Car2X Message Translation via Universal Adapter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of Car2X applications is hindered by the need to create separate versions for different regional standards, such as European Cooperative Awareness Messages (CAM) and North American Basic Safety Messages (BSM), leading to inefficiencies and limited cross-regional compatibility.
Innovation Solution
A processing device and control unit that convert and generate Car2X messages based on previously known content, allowing for adaptation to specific standards, enabling efficient message processing and evaluation by recognizing and utilizing relevant data fields, even if not all content is present, to create new messages compatible with the target standard.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate application versions are developed for different regional standards (European CAM/DENM and North American BSM), then each application can be optimized for its specific standard, but the development effort and complexity double
Solution Approach 1:
The patent implements a universal message processing architecture where a single application can handle multiple regional standards (European CAM/DENM and North American BSM) through a standardized internal message format. The system includes a message adapter layer that translates incoming messages from different standards into a common internal representation, allowing the core application logic to remain unchanged while supporting multiple standards.
Solution Approach 2:
The patent introduces an intermediary message adapter component that sits between the external message sources (different regional standards) and the core application. This adapter translates and normalizes messages from various standards (CAM, DENM, BSM) into a unified internal message format, enabling the application to process messages from any standard without requiring separate application versions.
2Device complexity
If vehicles are designed for only one standard, then the vehicle's Car2X system can be simplified and optimized, but the vehicle cannot operate in regions with different standards
Solution Approach 1:
The patent implements a universal message processing architecture where a single application can handle multiple regional standards (European CAM/DENM and North American BSM) through a standardized internal message format. The system includes a message adapter layer that translates incoming messages from different standards into a common internal representation, allowing the core application logic to remain unchanged while supporting multiple standards.
Solution Approach 2:
The patent employs dynamic message routing and adaptation mechanisms that allow the Car2X system to automatically adjust its behavior based on the detected message standard. The system can dynamically switch between handling European and North American standards, enabling vehicles to operate across different regions without hardware changes or reconfiguration.
3Productivity
If messages are converted using a fixed scheme, then the conversion process is simple and fast, but the new message cannot be adapted to the specific content of the received message
Solution Approach 1:
The patent performs preliminary classification of incoming messages by identifying their type and standard before conversion. The system pre-loads relevant content from the received message that will be needed for conversion, and pre-determines the target message format based on the message type. This preliminary processing enables faster conversion while maintaining content adaptability.
Solution Approach 2:
The patent dynamically adjusts conversion parameters based on the specific content and type of the received message. Rather than using a rigid fixed scheme, the system modifies conversion parameters such as message priority, timestamp handling, and field mapping based on the detected message type (CAM, DENM, BSM) and its specific content, enabling both speed and adaptability.
4Reliability
If all content of the received message is processed when generating a new message, then the new message is complete, but the generation process becomes inefficient and slow
Solution Approach 1:
The patent extracts only the essential and relevant content from incoming messages that is necessary for generating the new message. The system identifies and extracts key fields such as position, speed, timestamp, and message type, while ignoring redundant or less critical information. This selective extraction maintains message completeness for essential data while significantly improving processing efficiency.
Solution Approach 2:
The patent implements partial processing where only the necessary portions of the received message content are processed and transferred to the new message. The system determines the minimum required content set based on the message type and processing requirements, processing only that subset rather than all available content, thereby improving efficiency while maintaining sufficient completeness for the application's needs.

AI summary
A method for processing Car2X messages by means of a processing device designed to be able to receive and process messages, the construction of which is defined according to different standards, preferably according to a first standard and a second standard, comprising the steps: recording of the message by means of the processing device, identifying the standard used by the message, forwarding the message to an application unit of the processing device if the message uses the standard for which the application unit is designed, or otherwise creating a new message from the received message so that it can be processed by means of the application unit, characterized in that the new message is created in accordance with at least one previously known content item within the received message.
