Daimler Trucks has just announced the U.S.’ first
autonomous truck, the Freightliner Inspiration. The truck has been granted a
license for road use in Nevada, allowing Daimler to further test the truck’s
systems and abilities to self-drive along the highway.
This isn’t Daimler’s first autonomous truck,
however. 2014 Saw the automaker demonstrate the Mercedes-Benz Future Truck 2025
as it drove along the A14 autobahn near Magdeburg, Germany. It’s technology
from that truck that has crossed the Atlantic – and through some rigorous
recalibration for U.S. roads – and into the Freightliner Inspiration. It’s
called Highway Pilot.
Daimler says the autonomous truck is designed to
help ease the stress on long-haul drivers, as well as reduce traffic congestion
and improve the truck’s overall fuel efficiency thanks to the
computer-controlled driving. The company makes it clear the truck isn’t a
replacement for drivers, saying the self-driving aspect is relegated to highway
use and the driver is needed for rural and urban roads.
In fact, Daimler sees the driver’s roll actually
becoming more important. During highway sprints, drivers can attend to other
tasks, or even become “transport managers” – making the trucking career more
attractive.
Though Daimler makes no reference to the
Freightliner Inspiration’s powerplant, the truck is based off the standard
Freightliner Cascadia Evolution. Under its hood lies a Detroit Diesel DD15,
inline six-cylinder turbodiesel that displaces a massive 14.8 liters. The
engine comes in various tunes, but can make up to 505 horsepower and 1,750
pound-feet of torque. The engine uses Mercedes’ BlueTec aftertreatment system
to keep exhaust emissions down. A Jake brake helps bring things to a relatively
quick stop.
Power is routed through the optional Detroit DT12
Automated Manual Transmission that features 12 forward speeds. The transmission
features the traditional inner workings of a manual transmission, but its
clutch and shift lever are computer controlled to promote easy driving and
increased efficiency. The tranny also includes Skip Shift, which allows the
transmission to skip gears when the extra torque isn’t needed, along with
eCoast, a function that disengages the transmission during coasting that is
designed to save fuel.
