Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traffic flow coordination is performed only through inter-vehicle negotiation, then autonomous vehicles can coordinate maneuvers, but non-autonomous vehicles cannot participate and traffic flow efficiency deteriorates
Solution Approach 1:
The patent introduces a road side unit (RSU) as an intermediary entity that collects maneuver information from multiple vehicles, determines optimal maneuver sequences, and transmits coordinated maneuver commands to vehicles. This mediator enables non-autonomous vehicles to participate in traffic flow coordination without requiring them to perform complex negotiation algorithms, thereby improving both adaptability and traffic flow efficiency
2Ease of operation
If vehicles negotiate maneuvers autonomously without third-party coordination, then negotiation flexibility is maintained, but accident risk increases when negotiation fails or non-autonomous vehicles are involved
Solution Approach 1:
The RSU acts as a reliable third-party coordinator that receives maneuver requests from vehicles, determines safe and efficient maneuver sequences considering all affected vehicles, and transmits coordinated commands. This intermediary ensures accident prevention by centrally managing maneuver coordination, especially for non-autonomous vehicles that cannot negotiate autonomously, while maintaining flexibility through vehicle-initiated maneuver requests
3Reliability
If maneuver negotiation is performed between all vehicle pairs, then coordination completeness improves, but communication overhead and system complexity increase
Solution Approach 1:
The patent extracts the complex negotiation and coordination logic from individual vehicles and centralizes it in the RSU. Vehicles only need to send simple maneuver requests and receive coordinated commands, while the RSU handles the complex task of determining optimal maneuver sequences for all vehicles. This extraction significantly reduces system complexity while maintaining coordination completeness
