Satisfying Dongfeng Motor C-V2X HIL Subsystem Requirements
For a C-V2X HIL subsystem, a platform capable of emulating fading of RF signals in real-world environments is required to simulate the performance of C-V2X receivers under vehicle-in-motion scenarios. Challenges may emerge in emulating the dynamic changes of RF signals of multiple vehicles in various C-V2X scenarios , including downtown intersections, downtown curves, expressway straight lanes, and expressway curves. It is to evaluate C-V2X receiver performance in C-V2X HIL systems in a more realistic way (with complicated live network environment). Due to different relative positions, relative speeds and complex surrounding environments, the dynamic environments for C-V2X signal transmission are very complicated, and the current C-V2X standardization is still on-going. Now some organizations have been collecting real-world field V2I and V2V data for modeling, hoping to generate recommended channel models for lab tests. With these models collected in real-world, some lab instruments are required to create models in labs and replay them faithfully, and this part of the effort will be completed with Spirent channel modeling expert team and its powerful VERTEX platform.
For the channel emulator to address the need of a C-V2X HIL subsystem, Dongfeng Motor has the following detailed requirements:
It is required to emulate point-to-point link level C-V2X scenarios, supporting C-V2X bands and bandwidth for C-V2X receiver performance tests.
Emulating dynamic V2I and V2V scenarios.
Emulating MESH propagation scenarios for multiple nodes (multiple vehicles and roadside units - RSU).
Supporting complex modeling capabilities.
It is required to support automated testing capabilities and the ability to be integrated with C-V2X HIL subsystems.
