Vehicle System Conditioning Control for Timely Shutdown
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle system conditioning methods often fail to align available conditioning time with actual needs, leading to inefficient energy usage, delayed shutdowns, and increased wear on components, as they rely on timer settings rather than real-time system requirements.
Innovation Solution
A computer system with processing circuitry that determines the need for conditioning based on active or inactive vehicle system modes, delays shutdowns to initiate conditioning only when necessary, and allows for override or cancellation of conditioning requests to optimize performance and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If timer-based conditioning is used to ensure vehicle systems are ready for use, then system reliability is improved, but energy consumption increases and shutdown delays occur
Solution Approach 1:
The system performs conditioning actions in advance based on predicted usage patterns. The control unit determines when conditioning is actually needed versus when it can be deferred, allowing the system to prepare components before they are required while avoiding unnecessary early conditioning that would waste energy.
Solution Approach 2:
The conditioning schedule is made dynamic rather than static. The control unit continuously monitors system state and adjusts conditioning timing based on actual conditions, allowing the system to adapt conditioning intervals to real-time needs rather than following fixed timer schedules, thereby reducing unnecessary energy consumption.
2Reliability
If timer-based conditioning is used to maintain system performance, then system reliability is improved, but shutdown timing is delayed
Solution Approach 1:
The system performs necessary conditioning actions in advance before the scheduled shutdown time. By determining the actual conditioning needs and completing them early, the system ensures performance requirements are met while allowing the shutdown to proceed on time without delays.
Solution Approach 2:
The control unit continuously monitors system state and conditioning progress, using this feedback to adjust shutdown timing dynamically. When conditioning is completed ahead of schedule or determined to be unnecessary, the shutdown is advanced accordingly, eliminating delays while maintaining system performance.
3Measurement precision
If frequent wakeups are used to check system needs, then conditioning accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous or frequent wakeups, the system uses periodic monitoring at optimized intervals. The control unit determines appropriate monitoring frequencies based on system state and conditioning progress, reducing the number of wakeups needed while maintaining sufficient accuracy in determining when conditioning is required.
Solution Approach 2:
The system uses passive monitoring and event-triggered wakeups rather than active continuous checking. Components can signal when they need conditioning or when conditioning is complete, allowing the control unit to wake only when necessary rather than frequently checking system state, thereby reducing energy consumption while maintaining conditioning accuracy.
4Reliability
If unnecessary conditioning is performed to ensure system readiness, then system reliability is improved, but component wear increases
Solution Approach 1:
The system performs conditioning only when actually needed based on predicted usage and current system state, rather than routinely conditioning all components in advance. By accurately determining which components require conditioning and when, the system avoids unnecessary conditioning cycles that would increase component wear while still ensuring readiness when required.
Solution Approach 2:
The conditioning strategy is dynamically adjusted based on actual system needs rather than following fixed routines. The control unit monitors component state and determines conditioning necessity in real-time, allowing the system to condition only when beneficial for reliability rather than performing unnecessary conditioning that would accelerate wear.
