Multi-domain Simulation of Hybrid Vehicles

This document explores the use of Dymola and Modelica for high-fidelity multi-domain simulation of hybrid and motorsport vehicle systems, integrating mechanical, electrical, thermal, hydraulic, magnetic, and control-domain models within a unified simulation environment.

The research focuses on hybrid powertrain development, including internal combustion engines, electric motor generator units (MGUK and MGUH), energy storage systems, cooling circuits, chassis dynamics, and thermal management for Formula 1-style Energy Recovery Systems (ERS). By combining predictive physical models, advanced electric machine representations, and real-time capable vehicle dynamics simulations, the study demonstrates how multi-domain modelling can support optimisation of vehicle efficiency, thermal performance, control strategies, drivability, and system integration while reducing development time and physical prototyping requirements.
