V2X Alert System Using Map Data to Reduce False Alarms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing V2X communication systems generate false or missing alarms for drivers due to the lack of real-world mapping information in their baseline applications, leading to potential collisions, lane obstructions, and navigation errors.
Innovation Solution
A system and method that incorporate real-world mapping data into V2X applications, using a communication unit and controller to provide alerts based on vehicle-to-x communication data and geographic mapping information, enhancing the interpretation of Basic Safety Messages (BSMs) to reduce false and missing alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If real-world mapping data is integrated into V2X systems, then measurement precision and reliability of alerts are improved, but device complexity increases
Solution Approach 1:
The patent introduces map data as an intermediary layer between raw BSM data and alert generation. The map data provides contextual information about road geometry, intersections, and geographic features, allowing the system to accurately interpret BSM data without requiring direct complex processing of all possible scenarios. This mediator enables precise alert generation while managing system complexity through structured data integration.
Solution Approach 2:
The system performs preliminary actions by pre-loading and storing map data in advance before V2X communication occurs. This allows the system to have contextual geographic information readily available when BSM data arrives, enabling immediate and accurate alert generation without real-time computation of geographic contexts, thus improving precision while managing processing complexity.
2Reliability
If map data is used to interpret BSMs, then false alarms are reduced, but information processing requirements increase
Solution Approach 1:
The patent extracts only the essential and relevant features from map data that are necessary for interpreting BSMs, such as road boundaries, intersection locations, and geographic constraints. By extracting only these critical elements rather than processing complete map datasets, the system reduces false alarms through better contextual understanding while minimizing the information processing load to only what is essential for reliable alert generation.
3Device complexity
If V2X communication is implemented without map data, then device complexity is reduced, but false alarms and missing alarms increase
Solution Approach 1:
The patent implements a universal alert generation system that can operate with or without map data, adapting its functionality based on data availability. The core BSM interpretation mechanism serves as a universal base that can be enhanced with map data when available, providing reliable alerts in both simplified and enhanced modes. This multi-functionality allows the system to maintain alert reliability across different operational scenarios while managing complexity through optional enhancement.
