Abstract: With the rapid development of the esports industry, racing games have become a key focus for both academic research and industrial applications. However, traditional racing game artificial intelligence (AI) struggles to adapt to increasingly complex track environments and meet evolving player demands. Deep Reinforcement Learning (DRL) has shown great promise in enhancing AI’s environmental perception and strategy optimization, yet its application in racing games remains in an exploratory phase, hindered by high data demands, slow convergence, and poor generalization. To address these challenges, this paper proposes a novel racing AI training method that combines voxel-based track feature extraction, fuzzy Deep Q-Network (DQN), and imitation learning. Voxelization enables the AI to automatically extract key track features, while fuzzy DQN refines speed adjustment strategies for better performance in complex environments. The inclusion of imitation learning reduces reliance on expert data, significantly accelerating training convergence. Experimental results demonstrate that the proposed method outperforms traditional algorithms like DQN, Q-Learning, and SARSA. Specifically, the custom algorithm achieved a 25% faster convergence rate, with a final total reward of around 400, compared to approximately 300 for DQN and 250 for SARSA. Additionally, the loss values were reduced by 60% in the final stages of training, indicating improved stability and learning efficiency. These results confirm that the proposed approach not only enhances AI training efficiency in racing games but also holds potential for real-world autonomous driving applications.
