Method for training an emission prediction model of an internal combustion engine

摘要

The invention relates to a method for training an emissions prediction model of an internal combustion engine. The method comprises a step of acquiring a first set of data comprising a plurality of pollutant gas emission measurements, one measurement being associated with at least one particular stabilized engine parameter, a step of acquiring a second set of data comprising, for a plurality of acquisition times during a real driving cycle, a measurement of pollutant gas emission associated with at least one engine parameter at the time of acquisition, a step of determining d '' at least one hyperparameter of the prediction model by cross-validation of training data from the first data set with validation data from the second data set, and a step of training the prediction model from the first set data and hyperparameter. The invention also relates to a method of predicting emissions from a model trained according to the training method. Figure 1
