Develop Safer Cars using Cellular Vehicle-to-Everything (C-V2X) Communication

What if vehicles could communicate driver intent to each other and help reduce non-impaired crashes? That soon could become a reality using 5G wireless cellular technology to provide high bandwidth and low latency communication for Vehicle-to-Vehicle (V2V) and Vehicle-to-Infrastructure (V2I) communications. We recently announced a collaboration with S.E.A., one of our Alliance Partners, to help maximize the full potential of connected and intelligent mobility. 


Our software-defined approach will help automotive manufacturers and suppliers validate the safety and efficiency of vehicles, with the flexibility to adapt to the latest technology with minimum hardware and software changes.


Eliminate 80 percent of non-impaired crashes


In a 2016 study, the National Highway Traffic Safety Administration (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. 


Investing in cellular communication


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.

“Vehicles equipped with V2X technology can give drivers and autonomous systems more time to react to dangerous situations,” said Gerd Schmitz, PhD, CEO of S.E.A. Datentechnik GmbH. “With S.E.A.’s long history of bringing new technologies to market, we recognized that research teams need to quickly understand the functionality and validate performance in a reliable and repeatable environment. Road tests are valuable, however, proving performance in the lab helps teams iterate faster and have higher confidence in the device operation under a broader set of scenarios, including hard-to-reproduce corner cases.”


The new C-V2X solution combines software from S.E.A. GmbH, with our 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 solution includes pre-compiled drive scenarios like 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.


With changing standards and new business models, engineers developing the next generation of mobility must balance scalability and time to market. The new C-V2X solution provides both a higher level starting point to help demonstrate early success and the flexibility of the NI platform to help ensure that these teams can adapt to market requirements.
