V2V Maneuver Coordination via Server Mediation

The patent extracts the negotiation process from traditional multi-vehicle V2V communication and relocates it to a server-based architecture. The server acts as a centralized coordinator that receives maneuver requests from vehicles and computes coordination solutions, eliminating the need for direct peer-to-peer negotiations among multiple vehicles. This extraction reduces network traffic and processing overhead at vehicle endpoints while maintaining maneuver coordination reliability.

The patent introduces a server as an intermediary between vehicles seeking to coordinate maneuvers. Instead of vehicles directly negotiating with each other, they communicate their maneuver requests and constraints to the server, which then computes the coordination solution and communicates it back to all involved vehicles. This intermediary approach simplifies the communication topology and reduces the computational burden on individual vehicles.

The patent implements preliminary action by having vehicles submit their maneuver requests, constraints, and preferences to the server in advance of the actual maneuver execution. The server pre-processes these requests and computes coordination solutions before the maneuvers need to be executed. This preliminary computation reduces the critical path latency during the actual maneuver window, as the coordination decision is already made and ready for implementation.

The patent uses copying by creating a virtual model of the maneuver coordination problem at the server. Instead of vehicles directly exchanging complex maneuver parameters and negotiating in real-time, the server creates a computational copy of the coordination problem, processes it using optimized algorithms, and returns the solution. This copying approach allows for more sophisticated coordination accuracy without the corresponding increase in real-time negotiation latency.
