C2X communication uses IEEE802.11p, a wireless standard designed specifically for automotive applications. This allows cars to communicate with each other (car-to-car) as well as with intelligent traffic infrastructure (car-to-infrastructure) around them. The newly developed C2X platform from NXP and Cohda actually sees around corners in order to recognize traffic blocks or risks before they are visible to the human eye. Drivers therefore receive early warnings of cars hidden from sight behind trucks or approaching from around corners. Other use cases are warnings about emergency vehicles and traffic jams, or traffic light signals allowing drivers to adjust their speed and optimize driving.
The C2X platform is able to meet the requirements of the automotive industry: reliable signal reception for fast-moving objects even in difficult surroundings, cost-efficient design, and flexible programming. It uses Cohda’s Advanced IEEE 802.11p radio and is based on NXP’s multi-standard radio reception platform. NXP’s expertise as global leader in car entertainment semiconductors and Cohda’s patented reception algorithms are critical factors for successful development.
The C2X demo is one of several connected mobility demos which NXP is presenting during Automotive Week 2011, from May 14 to 22, 2011 in Eindhoven, Netherlands. As project leader of the Dutch SPITS research project (SPITS: Strategic Platform for Intelligent Transport Systems), NXP is a major contributor to Automotive Week. For a whole week the Brainport Region is the international stage for the latest technological developments in the automotive field. Industry, Dutch government and research institutes are joining forces with the theme of “Building the Future in Mobility.” Other demonstrations from NXP at Automotive Week 2011 include intelligent traffic data analysis from the in-vehicle networks, as well as emergency and breakdown calls based on NXP’s telematics module, ATOP.
Kurt Sievers, senior vice president and general manager of the Automotive business at NXP Semiconductors, explains: “Connecting the car to the environment demands in-depth expertise in secure connectivity, Software-Defined Radio architectures, and telematics. These technologies are at the very heart of NXP’s automotive portfolio. NXP has therefore set a high priority on gaining the pole position in connected mobility. The SPITS project has been extremely valuable for us as it brought experts and research partners from all parts of the value chain together all working towards the same goal: efficient and sustainable mobility solutions.”
