Digitalization method for calculating vehicle exhaust emissions

Abstract

Exhaust gases emitted by vehicles have a significant negative impact on environmental sustainability and the environment, accounting for a significant share of the total emissions. Therefore, large-scale research and practical measures are being carried out around the world to reduce the negative effects of these emissions and effectively manage them. Along with the gradual tightening of the EURO environmental requirements developed and implemented by the United Nations, test methods used to determine exhaust emissions are constantly being improved, and the technical level of testing equipment is aimed at ensuring high accuracy, speed and reliability. In particular, taking into account the above environmental requirements in the production of cars, the environmental safety of the design is assessed using modern test methods based on international standards, such as dynamometers, PEMS (Portable Emission Measurement System), WLTP (Worldwide Harmonized Light-Duty Vehicles Test Procedure) and RDE (Real Driving Emissions). However, the process of measuring the composition of exhaust gases of operating vehicles is labor-intensive, time-consuming and expensive, which makes it difficult to carry out emission measurements on a large number of vehicles. The development of a digital method for monitoring exhaust gases using data from the electronic control unit (ECU) of operating vehicles is currently relevant. This article proposes a method for determining the amount of CO2 in exhaust gases per unit of mileage by digitalizing the vehicle ECU data.
