Tractor-Trailer Authentication for Secure Coupling and EPB Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The automatic transportation system between logistics hubs lacks authentication and communication between tractors and trailers, leading to incorrect coupling and lack of control over the Electronic Parking Brake (EPB), resulting in potential safety and efficiency issues.
Innovation Solution
A system and method that utilize a control server to authenticate and communicate identification information between tractors and trailers, allowing correct coupling and release of the EPB, preventing incorrect coupling and ensuring secure communication through encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication and communication systems are added between tractors and trailers, then coupling accuracy and safety are improved, but device complexity increases
Solution Approach 1:
The patent introduces a control server as an intermediary that manages authentication between tractors and trailers. The control server receives identification information from both vehicles, performs verification, and coordinates the coupling process. This mediator approach centralizes the complex authentication logic, preventing incorrect couplings while maintaining manageable system complexity through dedicated control infrastructure.
Solution Approach 2:
The system performs preliminary authentication and verification of identification information before allowing physical coupling to occur. The control server verifies the tractor and trailer identities in advance, ensuring that only authorized pairs can couple. This preliminary action prevents incorrect couplings and enhances safety before the actual coupling operation takes place.
2Reliability
If real-time communication and authentication protocols are implemented, then operational safety is improved, but communication overhead and processing time increase
Solution Approach 1:
The control server performs authentication and verification of identification information in advance before coupling operations. By completing the safety verification process preliminarily, the system ensures operational safety is maintained while the actual coupling can proceed efficiently once authentication is complete, reducing delays during critical coupling moments.
3Productivity
If the Electronic Parking Brake (EPB) release control is automated through authentication, then coupling efficiency is improved, but control system complexity increases
Solution Approach 1:
The patent combines the EPB release control with the authentication and coupling verification processes. When the control server confirms successful authentication and proper coupling of the tractor and trailer, it automatically triggers the EPB release. This merging of functions automates the brake release operation, improving coupling efficiency by eliminating manual intervention while integrating the control logic into the existing authentication framework.

AI summary
A system and method for managing a tractor-trailer and a method are provided. The system includes: a control server to manage a position of a trailer, identification information on the trailer, and identification information on a tractor matched to the trailer with respect to each hub; a trailer to authenticate the tractor by comparing the identification information, which is received from the control server, on the tractor, with identification information received from the tractor, and to release an electronic parking brake (EPB) when an authentication result for the tractor is correct; and a tractor to authenticate the trailer by comparing the identification information, which is received from the control server, on the trailer with identification information received from the trailer to authenticate the trailer, and to be coupled to the trailer, when an authentication result for the trailer is correct.
