“…The freight and passenger transport sector is expected to provide one of the largest contributions to the reduction of GHG emissions. In order to reduce emissions and diversify energy sources, alternative fuels have been promoted and suggested by a number of several particular methodologies at the national, EU, as well as global level, and have been discussed in a variety of research studies and publications [21][22][23][24][25][26][27][28].…”

The preference and the development of electromobility are included among the priorities of transport policies in many European countries. This article deals with the issue of electric vehicle operation from the point of view of the environmental impact of electric power production, specifically the energy effectiveness of its production by utilizing primary power production sources. Differences in the effectiveness of the conversion of mixed forms of energy into electricity and their share in the process directly affect the final level of greenhouse gases (GHG) production, and thus the ecological footprint of electric vehicle operations. The specification of energy consumption and GHG production is based on the principles of the EN 16 258: 2012 standard, which considers legislative-regulated power plant effectiveness values, statistical values of GHG emissions from electricity production, and real energy consumption values of an electric vehicle fleet. The calculation takes into account the share of primary sources and the efficiency of electricity production and effectiveness of electricity distribution in each of the evaluated countries. The specific research study is performed by comparing measured parameters for individual countries chosen from the Central Europe region. The results of the study show that the quantification of the positive environmental consequences of increasing electromobility varies greatly in different countries, which means full-scale deployment of electromobility does necessarily deliver the sustainability of transport that was expected from it.

“…The evaluation of the energy consumption and emissions of greenhouse gases of transport services must include the operational processes of the vehicle and the energy operational processes, which occur during the operational phase of its life cycle. The operational processes of a vehicle have to comprehend the operation of all the vehicle's systems including the propulsion and the complementary services [4,6,13].…”

Nowadays, the environmental aspects of transport are very actual issues, mainly the energy consumption and GHG production. The priority of EU transport strategy is to decrease the negative environmental impacts of all transport modes. The article discusses the calculation of the energy consumption and production of greenhouse gases in transport from both the primary and secondary points of view. This means, that it reflects the implications on the environment not only while operating the vehicle, but also during production, refining, distribution and storage of the fuel used in transport. The calculation is done by using the methodology of the standard EN 16 258:2012. This standard is used on all cars using various types of propellants. The results of the calculation show in a non-discriminatory manner the energy effectiveness of the individual types of fuel, as well as the rate of their production of greenhouse gases expressed in a comparison unit of equivalent CO2e.

“…These tests usually concern fuel and energy consumption by individual components of the drive system [20][21][22][23][24][25] and exhaust emissions [26][27][28][29][30][31][32]. For verification and comparative tests of different vehicles, it is necessary to reproduce identical or similar driving conditions [33][34][35][36]. Until now, chassis dynamometers with the possibility of simulating driving tests were used for this purpose.…”

The Concept of Determining Route Signatures in Urban and Extra-Urban Driving Conditions Using Artificial Intelligence Methods

The article describes the implementation of road driving tests with a vehicle in urban and extra-urban traffic conditions. Descriptions of the hardware and software needed for archiving the data obtained from the vehicle’s on-board diagnostic connector are presented. Then, the routes are analyzed using artificial intelligence methods. In this article, the reference of the route was defined as the trajectory of the driving process, represented by the engine rotational speed, the driving speed, and acceleration in the state space. The state space was separated into classes based on the results of the cluster analysis. In the experiment, five classes were clustered. The K-Means clustering algorithm was employed to determine the clusters in the variant without prior labelling of the classes using the teaching method and without participation of a teacher. In this way, the trajectories of the driving process in the five-state state space were determined. The article compares the signatures of routes created in urban and extra-urban driving conditions. Significant differences between the obtained results were indicated. Interesting methods of displaying the saved data are presented and the potential practical applications of the proposed method are indicated.
