Vehicle Routing Augmentation via Multi-Source Map Data Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle routing systems rely on single sources of map data, which may not provide comprehensive information for navigation, such as traffic data, road conditions, and other relevant details.
Innovation Solution
The system integrates data from multiple sources, including different vendors, mapping software, vehicle data, and government-provided information, to augment map and routing data, allowing for comparison and modification of route data to provide more accurate navigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If single source map data is used for vehicle routing, then system complexity is reduced, but navigation information completeness deteriorates
Solution Approach 1:
The patent merges map data from multiple sources (first map data from first source, second map data from second source, and supplemental mapping information) into a single augmented routing system. The control system receives, compares, and integrates data from these multiple sources to provide comprehensive navigation information that includes traffic data, road conditions, and other relevant details that would be unavailable from a single source.
2Loss of information
If multiple sources of map data are integrated, then navigation information completeness is improved, but system complexity increases
Solution Approach 1:
The control system acts as an intermediary that receives map data from multiple sources, compares the data, and integrates it into a unified augmented routing output. This intermediary function manages the complexity of multiple data sources by providing a centralized processing mechanism that handles data reconciliation, comparison, and integration, thereby managing system complexity while achieving information completeness.
3Measurement precision
If data from multiple vendors and sources is combined, then routing accuracy is improved, but data processing complexity increases
Solution Approach 1:
The patent segments the data processing function into distinct stages: receiving first map data from a first source, receiving second map data from a second source, comparing the data from multiple sources, and then integrating the augmented routing information. This segmentation of the processing workflow manages data processing complexity by breaking down the integration task into manageable sequential steps while maintaining routing accuracy through systematic data comparison and synthesis.
Data Source
AI summary
A vehicle includes an output device configured to communicate information to a driver of the vehicle. The vehicle further includes a control system configured to: receive first map data from a first source, the first map data including one or more first routes; supplement the first map data with supplemental mapping information; and display, via the output device, navigation directions according to: (i) the first map data and (ii) the supplemental mapping information. The supplemental data may be second map data from a second source, which may include one or more second routes. If the second routes are found to match the first routes, information, such as ETAs of the one or more second routes, may be used for the supplemental mapping information or to select among multiple first routes.
