A method and apparatus and computer program for controlling an internal combustion engine

There are proposed a method and an apparatus and a computer program for controlling an internal combustion engine, a torque model is used in the calculation of actual values ​​and / or manipulated variables. Thereby correcting a base value determined under standard conditions is made. Further, to further improve the accuracy of the model is determined at least dependent on a combustion center of gravity characterizing size and of a opening timing of an exhaust-side gas exchange valve variable characterizing the efficiency of the conversion of the chemical energy into mechanical energy, with which the optimum torque value is corrected.
