Vehicle Authentication Message Control for Digital Key Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems output unnecessary warning messages when a digital key or fingerprint is used for authentication, even if other authentication devices are present, causing user inconvenience.
Innovation Solution
An apparatus and method that includes a communication device and processor to search for authentication devices within the vehicle, preventing warning messages when at least one device is found and providing guide messages based on the registered authentication device when none are found, using communication protocols like NFC, BLE, or UWB.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a warning message is always output when a door is opened or closed after authentication, then authentication security is maintained, but user convenience deteriorates due to unnecessary warnings
Solution Approach 1:
The system applies different warning output rules based on the specific authentication method used. When digital key authentication is successful, no warning is output for door operations. When smart key authentication is used without digital key registration, warnings are output. This localized differentiation resolves the contradiction by tailoring the warning behavior to the specific authentication context.
Solution Approach 2:
The warning message output is made dynamic based on the authentication state. The system continuously monitors whether digital key authentication was successful and adjusts the warning behavior accordingly. This dynamic adjustment allows the system to maintain security when needed while eliminating unnecessary warnings when digital key authentication is present.
2Loss of information
If a warning message is output based only on the door controlling device, then the authentication requirement is clear, but user experience deteriorates when other authentication devices are present in the vehicle
Solution Approach 1:
The system checks for the presence of multiple authentication devices (smart key, digital key, fingerprint sensor) and determines warning output based on the combination of devices present. When a digital key is successfully authenticated, it universally prevents warnings regardless of which specific door controlling device is used, providing a unified user experience across different authentication methods.
Solution Approach 2:
The system provides feedback to the user through selective warning messages based on the authentication devices detected. When digital key authentication is successful, the system feedback indicates no warning is needed. When only smart key authentication is used without digital key registration, the system feedback includes a warning message. This feedback mechanism resolves the contradiction by providing clear information about authentication status while improving user experience.
3Measurement precision
If the system searches for all authentication devices when door state changes, then accurate authentication device recognition is achieved, but system complexity increases
Solution Approach 1:
The system performs preliminary authentication by checking whether digital key authentication was successful before door operations. This preliminary check determines the warning output behavior without requiring a full search for all authentication devices at the moment of door operation. The system prepares the authentication state in advance, reducing the complexity of real-time device detection while maintaining recognition accuracy.

AI summary
An apparatus for controlling a vehicle includes a communication device that communicates with an authentication device of the vehicle, and a processor that searches for the authentication device inside the vehicle and prevents a guide message for authentication from being output when at least one authentication device found inside the vehicle.
