"

Without FMVSS standards to certify to...we're operating in the blind
for how to get field approval.-Keith Brandis, Volvo Trucks North America

"

A lack of regulatory action has also helped give
rise to a challenger for DSRC. Most automakers plan
to put cellular modems in vehicles, so some companies started examining cellular as an alternative to
DSRC. If support for technologies developed by the
5G Automotive Association gets a foothold in automotive, it could change the volumes of DSRC modems.
Truck companies have largely remained focused
on DSRC, which has been extensively tested. Platooning
technologists also like the low latency of DSRC. While
communication between cars and trucks brings benefits,
developers are currently more concerned with communications over the truck's CAN bus than with passenger cars.
"Trucks use a version of DSRC that's designed to
work with J1939," Brandis said. "We have demonstrated
communications between Volvo cars and trucks, but
that's not a major issue right now."

In the event of failure

Functional safety, a mainstay of vehicle design for
years, also changes for platoons. When a component or
system fails, many strategies address safety by stopping
the vehicle. In platoons, returning control to drivers
can be an effective alternative.
"Functional safety requirements increase due to
the nature of platooning," Rotz said. "A platoon operates
at following distances too close for an average human
driver to respond; therefore, in the event of a component

and transmissions.

failure, the system shall bring both vehicles to a safe
state-in other words, to a larger following [distance]
suitable for the driver. This requirement drives several
aspects of component and system design."
Connectivity brings another safety concern-
cybersecurity. Vehicles need to know that they are
indeed communicating with trucks in close proximity,
not a hacker or a truck above them on an overpass.
Vehicle systems like brakes also need to know signals
are coming from authorized modules.
"One aspect is to develop according to current
industry guidelines and best practices for addressing
cybersecurity, such as SAE J3061," Rotz said. "Another
aspect is deployment of certificates and certificate
authorities to certify the authenticity and integrity of
the communication channel. These are commonplace
for V2V deployments in industry today. Furthermore, it
is beneficial to use external services that provide threat
analysis and perform several forms of intrusion or penetration tests on the designed system. These are but a few
tools at our disposal to ensure safe communications."
Business concerns also change when convoy
vehicles aren't all in the same fleet. Lead vehicles
will create drafts that improve mileage for trailing
vehicles. It may be hard to find "leaders" if they don't
get compensation.
"Monetization will be a challenge," Gosbee said. "The
truck drafting behind the lead vehicle may not be in the
same fleet. There's potential that a trucker could be giving
a benefit to a competitor. Communications to the cloud
will change; now you're talking about handling money." ■
