Trailer Motion Monitoring for Inattentive Commercial Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver monitoring systems fail to effectively detect inattentive driving in commercial vehicles, which can lead to decreased safety and efficiency, particularly in fleet operations where timely intervention is necessary.
Innovation Solution
A method that monitors the motion of a vehicle trailer to identify trends indicative of inattentive driving by comparing trailer motion with known trends, using a combination of image-based monitoring and sensor data from trailer wheel speed, lane detection, and road edge sensors, and responds by storing video footage from a driver monitoring system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trailer motion monitoring is implemented to detect inattentive driving, then driver safety and operational efficiency are improved, but system complexity and cost increase
Solution Approach 1:
The patent uses trailer motion as an intermediary indicator to indirectly detect driver attentiveness. Instead of directly monitoring the driver's state, the system monitors trailer motion patterns which are affected by driver behavior, providing a reliable safety indicator without requiring direct driver monitoring equipment
Solution Approach 2:
The trailer monitoring system serves multiple functions: it detects inattentive driving, provides operational data for fleet management, and can identify various driving events. This multi-functionality improves reliability while distributing the complexity across different system components
2Measurement precision
If multiple monitoring methods (image-based and sensor data) are combined to identify motion trends, then detection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent combines image-based monitoring and sensor data monitoring into a unified trailer motion monitoring system. By merging these different monitoring approaches, the system achieves higher detection accuracy through multiple data sources while managing complexity through integrated processing
Solution Approach 2:
The system uses feedback from multiple monitoring sources (image-based and sensor data) to continuously refine motion trend identification. This feedback mechanism improves detection accuracy by validating findings across multiple data streams and reducing false positives
3Loss of time
If trailer motion monitoring is used to detect inattentive driving, then timely intervention is enabled, but data processing requirements and energy consumption increase
Solution Approach 1:
The system performs preliminary monitoring of trailer motion continuously to establish baseline patterns and detect deviations early. This preliminary action enables timely intervention by identifying inattentive driving trends before they lead to safety incidents, reducing response time while managing energy through proactive detection
Data Source
AI summary
A method for detecting inattentive vehicle operation in a commercial vehicle includes monitoring a motion of a rear portion of a trailer and identifying a motion trend. The method compares the motion trend with a set of known inattentive driving trends and identifies an inattentive driving event when the identified trend matches a known inattentive driving trend in the set of known inattentive driving trends.
