Vehicle Control Fallback for Offline Fee-Based Functions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle systems face challenges in authenticating fee-based functions when network connectivity is lost, leading to potential disruptions and user anxiety during travel in areas with poor radio wave reception.
Innovation Solution
A vehicle control system that includes a network communication unit, authentication unit, and search unit, enabling the execution of alternative functions when network authentication fails, ensuring continued functionality for essential services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle system continuously checks network authentication status, then service security is improved, but energy consumption increases
Solution Approach 1:
Instead of continuously checking authentication status, the system implements periodic authentication checks that are triggered by specific events such as network connectivity changes, function activation requests, or time-based intervals. This periodic approach maintains authentication accuracy while significantly reducing energy consumption compared to continuous verification.
2Adaptability or versatility
If the vehicle system stores detailed authentication information locally, then offline functionality is improved, but data security risks increase
Solution Approach 1:
The system applies different quality levels to different parts of stored authentication data. Sensitive authentication credentials are stored in encrypted form with restricted access, while less sensitive function availability information is stored in plain text for quick retrieval. This local quality differentiation enables offline functionality while minimizing data security risks by only encrypting the most critical information.
Data Source
AI summary
A vehicle control system equipped to a vehicle includes at least one of (i) a circuit and (ii) a processor with a memory storing computer program code executable by the processor. The at least one of the circuit and the processor configured to cause the vehicle control system to: communicate with a server via a network, the server storing information about a fee-based function that can be executed by an occupant of the vehicle; authenticate whether the fee-based function can be executed by performing a communication with the server; search for an alternative function having same purpose of use as the fee-based function; and execute the alternative function in response to determining that the fee-based function cannot be executed.
