Abstract

U posljednjem desetljeću znatno je porasla zastupljenost električnih vozila na tržištu automobila, s ciljem smanjenja emisija štetnih plinova. Porastu popularnosti i zastupljenosti električnih vozila pridonijelo je orijentiranje proizvodnje električne energije prema obnovljivim izvorima energije i napredak u tehnologiji baterija. Zadržavanje konkurentnosti na tržištu električnih vozila koje se svakodnevno razvija zahtjeva brzo prilagođavanje promjenama i kontinuirano unaprjeđenje sustava vozila. U svrhu brzog stjecanja točnih informacija o tehnologijama koje će se potencijalno primijeniti u vozilu, koriste se simulacijski modeli vozila. U ovom radu se razmatra optimalan način upravljanja pogonom električnog vozila sa četiri nezavisna elektromotora kako bi se postigla maksimalna učinkovitost komponenti pogona, s ciljem smanjenja potrošnje električne energije, odnosno povećanja dometa te smanjenja potrošnje. Model pogona izrađen je u ko-simulacijskom okruženju u programima MATLAB / Simulink, i IPG CarMaker. Postavljeno je pet strategija upravljanja pogonom vozila koje su simulacijski ispitane na WLTP voznom ciklusu. Rezultati pokazuju povećani domet vozila uslijed implementacije nove upravljačke logike kojom se stražnji pogon isključuje pri niskim brzinama vozila.

Abstract (english)

Throughout the last decade, the presence of electric vehicles in the car market has increased significantly, with the aim of reducing harmful gas emissions. The main contributors to the increased market share are orientation of electricity production towards renewable energy sources and advances in battery technology. Maintaining competitiveness in the market that is continuously evolving requires the ability to quickly adapt to changes and continuously improve the product, which must be thoroughly tested and verified before entering the market. In order to quickly evaluate the technologies that could potentially be applied in the vehicle, numerical simulations of the vehicle and its subsystem are typically used. This thesis discusses the optimal way to control the powertrain of a vehicle with four independent electric motors to achieve highest efficiency of the powertrain components and thus reduce consumption during a homologation cycle and increase driving range. The vehicle model is set up in MATLAB / Simulink and IPG CarMaker co-simulation environment. Five powertrain control systems are evaluated on WLTP driving cycle. The results point out that completely disengaging the rear wheels reduces power consumption to the greatest extent.
