Report on Current Developments in Autonomous Driving and Connected Vehicle Research
General Direction of the Field
The recent advancements in the field of autonomous driving (AD) and connected vehicle technologies are marked by a significant shift towards integrating Large Language Models (LLMs) and Generative Artificial Intelligence (GenAI) to enhance decision-making, perception, and communication capabilities. This integration is seen as a promising avenue to address the complexities and safety concerns associated with autonomous and cooperative driving systems. The field is moving towards creating more interactive, learnable, and trustworthy systems that can handle a wide range of scenarios, from urban traffic to vehicular networks.
One of the key trends is the development of LLM-driven frameworks that not only improve the reasoning and decision-making processes but also enhance the models' ability to learn from past experiences and adapt to new situations. This is particularly important for cooperative driving, where the synergy between connected autonomous vehicles (CAVs) can significantly enhance safety and efficiency. The introduction of memory modules and retrieval-augmented generation techniques in these frameworks allows for continuous learning and adaptation, making the systems more robust and versatile.
Another notable development is the focus on mitigating hallucinations and perception attacks in LLM-based AD systems. Researchers are exploring methods to self-check and verify the outputs of LLMs to ensure the accuracy and reliability of their decisions, especially in critical tasks like traffic understanding and object detection. This is crucial for maintaining the safety and compliance of AD systems in real-world scenarios.
The field is also witnessing a growing interest in the application of GenAI in the Internet of Electric Vehicles (IoEV), where generative models are being used to enhance various layers of vehicle systems, from battery management to security. This integration is expected to improve the efficiency and robustness of IoEV applications, paving the way for more advanced and interconnected vehicle networks.
