MATLAB Lap Simulation Development

UT24 FSAE Vehicle - Custom Open-Source Simulation Framework

Project Overview

After a year of using OptimumLap, I recognized the limitations of off-the-shelf simulation software as UTFR began developing more sophisticated vehicle models. As the team transitioned to implementing correlated tire models from the TTC (Formula SAE Tire Test Consortium), I helped lead the development of a custom MATLAB-based lap simulation framework. This open-source approach allowed us to create highly customized models that accurately represented our electric FSAE vehicle's complex dynamics.

🚀 Further Development: Integrated Simulink Framework

This MATLAB foundation became the basis for our most advanced simulation platform. In 2025, we evolved this work into a comprehensive MATLAB Simulink framework that incorporates transient simulations, multi-physics coupling, and real-time analysis capabilities. The steady-state MATLAB lapsim provided here established the core methodologies that enabled this next-level development.

Transition from Commercial Software

The limitations of OptimumLap became apparent as our modeling requirements grew more complex:

  • Limited customization options for advanced tire models
  • Proprietary algorithms that couldn't be modified or validated
  • Difficulty integrating FSAE-specific electric vehicle characteristics
  • Lack of transparency in simulation assumptions and calculations
