"Südwestpresse Ulm" reports on 5. April 2016 (in German):
A "caravan" of three Mercedes Benz Actros trucks is on the way from Stuttgart to Rotterdam. Plattoning is considered as a means to reduce CO2 emissions and fuel consumption. This test ride is part of the European Truck Platooning Challenge 2016 initiative. So far only Daimler Trucks has a world-wide official approval for platooning on ordinary roads. The trucks can run at a bumper-to-bumper distance of only 15 meters which is enabled by wireless communications allowing reduction of reaction-time (e.g. upon breaking) from about 1,4 seconds (human) to less than 0,1 seconds.
A radio technology suited for platooning is the IEEE 802.11 @ 5,9 GHz (ISO 21215 - currently under revision at ISO) technology developed for Cooperative Intelligent Transport Systems (C-ITS). As this 5,9 GHz technology is needed for many other C-ITS applications, development of next generations complementary radio technologies already started, e.g. infrared (ISO 21214) and millimeterwave technologies in the band 63 GHz to 64 GHz. Initial investigations in millimeterwave communications for ITS started about two decades ago; ISO recently launched two new projects aiming on standards for the physical layer (ISO 21216-1) and the data link layer (ISO 21216-2) to be used in the context of an ITS station (ISO 21217).
Dr. Fischer from ESF GmbH is engaged in suitable radio technologies since the early 1990s. At Telefunken Systemtechnik GmbH in Ulm, he contributed to the SMILER project, and was project coordinator of the COMIS project.
Please contact Dr. Fischer for support in your C-ITS project.
