Virtual Key Slot Management for Shared Vehicle Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing shared vehicle access lack efficient methods to authenticate and authorize users, leading to difficulties in controlling access privileges and managing vehicle reservations effectively.
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 rights, and if not found, communicate with a reservation management device to obtain or create the necessary access privileges, with features like active and non-active key slots and regular status reporting for key updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If virtual keys are stored locally on the vehicle device for quick access authentication, then access speed and user convenience are improved, but system security and access control precision may deteriorate
Solution Approach 1:
The system divides virtual keys into multiple key slots (active and non-active) on the vehicle device, allowing local quick authentication while maintaining security through structured organization. The segmentation enables the vehicle to store multiple virtual keys locally for fast access determination without compromising security, as each key slot is properly managed and can be updated remotely.
Solution Approach 2:
The vehicle device acts as an intermediary between the central reservation management system and the access control mechanism. It stores virtual keys locally for rapid authentication decisions while maintaining communication with the central system to update keys and synchronize access privileges, thus balancing speed and security.
2Adaptability or versatility
If multiple virtual keys are stored on the vehicle device to support multiple users, then user versatility and access flexibility are improved, but device complexity and storage requirements increase
Solution Approach 1:
The system segments virtual keys into organized key slots on the vehicle device, with designated active and non-active slots. This structured segmentation allows multiple users to be supported while maintaining manageable complexity through systematic organization and clear key slot management protocols.
Solution Approach 2:
The vehicle device is designed with universal key slot functionality that can store and manage multiple different virtual keys for different users. Each key slot can hold a virtual key associated with different user credentials and access privileges, making the device adaptable to various authentication scenarios without requiring separate hardware for each user.
3Measurement precision
If the vehicle device communicates with the reservation management device for every unknown credential, then access control accuracy is improved, but communication overhead and system response time increase
Solution Approach 1:
The system performs preliminary actions by pre-storing multiple virtual keys and their associated user credentials in the vehicle device's key slots before authentication is needed. When a user attempts access, the vehicle can quickly check local key slots first, only communicating with the reservation management device when necessary, thus reducing communication overhead while maintaining accurate access control.
Solution Approach 2:
The vehicle device performs self-service authentication by independently checking credentials against stored virtual keys in its key slots without requiring external system communication for every access attempt. This self-service capability reduces communication overhead and improves response time while maintaining accurate access control for recognized credentials.

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.
