V2X Group Information Updates for Platoon Leader Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current V2X communication systems lack methods for efficiently updating group leaders in vehicle platoons, particularly in on-network and off-network scenarios, and for non-member vehicles to request group membership changes based on specific criteria.
Innovation Solution
A method and system for updating group information using a Vehicle to Everything (V2X) Application Enabler (VAE) server and clients to manage group leader changes and membership requests through consent-based communication protocols, involving parameter evaluation and notification across V2X User Equipments (UEs) and servers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the platoon leader continuously monitors and updates group information in real-time, then the reliability of platoon management is improved, but the resource consumption and complexity of the system increases
Solution Approach 1:
The patent introduces a VAE server as an intermediary between V2X UEs and the platoon management system. The server handles group information updates, leader changes, and membership management centrally, reducing the complexity burden on individual vehicles while maintaining reliable real-time monitoring and control of the platoon.
2Loss of information
If the platoon leader updates group information frequently to maintain real-time awareness, then the information freshness is improved, but the network traffic and energy consumption increase
Solution Approach 1:
The system implements periodic group information updates through the VAE server, which efficiently manages when and how information is refreshed. This periodic approach maintains information freshness by updating only when necessary, rather than continuous updates, thereby reducing energy consumption and network traffic while preventing information loss.
3Adaptability or versatility
If non-member vehicles can request group membership based on arbitrary criteria, then the adaptability of the platoon system is improved, but the security and control of the group management deteriorates
Solution Approach 1:
The VAE server implements a feedback mechanism where non-member vehicles can submit membership requests with specific criteria, and the server evaluates these requests against predefined security policies and group requirements. This feedback loop maintains adaptability by allowing flexible membership applications while preserving control through centralized validation and approval processes.
