Vehicle Dual-RAT V2X Modules for Regional Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vehicle manufacturers face challenges in offering V2X communication functions in different markets due to variant diversity between IEEE 802.11p and C-V2X standards, leading to increased development, production, logistics, and sales costs.
Innovation Solution
An apparatus and method that includes both IEEE 802.11p and C-V2X communication modules, with a controller selecting the appropriate module based on the vehicle's region or territory, using static or dynamic control information such as hardcoded country codes, user language, location determination, or message detection, to ensure compatibility with local communication standards.

Engineering Contradiction Analysis
1Adaptability or versatility
If vehicle manufacturers use different V2X communication modules for different markets, then V2X communication compatibility is improved, but development, production, logistics and sales costs increase
Solution Approach 1:
The patent implements a universal V2X communication module that supports multiple communication standards (IEEE 802.11p and C-V2X) within a single device. The module includes a controller that can switch between different communication protocols based on the operational region, eliminating the need for separate dedicated modules for each market. This multi-functional approach maintains compatibility across different regions while reducing device variant diversity.
Solution Approach 2:
The V2X communication module incorporates a dynamic switching mechanism that allows it to adapt its communication protocol based on the detected operational region. The controller receives region information and dynamically selects the appropriate communication standard (IEEE 802.11p for certain regions, C-V2X for others), enabling the module to change its behavior based on environmental conditions rather than being fixed for a single market.
2Adaptability or versatility
If vehicles are equipped with multiple V2X communication modules, then adaptability to different regions is improved, but device complexity increases
Solution Approach 1:
The system performs preliminary detection of the operational region using region detection information (such as GPS location or network-based detection) before the vehicle begins V2X communication. Based on this pre-detection, the controller pre-selects the appropriate communication module or protocol configuration, avoiding the need for complex real-time decision-making during communication operations.
Solution Approach 2:
The V2X communication module includes self-configuring capabilities where the controller automatically detects the operational region and selects the appropriate communication protocol without requiring manual intervention. The system uses region detection information to autonomously determine which communication standard to employ, reducing the complexity of manual module selection and configuration.

AI summary
The present disclosure relates to a concept for wireless Vehicle-to-everything, V2X, communication of a vehicle. A first communication module configured to provide V2X communication based on a first Radio Access Technology (RAT). A second communication module is configured to provide V2X communication based on a second RAT. A controller is configured to select either the first or the second communication module for V2X communication based on a territory the vehicle is operated in.
