Valet Key Automatic Communication Subject Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In car sharing services, users hesitate to hand their mobile terminals to third parties for valet parking due to inconvenience when the valet key is not pre-registered, requiring additional operations to enable key information registration.
Innovation Solution
A valet key system with a state determination unit and communication subject setting unit that automatically determines and sets the communication subject based on whether the valet key is operable as a vehicle key, allowing it to function as a vehicle key when lending to a third person, eliminating the need for separate key information registration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If key information is not registered to the valet key, then the valet key cannot be used as the vehicle key, but requiring key information registration operations increases complexity and inconvenience
Solution Approach 1:
The system performs preliminary action by automatically determining the communication subject and registering key information to the valet key before the user needs to use it. The state determination unit checks whether key information is already registered, and the communication subject setting unit automatically establishes communication with the mobile terminal to complete registration, eliminating the need for manual registration operations.
2Ease of operation
If the valet key automatically determines communication subject, then convenience is enhanced and additional operations are reduced, but system complexity increases
Solution Approach 1:
The valet key system performs self-service by automatically determining its own communication subject without user intervention. The state determination unit autonomously checks the registration status of key information, and the communication subject setting unit automatically selects and establishes communication with the appropriate device (mobile terminal or vehicle), making the system intelligent and self-configuring.
3Ease of operation
If users hand over mobile terminals for valet parking, then key information can be directly accessed, but users lose control and security of their personal devices
Solution Approach 1:
The system segments the key access function from the mobile terminal by enabling the valet key to independently store and use key information. Instead of requiring the mobile terminal to be present for valet access, the key information is separately registered to the valet key device, allowing the user to retain possession of their mobile terminal while still enabling valet parking functionality.

AI summary
A valet key operable as a vehicle key when lending a vehicle to a third person includes a state determination unit configured to determine whether or not the valet key is operable as the vehicle key when the valet key transmits a radio wave. The valet key further includes a communication subject setting unit configured to set a communication subject to which the valet key transmits the radio wave based on the determination result of the state determination unit.
