Vehicle Transmission Unlock Control Using User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicles are vulnerable to theft when left unattended in parking or chauffeur service situations, as existing transmission control systems lack user authentication, allowing unauthorized individuals to drive or steal the vehicle.
Innovation Solution
A device and method that utilize user authentication, including face, iris, or fingerprint recognition, to lock and unlock the vehicle's transmission based on the user's presence or departure, preventing unauthorized access and enhancing security through a controller integrated with key detection and authentication systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transmission is left unlocked for ease of operation in valet parking or chauffeur service situations, then the ease of operation is improved, but the vehicle becomes vulnerable to theft
Solution Approach 1:
The system dynamically changes the transmission lock state parameter based on detected situations. When valet parking or chauffeur service is detected, the transmission remains unlocked. When other situations are detected, the transmission is locked. This allows the same system to adapt to different operational contexts, providing ease of operation when needed while preventing theft when not needed.
Solution Approach 2:
The system continuously monitors various sensors (door sensors, ignition status, gear position) to detect the current situation and provides feedback to the controller. Based on this feedback, the controller automatically adjusts the transmission lock state. This closed-loop feedback mechanism ensures the transmission accessibility responds appropriately to changing conditions, maintaining ease of operation during authorized use while preventing unauthorized access.
2Object-affected harmful factors
If user authentication is implemented to prevent theft, then the security is improved, but the device complexity increases
Solution Approach 1:
The authentication requirement is dynamic rather than static. The system automatically adjusts whether authentication is needed based on the detected situation. In valet parking or chauffeur service situations, authentication is not required and the transmission remains accessible. In other situations, authentication is required. This dynamic approach provides strong security when needed while avoiding unnecessary complexity and user burden when not needed.
Solution Approach 2:
The system uses existing vehicle sensors and controllers (door sensors, ignition system, gear position sensors) to automatically detect the situation and determine whether authentication should be required. This self-service approach eliminates the need for separate complex authentication detection systems, reducing overall device complexity while maintaining security.
3Object-affected harmful factors
If the transmission is locked to enhance security, then the security is improved, but the ease of operation deteriorates
Solution Approach 1:
The system dynamically changes the transmission lock state parameter based on detected situations. When valet parking or chauffeur service is detected, the transmission remains unlocked. When other situations are detected, the transmission is locked. This allows the same system to adapt to different operational contexts, providing ease of operation when needed while preventing theft when not needed.
Solution Approach 2:
The authentication requirement is dynamic rather than static. The system automatically adjusts whether authentication is needed based on the detected situation. In valet parking or chauffeur service situations, authentication is not required and the transmission remains accessible. In other situations, authentication is required. This dynamic approach provides strong security when needed while avoiding unnecessary complexity and user burden when not needed.
