Predictive Vehicle Maintenance System Using Sensor Earmarks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle maintenance systems are reactive and do not proactively address the underlying causes of faults, leading to excessive downtime and additional repair costs, as they typically perform maintenance only after a vehicle has broken down.
Innovation Solution
A preventative vehicle maintenance system equipped with electronic control modules (ECMs) that collect data from sensors, statistically analyze it to identify predictive earmarks of potential faults, and generate alert codes to facilitate proactive repairs before failures occur.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional reactive maintenance systems are used, then maintenance is performed only after breakdown, but this results in excessive downtime and additional repair costs
Solution Approach 1:
The system performs preliminary actions by continuously monitoring sensor data and statistically analyzing it to identify earmarks that predict potential faults before they occur. This allows maintenance to be scheduled in advance, preventing breakdowns and reducing unplanned downtime.
Solution Approach 2:
The system implements feedback by continuously collecting sensor data, comparing it against statistical thresholds, and generating alert codes when potential faults are detected. This closed-loop feedback enables proactive identification and resolution of issues before they cause vehicle failure.
2Reliability
If conventional reactive maintenance systems are used, then maintenance is performed only after breakdown, but this leads to additional repair costs
Solution Approach 1:
By performing maintenance in advance based on predicted faults, the system prevents catastrophic failures that would require expensive emergency repairs. Routine maintenance scheduled proactively is less costly than reactive repair after breakdown.
3Reliability
If statistical analysis of sensor data is performed to identify predictive earmarks, then potential faults can be detected early, but this requires complex data processing and analysis systems
Solution Approach 1:
The system performs self-service by automatically collecting sensor data, conducting statistical analysis, identifying earmarks, and generating alert codes without requiring external intervention. This automation reduces the need for complex manual analysis systems while maintaining high prediction accuracy.

AI summary
A system that enables a fleet of vehicles to be maintained is provided. The disclosed system allows a fleet operator to review the history of the vehicles in the fleet along with vehicle sensor data to identify earmarks in the vehicle sensor data that are predictive of faults that the vehicles have experienced. The operator develops statistical algorithms that can detect an earmark in vehicle sensor data. The system then collects vehicle sensor data and applies the statistical algorithms the vehicle data to determine if a potential fault is going to occur in a vehicle. In response to determining that a potential fault is going to occur, the disclosed system automatically alerts the vehicle driver, automatically schedules a maintenance visit, automatically checks the fleet inventory for components required for a maintenance visit and orders unavailable components, and automatically dispatches the components to the mechanic.
