Map Data Storage Format Conversion for Vehicle Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing map data storage methods are limited to specific formats, preventing the editing of map data content in different formats within a subject vehicle's system.
Innovation Solution
Converting acquired map data content into a predetermined format compatible with the subject vehicle's system, storing it in a common database, and editing it based on update information to ensure compatibility and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If map data content in a specific format is stored, then the map data can be used in the subject vehicle, but map data content in different formats cannot be edited
Solution Approach 1:
The patent introduces a format conversion unit as an intermediary component that converts map data from various external formats into the predetermined format required by the subject vehicle's system. This mediator enables compatibility with different source formats without requiring changes to the core system, resolving the contradiction between adaptability and complexity by isolating format handling in a dedicated conversion layer
2Adaptability or versatility
If map data in different formats is acquired from external sources, then more data sources can be utilized, but the data cannot be integrated into the subject vehicle's system
Solution Approach 1:
The patent applies parameter changes by systematically transforming the format parameters of acquired map data into the predetermined format structure. The format conversion unit modifies data structure parameters, encoding parameters, and organization parameters to match the subject vehicle's requirements, enabling seamless integration of externally sourced data while maintaining ease of operation through automated parameter transformation
