[ SAFETY & TECHNOLOGY ]
T
he computerization of commercial vehicle powertrains
has revolutionized the way they operate
today. This constantly evolving vehicle system
continues to integrate technology, giving engine
designers and maintenance professionals unprecedented
power to fine-tune and even micromanage
virtually every aspect of how a vehicle operates.
Small computers, called electronic control
modules (ECMs), can manage everything from the
spray shape of fuel emitted from a fuel injector
to precisely when and how that fuel is ignited, to
automated manual transmissions (AMTs) skipping
gears to ensure optimal fuel economy, and even
acceleration in different operating conditions.
Coupled with this explosion of engine management
software and ECMs has been a revolution in
wireless and cellular communication capabilities.
Using these systems, designers of everything from
smartphones, tablets, laptops, and even powertrain
systems can now receive software updates
from virtually anywhere with good Wi-Fi or
cellular service. Increasingly, truck and engine
OEMs are using this over-the-air (OTA) update
technology to perform all sorts of system updates
and checks-tasks that not long ago would have
required bringing a truck into a dealership and
plugging in a computer to obtain the same results.
" The concept of OTA is rather new for the trucking
industry, even though it has been a technology
used by suppliers of different industries for some
time now, " said Bruno Gattamorta, chief commercial
officer for diagnostic and maintenance solution
provider Cojali. " We can find an example in
telecom providers who for years have been using
this for deploying the firmware and file packages
with a better level of coverage-mobile devices
connected to an established Wi-Fi connection. And
now, thanks to the new 4G/LTE and 5G networks,
the paradigm has changed, and the Internet of
Things (IoT) allows us to connect multiple devices
with a robust and fast bandwidth. "
This has led to smarter trucks capable of higher
levels of communication among vendors, carriers,
and customers.
" Our latest generation of Volvo trucks are like
iPhones on wheels, " explained Ashley Murickan,
product marketing manager, connectivity and
OTA features, Volvo Trucks North America. " The
extensive OTE connectivity features dealers,
customers, and drivers have access to have a huge
positive impact on the truck's productivity and
efficiency, enabling remote software updates and
remote change of parameter settings to optimize
the truck according to its assignment. "
The change started as OEMs and technology
providers began adding more sophisticated
components to manage all the new telematics
and engine data coming from the trucks, resulting
in more efficiency and visibility on the maintenance
side. Lee Lackey, product manager at
