Marben, a provider of V2X software solutions, and Rolling Wireless, a supplier of network access devices (NADs) to the automotive industry, have completed a proof of concept (PoC) showcasing V2X Day 1 applications for automotive telematics.
The PoC used cellular V2X (C-V2X) communication technology to facilitate the exchange of information between vehicles and their surroundings, focusing on critical situational awareness for improved road safety.
The collaboration involved implementing Marben’s C-V2X software solutions on Rolling Wireless V2X hardware to demonstrate an optimized architecture for V2X applications. The PoC utilized the Rolling Wireless RX113A V2X module connected to a Rolling Wireless 5G network access device (NAD), integrating the C-V2X direct communications (PC5) modem.
The NAD served as the application processor and GNSS resources, akin to a telematics control unit (TCU) architecture. Marben’s V2X communication stack and Day 1 applications were successfully integrated and executed on the NAD’s application processor.
The PoC looked at two typical V2X Day 1 use cases: forward collision warning and emergency vehicle approaching. The forward collision warning alerts the vehicle to an impending collision with a stopped or slow-moving vehicle ahead, enabling the driver to take timely action. Similarly, the emergency vehicle approaching feature notifies the vehicle about an approaching emergency vehicle, allowing the driver to clear the road preemptively before the siren or light bar becomes audible or visible.
Andreas Kohn, chief operating officer at Rolling Wireless, said, “Improved connectivity between vehicles and other entities will provide substantial safety and efficiency benefits. Day 1 applications are also laying the groundwork for the future transition to fully autonomous driving.”
Vish Emani, MD at Marben, added, “This successful proof of concept exemplifies the capabilities and performance of Marben V2X stack and applications, and we are excited to prove how seamlessly they integrate with today’s state-of-the-art hardware for automotive telematics.”
