Daimler is testing connected trucks in platooning operations on public roads in the US. Daimler Trucks North America (DTNA) has received the permission for this from the regional regulatory body Oregon Department of Transportation (ODOT).
In truck platooning, connectivity and automated driving improve safety within the vehicle convoys, support drivers and enhance efficiency through closer distances between the connected trucks. To digitally connect its Freightliner New Cascadia in the current tests in the US, Daimler combines connectivity with automated driving. Wi-Fi-based vehicle-to-vehicle communication (V2V) interacts with Freightliners Detroit Assurance 4.0 driver assistance systems featuring Adaptive Cruise Control, Lane Departure Assist, and Active Brake Assist.
This technology offers fuel savings to the customer when two or more Freightliner trucks closely follow each other, lowering aerodynamic drag and adding safety, because V2V reaction times have dropped to about 0.2 or 0.3 seconds – while humans normally can respond not faster than one second. In the future automated and connected braking between the lead vehicle and follower will prevent accidents.
