NI introduces S.E.A. C-V2X Open Loop Test System; 5G tech for V2X

NI, the provider of a software-defined platform that helps accelerate the development and performance of automated test and automated measurement systems, announced the S.E.A. C-V2X Open Loop Test System, leveraging 5G wireless cellular technology to provide high bandwidth and low latency communication for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications.

NI is collaborating with S.E.A., an NI Alliance Partner, to help maximize the full potential of connected and intelligent mobility by providing a software-defined approach to help automotive OEMs and Tier 1 suppliers validate the safety and efficiency of the cars.

As the 3GPP standards evolve—including 5G NR capability with 3GPP Release 16 scheduled for 2020—a software-defined platform provides OEMs and Tier 1 suppliers the flexibility to adapt to the latest technology with minimum hardware and software changes.

In a 2016 study, NHTSA estimated that safety applications enabled by V2V and V2I could eliminate or mitigate the severity of up to 80 percent of non-impaired crashes, including crashes at intersections or while changing lanes. By communicating intent and gathering data from other cars about their surroundings, V2X better informs both human and autonomous driving to improve reaction time and ease decision making in vehicle interactions like cross-traffic left turns and merging into traffic.

Using cellular technology for physical layer communication, C-V2X benefits from considerable investments in cellular communication, including 5G, and a vast ecosystem of technology. For this technology to work, contributors will need to standardize on communication, understand how systems from multiple vendors interact and characterize behavior in real-world scenarios. Eventually, 5G is expected to provide increased throughput and lower latency for autonomous vehicle communications, downloading high-definition maps, and advanced pedestrian interactions. With most projects still in the early stages of evaluation and standards still materializing, automotive OEMs, automotive suppliers and academic researchers are investing in the tools that will adapt as C-V2X technology evolves.

The new C-V2X solution combines software from S.E.A. with NI software defined radio (SDR) hardware to send real signals to RF and GNSS channels on C-V2X controllers and telematics control units. By articulating the C-V2X and GNSS signals to the C-V2X controller, the new C-V2X solution can simulate real signals from an emergency brake warning or four-way stop and help engineers characterize device performance in the lab. The new C-V2X solution includes pre-compiled drive scenarios such as left turn assist, emergency brake warning and traffic jam warning to accelerate time to first measurement.

S.E.A. also provides the following software add-ons:

  • Congestion Simulation software emulates the surrounding environment, with up to several hundred cars, to increase the test coverage.

  • Channel emulation software emulates the physical distortion of radio waves to understand the signal propagation.

Additionally, these systems can be augmented with calibrated RF measurements using the NI Vector Signal Transceiver for characterization and compliance.
