Vehicle Wireless Key Memory Update via Mobile Terminal Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle wireless key systems face challenges in user friendliness and security, particularly when users lose multiple wireless keys, as they require whole system replacement, which is costly and difficult due to secure attachment to prevent theft.
Innovation Solution
Incorporating a wireless key apparatus with a memory updating unit that verifies a mobile terminal against registered terminal identification information, allowing key identification information updates without replacing the entire system, while ensuring secure registration and deletion processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire wireless key system is replaced when keys are lost, then security is maintained, but user friendliness deteriorates and cost increases
Solution Approach 1:
The wireless key system is segmented into two independent components: the wireless key itself and the mobile terminal. The mobile terminal serves as a separate authentication device that can verify and manage wireless keys without requiring replacement of the entire system. This segmentation allows users to lose wireless keys without needing to replace the whole system, thereby improving user friendliness while maintaining security through the mobile terminal's verification capability.
2Reliability
If the entire wireless key system is replaced when keys are lost, then security is maintained, but system complexity and installation difficulty increase
Solution Approach 1:
By dividing the system into independent wireless key and mobile terminal components, the patent enables selective replacement of only the wireless key rather than the entire system. The mobile terminal remains in place and continues to provide authentication services, significantly reducing system replacement complexity and installation difficulty while maintaining security through continued verification functionality.
3Reliability
If mobile terminal verification is implemented for key updates, then security is enhanced, but device complexity increases
Solution Approach 1:
The mobile terminal performs self-verification by checking whether it is in possession of the user before allowing wireless key updates. This self-service mechanism enhances security without requiring complex external verification systems, as the mobile terminal itself serves as the verification authority using its existing identification information, thereby minimizing additional device complexity.

AI summary
A vehicle wireless key apparatus includes a wireless key memory, a terminal information memory, and a memory updating unit. The wireless key memory is provided in a vehicle. Key identification information of a wireless key of the vehicle is to be registered in the wireless key memory. Terminal identification information of a mobile terminal is to be registered in the terminal information memory. The mobile terminal is used separately from the wireless key. The memory updating unit is configured to perform update of the key identification information registered in the wireless key memory. The memory updating unit is configured to verify, upon the update, the mobile terminal against the terminal identification information registered in the terminal information memory.
