Digital Key Name Synchronization for Consistent Vehicle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to synchronize digital key names consistently between terminal devices and vehicle-side devices, leading to inconsistent displays and poor user experience.
Innovation Solution
A method and apparatus for synchronizing digital key names by acquiring and updating the names on both terminal and vehicle-side devices using designated storage areas and preset TLV formats, ensuring timely and accurate synchronization through detection and deletion of fields indicating name changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital key names are updated independently on terminal devices and vehicle-side devices, then each device can maintain its own name changes, but the names become inconsistent between devices
Solution Approach 1:
The patent implements a feedback mechanism where each device monitors for name changes on the other device and automatically synchronizes by updating its own display to match. When a name change is detected through communication between terminal device and vehicle-side device, the detecting device receives the new name and updates its display accordingly, ensuring consistency while allowing independent updates.
2Reliability
If digital key names are synchronized in real-time between terminal devices and vehicle-side devices, then name consistency is maintained, but system complexity increases
Solution Approach 1:
The patent employs a self-service synchronization approach where each device autonomously monitors for name changes, detects them through communication protocols, and automatically updates its own display without requiring complex centralized coordination. The device that detects a name change initiates the synchronization by communicating the new name to the other device, which then updates itself, eliminating the need for complex bidirectional real-time synchronization infrastructure.
3Ease of operation
If digital key names are not synchronized, then device operation is simple, but user experience deteriorates due to inconsistent displays
Solution Approach 1:
The system maintains simplicity by using a lightweight feedback mechanism where devices exchange name change information through existing communication channels. When a name change occurs on either device, the change is communicated to the other device which updates its display accordingly. This feedback-based approach avoids complex synchronization protocols while ensuring both devices display the same digital key name, thereby maintaining good user experience without complicating device operation.
Data Source
AI summary
A method and an apparatus for synchronizing information, and a storage medium. The method includes acquiring, in response to determining that a digital key name has been changed by a vehicle-side device, a first name of a digital key changed by the vehicle-side device; and changing a digital key name displayed on the terminal device to the first name.
