Abstract

Tema ovog završnog rada je, putem programskog i simulacijskog okruženja, ispitati uštede koje električno vozilo, s nezavisnim pogonom na četiri kotača, ostvaruje za karakteristične uzdužne i bočne manevre vožnje kojima je podvrgnuto. Energetski učinkovit način upravljanja postiže se usmjeravanjem okretnog momenta na pojedini kotač te je pri ovako zamišljenom modelu vozila ono izrazito primjenjivo budući da osovinu svakog kotača pogoni jedan zaseban sinkroni elektromotor. U radu je prije svega cjelovito opisan model dinamike vozila, a zatim su prikazane karakteristike elektromotornog pogona s obzirom na gubitke te pomoću simulacijskog modela elektromotornih pogona i modela dinamike vozila, postavljen je zakon usmjeravanja momenta. Naposljetku su simulacijom bočnih i uzdužnih manevara provedene analize ušteda energije upravljanog vozila u odnosu na vozilo s jednakim pogonom na sva četiri kotača te analize prikazane grafički i tablično.

Abstract (english)

The topic of this final paper is to investigate the savings achieved by an electric vehicle with independent four-wheel drive through a programming and simulation environment, considering typical longitudinal and lateral driving maneuvers to which it is subjected. An energy-efficient method of vehicle control is achieved by torque vectoring technology, which is highly applicable in this envisioned vehicle model, as each wheel axle is driven by a separate synchronous electric motor. The paper primarily describes vehicle dynamics model in detail, and then presents the characteristics of an electric drive, in terms of losses. Using a simulation model of electric drives and the vehicle dynamics model, a torque control allocation strategy is established. Finally, through simulation of lateral and longitudinal maneuvers, analyses of energy savings in controlled vehicle compared to the vehicle with equal distribution on all four wheels are conducted, and the results are presented graphically and in tabular form.
