Vehicle Unlocking Device Using Terminal Identification and Local Image Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing keyless entry systems for vehicles are impractical for delivery services as they require pre-registration of authentication images for multiple individuals and fail to function in areas with impaired communication, such as underground parking lots.
Innovation Solution
A vehicle unlocking device that receives identification information from a terminal and captures an image of the person using the terminal, unlocking the vehicle only if the information matches the vehicle and the image is acquired, thereby eliminating the need for pre-registration of individuals and functioning in areas with limited communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication images are pre-registered for multiple individuals in the vehicle system, then unauthorized unlocking can be suppressed, but the device complexity and data storage requirements increase significantly
Solution Approach 1:
The patent introduces a server as an intermediary between the vehicle and authentication image storage. The server stores authentication images and communicates with the vehicle's imaging section, allowing the vehicle to perform authentication without storing large amounts of authentication image data locally. This reduces the vehicle's device complexity while maintaining unauthorized unlocking suppression capability.
Solution Approach 2:
The patent uses the imaging section to capture a copy of the current user's image and compares it with the authentication image stored on the server. This copying approach allows authentication without storing multiple authentication images in the vehicle, reducing storage requirements while maintaining security.
2Reliability
If authentication images are acquired via communication methods, then unauthorized unlocking can be suppressed, but the system fails to function in locations with impaired communication
Solution Approach 1:
The patent performs authentication image capture and comparison operations locally using the imaging section and processing unit, without requiring real-time communication with the server. The server is only needed for initial authentication image storage, allowing the system to function independently in communication-impaired areas while still suppressing unauthorized unlocking.
3Measurement precision
If individual authentication images are stored for each user, then identification accuracy improves, but the loss of time for image management and processing increases
Solution Approach 1:
The patent extracts the authentication image storage function from the vehicle system and places it on the server. The vehicle only needs to perform image capture and comparison operations, significantly reducing the time and complexity of authentication image management while maintaining identification accuracy through server-side storage and management.
Data Source
AI summary
A vehicle unlocking device, including: a memory; a processor connected to the memory; and a reception section configured to receive identification information assigned to respective vehicles, from a terminal carried by a person present at a periphery of a specific vehicle that is one of the respective vehicles, the processor being configured to: acquire an image captured by an imaging section provided at the specific vehicle, and unlock a lock unit of the specific vehicle in a case in which the identification information that has been received is identification information corresponding to the specific vehicle and an image of the person has been acquired.
