Host Vehicle Projected Transportation Network Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle transportation network information is often missing, incomplete, or inaccurate, which hinders effective navigation and routing in vehicle transportation systems.
Innovation Solution
A method and apparatus for generating projected vehicle transportation network information by a host vehicle, using received remote vehicle messages containing geospatial and kinematic state information from other vehicles to create a projected representation of the network, allowing the host vehicle to traverse and navigate through the network even in areas with unavailable or incomplete information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vehicle transportation network information is used for navigation, then routing capability is enabled, but the information may be missing, incomplete, or inaccurate
Solution Approach 1:
The system implements feedback by continuously receiving messages from multiple remote vehicles containing their geospatial and kinematic state information. This feedback loop allows the host vehicle to continuously update and refine its projected transportation network information, improving accuracy and completeness dynamically as vehicles traverse the network
Solution Approach 2:
The system merges data from multiple remote vehicles by aggregating their geospatial state information (positions, headings) and kinematic state information (velocities, accelerations). This combination of multiple data sources creates a more complete and accurate projected transportation network representation than any single vehicle could provide alone
2Reliability
If projected vehicle transportation network information is generated using remote vehicle messages, then navigation reliability is improved, but computational complexity increases
Solution Approach 1:
Each vehicle autonomously generates its own projected transportation network information by processing received messages from other vehicles. This self-service approach distributes the computational burden across multiple vehicles rather than requiring a centralized processing system, reducing overall system complexity while maintaining high reliability
Solution Approach 2:
The system performs preliminary actions by pre-calculating projected transportation network information based on current remote vehicle messages before navigation is needed. This allows the host vehicle to have reliable navigation data ready in advance, reducing real-time computational requirements during actual navigation
