Vehicle Access Control System with Granular User Permissions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle access systems lack the ability to restrict access to vehicle systems based on user identity and authority levels, allowing unauthorized access to sensitive controls and security systems.
Innovation Solution
A vehicle access control system that includes a processor, non-volatile memory, and user-specific identification inputs to manage access to activation, control, communication, and computer systems based on user profiles and permissions, using devices like keypads, RFID readers, or biometric scanners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a key holder has access to all control systems and security systems of the vehicle, then ease of operation is improved, but security and access control deteriorate
Solution Approach 1:
The system segments access rights by creating user profiles with different permission levels. Each user profile defines specific access rights to different vehicle systems, dividing the monolithic key holder access into granular, controlled segments. This allows the system to maintain ease of operation through automatic authentication while improving security by restricting access to only authorized systems for each user.
Solution Approach 2:
The system implements local quality by assigning different access permissions to different vehicle systems based on user identity. Instead of uniform access across all systems, each user receives tailored access rights appropriate to their role (e.g., pilot vs. maintenance personnel). This enables the system to provide convenient access where needed while maintaining security restrictions where required.
2Reliability
If access to vehicle systems is restricted based on user identity and authority levels, then security is improved, but device complexity increases
Solution Approach 1:
The access control system serves multiple functions within a single integrated framework: authentication, authorization, logging, and system management. By making the access control device universal, the system improves security across all vehicle systems without requiring separate complex control mechanisms for each system, thereby managing complexity through consolidation rather than multiplication of components.
Solution Approach 2:
The system automatically authenticates users and grants appropriate access rights without requiring manual intervention or complex configuration during operation. User profiles are pre-configured with permission levels, and the system self-manages access decisions based on user identification, reducing operational complexity while maintaining security.
3Measurement precision
If user profiles with system permissions are stored and processed, then access control precision is improved, but information processing requirements increase
Solution Approach 1:
User profiles with detailed permission sets are pre-configured and stored in the system before operation. This preliminary action allows the system to quickly retrieve and apply appropriate access rights during authentication without performing complex real-time analysis, thereby achieving precise access control while minimizing energy consumption during actual access decisions.
Data Source
AI summary
A vehicle access and control system includes an activation system, a vehicle control system, a communication system provided in the vehicle, a computer system mounted in the vehicle, and a vehicle access control system including a processor, a non-volatile memory, and a set of instructions stored on the non-volatile memory. The set of instructions, when executed by the processor, causing the processor to receive a user specific identification input, access a user profile associated with the user specific identification input, determine, from the user profile, system permissions associated with the user specific identification input, and manage access to one or more of the activation system, vehicle control system, communication system, and the computer system based on the system permissions.
