Tow Vehicle Trailer Pairing via Event Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing need to accurately determine which trailer is being towed by which tow vehicle, as existing monitoring systems do not effectively pair tow vehicles with trailers in real-time, especially when the same tow vehicle is used with different trailers and vice versa.
Innovation Solution
A method and system that utilize event indications from tow vehicle monitors and trailer monitors to associate and pair tow vehicles with trailers based on event type and timing proximity, with optional confidence threshold adjustments and multiple event consideration, allowing for accurate pairing even when monitors are not directly connected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If monitors are not directly connected to tow vehicles and trailers, then system complexity and installation difficulty are reduced, but pairing accuracy and reliability deteriorate
Solution Approach 1:
The patent introduces a server as an intermediary component that receives event indications from tow vehicle monitors and trailer monitors, performs pairing determinations, and manages the pairing database. This intermediary approach allows the system to maintain low complexity at the vehicle/trailer level while achieving high pairing accuracy through centralized intelligent processing.
2Speed
If pairing is determined using single event indications, then processing speed is improved, but pairing reliability deteriorates due to false associations
Solution Approach 1:
The system performs preliminary filtering and analysis of event indications before final pairing determination. It pre-establishes pairing relationships based on initial event matching, then validates and refines these pairings using additional event data, confidence thresholds, and temporal proximity analysis to ensure reliability.
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors pairing confidence levels and adjusts pairing decisions based on accumulated event data. When confidence thresholds are not met, the system waits for additional confirming events before finalizing pairings, ensuring high reliability while maintaining efficient processing.
3Measurement precision
If multiple event indications are analyzed for pairing, then pairing accuracy is improved, but processing time and computational load increase
Solution Approach 1:
The system analyzes multiple event indications but applies selective processing based on confidence thresholds. When initial events provide sufficient confidence for pairing, the system finalizes the pairing without requiring exhaustive analysis of all possible events. This partial action approach maintains high accuracy while minimizing unnecessary processing time.

AI summary
A method for pairing between a tow vehicle and a trailer, the method may include receiving a tow vehicle event indication and a trailer event indication; wherein the tow vehicle event indication is generated by a tow vehicle monitor that is arranged to monitor the tow vehicle; wherein the trailer event indication is generated by a trailer monitor that is arranged to monitor the trailer; determining, in response to a relationship between the tow vehicle event indication and the trailer event indication, whether the tow vehicle event indication and the trailer event indication are associated with a same event; and pairing the trailer and the tow vehicle is it is determined that the tow vehicle event indication and the trailer event indication are associated with the same event.
