Parked Vehicle Abnormality Detection for Fleet Isolation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle management systems do not adequately prevent other vehicles from being affected by abnormalities, such as cyber attacks or component failures, in one moving body.
Innovation Solution
A moving body management system comprising a moving body management device with a reception unit to receive detection results of abnormalities from stopped moving bodies and a moving body control device with a detection unit to detect abnormalities when the moving function is stopped, and a transmission unit to send these detection results to the management device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a moving body is stopped to detect abnormalities, then detection accuracy is improved, but productivity deteriorates due to movement interruption
Solution Approach 1:
The system performs abnormality detection during the stopped period before the moving body is put back into service. This preliminary detection ensures that any abnormalities are identified and addressed before they can affect operational safety or lead to more serious failures during movement, thus maintaining detection accuracy without compromising overall productivity.
2Reliability
If abnormality detection is performed continuously during movement, then reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring during movement, the system performs abnormality detection periodically when the moving body is stopped. This periodic action maintains system reliability by regularly checking for abnormalities while significantly reducing energy consumption compared to continuous monitoring, as the detection device only operates during stopped periods.
3Loss of information
If detection results are transmitted immediately upon detection, then information freshness is improved, but communication load increases
Solution Approach 1:
The system merges multiple detection results and transmits them together during stopped periods rather than transmitting each detection result immediately upon detection. This approach maintains information freshness by ensuring timely transmission of aggregated data while reducing communication load and system complexity by consolidating transmission events.

AI summary
A vehicle management system corresponding to a moving body management system includes: a vehicle management device corresponding to a moving body management device including a reception unit that receives a detection result of an occurrence status of an abnormality at a predetermined timing from a parked vehicle corresponding to a moving body whose moving function is stopped; and a vehicle control device corresponding to a moving body control device including a detection unit that detects an occurrence status of an abnormality when a vehicle corresponding to a moving body including the moving body control device is parked, and a transmission unit that transmits a detection result from a detection unit to the vehicle management device.
