Cover Story
The Road to
Zero Prototypes
by Lindsay Brooke
ADAS and HMI development are new applications for
simulation solutions.
The concept of designing, engineering and manufacturing
a new vehicle without physical prototypes is
typically viewed as either impractical or mythical. Even
as virtual development processes have become increasingly
capable, experts maintain that hard prototypes are
still needed to validate the fidelity of virtual models.
But " zero prototypes " is more than a slogan at
one of the top providers of real-time simulation and
driving simulator solutions. For VI-grade, zero prototypes
are a crusade.
" We have customer companies that are already
building their first physical prototype very, very late
in the design cycle, " noted Guido Bairati, VI-grade
managing director. " That prototype is really a pre-series
production vehicle. "
Bairati believes Darmstadt, Germany-based
VI-grade (owned since 2018 by Spectris plc), with
its many families of simulation tools, is nearing the
threshold of eliminating physical prototypes in vehicle
development as well as in ADAS, a fast-growing application.
Building a vehicle simulation model allows
engineers to do multiple runs offline on the computer.
They can identify corner cases, then evaluate those
cases on the driving simulator even before the first
prototype is built. By doing that, engineers can frontload
problems and tackle a lot of development in the
last part of the V-model (verification and validation).
" Basically you do everything earlier - and the
VI-grade managing director Guido Bairati says
simulation is moving product development from
hybrid prototypes to zero prototypes.
earlier you find issues, the easier it is to solve them, "
Bairati said in an interview with SAE Media. As soon
as hardware components - for example, a steering
system, a damper, a camera or lidar - become available,
they go into a methodology that integrates hardware-in-the
loop (HiL) testing with one of VI-grade's
driving simulators. A full, complete physical prototype
is not needed. Instead, engineers work with
what Bairati calls a " hybrid prototype " in which some
components are represented by software and some are
real hardware.
" The driving simulator is becoming basically an
