High Fidelity Multibody Vehicle Dynamics Models for Driver-in-the-Loop Simulators

This document explores the development of high-fidelity multibody vehicle dynamics models for Driver-in-the-Loop (DiL) simulators using Dymola and Modelica. The research focuses on integrating advanced vehicle dynamics, suspension modelling, closed-loop driver models, and high-resolution LiDAR road data to create realistic real-time driving simulations for motorsport and road car applications.

The study introduces enhanced suspension and elastomer bush models, improved tyre-road interaction methods, and parallelised real-time simulation techniques, demonstrating how these technologies can accurately replicate vehicle handling, driver behaviour, ride comfort, and dynamic performance while supporting faster and more efficient vehicle development and optimisation processes.
