Virtuell implementering av platooning i Unity (Swedish)
Abstract [en]

Vehicle platooning is a technology that has gained attention from vehicle manufacturers in recent years. The interest lies mainly in the potential benefits this technology can bring. With the help of computer simulations, manufacturers can test how platoons behave under certain circumstances without having to spend money on building actual physical prototypes. By using the Unity game engine, an already existing simulation of a platoon is first visualized, letting all of the physics be controlled outside of Unity. Then the task is to explore the built in physics of Unity by either applying forces to vehicles or torques to the wheels. The results show that the simulations did not act as expected during these two test cases. This is mainly due to some limitations in precision of the underlying physics engine.

Abstract [sv]

Platooning av fordon är en teknologi som fått allt större uppmärksamhet de senaste åren. Intresset ligger framförallt i de potentialla fördelarna som platooning kan bidra med. Med hjälp av datorsimuleringar kan fordonstillverkare utföra tester på virtuella fordon utan att behöva spendera pengar på att bygga prototyper. Genom att använda Unity kunde först visualisering av en befintlig platoonsimulator ske där all fysik beräknades utanför spelmotorn. Därefter utfördes två testfall för att närmare undersöka den bekomliggande fysiken hos Unity, dels genom kraftapplicering på fordon, dels genom vridmomentsapplicering på hjul. Resultaten visar att simuleringarna har oväntade beteenden under de två testfallen. Detta beror framförallt på begränsingar i noggranheten i beräkningarna hos Unitys fysikmotor.
