Vehicle Database Incremental Update via Remote Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for updating remotely-stored databases across multiple vehicles are costly and time-consuming, as they require sending maintenance individuals to physically connect and update each vehicle, incurring high labor and communication fees, especially when updating an entire fleet.
Innovation Solution
A method that determines the installed version of a remote database, identifies incremental updates to reach a desired version, and provides these updates directly to the vehicle computer via a communication network, eliminating the need for physical human intervention by using incremental update information that includes integrity checks for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If maintenance individuals physically connect to each vehicle to update databases, then update accuracy is ensured, but labor costs and time consumption increase significantly
Solution Approach 1:
The vehicle computer autonomously performs database update operations by receiving update packages, determining installed versions, applying incremental updates, and verifying integrity checks without requiring physical presence of maintenance personnel at each vehicle location
Solution Approach 2:
The patent replaces the mechanical process of physical connection and manual update execution with an automated electronic communication system that transmits update packages and executes updates remotely through the vehicle computer's processing capabilities
2Reliability
If maintenance individuals visit each remote vehicle for database updates, then updates can be verified manually, but communication fees and labor costs increase
Solution Approach 1:
The vehicle computer automatically performs integrity checks on received update packages and verifies successful application of incremental updates, then transmits verification results back to the remote server, eliminating the need for manual verification while reducing communication costs through automated feedback loops
3Reliability
If full database versions are transmitted to each vehicle, then complete updates are ensured, but data transmission volume and communication fees increase
Solution Approach 1:
The patent divides the database update process into segments by transmitting only the differential portions (incremental updates) rather than complete database versions, reducing data transmission volume while maintaining update completeness through structured update packages containing version information and integrity checks
Solution Approach 2:
The system extracts and transmits only the necessary update components (incremental changes) from the full database, separating the essential update data from the complete dataset to minimize transmission requirements while ensuring complete updates are applied
4Productivity
If automated remote updates are implemented, then labor costs and time are reduced, but system complexity increases
Solution Approach 1:
The vehicle computer performs multiple functions including receiving update packages, determining installed versions, applying incremental updates, executing integrity checks, and transmitting verification results, consolidating these capabilities into an existing multi-functional system rather than adding dedicated specialized hardware

AI summary
Systems and methods for updating remote databases are provided. In certain embodiments, a method includes determining an installed version for a remote database stored on a vehicle computer. Further, the method includes identifying an incremental update for the remote database, wherein the incremental update contains differences between a desired version for the remote database and the installed version. Additionally, the method includes providing the incremental update to the vehicle computer. Also, the method includes updating the remote database with the incremental update.
