Vehicle Digital Key Profile Switching via Shared Key Slot IDs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems do not allow for seamless linking of profiles to multiple devices, and there is a need for automatic profile switching when a digital key is shared with new devices.
Innovation Solution
A method and apparatus that enable a vehicle to register a device with a shared digital key and automatically link the corresponding profile, allowing profile selection based on matching slot IDs between the shared key and the vehicle's stored digital key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a profile is linked to only one digital key device, then the system complexity is reduced, but the adaptability and user convenience deteriorate when users need to use multiple devices
Solution Approach 1:
The patent implements a many-to-many mapping relationship between profiles and digital key devices through slot IDs. A single profile can be associated with multiple devices, and each device can access multiple profiles, enabling universal access without increasing fundamental system complexity.
Solution Approach 2:
The patent introduces slot IDs as intermediary identifiers that mediate between profiles and digital key devices. This intermediary layer enables automatic profile selection and linking without requiring complex direct associations between profiles and multiple devices.
2Ease of operation
If manual profile selection is required on the AVN screen, then the system operates reliably with clear user control, but the ease of operation deteriorates when users need to switch between multiple devices
Solution Approach 1:
The patent performs preliminary actions by automatically selecting and linking profiles to digital key devices before the user needs to use them. When a digital key is presented, the corresponding profile is automatically selected based on slot ID matching, eliminating the need for manual selection at the moment of use.
Solution Approach 2:
The system performs self-service by automatically matching profiles to digital key devices through slot ID comparison. The vehicle controller autonomously determines which profile to activate without requiring user intervention on the AVN screen, thereby saving time and improving ease of operation.
3Adaptability or versatility
If digital keys are shared with multiple devices, then the adaptability improves, but the difficulty of detecting and measuring the correct profile association increases
Solution Approach 1:
The patent uses slot IDs as changeable parameters that uniquely identify profile-device associations. By comparing slot IDs between the presented digital key and stored profiles, the system can accurately detect and measure which profile corresponds to which device, even when multiple devices are involved.

AI summary
A method of providing a digital key service, in the vehicle for which the digital key service is provided through the management server for digital keys that issues and manages digital keys and shared keys when a request for issuance of the digital keys and the shared keys is transmitted through a user interface, can include registering a first profile at a user's request, receiving a first digital key including a first slot ID from the management server for digital keys and, linking the first profile to the first slot ID, receiving the shared key, and selecting a profile based on the result of comparing a second slot ID in the shared key and the first slot ID.
