10 Proven in the Harshest Environments
Applying Ethernet in a Mixed Architecture
To handle increased data demands and high-speed
connectivity, sophisticated network infrastructure
is needed. Controller Area Network (CAN) bus
architectures, which typically manage speeds up to
500kbps, have been the stalwart backbone for most
heavy-duty vehicles' communication networks for a
few decades. However, the data bandwidth required
for advanced vehicle functionality and automated
features for safety and productivity is too great to
be served by CAN alone.

Harsh Environments

ustomers are demanding functionality
that automates or enhances operational
tasks to increase driver productivity and
safety and, in many cases, reduce total cost
of ownership. Basic customer requirements
for vehicles now include automatic adaptive
braking and steering, onboard diagnostics,
vehicle-to-vehicle (V2V) and vehicle-to-
infrastructure (V2I) communication, and
cameras that give drivers a 360-degree view of
their environment.
These features require large amounts of data
to be transmitted at high speeds. As engineers
design new models to meet these customer
demands, the challenge is to ensure signal
integrity and data transmission in the trucking
and off-highway industries' harsh environment.
