Trailer V2X Communication Module for Consistent Low-Latency Data Exchange
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems often result in inconsistent data when multiple communication modules are installed within a vehicle, leading to unusable data due to contradictions, and trailers lack autonomous and standardized communication capabilities for exchanging data with road users.
Innovation Solution
A method for a trailer communication module to establish a low-latency V2X wireless data connection with road users, allowing autonomous and standardized data exchange, independent of the towing vehicle's infrastructure, using direct or indirect connections via a distribution station, and enabling the trailer to select and transmit data based on the road user, with operating modes for coupling, interface, and free modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication modules are installed within a vehicle (towing vehicle and trailer), then data exchange capability is improved, but data consistency deteriorates due to contradictions
Solution Approach 1:
The system segments the communication function by installing separate communication modules in the towing vehicle and trailer, each capable of independent V2X communication. This segmentation allows each module to operate autonomously while maintaining data consistency through standardized protocols, resolving the contradiction between enhanced data exchange capability and data consistency.
2Extent of automation
If a trailer communication module is installed for autonomous communication, then communication independence is improved, but device complexity increases
Solution Approach 1:
The trailer communication module is designed with multi-functionality to handle various communication scenarios (coupled mode, uncoupled mode, different road user interactions) through a single standardized V2X interface. This universal design enables autonomous communication without requiring multiple specialized modules, thus improving communication independence while controlling device complexity.
3Loss of time
If direct V2X connection is established between trailer and road users, then communication latency is reduced, but connection reliability worsens due to wireless instability
Solution Approach 1:
The distribution station acts as an intermediary in the V2X communication architecture, providing a stable relay point for data transmission between the trailer communication module and road users. This intermediary approach maintains low latency through efficient routing while improving connection reliability by utilizing the infrastructure-based communication path when direct wireless connections are unstable.
Data Source
AI summary
A method for transmitting data between a trailer and a road user in a vehicle environment is provided, wherein the data are transmitted according to a V2X standard with low latency via a wireless V2X data connection between a trailer communication module of the trailer and a subscriber communication module of the road user. The wireless data connection is between the trailer communication module and the subscriber communication module, or indirectly via a distribution station. The distribution station forwards the transmitted data directly, wherein the trailer communication module autonomously selects and activates an operating mode depending on the respective road user. As a function of the activated operating mode, trailer data relating to the trailer are selected and autonomously transmitted according to the V2X standard via the wireless V2X data connection and/or subscriber data provided by road users are received and autonomously processed.
