20.500.12556/RUL-139764 Model za določitev porabe energije in izpustov CO2 med vožnjo avtobusa Model for determining energy consumption and CO2 emissions during driving of a bus V zadnjih desetletjih se je svetovna poraba fosilnih goriv znatno povišala, kar je vplivalo na količino izpustov CO2. Velik del skupnih izpustov CO2 proizvede prometni sektor, zato se v diplomskem delu osredotočamo na napredne načine pogonov vozil z nižjo porabo energije in nižjimi izpusti CO2 v primerjavi s konvencionalnim pogonskim sistemom z motorjem z notranjim zgorevanjem. Primerjamo pogonski sistem z električnim strojem, pogonski sistem z motorjem z notranjim zgorevanjem in hibridni pogonski sistem. Ti pogonski sistemi so ovrednoteni z računskim programom, ki je bil v sklopu diplomskega dela namensko razvit v programskem jeziku Python. Računski program omogoča izračun porabe energije in izpustov CO2 pogonskega sistema tekom voznega cikla. Za izračun porabe energije in izpustov CO2 pogonskega sistema težkih vozil se uporabijo industrijsko sprejeti vozni cikli, na primer Braunschweig, CSHVC in ETC. V sklopu računskega programa je bil ustvarjen grafični vmesnik, ki omogoča nastavitev lastnosti simuliranega vozila in prikaz rezultatov. V okviru diplomskega dela je bila izvedena validacija računskega programa z industrijsko sprejetim programom AVL Cruise M. Hkrati je bila tekom diplomskega dela opravljena primerjalna analiza z namenom primerjave pogonskih sistemov za avtobuse medkrajevnega javnega potniškega prometa, kjer smo ugotovili, da hibridni pogonski sistem in pogonski sistem z elektromotorjem med delovanjem porabita precej manj energije v primerjavi s pogonskim sistemom z notranjim zgorevanjem. Hkrati ugotavljamo, da hibridni pogonski sistem proizvede precej manj izpustov CO2 v primerjavi s pogonskim sistemom z motorjem z notranjim zgorevanjem. In recent decades, the global consumption of fossil fuels has increased significantly, which has affected the amount of CO2 emissions. A large part of the total CO2 emissions is produced by the transport sector, so in this thesis we focus on advanced drive systems for vehicles with lower energy consumption and lower CO2 emissions compared to a conventional drive system with an internal combustion engine. We compare the drive system with an electric machine, the drive system with an internal combustion engine and the hybrid drive system. These drive systems are evaluated with a calculation program that was specifically developed in the Python programming language as part of the thesis. The computer program enables the calculation of energy consumption and CO2 emissions of the drive system during the driving cycle. Industry-accepted driving cycles such as Braunschweig, CSHVC and ETC are used to calculate the energy consumption and CO2 emissions of the drive system of heavy-duty vehicles. A graphical interface was created as part of the calculation program, which allows setting the properties of the simulated vehicle and displaying the results. As part of the thesis, the validation of the calculation program was carried out with the industry-accepted AVL Cruise M program. At the same time, in the course of the thesis, a comparative analysis was made with the aim of comparing drive systems for buses of intercity public passenger transport, where we found that the hybrid drive system and the drive system with an electric motor consume much less energy during operation compared to the drive system with internal combustion engine. Nevertheless, we find that the hybrid drive system produces significantly less CO2 emissions compared to the drive system with only internal combustion engine. simulacija pogonskega sistema primerjava avtobusov z različnimi pogonskimi sistemi vozilo z električnim pogonskim sistemom vozilo z motorjem z notranjim zgorevanjem vozilo s hibridnim pogonskim sistemom drivetrain simulation comparison of busses with different drivetrains electric vehicle vehicle with conventional drivetrain hybrid vehicle drive cycles true false false [A.
