Crowdsourced Sensor Data for Autonomous Vehicle Failure Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles lack the ability to detect subtle mechanical issues due to their reliance on machine control, which can lead to inefficient maintenance and potential safety hazards, as they lack the human intuition to identify unusual sounds or vibrations.
Innovation Solution
A universal smart sensor module is deployed on autonomous vehicles to gather acoustic and vibrational data, which is then crowdsourced and analyzed using machine learning techniques to identify discrepancies and predict potential failures, allowing for proactive maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If autonomous vehicles rely on machine control, then processing speed and data bandwidth are improved, but the ability to detect subtle mechanical issues through human intuition is lost
Solution Approach 1:
The patent combines machine-based sensor data collection with human expert analysis. Sensors continuously gather acoustic and vibrational data from vehicles, which is then transmitted to remote experts who provide intuitive diagnostic assessment. This merging allows the system to retain both the processing speed of machines and the detection capability of human intuition.
Solution Approach 2:
The patent introduces a crowdsourced data platform as an intermediary between vehicle sensors and maintenance decision-making. The platform aggregates data from multiple vehicles and enables remote experts to analyze patterns that individual machines might miss, while still providing structured data for automated processing. This intermediary layer bridges the gap between machine efficiency and human expertise.
2Productivity
If traditional maintenance schedules are used, then maintenance is performed regularly, but unexpected failures still occur due to inability to detect subtle issues
Solution Approach 1:
The patent implements preliminary detection of failure modes by continuously monitoring acoustic and vibrational data before actual failures occur. Remote experts analyze sensor data to identify early signs of mechanical issues, allowing maintenance to be scheduled proactively rather than reactively. This preliminary action enables the system to predict failures before they happen, improving both reliability and maintenance efficiency.
Solution Approach 2:
The patent establishes a feedback loop where sensor data from vehicles is continuously transmitted to a crowdsourced platform, analyzed by experts, and used to update maintenance schedules and predictions. The system learns from aggregated data across multiple vehicles, improving its ability to predict failures. This feedback mechanism allows the system to adapt and improve over time, enhancing both productivity and reliability.
3Loss of information
If sensors are deployed on individual vehicles, then data collection is improved, but data bandwidth and analysis capability are insufficient without crowdsourcing
Solution Approach 1:
The patent merges data from multiple vehicle sensors into a centralized crowdsourced platform. Instead of each vehicle operating independently, the system combines acoustic and vibrational data across the entire fleet, enabling pattern recognition and failure prediction that would be impossible with individual vehicle data alone. This merging approach improves information completeness while distributing processing complexity across the network.
Solution Approach 2:
The patent creates a universal data platform that serves multiple functions: data aggregation, pattern recognition, failure prediction, and maintenance scheduling. The same infrastructure that collects sensor data also performs analysis and generates maintenance recommendations, reducing overall system complexity while improving data utilization. This multi-functional approach allows the system to handle large data volumes efficiently.
