Vehicle-to-X Communication Module Reception Quality Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-X communication systems lack effective methods to ensure the availability and reliability of communication signals, particularly in assessing reception quality, which is crucial for autonomous control and safety in traffic management.
Innovation Solution
A method for determining the reception quality of vehicle-to-X messages by calculating the ratio of received pilot tones to messages, packet error rates, and signal-to-noise ratios, using central servers, on-board maps, and feedback from other vehicles to provide reliable information for downstream processing units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle-to-X communication is implemented without reception quality assessment, then communication simplicity is maintained, but reliability and safety for autonomous control cannot be ensured
Solution Approach 1:
The patent implements reception quality assessment by evaluating feedback signals (pilot tones) transmitted alongside vehicle-to-X messages. The receiving vehicle measures the strength and quality of these feedback signals to determine reception quality metrics, which are then used to assess the reliability of the received message before autonomous control actions are taken.
Solution Approach 2:
The patent performs reception quality assessment before the message is processed for autonomous control. By evaluating pilot tones and signal characteristics in advance, the system determines whether the message meets reliability thresholds before triggering control actions, preventing unsafe operations based on poor-quality communications.
2Measurement precision
If reception quality is determined using multiple parameters (pilot tones, packet error rate, signal-to-noise ratio), then measurement precision of reception quality improves, but processing time and computational complexity increase
Solution Approach 1:
The patent evaluates multiple reception quality parameters including pilot tone strength, packet error rate, and signal-to-noise ratio simultaneously. By assessing all available quality metrics together rather than sequentially, the system achieves comprehensive measurement precision while minimizing total processing time through parallel evaluation of different quality indicators.
