Vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communications, collectively referred as vehicle-to-everything (V2X), is a wireless technology aimed at enabling data exchanges between a vehicle and its surroundings.
V2X technology is based on 5.9 GHz dedicated short-range communications, a Wi-Fi derivative specifically defined for fast-moving objects and enabling the establishment of a reliable radio link, even in non-line-of-sight conditions.
By sharing data, such as their position and speed, to surrounding vehicles and infrastructures, V2X systems improve driver awareness of upcoming potential dangers and dramatically improve collision avoidance, and heavily reduce fatalities and injury severity. In addition, the technology will enhance traffic efficiency by providing warnings for upcoming traffic congestions, proposing alternative routes and ensuring eco-friendly driving, reducing CO2 emissions through adaptive cruise control and a smarter transportation management.
ST has a long-term partnership with Autotalks – a V2X chipset market pioneer – for the co-development of open-market optimized V2X chipsets meeting the quality standards required by the Automotive industry.
