Thoroughly Validate the Performance of C-V2X Designs

Introduction

Autonomous driving is the future of automotive technology. Vehicle-to-everything (V2X) technology is crucial to enabling communication between vehicles and infrastructure in autonomous driving. The concept of a fully connected system emerges with cellular vehicle-to-everything (C-V2X). With C-V2X, vehicles talk with other vehicles, roadside infrastructure, and mobile networks while working to keep those nearby at a safe distance. C-V2X enables vehicle automation, reliability, dependability, and safety. Achieving the desired performance and communication quality requires V2X testing of autonomous vehicles (AVs) during research and development.

Use Case Summary

As 5G evolves, the requirements for C-V2X testing will be a moving target. The ability to thoroughly validate the performance of C-V2X designs depends on a test platform. The platform must perform RF, protocol, and application layer testing while staying current with changing test scenarios. When performing V2X testing, building a real scenario is time-consuming and difficult to repeat in extreme scenarios. In addition, the driver’s safety is at risk, and efficiency is much lower.

Therefore, it is necessary to conduct V2X hardware-in-the-loop (HIL) testing before doing a road test. HIL simulation in V2X applications is safe, accurate, and repeatable. Powerful V2X test equipment is the basis of HIL systems. V2X application launches will occur in phases, beginning with Day 1 basic services. Automotive customers need a solution to simulate scenarios, including Day 1 and 2 standard scenarios and customized scenarios, in the application layer. In addition, the solution must support access layer / intelligent transportation system (ITS) protocol stack conformance test.
