V2V tested between two Audi cars with relative speed of 500 km/h

Audi AG has successfully tested vehicle-to-vehicle (V2V) communications technology designed by NXP and Cohda Wireless in Germany. In a test scenario, two vehicles fitted with v2v technology were approaching each other at a relative speed of 500 km/h, and they could share the data in real-time with 2 km distance between two vehicles. NXP claims its RoadLINK chipset cut reaction time and communicated potential hazards and safety-critical scenarios significantly faster than conventional wireless technology.

This test used intelligent roof antenna made by another automotive component expert Delphi. NXP hardware secure element was also used to protect the communications from manipulation and unauthorized tracking or data access.

NXP Semiconductors N.V. has expanded its investment in Cohda Wireless. Cohda Wireless and NXP are working on adoption of V2X (vehicle-to-vehicle and vehicle-to-infrastructure) technology. This technology includes security layer where safety, traffic warning/ data is exchanged between vehicles wirelessly in real-time. The data such as this involves huge amount of security protection and also reliable transmission of data in absolute real-time. Lot of such data can be passed down from vehicle to vehicle in a busy traffic. V2V, V2X communication reduces the burden on autonomous driving systems. Even in the case of non-autonomous driving systems, v2x communication ensures smooth flow of traffic, safety, and improves driving experience.

NXP Semiconductors's RoadLINK with Cohda MAC/PHY firmware along with NXP hardware security module protect consumers and the industry against illegal hacking and cyber attacks.

NXP says "leading car brands have recognized the performance of the combined NXP/Cohda RoadLINK technology. It will be used, along with Cohda’s V2X software stacks and applications, in Delphi’s V2X communications platform for cars entering the market in less than two years from now."
