Controlling an internal combustion engine using an operating parameter map derived from a trainable model

A method for operating an engine control system of an internal combustion engine of a vehicle, comprising:

• setting, based on a predefined multidimensional operating parameter map which specifies respective operating parameter values for various operating states of the internal combustion engine, one or more operational parameters of the internal combustion engine by the control unit;
• transmitting an operating parameter history, which comprises operating parameter values set for the internal combustion engine in its operating history, by the control unit to a learning unit;
• receiving operating parameter map update data by the control unit from the learning unit;
• and
• updating the stored operating parameter map by means of the received operating parameter map update data, by the control unit, wherein
• a simulation model of the internal combustion engine and a target function for evaluating the behavior of the internal combustion engine are stored in the learning unit, wherein the simulation model is trainable by a learning algorithm stored in the learning unit, and the learning unit is designed
• (i) to update the simulation model based on the transmitted operating parameter history and the stored target function by utilizing the learning algorithm;
• (ii) to generate the operating parameter map update data by the updated simulation model;
• or
• (iii) to provide the operating parameter map update data to the control unit for updating the operating parameter map stored in the control unit.
