Vehicle Component Control via Service Controller Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems lack secure control mechanisms to manage vehicle components for specific tasks performed by multiple users, requiring a solution to authenticate and authorize users for different operation modes.
Innovation Solution
A system that includes a service controller connected to a vehicle, which authenticates users and sets operating limits for vehicle components based on specified operation modes, allowing authorized users to perform specific tasks while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle components are controlled for multiple users to perform different tasks, then the vehicle system becomes more versatile and adaptable, but the control security and access management become more complex
Solution Approach 1:
The control system is segmented into different operation modes (normal mode, service mode, development mode) with distinct access levels. Each mode has specific authorized users and permitted operations, allowing multiple users to access vehicle components for different tasks while maintaining security through mode-based segmentation rather than a single complex access control system
Solution Approach 2:
A service controller acts as an intermediary between users and vehicle components. The service controller receives authentication data, determines the appropriate operation mode, and mediates access to components accordingly. This intermediary simplifies the overall control security mechanism by centralizing authentication and mode management in a single component rather than requiring complex distributed access control
2Reliability
If authentication and operation mode setting are required for each user, then access security is improved, but the time required for user verification and setup increases
Solution Approach 1:
The service controller is pre-configured with authentication data and operation mode definitions before actual use. When a user connects the service controller to the vehicle, the authentication and mode selection process is already prepared and can be executed quickly through simple user input, rather than requiring lengthy verification procedures at the moment of access
3Reliability
If operating limits are enforced for different operation modes, then safety is improved, but the flexibility of component operation is reduced
Solution Approach 1:
The operating limits are dynamic and change based on the selected operation mode. The system allows different flexibility levels for different modes: normal mode has standard limits for everyday use, service mode has expanded limits for maintenance tasks, and development mode has maximum flexibility for testing. This dynamic adjustment maintains safety by enforcing appropriate limits for each context while preserving operational flexibility when needed
Data Source
AI summary
A system includes a computer including a processor and a memory, the memory including instructions executable by the processor to detect a service controller connected to a vehicle, upon authenticating the service controller, receive an operation mode for a vehicle component from the service controller, and actuate the vehicle component within operating limits based on the operation mode.
