Vehicle Controller Compensation for Aging and Abnormality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Departed Driver Rescue and Exit Maneuver (DDREM) technology only provides an alarm for aging or abnormal vehicle controllers, failing to maintain basic performance through compensatory control.
Innovation Solution
A vehicle integrated controller that detects aging or abnormality in vehicle controllers, calculates a control parameter to maintain basic performance, and performs compensatory control using an in-vehicle communication module, collection module, aging abnormality processor, and parameter controller, which includes a controller state analysis module, controller state learning module, and parameter controller to generate control information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If conventional DDREM technology only provides alarm function for controller aging or abnormality, then the system complexity is reduced, but the controller performance maintenance capability deteriorates
Solution Approach 1:
An aging abnormality processor is introduced as an intermediary component between the controller and the alarm system. This processor collects controller information, analyzes aging states, calculates compensation values, and generates compensatory control commands. The intermediary enables performance maintenance without requiring complete system redesign.
Solution Approach 2:
The system changes control parameters dynamically based on detected aging states. The aging abnormality processor calculates compensation values by adjusting control parameters in real-time to offset the effects of controller aging, thereby maintaining basic performance despite degradation.
2Reliability
If compensatory control is added to maintain basic performance, then the controller performance maintenance capability is improved, but the device complexity increases
Solution Approach 1:
The aging abnormality processor merges multiple functions into a single integrated module: information collection, aging analysis, compensation calculation, and control command generation. This consolidation achieves performance maintenance while limiting complexity increase through functional integration.
Solution Approach 2:
The controller system performs self-diagnosis and self-compensation through the aging abnormality processor. The system automatically detects its own aging state and generates compensatory control commands without external intervention, enabling autonomous performance maintenance.
3Reliability
If controller aging is detected and compensatory control is applied, then the basic performance is maintained, but the response time increases
Solution Approach 1:
The aging abnormality processor continuously collects controller information and analyzes aging states in advance, before significant performance degradation occurs. By detecting aging early and applying compensatory control proactively, the system maintains performance without requiring time-consuming reactive adjustments.
Solution Approach 2:
The system implements continuous feedback by monitoring controller state information, comparing it against aging models, and adjusting control parameters in real-time. This closed-loop feedback mechanism ensures rapid response to aging effects while maintaining basic performance.
