| Abstract: | This study contributes insights into the intersection of reinforcement learning (RL), sim(ulation) racing, and autonomous driving, specifically within Assetto Corsa (AC) as a sim racing environment. The difference in RL algorithms is explained with a reasoning for the suitability of the Soft-Actor-Critic (SAC) algorithm for an autonomous car racing agent in AC. Based on this, a system design is presented for using AC as an experimentation environment for training the model-free, off-policy SAC algorithm. Specific policy details, hyperparameters, and reward factors are discussed in the context of addressing the lap-completion problem. Here, the objective is to find a policy that achieves completion of a given track with a given car. Results are presented for five different reward functions, on which we conclude the fifth (using the heading and off-center errors) to be the most effective. Future steps for research are laid out with the goal of actually completing a full lap, and ultimately optimizing the minimum-time problem as well. Here the goal is not only to finish, but finish with minimal time. |
