Vehicle Computing System POI Data Update via Nomadic Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation systems face reduced utility due to outdated point-of-interest (POI) data, which is not efficiently updated, affecting the accuracy and relevance of route information.
Innovation Solution
A vehicle computing system (VCS) integrates with a nomadic device to connect over local and wide-area connections, allowing it to receive and provide updated POI data from a location service, enabling the navigation application to access and utilize the most current POI information based on vehicle location and category.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If POI data is stored locally in the navigation system database, then the system can provide offline navigation functionality, but the POI data becomes outdated over time, reducing system utility
Solution Approach 1:
The patent introduces a nomadic device (mobile device) as an intermediary between the navigation system and the location service. The mobile device retrieves current POI data from the location service over wide-area connections and transfers it to the vehicle computing system via local connections, serving as a mediator that bridges the offline navigation database and the online location service to maintain data currency without compromising offline functionality
Solution Approach 2:
The patent adds a new dimension to the navigation system architecture by introducing a dual connection system: local connections for offline database access and wide-area connections for online data updates. This dimensional expansion allows the system to simultaneously maintain offline navigation capability while periodically refreshing POI data through the nomadic device's wide-area network connection
2Reliability
If the navigation system continuously updates POI data, then the data remains current and useful, but the system complexity and resource consumption increase
Solution Approach 1:
The nomadic device performs POI data updates autonomously by automatically connecting to the location service, retrieving current POI data, and transferring it to the vehicle computing system without requiring manual user intervention. This self-service mechanism maintains POI data currency while simplifying the overall system operation, as the update process occurs automatically in the background
3Adaptability or versatility
If the navigation system uses offline database only, then the system operates independently without external connections, but the POI search functionality becomes less effective due to outdated information
Solution Approach 1:
The patent implements a dynamic POI data update mechanism where the navigation system transitions between offline and online modes. The system maintains its core offline independence but dynamically connects to the location service through the nomadic device when update opportunities arise, allowing it to adapt between autonomous operation and data refresh states to maintain both independence and effectiveness

AI summary
A nomadic device may be configured to connect to a vehicle computing system (VCS) over a local connection and to a location service over a wide-area connection, receive point-of-interest data over the wide-area connection from the location service, and provide the point-of-interest data to the VCS over the local connection for use by a navigation application of the VCS. The VCS may be configured to connect over a local connection to a nomadic device configured to execute a location application to connect to a location service over a wide-area connection, receive user interface input requesting point-of-interest data for use by a navigation application of the VCS, and responsive to the input, send a command over the local connection to request the point-of-interest data from the location application.
