Vehicle Gateway Controller Security Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle communication control systems tend to increase in size due to the need for a management server to monitor security, leading to inefficiencies and potential for further improvement.
Innovation Solution
A vehicle communication control system comprising a switching unit with multiple ports, a gateway unit capable of protocol conversion, and a power supply unit, where the gateway unit's controller executes security processing, eliminating the need for a dedicated security processor in the switching unit, thus reducing system size and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a management server is added to monitor security of the switching hub, then security monitoring capability is improved, but system size increases
Solution Approach 1:
The patent merges the security monitoring function into the gateway unit's controller, which already exists in the system. Instead of adding a separate management server, the controller executes security processing to monitor the switching unit, thereby combining multiple functions (protocol conversion and security monitoring) into a single component, reducing system size while maintaining security monitoring capability
Solution Approach 2:
The gateway unit's controller is designed to perform multiple functions: both protocol conversion for communication between different networks and security processing for monitoring the switching unit. This multi-functionality eliminates the need for dedicated separate components, addressing the contradiction by improving security monitoring without increasing system size
2Adaptability or versatility
If protocol conversion functionality is added to enable communication between different networks, then adaptability is improved, but device complexity increases
Solution Approach 1:
The gateway unit's controller is designed to perform multiple functions: both protocol conversion for communication between different networks and security processing for monitoring the switching unit. This multi-functionality eliminates the need for dedicated separate components, addressing the contradiction by improving security monitoring without increasing system size
