Shared Vehicle Virtual Keys for Real-Time Access Privileges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing shared vehicle access lack efficient methods for assigning and managing vehicle access privileges, leading to difficulties in providing or denying access to users in a secure and efficient manner.
Innovation Solution
A method and system that utilize virtual keys stored on a vehicle device, associated with specific user lists and access privileges, where credentials are used to determine access, with communication with a reservation management device for privilege verification and updates, enabling secure and dynamic access control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional access control methods are used for shared vehicles, then system simplicity is maintained, but access management efficiency and security are insufficient
Solution Approach 1:
The access control system is segmented into multiple components: virtual keys stored in the vehicle device, user credentials stored in user devices, and a reservation management device for coordination. This segmentation allows each component to have a specific function, improving security while keeping individual components simple.
Solution Approach 2:
The reservation management device acts as an intermediary between user devices and vehicle devices. It receives credentials from user devices, determines access rights, and communicates with vehicle devices to grant or deny access. This intermediary layer enhances security without requiring complex logic in the vehicle device itself.
2Measurement precision
If real-time access privilege determination is implemented, then access control accuracy is improved, but processing time increases
Solution Approach 1:
User credentials and vehicle access information are pre-stored in respective devices before access is needed. When a user attempts to access a vehicle, the system performs a straightforward comparison of pre-stored data rather than performing complex real-time calculations, thus maintaining accuracy while minimizing processing time.
Solution Approach 2:
The system uses credential copying and matching between devices. User credentials are copied to user devices during registration, and vehicle access information is copied to vehicle devices. Access determination involves comparing these copied credentials, which is a fast operation that maintains precision without significant time loss.
3Adaptability or versatility
If multiple user lists and virtual keys are stored in the vehicle device, then access management versatility is improved, but storage requirements increase
Solution Approach 1:
The vehicle device is designed with universal functionality to store and process multiple virtual keys and user lists. This multi-functionality allows the same device structure to handle various access scenarios (different users, different vehicles, different access rights) without requiring separate hardware for each case, thus improving versatility while controlling storage requirements.
Data Source
AI summary
The present systems, devices, and methods relate to managing shared vehicle access. Vehicle access can be provided to a candidate user based on whether the user is included in a list of at least one user associated with a respective virtual key. Virtual keys can be created, or lists of at least one user can be updated to include the candidate user, to in turn provide vehicle access. Virtual keys can be stored in a plurality of virtual key slots, with vehicle access being provided based on a virtual key stored in an active key slot. Status reports can be sent to a reservation management device, for updating virtual keys or lists of at least one user.
