronal network. According to the invention, in the at least one neuronal network (12), a pressure quotient (c) is used as one of said at least three input values, wherein the pressure quotient (c) will at least indirectly be determined from a pressure (b) of the air sucked by the internal combustion engine and an operating pressure (a). 本发明涉及种用于对内燃机的燃烧室中的气缸充气进行基于模型的确定的方法，其中，内燃机具有在基于模型的确定中考虑的可变阀升程，其中，对燃烧室的气缸充气的建模由至少个神经网络(12)来执行，其中，至少三个输入值被输入到神经网络中。根据本发明，在至少个神经网络(12)中，压力商(c)被用作所述至少三个输入值中的个输入值，其中，压力商(c)将是至少间接地根据工作压力(a)和由内燃机抽取的空气的压力(b)来确定的。
