Abstract

Hibridizacija gradskih autobusa ima velik potencijal u smislu smanjenja emisija štetnih i stakleničkih plinova te potrošnje goriva. Značajnu ulogu u tome bi mogla imati utična hibridna električna vozila (PHEV) koja bi se mogla puniti za vrijeme stajanja na krajnjim stajalištima te koja bi u većini voznog ciklusa koristila električnu energiju za pogon. Da bi se mogla razvijati strategija upravljanja tokovima energije PHEV-a te provoditi realistične simulacije ponašanja vozila potrebno je razviti detaljan dinamički model pogona uključujući uzdužnu dinamiku vozila, što je tema ovog rada. Za razvoj modela PHEV-a odabran je gradski autobus Volvo 7900 Electric Hybrid koji je paralelne (P2) konfiguracije. Model pogona izrađen je u programskom paketu LMS Amesim, te uključuje kvazistatičke modele motora s unutarnjim izgaranjem, motor/generator stroja i baterije te dinamičke modele suhe spojke s pneumatskim aktuatorom, automatizirane manualne transmisije i diferencijala s izračunom gubitaka zupčanog prijenosa te elastičnim poluvratilom. U modelu se koristi Pacejkin model gume i model uzdužne dinamike vozila. Za upravljanje pogonom s naglaskom na promjene stupnja prijenosa razvijena je podređena strategija upravljanja, koja je implementirana i zajedno s ostatkom modela ispitana za razne karakteristične režime rada automatske transmisije.

Abstract (english)

Hybridization of city busses has a large potential in reduction of harmful and greenhouse gas emissions and fuel consumption. Plug-in hybrid electric vehicles (PHEV) have a significant role in hybridization, because they can be recharged at the bus end stations, thus using mostly electric energy to propel the vehicle. For the purpose of developing a PHEV power flow control strategy and conducting realistic vehicle behaviour simulations, it is necessary to build up a detailed powertrain dynamics model including vehicle longitudinal dynamics, which is the main goal of this thesis. Volvo 7900 Electric Hybrid city bus, given in parallel (P2) configuration, is used as a platform for PHEV model development. The model is built up in LMS Amesim environment, and it includes quasi-static models of internal combustion engine, motor-generator unit and battery, as well as dynamic models of pneumatically-actuated dry clutch, automated manual transmission and differential with gear contact power loss and half shaft compliance accounted for, tyre model, and longitudinal vehicle dynamics model. A low-level control strategy that coordinates powertrain subsystems during gear shift events is developed and implemented into the overall model, which is then validated for different characteristic operating regimes of automatic transmissions.
