Vehicle Access Control Using Multi-Level User Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle systems lack the functionality to grant different levels of access to vehicle functionalities to various users, preventing non-owners from accessing specific vehicle features upon correct identification and authentication.
Innovation Solution
A device and method that utilize a vehicle's onboard processor to receive identification data from external devices, compare it with stored user identifications, and grant access to specific vehicle functionalities based on matching identities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional vehicle systems enable users to sync and pair mobile devices for basic access, then basic infotainment functionality is achieved, but the system cannot grant different levels of access to different users
Solution Approach 1:
The patent segments vehicle access into multiple distinct levels (first level, second level, third level) with different functionality sets. Each user identification is associated with a specific access level, allowing the system to provide differentiated access without requiring a completely new system architecture. The processor segments user identifications into categories (owner, household member, other) and grants相应 access levels based on matching.
Solution Approach 2:
The existing vehicle processor and identification system are made multi-functional by enabling them to handle multiple access levels and user types. The same processor that previously handled basic infotainment pairing now also performs multi-level authentication and access control, eliminating the need for separate hardware systems while providing enhanced functionality.
2Ease of operation
If the vehicle system grants access to multiple user identifications with different functionality sets, then user-specific access control is achieved, but the system requires storing and comparing multiple user identifications
Solution Approach 1:
The system performs preliminary actions by pre-storing multiple user identifications and their associated access levels in the vehicle's memory before authentication occurs. When a user attempts to access the vehicle, the processor retrieves and compares the presented identification against the pre-stored identifications, enabling quick authentication without real-time complex calculations or external verification.
3Adaptability or versatility
If conventional systems allow paired device access, then basic connectivity is provided, but non-owners cannot access specific vehicle features even with correct identification
Solution Approach 1:
The patent applies local quality by assigning different functionality sets to different user identifications. The owner identification grants full access to all vehicle features, while household member and other user identifications grant access only to specific subsets of features. This localized access control ensures that each user type receives appropriate access rights based on their relationship to the vehicle, maintaining security while enabling broader user type coverage.
Data Source
AI summary
A method for granting access to vehicle functionalities is provided. The method includes receiving a signal from a device that is external to the vehicle, the signal including identification data of an object associated with the device, comparing the identification data with user identifications stored in the memory of the vehicle, and granting, to the object, access to a first set of functionalities of the vehicle in response to determining that the identification data matches a first user identification of the user identifications stored in the memory of the vehicle.
