AI Technical Summary

Technical Problem

Existing vehicle platooning collaborative control systems suffer from problems such as insufficient data reliability, difficulty in identifying malicious nodes, lack of a unified and reliable data synchronization mechanism, control command real-time performance limited by communication latency, and insufficient real-time performance of blockchain applications, resulting in inadequate system security and stability.

Method used

A blockchain-based trusted collaborative control method for vehicle queuing is adopted. Through vehicle status perception and signature data broadcasting, data verification and consensus, dynamic trust value calculation, predictive control compensation and abnormal behavior detection and isolation, combined with a trust-weighted fusion predictive control mechanism, the queue structure is dynamically optimized to achieve highly secure and real-time collaborative control of vehicle queuing.

Benefits of technology

It improves the information security and synchronization reliability of vehicle platoon collaborative control, ensures the early identification and isolation of malicious nodes, dynamically adjusts the vehicle platooning order, enhances the collaborative control performance and anti-interference capability of the platoon, and improves the overall efficiency and security of the intelligent connected transportation system.
