Tractor-Trailer Pairing Confirmation via ABS Identifier Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack a reliable method to confirm that the physical pairing between a tractor and trailer matches the intended pairing in the trucking schedule, leading to errors and inefficiencies in cargo delivery.
Innovation Solution
A system and method utilizing a trailer controller capable of short-range wireless communications and an electronic control unit to generate an ABS check signal with a unique trailer identifier, establishing a short-range wireless connection with the tractor for confirmation, and comparing identifiers through both wired and wireless channels to ensure correct pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual pairing confirmation is used between tractor and trailer, then operational simplicity is maintained, but pairing accuracy deteriorates leading to wrong connections
Solution Approach 1:
The patent replaces manual visual confirmation and physical coupling checks with electronic identification systems. The tractor and trailer use electronic control units that automatically exchange identification data through the physical coupling connection, substituting human judgment with automated electronic verification to eliminate pairing errors.
Solution Approach 2:
The patent uses identification signals that are transmitted electronically between tractor and trailer control units. These electronic copies of identification data allow verification of pairing without requiring physical inspection or manual confirmation, enabling accurate matching through data replication rather than human assessment.
2Reliability
If automated identification systems are implemented, then pairing accuracy improves, but device complexity increases
Solution Approach 1:
The patent integrates the identification system into existing vehicle control units (ECUs) that already manage braking and other safety functions. By making the control units multi-functional—handling both traditional vehicle operations and identification verification—the system achieves high reliability without adding separate dedicated identification hardware for each vehicle.
Solution Approach 2:
The patent combines the identification transmission function with the existing physical coupling mechanism. The same electrical connection used for braking system communication also carries identification data, merging multiple functions into a single integrated system rather than requiring separate identification hardware and communication channels.
3Reliability
If multiple verification methods are used, then pairing confirmation reliability improves, but ease of operation deteriorates
Solution Approach 1:
The patent enables the tractor and trailer systems to automatically verify their own pairing through electronic identification exchange. The control units autonomously compare identification data and confirm correct pairing without requiring driver intervention or manual verification steps, maintaining operational simplicity while achieving high confirmation reliability through self-verification.
Solution Approach 2:
The system provides automatic feedback to the driver regarding pairing status. The control units exchange identification data and provide confirmation signals (such as visual or audible indicators) that inform the driver whether the pairing is correct, eliminating the need for manual verification while maintaining ease of operation through automated information feedback.

AI summary
A system for confirming pairing of a tractor and a trailer includes the trailer having: a controller, capable of short-range wireless communications; and an electronic control unit (ECU), configured to generate and transmit an anti-lock braking system (ABS) check signal including a unique trailer identifier to the tractor, such that a short-range wireless connection between the controller and the tractor is established using the unique trailer identifier transmitted with the ABS check signal.
