Vehicle Software Update Data Management Without Real-Time Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for manually updating onboard device software in vehicles fail to reflect the update status in the individual-vehicle-information database, requiring users to visit a dealer store for manual updates due to lack of real-time communication.
Innovation Solution
A data management apparatus and program that generate and manage update data with appended update keys, enabling the update status to be reflected in the database by using a storage medium to transfer data between the onboard device and the apparatus, even without direct communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If real-time communication is established between the individual-vehicle-information database and the onboard device, then the update status can be reflected in the database automatically, but the system complexity and communication infrastructure requirements increase
Solution Approach 1:
The patent introduces a storage medium (USB drive, memory card, etc.) as an intermediary carrier that bridges the gap between the onboard device and the individual-vehicle-information database. When the user manually updates software via a personal computer, the update status information is written to the storage medium, which is then read by the onboard device and transmitted to the database, enabling automatic reflection without direct real-time communication infrastructure.
Solution Approach 2:
The system enables the onboard device to autonomously capture its own update status information and independently transmit it to the individual-vehicle-information database through the storage medium, without requiring continuous external communication support or dealer intervention.
2Ease of operation
If the user manually updates software via personal computer without real-time communication, then the update process is simple and user-friendly, but the update status cannot be reflected in the individual-vehicle-information database
Solution Approach 1:
The storage medium serves as an intermediary that carries update status information from the onboard device to the individual-vehicle-information database. The personal computer reads the update status from the onboard device via the storage medium and transmits it to the database, ensuring no information loss while maintaining manual update simplicity.
Solution Approach 2:
The system establishes a feedback loop where the onboard device's update status is captured, processed through the storage medium, and fed back to the individual-vehicle-information database, ensuring the database always reflects the current update state even in manual update scenarios.
3Reliability
If the user visits the dealer store to report completion of manual update, then the update status can be reflected in the database, but the user convenience and time efficiency decrease
Solution Approach 1:
The onboard device autonomously captures its update status information and independently transmits it to the individual-vehicle-information database through the storage medium, eliminating the need for users to visit dealer stores for status reporting while ensuring reliable database reflection.
Solution Approach 2:
The storage medium acts as an intermediary that enables automatic status transmission from the onboard device to the database, replacing the manual dealer visit process and saving user time while maintaining reliable information reflection.
