The connected car of the future will have more options than
ever, expanding beyond basic
infotainment and navigation
systems to offer the latest in
safety features, and (in the-not-
too-distant future) autonomous
driving . The requirement for more
sensors and antennas to deliver
connectivity is seemingly at odds
with another requirement of auto
manufacturers—fewer cables and
connectors that cause noise and
vibrations, while being complicated
and expensive to install . In
today’s connected cars, antennas
and electronics are increasingly
being forced in closer proximity.
What does that mean for design
For a modern car, electronics
represent a little more than 30
percent of the vehicle’s total
costs, and that percentage is
expected to rise . The more
electronics a vehicle deploys,
the greater need for electrical
power, system components,
and need to interconnect those
system components . Electronic
connections (be it the power supply
or control wiring harness), digital
communications connections, or
radio frequency (RF) interfaces
add complexity, cost, and weight .
Automotive designers spend
considerable effort to minimize
these factors .
Consumer expectations are such
that even base model vehicles are
now expected to have features
like smartphone connectivity via
Bluetooth, entertainment, and
safety systems like the Event
Data Recorder or European eCall .
Hence, significant design efforts are
required in this area every time for
all models .
Old cars dealt with the power
and control needs of facets like
power windows and seats, using
very complicated discrete wiring
systems . Their weight and cost kept
these features in premium vehicles .
