Navigation Data Update via Charging Station Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems require manual periodic software updates to obtain the latest map data, leading to inefficiencies in time and cost.
Innovation Solution
A method and system for updating navigation data through communication between a charging station and a vehicle, or between vehicles, allowing for automatic updates of map data while the vehicle is charging or driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual periodic software updates are required to obtain the latest map data, then the navigation system can be kept simple, but time and cost are wasted due to manual intervention
Solution Approach 1:
The navigation system automatically detects its own update needs, initiates downloads during charging periods, and installs updates without user intervention. The system serves itself by monitoring map data versions, scheduling updates during idle charging time, and managing the entire update process autonomously.
Solution Approach 2:
The system performs update actions in advance by downloading map data updates during charging periods before they are needed for navigation. This preliminary action ensures that updated map data is ready before the user needs it, eliminating the need for manual updates at the moment of need.
2Productivity
If map data is updated during charging time, then manual updates are eliminated, but the charging time may be extended
Solution Approach 1:
The system performs partial updates by downloading only the necessary map data changes rather than complete datasets. It updates map data incrementally during charging periods, performing just enough action to maintain current navigation functionality without requiring full data replacements.
Solution Approach 2:
The system checks for map data updates periodically and schedules them during charging periods. By spacing out update operations and performing them in periodic intervals during natural charging cycles, the system avoids continuous high-bandwidth downloads that would extend charging time.
3Ease of manufacture
If vehicle-to-vehicle communication is used for map data sharing, then update costs are reduced, but system complexity increases
Solution Approach 1:
The system merges map data update functionality with existing vehicle-to-vehicle communication infrastructure. By combining map data sharing with regular vehicle communication protocols already present in modern vehicles, the system reduces overall complexity rather than adding separate dedicated update communication channels.
Solution Approach 2:
The communication system serves multiple functions: it handles both regular vehicle operational communications and map data update transmissions. This multi-functionality reduces the need for separate dedicated update infrastructure, lowering overall system complexity while enabling cost-effective peer-to-peer data sharing.

AI summary
A method for updating navigation data may be performed by a computing device. The method may include establishing connection between a charging station and a vehicle system; obtaining information of the vehicle system that includes an expected charging time of the vehicle and version information of map data of the vehicle system; determining an updating target range of the map data based on the information of the vehicle system; and updating the map data based on the updating target range of the map data.
