Vehicle Digital Key Logging via Server-Mediated Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital key registration processes may fail to complete successfully due to inconsistent specifications between digital key service providers and operating system providers, leading to incomplete or missing log information necessary for diagnosing registration issues.
Innovation Solution
A vehicle system that includes a processor to transmit log information of digital key events to a management server, ensuring comprehensive logging of registration and deletion processes, regardless of the application used on the mobile information terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a third-party OS provider develops the digital key registration application, then the application can be widely compatible with different mobile information terminals, but the log information necessary for diagnosing registration issues may not be uploaded to the management server
Solution Approach 1:
The vehicle acts as an intermediary between the mobile information terminal and the management server. It receives log information from the mobile terminal during digital key registration and forwards it to the management server, ensuring that diagnostic log data is transmitted even when using third-party registration applications that may not directly support log upload functionality.
2Loss of information
If the registration application is developed by the digital key service provider, then the log information specifications can be precisely controlled, but the application may not be compatible with all mobile information terminals and operating systems
Solution Approach 1:
The system divides the log information transmission function into separate components: the mobile terminal generates logs, the vehicle collects and manages them, and the management server receives and processes them. This segmentation allows the vehicle to handle log transmission independently of which application is used on the mobile terminal, improving both compatibility and log information reliability.
3Productivity
If digital key registration processing is attempted without proper log management, then the registration process can proceed quickly, but the cause of registration failures cannot be identified
Solution Approach 1:
The system implements feedback by collecting log information from the mobile terminal during registration, transmitting it through the vehicle to the management server. This feedback loop provides diagnostic information about registration successes and failures without significantly impacting the registration processing speed, as the log collection occurs concurrently with the registration process.
Data Source
AI summary
A vehicle configured to utilize a digital key registered in a mobile information terminal of a user, in which the vehicle includes a processor configured to transmit, to a management server for the digital key, log information of an event occurring in the vehicle when registering the digital key to the mobile information terminal.
