Integrating large models (LMs) into future vehicles and transportation systems marks a significant advancement in mobility and transportation technology. Incorporating artificial intelligence and machine learning, these LMs are poised to revolutionize various aspects of transportation. This paper proposes LMs-based approaches for cooperative control and coordination of connected and autonomous vehicle (CAV) fleets. Specifically, algorithms based on the alternating direction method of multipliers (ADMM) are developed for distributed optimization of CAV trajectories. The synchronous ADMM and asynchronous ADMM algorithms enable parallelized coordination of large-scale CAV systems. Simultaneously, we propose a distributed training scheme where each CAV trains its cost and dynamics networks on simulators local to each vehicle. A central coordinator interacts with the vehicles to tune the coupling networks. Then, we introduce an innovative car-following model named the integrated velocity and acceleration fusion model that integrates state information from multiple lead and following vehicles to determine the optimal acceleration for the subject CAV. While we utilize graph sample and aggregate –based neural network and the gated recurrent unit and propose a model for recognizing driving intentions and predicting the trajectories of surrounding vehicles based on these theories. Simulation results demonstrate enhanced traffic efficiency, safety, robustness, and scalability using LMs for cooperative control of CAV. IEEE
