V2X Communication Apparatus Bridging ITS-G5 and C-V2X Standards
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle-to-X communication technologies, such as ITS-G5 and C-V2X, are inherently incompatible, limiting their potential for enhancing road user safety as vehicles equipped with one technology cannot receive messages from those using another.
Innovation Solution
A communication apparatus with both ITS-G5 and C-V2X interfaces that converts signals between these incompatible technologies, allowing for comprehensive communication across different standards and manufacturers, and efficiently utilizes existing bandwidth by filtering and processing messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If vehicles are equipped with only one V2X communication technology (ITS-G5 or C-V2X), then the device complexity is reduced, but the adaptability to different communication standards deteriorates
Solution Approach 1:
The communication apparatus is designed with dual V2X interfaces supporting both ITS-G5 and C-V2X technologies, enabling a single device to perform multiple communication functions and interact with vehicles using different standards, thereby achieving universal compatibility without requiring separate dedicated devices for each standard
Solution Approach 2:
The apparatus acts as an intermediary between ITS-G5 and C-V2X networks by receiving messages from one standard through its corresponding interface, processing the information, and retransmitting it through the other interface, thus mediating communication between incompatible systems
2Productivity
If all received V2X messages are transmitted without filtering, then the loss of information is minimized, but the bandwidth utilization deteriorates
Solution Approach 1:
Instead of transmitting all received messages indiscriminately, the apparatus selectively transmits only relevant messages based on predefined criteria such as message type, source vehicle characteristics, and situational context, thereby achieving partial transmission that optimizes bandwidth usage while maintaining essential information flow
Solution Approach 2:
The apparatus evaluates received messages against transmission criteria before forwarding, creating a feedback mechanism that determines message relevance and prioritizes important safety-critical information over less critical data, thus improving bandwidth efficiency without losing essential information

AI summary
A communication apparatus for vehicle-to-X communication (V2X communication), including: a first V2X interface for transmitting and/or receiving vehicle-to-X messages by a first wireless communication technology, a second V2X interface for transmitting and/or receiving vehicle-to-X messages by a second wireless communication technology. Wherein the apparatus is configured to transmit information, which is received with a vehicle-to-X message by the first interface, by the second interface. The information received or respectively to be transmitted can be expediently had by at least one appropriate vehicle-to-X message received or respectively to be transmitted. A corresponding method as well as the use of the apparatus is also provided.
