Abstract
This paper presents a novel method for estimating the pollutants emitted by vehicles powered by internal combustion engines in real driving conditions, without the need for extensive measurement campaigns or the use of instrumentation in the vehicle for prolonged periods of time; for which it is based on the positioning and speed signals generated by the GPS (Global Positioning System) and the machine learning application. To obtain the data for training and validation of the model, two road tests are carried out using the Euro 6 directives for the estimation of pollutants through RDE (Real Driving Emissions), in which a portable emissions measurement system is used. and a logger that stores data from OBD (On Board Diagnostics) and GPS. From the data obtained in the first route, the performance of the vehicle is determined and through automatic learning, the model that estimates the polluting emissions is generated, which is validated with the data of the second route. When comparing the results generated by the model against those measured in the RDE, relative errors (%) of 0.0976, -0.2187, 0.2249 and -0.1379 are obtained in the emission factors of CO2, CO, HC and NOx, respectively. Finally, the model is fed with data obtained in 1218 km of random driving, obtaining similar results to OBD-based models and closer to the real traffic conditions generated by models such as IVE (International Vehicle Emissions). Obtaining data through the OBD and GPS present in current vehicles is cheap and the application of automatic learning models for the estimation of polluting emissions is an option that opens up a field of work without the need for on-board equipment. more expensive acquisition costs to carry out experimental campaigns on limited samples of vehicles due to the associated costs.
