TECHNICAL TRENDS
Council members seek consensus on
next generation tractor-trailer interface
THE GROWING DATA DEMANDS OF ADVANCING TECHNOLOGY
DRIVE NEW COMMUNICATION SOLUTIONS.
By Robert Braswell
It's served the trucking industry well, but most
industry experts agree the time has come for
the venerable SAE J560 seven-pin tractor-trailer
connector to be replaced with a new solution that
will better accommodate the growing power and
data needs of 21st century trucking. The tough
question is, what's next?
While this robust, tried-and-true 12-volt connector
is utilized ubiquitously throughout the North
American market, the power and data demands
of each generation of technology advancement
have pushed the limits of what can be done with
this connection. Multi-voltage requirements, solar
installations, electric drive and regenerative braking
axles, advanced driver assistance systems
(ADAS) and automated driving systems' (ADS) -
and the host of sensors, emitters, and cameras that
support them - mean the need for a new connector
standard is increasingly necessary and urgent.
ATA's Technology & Maintenance Council (TMC)
recently released a position paper from its S.7
Trailers, Bodies & Material Handling Study Group
regarding the tractor-trailer electrical architecture
of the future. The paper - TMC PP 2023-1: Design
Recommendations for Next Generation Trailer
Electrical Architecture - has several recommendations
for smart trailers and hopes that trailer
manufacturers will use these as a road map for
the development of technology that will access the
robustness of suppliers' offerings. TMC specifically
wants to ensure that new interface solution will
be backward compatible as well.
S.7's Next Generation Trailer Electrical Architecture
Task Force identified several principles
that guided their research. First, that the
current electrical architecture is inadequate for
the future. Second, that trailer tracking is well
established in the industry and is only growing.
Third, that electric-powered refrigeration may
require off-board charging of trailers. Fourth,
that new and safer vehicles pursued by original
equipment manufacturers (OEMs) require additional
information and control. Fifth, that many
companies have proposed new architecture for
trailers. Sixth, TMC established similar issues
regarding tractor data networks in the 1980s.
Seventh, fleet input is critical for more efficient
and reliable electrical information on trailers.
Finally, that collaboration is anticipated with
other TMC Study Groups.
» TMC Connector Task Force members are asked
to evaluate how well each prototype would
provide the desired technical performance
criteria.
TMC
Based on these principles, the Task Force is
working with TMCs S.1 Electrical Study Group
and its Next Generation Tractor-Trailer Interface
Task Force to obtain input from tractor manufacturers
on future needs for safer vehicles; obtain
input from fleet/equipment users on the future of
electrical wiring; review proposals from manufacturers;
and develop initial expectations for a
recommended practice from TMC.
TMC has its own thoughts on how the
industry could improve the safety,
efficiency, and reliability of freight.
Smart trailer expectations include
the right for users to repair their own
equipment; the preference of patentfree
solutions from industry groups;
the preference of global non-proprietary
solutions; the consideration of
forward/backward compatibility; the
importance of safety; the need to standardize
on a single telematics device
when untethered; better
support
for doubles and triples; the need for
upgradable software; the fair sharing
of data ownership and electronic
documentation; the necessity of highspeed
connections for smart trailers;
the focus on cybersecurity due to
increasing connectivity of devices; the
consideration of future power connections;
and the consideration of installation,
maintenance, and inspection in
factories and in the aftermarket.
During TMC's 2023 Annual Meeting
SEPTEMBER 17-21, 2023 | CLEVELAND, OHIO | HUNTINGTON CONVENTION CENTER
2308FMS_TMC.indd 1
32 Fleet Maintenance | July 2023
in Orlando earlier this year, the S.1 Task
Force presented eight competing designs
for what the future tractor-trailer
interface could be. The intention of the
construction of the recommendations
was to describe an " ideal " interface and
to not be constrained by existing art.
