Mack Trucks is adding a dynamic steering option to its Anthem models starting
in June, giving drivers a little boost in driving efficiency.
Mack
Command Steer uses an electric motor connected to the existing hydraulic
steering to reduce driver efforts to steer the truck by up 85%. It also reduces
muscle fatigue by up to 30% and will assist in correcting the truck’s path when
needed, said Stu Russoli, Mack highway product manager.
“[With Mack
Command Steer] you can drive very confidently in an uneven ground situation,”
he said during a press conference at the Technology & Maintenance Council
annual meeting in Atlanta on Feb. 25.
The
technology, which will be optional equipment only on the Anthem model at this
point, utilizes sensors and the truck’s ECU to observe and analyze over 2,000
parameters per second to make decisions on when to help. Command Steer’s motor
then applies needed torque to keep the truck on the desired path.
It
autocorrects back to zero after the assistance is no longer required.
“The
additional torque, or steering force, provided by Mack Command Steer means
drivers no longer have to ‘fight the wheel’ while driving on poor roads or in
difficult weather conditions,” Russoli said. “This helps drivers maintain
greater control and keep their focus on what’s ahead, enhancing safety for
everyone on the road.”
Russoli
said Mack Command Steer will operate when driving on uneven roads, over
potholes or other disruptions on the vehicle’s path, and when blowouts occur.
The result is less strain on the driver.
“Even
with the all-day comfort provided by the Mack Anthem model’s ergonomic
interior, driving a heavy-duty truck remains a highly physical task,” Russoli
said. “With Mack Command Steer, we’re improving safety and productivity as well
as helping to protect the truck’s most valuable asset – the
driver.”
Mack also
announced that the day cab version of the Anthem is now certified by the U.S.
Environmental Protection Agency’s SmartWay program. The sleeper version is also
SmartWay-certified.
To achieve
SmartWay certification, Mack Anthem day cab models must be spec’d with roof
fairings and side shields, chassis fairings and an aerodynamic bumper option.
In addition, low rolling resistance SmartWay-certified tires are required. All
SmartWay-certified Mack Anthem models feature a SmartWay logo on the doorjamb.
Last week,
Mack announced capabilities that will allow drivers to decide when over-the-air
updates are made. When a parameter change is required, the Mack Uptime Center
sends the download to the truck and the driver initiates the download.
“It takes
the necessity of talking to an agent out of the picture, so you can do it at
your convenience,” Russoli said.
The average
download takes less than 15 minutes, he said.
