V2X Vehicle Location Tracking With Distributed Sighting Reports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cellular-based vehicle tracking methods provide limited location granularity, and there is a need for more precise tracking of vehicles in situations like vehicle theft or accidents using Vehicle to Everything (V2X) communication.
Innovation Solution
A method and network element within the V2X Communications Domain that receives a tracking request, creates a target vehicle list, distributes it to V2X endpoints, and forwards sighting reports to facilitate precise vehicle tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cellular-based tracking is used, then tracking coverage is provided, but location granularity is limited to cell level
Solution Approach 1:
The patent introduces V2X communication as an intermediary layer between cellular tracking and vehicle location. V2X endpoints in vehicles continuously broadcast their locations, and a V2X application server collects and manages these broadcasts, providing cell-level granularity without requiring complex cellular infrastructure modifications.
Solution Approach 2:
The V2X communication system serves multiple functions: it enables lawful interception for law enforcement, provides real-time location tracking for stolen vehicles, supports hit-and-run investigations, and maintains compatibility with existing cellular infrastructure. The same V2X infrastructure handles both safety communications and tracking requirements.
2Measurement precision
If V2X communication is used for tracking, then location precision is improved, but system complexity increases
Solution Approach 1:
V2X endpoints in vehicles automatically broadcast their locations without requiring manual activation or complex configuration. The vehicles self-manage their tracking participation by continuously transmitting location data through standard V2X protocols, reducing the operational complexity for law enforcement agencies.
Solution Approach 2:
The V2X application server acts as an intermediary that simplifies the complexity by centralizing the collection, filtering, and distribution of location data. It receives broadcasts from numerous vehicles, identifies matches with tracking requests, and delivers relevant information to law enforcement, abstracting away the complexity of individual vehicle communications.
3Area of stationary object
If tracking requests are distributed to all V2X endpoints, then tracking coverage is maximized, but network traffic increases
Solution Approach 1:
The system optimizes network traffic by distributing tracking requests only to V2X endpoints within relevant geographic areas rather than all endpoints globally. The V2X application server determines which endpoints are in proximity to target vehicles and directs tracking requests only to those local endpoints, reducing unnecessary network traffic while maintaining comprehensive coverage.
4Loss of time
If real-time tracking is implemented, then response time for law enforcement is improved, but energy consumption increases
Solution Approach 1:
V2X endpoints broadcast their locations periodically rather than continuously in real-time. This periodic broadcasting approach provides sufficient location updates for law enforcement tracking while significantly reducing energy consumption compared to continuous transmission. The broadcast interval is optimized to balance between response time requirements and energy conservation.
