In the coming winter, in cooperation with the district of Zollernalb, Mercedes-Benz will test how safety on wintry roads and the efficiency of municipal winter services can be improved with car-to-X communication. Car-to-X is the term used to describe communication between vehicles and the transport infrastructure. Mercedes-Benz passenger cars equipped with car-to-X technology, whose owners have activated the Live Traffic Service, will provide the necessary data for the pilot tests. Once the ESP® or ABS sensors of these vehicles have recognised slippery road conditions, this information including the GPS data is sent to the Daimler Vehicle Backend in real time, using the mobile radio network. This anonymised information is displayed on digital maps in the two road maintenance depots of the Zollernalb district in real time. In the future this will make it possible to deploy the winter service more effectively and optimise the use of de-icing salt.
In the next steps it will be possible to include public service vehicles, e.g. police cars, as well as vehicle fleets. The pilot test will start in January 2020 and continue until the end of winter. The Zollernalb district is in the administrative region of Tübingen in Baden-Württemberg and has around 190,000 inhabitants, many of whom are commuters.
“With car-to-X functions we can improve safety in various driving situations,” says Michael Hafner, Head of Driving Technologies and Automated Driving at Daimler AG. “This is because thanks to seamless integration of the car-to-X system into the vehicle systems, Mercedes-Benz passenger cars can automatically detect different hazards such as slippery roads.” Car-to-X technology significantly extends the coverage of onboard sensors such as radar or camera systems, as the sensors of other vehicles are used in addition. This enables a vehicle to look around the next corner, so to speak. In addition to improving traffic safety, the technology in the pilot project could also contribute to environmental protection, as less de-icing salt is used thanks to targeted application.
Mercedes-Benz already introduced mobile networking in 2013, establishing a technology that allows danger warnings to be transmitted and received. Car-to-X communication has been installed as standard in combination with navigation systems since 2016 – first in the E-Class and now in all Mercedes-Benz vehicles – and is available after activation by the user. To use the “Car-to-X” service the customer must also hold a Mercedes me connect account. Only then are data registered in the vehicle, and the vehicle-related car-to-X data are sent to the backend where they are anonymised. In addition, Mercedes-Benz drivers can simply object to their data being shared for the purpose of a resale to third parties via their user accounts on the Mercedes me Portal.
