and decipher the information or not. Others say,
vehicle owners - be it an owner-operator or a fleet
- will need to be proactive in gaining clarity and
transparency from vehicle manufacturers on the
information transmitted from the truck.
"Companies increasingly want to internalize
the ownership, control, and know-how around
their [vehicles'] data," says CSS Electronics' Falch.
"This is driven by security concerns, as well as a
drive towards 'digital transformation.' As [fleets] grow more
digitally savvy, they realize
the importance of fully owning
their data - and they build
capabilities to support this."
Those capabilities may also
include in-house, custom-built
telematics, instead of relying
on third-party telematics
service providers, adds Falch.
If anything, it will continue to
drive a desire to have access to
this information.
"A standardized J1939 protocol will be a key prerequisite
for this, and we expect to see
these companies increasingly
flex their procurement muscles
to force OEMs to either adhere
to standards or provide insight
into proprietary decoding
rules," Falch adds.
The evolution will continue
with diagnostic systems as
telematics allow for the automatic access and transmission
of vehicle data and fault codes,
without the need to physically
connect a scan tool.
"Scan tools, telematics
systems, electronic logging
devices (ELDs), etc., all basically do the same thing; they
monitor and provide viewing
of the vehicle data bus for
needed information such as
faults detected, speed, engine
rpm, temperatures, etc.," says
NEXIQ Technologies' Kotenko.
"Scan tool products may have
the ability to take this further
with added information to
assist the technician."
IoSiX's Vogt provides additional examples of where
standardized data can help
with the vehicle's operation
and analysis, especially as it
relates to telematics and vehicle operation analysis.
"We extract information
like seatbelts, and wipers, and
doors, and transmissions, and
infotainment, climate control,
and headlights - things that
the driver can interact with,"
explains Vogt. In addition, he
says data on a vehicle's operation, with information such as
fuel consumption and system

temperatures, are also easy to access and can
provide [insight] to improve upon current operation of the vehicle. "For example, looking at fuel
consumption over time, you can derive the load
on the vehicle... or, if there [are] any efficiency
issues aerodynamically or from a rolling resistance standpoint on the vehicle."
As the commercial vehicle industry moves
forward with more computerized vehicle systems,

it will create additional challenges for these
systems to transfer data and maintain security.
"Protocol improvements and vehicle network
improvements will continue to address information needs and create added challenges,"
says NEXIQ Technologies' Kotenko. "Automotive
vehicles will also drive the need for change as
data will be even more plentiful and required for
decision-making purposes."
