V2X Message Modification for Custom Vehicle Safety Broadcasts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle communication systems lack the ability to transmit nonstandard, user-generated messages beyond the capabilities of standard broadcast messages, limiting the flexibility and relevance of vehicle-to-everything (V2X) communications.
Innovation Solution
A system and method for modifying standard messages to create nonstandard broadcast messages using onboard communication devices, enabling user interaction through message user interfaces to append or replace content, and transmitting these messages via vehicle-to-vehicle, vehicle-to-network, and vehicle-to-pedestrian protocols, secured by a security credential management system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard broadcast messages are used for V2X communication, then system reliability and protocol compatibility are maintained, but message flexibility and user customization capability are limited
Solution Approach 1:
The message structure is segmented into standard fields (maintaining protocol compatibility) and customizable fields (enabling user flexibility). The system divides the broadcast message into predefined sections that adhere to existing V2X protocols and user-defined sections that can be customized, allowing both standard and nonstandard content to coexist in a single message framework.
Solution Approach 2:
A message modification system acts as an intermediary between standard protocol requirements and user customization needs. This intermediary component processes user-generated content, formats it according to protocol specifications, and injects it into the standard message structure, thereby mediating between the conflicting requirements of standardization and customization.
2Adaptability or versatility
If only standard messages are transmitted, then system complexity remains low, but communication functionality and user interaction capabilities are insufficient
Solution Approach 1:
The message modification system is designed to perform multiple functions: it can add custom content to standard messages, modify existing message fields, validate user input against protocol requirements, and interface with various V2X communication modes. This multi-functional approach enables enhanced communication capabilities without requiring separate systems for each function.
Solution Approach 2:
The system automatically handles the complexity of message customization by providing self-service capabilities. User-generated content is automatically formatted, validated, and integrated into standard message structures without requiring manual intervention or complex configuration, thereby reducing the perceived complexity for end users while maintaining enhanced functionality.
3Reliability
If user-generated nonstandard messages are enabled, then message relevance and safety alert effectiveness are improved, but security risks and message validation complexity increase
Solution Approach 1:
The system implements feedback mechanisms where user-generated messages are validated against protocol specifications and safety criteria before transmission. The validation process provides feedback to users about message acceptability, and the system continuously learns from message patterns to improve validation accuracy, thereby enhancing safety alert effectiveness while managing validation complexity through iterative refinement.

AI summary
Systems and methods for using a vehicle-to-vehicle broadcasting system to broadcast a nonstandard message are described herein. The systems and methods provide a user interface that allows a user to input content. The content is used to modify a standard message used in V2X communications to provide nonstandard information to other user equipment within a predetermined distance of the transmitting user equipment.
