Vehicle Control Module Allocation Under Resource Constraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face challenges in efficiently allocating applications to control modules due to resource limitations and unavailability, leading to potential operational inefficiencies and reliability issues.
Innovation Solution
A master controller allocates applications to control modules based on dependencies and resource limitations, using a set of dependencies and prioritization to ensure maximum resource utilization and reliable operation, with a backup master controller taking over in case of primary controller unavailability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If applications are allocated to control modules based on default assignment, then system simplicity is maintained, but resource utilization efficiency deteriorates when modules are unavailable
Solution Approach 1:
The patent implements dynamic application allocation where the master controller continuously monitors control module availability and reassigns applications in real-time based on current system state, transitioning from static default assignment to adaptive dynamic allocation to optimize resource utilization
Solution Approach 2:
The system establishes a feedback loop where control modules report their availability status to the master controller, which then adjusts application allocation accordingly, enabling the system to respond to changing conditions and maintain optimal performance
2Productivity
If control modules operate independently without centralized allocation, then system reliability is improved through distribution, but operational efficiency deteriorates due to suboptimal resource utilization
Solution Approach 1:
The master controller serves as an intermediary between control modules and applications, coordinating resource allocation and monitoring module availability to balance centralized optimization with distributed system resilience
Solution Approach 2:
The allocation system is designed to handle multiple functions including normal application deployment, failure detection, dynamic reassignment, and backup activation, allowing a single system to adapt to various operational scenarios
3Reliability
If critical applications are prioritized over non-critical ones, then system reliability is improved, but resource allocation flexibility deteriorates
Solution Approach 1:
The patent applies different allocation strategies to different applications based on their criticality level, with critical applications receiving guaranteed resource allocation and higher priority during failures, while non-critical applications can be reassigned more freely to optimize overall system utilization
