Abstract

Minimum lap time simulations are of great interest for the design and setup of race vehicles. These problems can be formulated and solved in various methods, like quasi-steady state models vs full dynamic models and predefined (fixed) trajectory problems vs free trajectory problems.
This work focuses on full dynamic models with free trajectory, that are the most appealing and challenging. This kind of problems can be solved using Optimal Control theory, that give rise to two numerical solving approaches: indirect and direct methods, the latter being the most widespread and used approach. This work aims to compare indirect and direct methods when applied to minimum lap time simulations, in order to understand the differences between the two approaches and whether one is more suitable than the other.
