Multi-Vehicle Smart Key with User-Based Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart keys can only control a single vehicle and lack advanced features for user convenience, such as selecting the most suitable vehicle based on user and vehicle information, setting control authorities, and integrating with mobile terminals for remote control.
Innovation Solution
A smart key system that includes a communication unit, information acquisition device, and processor to select and control multiple vehicles, acquire user information, and exchange signals, allowing for features like selecting vehicles based on user preferences, setting control authorities, and remote operation via mobile terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a smart key is designed to control only one vehicle, then the device complexity is low and ease of operation is high, but the adaptability is limited
Solution Approach 1:
The smart key is designed with multi-functionality to control multiple vehicles. The processor stores authentication information for multiple vehicles and can selectively authenticate with different vehicles based on user needs, enabling one smart key to replace multiple vehicle-specific keys
2Adaptability or versatility
If a smart key stores authentication information for multiple vehicles, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The authentication information for multiple vehicles is segmented and stored as separate authentication records in the processor. Each vehicle's authentication information is independently managed, allowing the smart key to selectively activate appropriate authentication credentials without managing complex integrated systems
3Ease of operation
If the smart key can select vehicles based on user information, then user convenience is improved, but the device complexity increases
Solution Approach 1:
The smart key system provides self-service by automatically selecting the appropriate vehicle based on stored user information such as destination, preferred vehicle type, or driving records. The processor autonomously makes selection decisions without requiring complex user input or manual vehicle selection procedures
4Reliability
If control authority is set for different users, then safety is improved, but the device complexity increases
Solution Approach 1:
Different control authorities are assigned to different users based on their specific needs and roles. Each user receives customized authentication credentials with specific permission levels (e.g., full control, limited control, emergency access only), allowing tailored safety measures without requiring a uniform complex authorization system for all users
