Key topics: Car-to-X communication

Car-to-X technology allows information to be sent to other vehicles over a long distance in order to give them early warning, for example, of a hazardous situation. Mercedes-Benz is the first manufacturer to offer Car-to-X communication in standard production vehicles.
Accident site around the next bend? A sudden traffic jam at a roadworks? These nasty surprises are factored out of the equation if the approaching motorist is given an accurate warning in plenty of time. Vehicles will be able to do this in future by warning other road users automatically once they themselves have registered a hazard. This is the principle of Car-to-X communication, which Mercedes-Benz has co-initiated, becoming the world's first car manufacturer to introduce it in series production vehicles.
Car-to-X technology significantly extends the previous range of vehicle sensors, such as radar or camera systems. It allows information on dangerous situations automatically detected in the vehicle or manually reported by the driver to be sent to other vehicles, making it possible to "see" around corners or through obstacles. Consequently, information on potential hazards on the road can be sent to drivers at an early stage so that they can prepare for them and avoid critical situations altogether – such as those caused by suddenly changing weather conditions or stationary recovery vehicles at the side of the road.
As well as being able to receive hazard warnings, every vehicle equipped with Car-to-X technology can also send such warnings to other road users. As a result of seamless integration into the existing vehicle systems, Mercedes-Benz passenger cars are able to automatically detect a variety of sources of danger, such as a breakdown or heavy rain. The driver does not need to do anything.
For Car-to-X communication, Mercedes-Benz uses the vehicle's integrated mobile-phone technology, as, thanks to its widespread use, it can unleash the potential of Car-to-X technology in the shortest time. In the Daimler Vehicle Backend server, the data are aggregated, checked for plausibility and forwarded to other similarly equipped vehicles in the relevant vicinity.
The system is designed to use third-party information, too. Since autumn 2015, for example, the German state of Hesse has provided information on mobile roadworks. The inclusion of additional data sources is in preparation.
Car-to-X communication operates in the background and does not distract the driver's attention from the road. It provides the driver with early and accurate information in safety-critical situations. Car-to-X technology can therefore be seamlessly integrated into the "Mercedes-Benz Intelligent Drive" strategy.
By becoming the world's first manufacturer to introduce Car-to-X technology in series production vehicles, Mercedes-Benz is once again reaffirming its role as a safety pioneer, and demonstrating that its engineers are continuing to work consistently to bring to the roads innovations that can be used not only by our customers but also by other road users.
