C-V2X test system speeds V2X development
Technology News |
National Instruments (NI) has introduced an open-loop test system for vehicle-to-X communication based on the C-V2X standard. This uses 5G wireless cellular technology to provide high-bandwidth, low-latency communication for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastucture (V2I) communications.

In developing the system, National Instruments is working with partner S.E.A. Datentechnik GmbH to realize the full potential of networked and intelligent mobility. To this end, a software-defined approach will be provided with which OEMs and Tier 1 suppliers can validate the safety and efficiency of the vehicles. With the evolution of 3GPP standards, including the ability to 5G-NR with 3GPP version 16 planned for 2020, a software-defined platform offers OEMs and Tier-1 suppliers the flexibility to adapt to the latest technology with few hardware and software changes.

C-V2X leverages mobile communications technology for the physical layer and benefits from significant investments in mobile communications, such as 5G, and a broad technology environment. For this technology to work, all stakeholders need to standardize communication, understand the interaction between multi-vendor systems, and describe behavior in real-world scenarios.  It is expected that 5G will provide higher throughput and less waiting time for autonomous vehicle communication, high-resolution map downloading and enhanced pedestrian interactions. As most projects are still in the early stages of evaluation and standards need to be developed, OEMs, automotive suppliers and researchers are investing in tools that can adapt to the evolution of C-V2X technology.

The solution at hand combines software from NI Alliance Partner S.E.A. with software defined radio (SDR) systems from NI. The system is capable of simulating emergency braking and crossing rituals, among other things. The platform includes precompiled driving scenarios such as left-turn assistant, emergency brake warning and congestion warning to shorten the time to first measurement.

The C-V2X standard competes on the market with the older IEEE 802.11p standard. Unlike the latter, C-V2X can also use cellular networks to send alert messages. A real benefit for this feature however is expected only with the roll-out of 5G networks.
