Review article

The article discusses the possibility of continuous monitoring of the technical condition of vehicles, namely, the composition of the exhaust gases. It is proposed to use a mechanism which allows, without installing additional sensors, to obtain information on the composition of the exhaust gases according to the results of the analysis of engine operating parameters available under the standard OBDII protocol. The use of artificial neural networks is described to analyze the results. The results of experimental studies confirming the hypotheses are given.
