Autonomous Vehicle Engineering - November 2021 - 26

People/Ideas
Electric and autonomous trucks will have a lot more electronic controllers and
networks. As the vehicle gets more complicated, the attack surface increases.
companies have spent the past 10 or 15 years working
on. " For quite some time, perception will be the playground
for other players who have been working on it
for [many years] and have developed their skills and
knowledge, " Navistar's Gangopadhyay said. " Everything
else in the vehicle, even the motion control, and of
course, body control, brake systems, those are traditional
vehicle systems. Once you draw the line at motion
control, everything beyond that - perception and
maybe planning - is where partners will play a big role. "
Clear and constant communication between all
the different parties is extremely important, Chen said.
" The perception system doesn't fail on its own; the
truck doesn't fail on its own, " he said. " Failures occur at
the interfaces typically, where if you don't have a clearly
defined interface control document, or expectations
are not set correctly, that's when the ball is dropped. "
Cyber defense challenges
Electrification and autonomy are driving increased
vehicle complexity, which will undoubtedly complicate
efforts to combat cyberattacks. " I'd say it's going to go
to a whole new level, especially through your wireless-communication
vulnerabilities, " said Mark Pope,
product specialist at DG Technologies and moderator of
a Cybersecurity panel at the SAE COMVEC conference.
Electric and autonomous trucks will have a lot
Oshkosh will manufacture the U.S. Postal Service's next
generation of postal delivery vehicles, which potentially
could benefit from increased levels of autonomy.
Collaboration and partnerships are another strategy
increasingly being employed to accelerate AV development.
" Just the sheer complexity of the problem leads to
the fact that none of the OEMs can solve it alone, " said
Peter Waeltermann, president of dSpace and moderator
of a COMVEC session on validating ADAS and AVs.
PACCAR's " go-to-market plan " is to collaborate
with autonomy developer Aurora. " What we concluded
in making that decision is that we want to leverage
what we do best - building and validating trucks that
are going to perform well, " Olsen said. " Developing
autonomous driving stacks is not what we do best. "
Truck OEMs do not want to invest millions of
dollars re-creating what many self-driving technology
more electronic controllers and networks. " There are
more operating systems involved probably than there
have been in the past; therefore, there's more variety of
networks, " said Chris York, director of electronic system
cybersecurity at Cummins. " So, we might have CAN and
CAN FD and Ethernet or LIN all turning up on a vehicle.
As the vehicle gets more complicated, it does increase the
attack surface and the old adage that 'security is only as
strong as its weakest link' is very true. "
Another challenge is that many autonomous system
providers are in startup mode, so the products are not
necessarily mature - these companies still are at the stage
of trying to make their systems work. " I hope that they're
considering cybersecurity at the forefront and don't try
to bolt-on a solution after the fact, " said Dr. Jeremy Daily,
associate professor of systems engineering at Colorado
State University. " But my fear is that somebody's going to
underspecify a requirement for cybersecurity on those
