Trailer Communication Circuit Using C-V2X for Reliable Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trailer assistance systems require additional technical methods and mechanisms for communication between a transportation vehicle and a trailer, increasing costs and complexity, as existing technologies do not efficiently utilize existing communication standards for vehicle-to-everything (C-V2X) for trailer assistance.
Innovation Solution
Implementing communication technology configured for separate transportation vehicles, such as WLANp or C-V2X, to enable communication between a transportation vehicle and a trailer, using standardized Collective Perception Messages (CPM) and Cooperative Awareness Messages (CAM), which reduces the need for additional components and mechanisms in the transportation vehicle, allowing the trailer to relay information and enhance communication range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional technical methods and mechanisms are implemented for trailer communication, then communication reliability between vehicle and trailer is improved, but device complexity and manufacturing costs increase
Solution Approach 1:
The patent applies universality by enabling the vehicle's existing C-V2X communication system to serve dual purposes: communicating with other vehicles and communicating with the trailer. The trailer is equipped with a C-V2X communication device that allows it to participate in the vehicle's existing communication network, eliminating the need for separate dedicated communication systems and achieving multi-functionality from a single communication infrastructure.
Solution Approach 2:
The trailer performs self-service by autonomously equipping itself with a C-V2X communication device and independently establishing communication with the vehicle. The trailer's control unit autonomously determines communication parameters and manages the communication connection without requiring additional vehicle-side mechanisms, thereby reducing overall system complexity while maintaining reliability.
2Ease of manufacture
If standardized C-V2X communication technology is used for trailer assistance, then ease of manufacture and compatibility are improved, but communication precision and environmental assessment capability worsen
Solution Approach 1:
The patent merges the trailer's communication needs with the vehicle's existing C-V2X infrastructure. By combining the vehicle's communication capabilities with the trailer's equipped C-V2X device, the system achieves standardized, easy-to-manufacture implementation while maintaining precise environmental assessment through the integrated communication channel that shares the vehicle's high-precision communication resources.
3Adaptability or versatility
If the trailer is equipped with communication technology for separate transportation vehicles, then communication range and versatility are improved, but device complexity increases
Solution Approach 1:
The trailer's C-V2X communication device provides universality by enabling the trailer to communicate not only with its attached vehicle but also with other vehicles and infrastructure in the environment. This single multi-functional device replaces what would otherwise require multiple specialized communication systems, achieving high versatility without proportionally increasing complexity.
