The central to intelligent driving, which is synonymous with free energy-efficient and safe driving, is forward thinking. To help drivers plan alee, vehicles from the BMW Group are already fitted with a big number of sensors designed to better safety, comfort and efficiency. Often, however, these sensors have only a limited predictive capability or "horizon". "Auto-to-ten" communication extends this horizon significantly, and will in time to come allow drivers to "meet" long distances ahead, into areas currently hidden from view, and even around non just i but many corners.

Auto-to-x communication means electronic networking of vehicles and roadside infrastructure, with the aim of exchanging data direct both between road users and between road users and roadside infrastructure such every bit traffic lights. Auto-to-x advice is a comprehensive communication network which whatever road user can take part in. Motorcar-to-10 communication usually operates via WLAN or mobile phone connections. For standard automotive application, car-to-x communication at nowadays uses high-speed WLAN networking based on the high-frequency WLAN IEEE802.11p/ G5A standard, which is designed to allow existent-time communication.

The protocol allows big numbers of participants to communicate simultaneously without interference. At the same fourth dimension the functioning of mobile phone networks is improving steadily, with an increase in bandwidth and a reduction in data lag – the so-chosen latency times. Therefore, this type of medium, too, is becoming increasingly important for car-to-motorcar communication, for case as a complement to direct communication via WLAN.

Connectivity brings added value.

Integrated and continued vehicle functions are nothing new within the BMW Grouping. Connectivity for infotainment applications already made its debut in the 1990s with BMW ConnectedDrive. For some years, the focus of development work in the BMW Group has been shifting increasingly towards integrated and connected comfort and, in detail, rubber functions. Here, motorcar-to-x advice opens upward completely new potential. In the effect of a hazard, extensive connectivity between vehicles allows oncoming and following traffic to exist given advance warning of potential dangers, and therefore to react appropriately and in expert fourth dimension.

But warnings are simply one possible apply of this communication platform. Since infrastructure data, too – for example well-nigh traffic light phases – tin be integrated into this advice system, data is bachelor which allows drivers to easily adapt their driving style for even greater efficiency, thereby significantly reducing vehicle emissions. This technology therefore offers new solutions non only for proactive rubber and blow prevention but too for intelligent energy management.

"The more than data I have almost the rest of my journey – for example, if I know in advance when traffic lights volition alter, or if I know that an accident has just happened further along the route – the more promptly I can react, which means I have less stress and can either avoid hazardous situations altogether or at to the lowest degree reduce the take a chance." (Karl-Ernst Steinberg, Caput of Information and Communication Technologies at BMW Grouping Inquiry and Engineering science).
In combination with existing vehicle sensors, car-to-x communication provides a valuable starting point or enhancement for a broad range of BMW ConnectedDrive driver assistance and information systems of the time to come. These technologies, combined with the commuter's own input, create an extremely high-performance macrosystem capable of ensuring a prophylactic and efficient journeying from kickoff to finish.
