Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lack of standardized communication architectures, message structures, and operation procedures hinders efficient communication for platooning services in V2X communication, making it difficult to achieve effective platooning services that enhance driver comfort, traffic efficiency, and reduce fuel consumption.
Innovation Solution
A V2X communication device and method that includes receiving platooning information messages, determining whether to form or merge with a platooning group, and transmitting corresponding request and response messages to configure roles and locations within the group, defining message structures and operation procedures for platooning group formation, joining, leaving, merging, and dissolving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standardized communication architectures and message structures are implemented for platooning services, then communication efficiency and service reliability are improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The communication system is segmented into distinct message types (platooning information messages, concatenation request messages, concatenation response messages) with standardized structures. Each message type handles specific functions, allowing the system to manage complexity through modular design while maintaining high reliability for each individual communication function.
Solution Approach 2:
The standardized message structures are designed to be universal and multi-functional, supporting various platooning operations (formation, joining, leaving, merging, dissolving) through a common communication framework. This universality reduces the need for multiple specialized communication protocols, thereby reducing overall system complexity while ensuring reliable service delivery.
2Productivity
If message structures and operation procedures are defined for platooning group management, then service provision efficiency is improved, but communication protocol complexity increases
Solution Approach 1:
Message structures and operation procedures are predefined and standardized before actual platooning operations. Concatenation request messages and response messages follow predetermined formats, allowing vehicles to efficiently join or leave platoons without real-time negotiation of communication protocols. This preliminary standardization improves service provision efficiency while containing protocol complexity within manageable boundaries.
3Loss of energy
If V2X communication is used for platooning services, then driver comfort and fuel consumption are improved, but communication traffic and system requirements increase
Solution Approach 1:
The patent extracts and standardizes only the essential communication elements needed for platooning services (platooning information messages, concatenation requests, concatenation responses). By extracting only the necessary communication traffic required for safe and efficient platooning operations, the system achieves energy savings through reduced drag while minimizing unnecessary communication overhead.

AI summary
A method for transmitting a V2X message by means of a V2X communication device is disclosed. A V2X communication method can comprise the steps of: receiving a platooning information message from an external V2X communication device; determining, on the basis of information comprised in the platooning information message, whether or not the concatenation with a platooning group is to be formed; if it is determined that the concatenation is to be formed, transmitting a concatenation request message for requesting the concatenation to the external V2X device; receiving from the external V2X device a concatenation response message which is a response message to the concatenation request message; and forming the concatenation with the platooning group. The platooning information message can comprise information relating to a platooning group to which a vehicle having an external V2X communication device belongs.
