Försäljningen av trehjuliga motorcyklar beräknas att öka de kommande åren. Efterfrågan ökar framför allt på eldrivna trehjuliga motorcyklar. För att lyckas i fordonsbranschen behöver fordonen som utvecklas vara säkra. Säkerhet är av hög prioritet i utvecklingen av Omotion AB:s fordon. OMotion har två problem med sin senaste trehjuliga motorcykel där lösningarna kan bidra till ökad säkerhet. Instrumentpanel bakom ratt skyms när ratten vrids. Föregående modell av styrsystemet interagerar ej med 3D-modellen av fordonet på ett verklighetstroget sätt. Nytt koncept med prototyp av display tas fram med en produktutvecklingsprocess. Produktutvecklingsprocessen innefattar en konceptutveckling, utveckling på systemnivå, detaljutveckling och testning. 3D-modell för nytt styrsystem som interagerar på ett korrekt sätt tas fram med CAD-programmet SolidWorks. Enklare fysikaliska beräkningar utförs med kunskap inom hållfasthetslära och maskinelement. Resultatet är lösningar på OMotions två problem. En fysisk och analytisk prototyp för rattens integrerade display är framtagen samt en verklighetstrogen 3D-modell av styrsystemet. Styrsystemsmodellen möjliggör styrning av motorcykelmodellen i SolidWorks. / Sales of three-wheeled motorcycles are expected to increase in the coming years. Demand is increasing, especially for electric tricycles. To succeed in the automotive industry, the vehicles that are developed need to be safe. Safety is a high priority in the development of Omotion AB’s vehicles. OMotion has two problems with its latest three-wheeled motorcycle Where the solutions can contribute to increased safety. The dashboard behind the steering wheel is obscured when the steering wheel is turned. The previous model of the steering system does not interact with the 3D model of the vehicle realistically. New concept with prototype of display is developed with a product development process. The product development process includes a concept development, development at system level, detailed development and testing. 3D model för a new control system that interacts correctly is developed with the CAD program SolidWorks. Simpler physical calculations are performed with knowledge in solid mechanics and machine elements.The results are solutions to OMotion’s two problems. A physical and analytical prototype for the steering wheel’s integrated display has been developed, as well as a realistic 3D model of the steering system. The steering system model enables control of the motorcycle model in SolidWorks

Vehicle simulators are often built from scratch, using well-established software frameworks with custom vehicle models. Since the development of a simulator is a very time consuming process,  the purpose of this thesis paper was to explore a different alternative by evaluating the open-source vehicle system ChaosVehicle (CV) in Unreal Engine 5. The goal was to build a simulator using CV and assess its performance in imitating certain aspects of a three-wheeled electric vehicle, including acceleration, coasting and braking behaviors in a straight line.The simulator was set up according to the data provided by the vehicle manufacturer, OMotion. By comparing the simulations with real world driving data, it was determined that the simulator achieved a relative error below 16% in imitating the coasting behavior of the real vehicle. Further, with regards to the brake performance, the simulator has managed to achieve a relative error of below 15% when not accounting for velocities below 10 km/h. Due to the noise present in the real world driving data, it was inconclusive as to whether the simulator had accurately predicted the acceleration behavior of the  real vehicle. After a preliminary analysis of the plugin, it was discussed whether CV was as extensible as hypothesized. While the framework is open-source, it was difficult to fully grasp the system due to incomplete documentation of the source code and the user interface. Further work in mapping how the physics model in CV is integrated to the game engine would shed some light on this matter.
