Frankfurt am Main. Intelligent control saves energy and improves security means always anticipating what awaits us too. Communications Car-to - X makes an important contribution to future intelligent mobility , which allows the driver to look to the future bmw safety, see things that are hidden , and even poke around several corners.
BMW safety and communication
As the communication potential of Car-to - X can not be fully exploited by the massive use , the only real advantage is to be gained by investigating this technology in partnership with other partners. So , four years ago , many companies in the automotive and telecommunications bmw safety, the state government of Hesse, the city of Frankfurt and a number of universities and research institutes are recognized together to work on the project research simTD ( insurance and intelligent Mobility - Test Field Germany ).
BMW safety network
Their common goal was to test the technology Car-to - X in real traffic . Now bmw safety, the results of this project were announced in concluding presentation in Frankfurt am Main.
Car-to - X communication technology networks for the future. Communication in Car-to - X, vehicles and infrastructure are interconnected electronically bmw safety. This allows direct communication between vehicles and between vehicles and traffic infrastructure , such as traffic light signals . Communications Car-to - X is via wireless LAN or mobile network connections.

The ad - hoc communication relies on wireless broadband, which is derived from the high frequency WLAN IEEE 802.11po their G5A and allows real-time communication. The protocol is structured so that multiple users can communicate with each other in parallel. At the same time, bmw safety mobile communication networks are becoming more powerful with greater bandwidth and delay even shorter - or latency - in data transmission. As such , play an increasingly important role in communication Car-to - X , for example, as a way to supplement WLAN communications .
20 BMW cars and BMW motorcycles participated in five simTD . After four years of research, testing one of the world's largest field for communication Car-to - X is now complete. The use of more than 120 test vehicles, the technology has been tested for the first time in real traffic conditions on motorways and main roads bmw safety, as well as urban areas and around Frankfurt routes . "BMW Group was the only partner in the project to involve cars and motorcycles in the field test ," says Dr. Christoph Grote , director of research and technology of the BMW Group .
BMW safety assistant
Cross and Assistant Deputy Traffic Sign developed by the BMW Group. For the research project simTD bmw safety, BMW Group engineers focused on the development of two driver assistance systems based on communication Car-to - X : Crossing the signaling traffic assistant and assistant .
Assistant cross traffic. Only in Germany , one-third of all injury crashes occur at intersections, and other road users are registered too late or not at all. The following is an example of an everyday situation bmw safety: A pilot cross some intersections in a city or town, by buildings, trees and cars parked along the road , the view over the paths cross often prevented.
Sometimes passing traffic has priority, and often (in Germany ) vehicles on the right have priority over those on the left. It is at this point that occurs Cross Traffic Wizard bmw safety: based on data received from road users in the area of the intersection , which is capable of driving notify all potential hazards .
