Layered Vehicle Control Restart for Targeted Defect Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle devices require a full system restart when a defect occurs, affecting other normally operating functions, as they lack targeted defect monitoring and resolution capabilities across multiple layers.
Innovation Solution
A vehicle device with a control unit and multiple monitoring units that monitor and resolve defects at specific layers, including a first monitoring unit for the control unit, a second monitoring unit for operating systems, and a third monitoring unit for application programs, allowing for targeted restarts to minimize impact on other functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full system restart is performed when a defect occurs, then the defect is resolved, but other normally operating functions are affected
Solution Approach 1:
The system is divided into multiple independent layers (control unit layer, operating system layer, application program layer), each with its own monitoring unit. When a defect occurs in one layer, only that specific layer is restarted rather than the entire system, allowing other layers to continue operating normally.
2Reliability
If multiple monitoring units are introduced to monitor different layers, then targeted defect resolution is enabled, but device complexity increases
Solution Approach 1:
The monitoring function is segmented into three independent monitoring units, each responsible for a specific layer. This segmentation allows each monitoring unit to independently detect and resolve defects in its designated layer without interfering with other layers, achieving targeted defect resolution while maintaining manageable complexity through clear functional separation.
3Productivity
If the system is divided into multiple layers with separate monitoring, then restart impact is minimized, but measurement and detection difficulty increases
Solution Approach 1:
Each monitoring unit is assigned to monitor a specific layer, simplifying the detection task for each individual unit. The first monitoring unit monitors the control unit layer, the second monitors the operating system layer, and the third monitors the application program layer. This segmentation makes defect detection more manageable by reducing the scope of monitoring for each unit while maintaining comprehensive system coverage.
