Vehicle Convoy Communication Control for Predictive Link Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication systems face challenges in maintaining low latency and robustness, particularly in vehicle convoys, where interruptions can lead to collisions and convoy breakdowns due to inadequate proactive quality assurance.
Innovation Solution
A method that estimates future transmission quality between vehicles and initiates countermeasures to maintain or improve communication reliability by adjusting communication parameters and vehicle trajectories to ensure a minimum transmission quality, using a control device with an evaluation module to assess and adapt antenna configurations and vehicle positions for optimal data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current V2V communication systems are used in vehicle convoys, then data transmission occurs between vehicles, but communication reliability deteriorates due to interruptions and quality degradation
Solution Approach 1:
The system performs preliminary actions by estimating future transmission quality before actual communication degradation occurs. The evaluation module assesses anticipated transmission quality based on vehicle trajectories, antenna configurations, and environmental factors, enabling proactive countermeasures to be taken before communication interruptions happen, thus resolving the contradiction between reliability and stability
Solution Approach 2:
The system implements dynamic adaptation by continuously adjusting communication parameters and vehicle trajectories in real-time. The control device modifies antenna configurations, transmission power, and vehicle paths dynamically based on changing conditions, allowing the communication system to maintain reliability while adapting to stability challenges in the convoy environment
2Reliability
If communication parameters are adjusted to maintain transmission quality, then communication reliability improves, but system complexity increases
Solution Approach 1:
The system employs feedback mechanisms where the evaluation module continuously monitors transmission quality and feeds this information back to the control device. This closed-loop feedback enables automatic adjustment of communication parameters without requiring complex manual intervention, improving transmission quality while managing system complexity through automated control
Solution Approach 2:
The system manages complexity by focusing parameter changes on critical communication variables such as transmission power, antenna orientation, and frequency selection. Rather than adjusting all possible system parameters, the control device selectively modifies key parameters that have the greatest impact on transmission quality, thereby maintaining reliability without excessive system complexity
3Reliability
If vehicle trajectories are modified to improve line of sight, then transmission quality improves, but convoy coordination complexity increases
Solution Approach 1:
The control device performs multiple functions simultaneously: it manages communication parameters, coordinates vehicle trajectories, and maintains convoy formation. By integrating these functions into a single multi-functional control system, the patent improves transmission quality through trajectory adjustment without proportionally increasing coordination complexity, as the same control device handles multiple aspects of convoy management
