Mercedes Tests Safety on Wintry Roads Using Car-to-X Communication

Car-to-X technology– communication between vehicles and the transport infrastructure– significantly extends the coverage of onboard sensors such as radar or camera systems, as the sensors of other vehicles are used in addition.

Mercedes-Benz has been involved in research projects on car-to-X technology for more than ten years. Now the company has announced that in the coming winter, in cooperation with the district of Zollernalb, it will test how safety on wintry roads and the efficiency of municipal winter services can be improved with car-to-X communication.

For the pilot tests, Mercedes-Benz passenger cars equipped with car-to-X technology, whose owners have activated the Live Traffic Service, will provide the necessary data. Once the 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.”

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.
