VIRTUAL REALITY AND VEHICLE DYNAMICS IN UNREAL ENGINE ENVIRONMENT

Abstract

The paper is aimed on a vehicle dynamic simulation from scratch, using equations of motion solved by Runge-Kutta algorithm. The vehicle and a terrain interact in a game environment Unreal Engine, using line-trace functionality. All the scene objects are created in Creo Parametric, 3ds Max and Unreal Editor systems. The vehicle can be controlled by a keyboard and a racing steering wheel with pedals. The system allows free driving on the terrain in game-like style, recording and playback functions. All the computed parameters like vehicle’s locations, rotations, forces, velocities and accelerations can be recorded and saved into file during free drive. Then the data can be visualized in playback mode, with displayed forces, in 2D space and 3D by means of virtual reality headset HTC Vive. Virtual reality allows the user a full spatial view on the vehicle’s behavior.
