Platooning Vehicle BSM Relay Selection Under 5G Resource Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies do not efficiently utilize computing and communication resources during platooning, as they do not effectively determine a representative vehicle to transmit a basic safety message (BSM) based on resource usage.
Innovation Solution
A vehicular electronic device with a processor that acquires data on vehicle situations, determines if a vehicle is part of a platooning group, and designates a representative vehicle to transmit a BSM based on communication resource usage, ensuring efficient resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all vehicles in the group separately transmit BSM, then safety coverage is improved, but communication resource usage increases
Solution Approach 1:
Multiple follower vehicles merge their BSM transmission functions into a single representative follower vehicle. The representative follower vehicle collects BSM data from multiple follower vehicles and transmits consolidated safety information to nearby vehicles, reducing the total number of transmission sources while maintaining comprehensive safety coverage.
Solution Approach 2:
The representative follower vehicle performs multiple functions: it acts as a normal follower vehicle receiving control signals from the leader, collects BSM data from other follower vehicles, and transmits consolidated BSM to nearby vehicles. This multi-functionality reduces the need for separate dedicated transmission vehicles.
2Quantity of substance
If leader vehicle transmits BSM as representative, then communication resource efficiency is improved, but adaptability to dynamic situations deteriorates
Solution Approach 1:
The system dynamically switches between leader-based representation and follower-based representation depending on the situation. When the leader vehicle has sufficient communication resources, it transmits BSM as representative. When the leader's communication resources are constrained, a follower vehicle with adequate resources takes over as representative, ensuring continuous adaptability.
Solution Approach 2:
The system continuously monitors communication resource usage and transmission effectiveness. Based on feedback about resource availability and situational requirements, the system automatically determines whether the leader or a follower should transmit BSM, optimizing both efficiency and adaptability.
3Quantity of substance
If follower vehicle transmits BSM, then communication resource distribution is improved, but system complexity increases
Solution Approach 1:
The representative follower vehicle acts as an intermediary between multiple follower vehicles and nearby vehicles. Instead of each follower vehicle independently managing transmissions, the representative follower consolidates and relays BSM information, simplifying the overall system architecture while improving resource distribution.
4Quantity of substance
If representative vehicle is determined by communication resource usage, then resource efficiency is improved, but measurement precision requirements increase
Solution Approach 1:
Each vehicle autonomously monitors its own communication resource usage and determines whether it should serve as the representative transmitter. This self-service approach eliminates the need for complex centralized measurement and allocation systems, reducing the precision requirements for external measurement while maintaining resource efficiency.
