Abstract (Croatian)

Zagađenje okoliša, efekti staklenika i potencijalna nestašica fosilnih goriva predstavljaju trenutne globalne probleme u svijetu. Direktna posljedica tih problema jest moderni tijek razvoja automobilske industrije, koja se smatra odgovornom za navedene probleme. Nadalje, u svijetu postoji ideja elektrifikacije te stapanja elektro-energetskog sustava s transportnim sustavom. Kao rješenje trenutno se nude hibridna električna vozila. Jedna od ključnih izazova kod razvoja hibridnih električnih vozila jest optimalna raspodjela energije na pogonskim sustavima, koja će minimizirati potrošnju goriva i emisiju štetnih plinova. Za danu arhitekturu pogona hibridnog električnog vozila, potrebno je razviti nadređenu strategiju upravljanja koja će raditi navedenu raspodjelu energije. Tema ovog rada upravo jest sinteza i simulacija strategije upravljanja umjereno-hibridiziranim električnim vozilom paralelne arhitekture P2. Umjereno-hibridizirano električno vozilo nudi razne mogućnosti razvoja hibridnih funkcionalnosti, koje će na temelju nadređenog sustava upravljanja smanjiti potrošnju goriva i emisiju štetnih plinova. Kroz ovaj rad prestavljen je unazadni i dan unaprijedni matematički model umjereno-hibridizanog električnog vozila unutar AVL CRUISE-a. Zatim je provedena sinteza i implementacija hibridnih funkcionalosti kao što su asistiranje momentom (eng. Torque Assist), pojačavanje momentom (eng. E-Boost), pomicanje radne točke u vertikalnom smjeru (eng. Load Point Moving) i pomicanje radne točke u horizontalnom smjeru (eng. Load Point Shifting). Razvijene funkcionalnosti su integrirane u jedan zajednički model te je proveden odziv na nekoliko certifikacijskih voznih ciklusa u svrhu analize smanjenja potrošnje goriva. Kasnije je razvijen ko-simulacijski model unutar AVL Model.CONNECT-a sa složenijim modelom motora s unutarnjim izgaranjem unutar AVL CRUISE M-a. Odziv ko-simulacijskog modela proveden je na istim certifikacijskim voznim ciklusima, kao što je bio slučaj i s osnovnim modelom.

Abstract

Environment pollution, greenhouse effect, and the potential fossil fuel scarceness represent the current global problems worldwide. The direct consequence of those problems is the modern course of development of the automotive industry, which is considered responsible for those problems. Also, the idea of electrification and the electrical energy system amalgamation with the transport system is present nowadays. Hybrid electric vehicles are currently being offered as a solution to these problems. One of the key aspects of hybrid electric vehicles development is the optimal energy management of the power sources, which is aimed to minimize fuel consumption and harmful gas emissions. For a given powertrain architecture, it is necessary to develop a supervisory control strategy which will carry out the energy management within the system. The topic of this thesis is the design and simulation of a control strategy for a mild hybrid electric vehicle given in parallel architecture P2. The mild hybrid electric vehicle offers a fair amount of hybrid functionalities development, which will ensure fuel economy gains and harmful gas emissions reduction. Through this thesis, a backward powertrain model was developed, and the forward powertrain model was given within the AVL CRUISE environment. Then the design and implementation of hybrid functionalities such as Torque Assist, E-Boost, Load Point Moving, and Load Point Shifting were carried out. The developed functionalities were integrated into one model. Model's response was tested on several certification driving cycles for the fuel consumption analysis purposes. Later on a Co-Simulation model within the AVL Model.CONNECT was developed, with a more complex internal combustion engine model taken from the AVL CRUISE M. The Co-Simulation response was carried out on the certification driving cycles as it was the case with the basic CRUISE model.
