RSU-Based Maneuver Scheduling to Reduce V2X Logic Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle (V2V) and vehicle-to-everything (V2X) communication systems face challenges in ensuring safe and efficient vehicle maneuvers, particularly at intersections, due to incomplete sensor information and the need for advanced sensors on each vehicle, which increases costs and complexity.
Innovation Solution
A centralized scheduler-based mechanism using a Road Side Unit (RSU) for maneuver coordination, where vehicles request and receive maneuver instructions wirelessly, reducing the need for advanced sensors on individual vehicles and simplifying operation logic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicles use advanced sensors for maneuver coordination, then safety and reliability of vehicle maneuvers is improved, but device complexity and cost increases
Solution Approach 1:
The patent introduces a centralized scheduler as an intermediary component that coordinates vehicle maneuvers by receiving sensor information from vehicles and distributing coordinated maneuver instructions back to them. This mediator approach allows vehicles to achieve safe maneuver coordination without requiring complex advanced sensors on each vehicle, as the scheduling logic is centralized rather than distributed across all vehicles.
2Reliability
If each vehicle has complete sensor information for autonomous decision-making, then maneuver safety is improved, but device complexity and cost increases
Solution Approach 1:
The patent merges the sensor information processing and maneuver scheduling functions into a centralized scheduler that serves multiple vehicles. Instead of each vehicle maintaining complete sensor information independently, the system combines sensor data from multiple vehicles at a central point, processes it collectively, and generates coordinated maneuver instructions, thereby reducing individual vehicle complexity while maintaining overall safety.
3Ease of operation
If vehicles use distributed autonomous logic for maneuver coordination, then operational independence is improved, but logic conflicts between vehicles with different communication systems increase
Solution Approach 1:
The centralized scheduler acts as a mediator that receives maneuver requests from vehicles and provides coordinated instructions, ensuring consistent coordination logic across all vehicles regardless of their individual communication systems. This intermediary approach prevents logic conflicts by centralizing the decision-making authority while still allowing vehicles to operate independently based on received instructions.
Data Source
AI summary
The present disclosure provides for centralized, scheduler-based handling for UEs which transmit data to and receive data from a maneuver coordinator based on V2X communication. Once a UE is aware of the maneuver coordinator, the UE may send a request to the maneuver coordinator for maneuver operation scheduling. The maneuver coordinator then schedules and coordinates the UE's operation.
