rivien is a lot of things we make
adventure vehicles
but i think more importantly we're here
to
change the way that people's
relationship is to transportation
to the outdoors to energy use in general
the rot is the beginning of the
adventure for arabian this is our first
vehicles to market it's our first
flagship product
[Music]
when you
take a clean sheet platform like the r1
platform is
you can create kind of anything so it
gives us a lot of freedom to basically
integrate the latest and greatest
technology and really offer the best
experience to our customers
we have an incredibly powerful compute
platform immediately i wanted to get
unreal engine whether it's in the driver
display or in the center display we want
to be able to render things in unique
ways that you haven't seen inside of
automobiles the sensor view of the world
around you really has to build trust
with the end user and from a user
experience standpoint it's job one job
two is to tell me you can't change lanes
right now because there's a car right
beside you when we evaluated unreal
engine we compare that to other
solutions the results showed was unreal
engine was the most performant and it
had the best graphics that had the
highest quality so it was an easy
decision
hmi is literally the human machine
interface it's how we as people interact
with a product like an automobile so
here are the challenges with hmi safety
so you don't want to distract people you
don't want to give them too much
information too little information there
is occlusion what happens with your
steering wheel what happens with your
hands when your hands cover the screen
what happens when your seat is low what
happens when your seat is high there's
glare what happens when the sunlight
hits a certain angle does it shine into
your eyes so you just can't start with a
graphic design and say this is really
cool and then make it a driving
interface it's so much more complex than
that we love working with partners who
can iterate with us while obviously
keeping a very high bar in terms of
safety reliability and quality and it
took a lot of iteration how much was too
much are we overwarning people
really quickly we dialed it in using
unreal engine the fact that we could
bring designers and engineers into the
same platform we'll talk about some
feedback one day and the next day we
have a change ready that was just so
exciting that you go from like concept
to trying it out in a day or two
when it comes to the content coming out
of unreal engine those cars need to
match reality as close as possible to
build trust with the user because unreal
could handle all the polygons we just
kept the original data and not having to
rebuild that from scratch that was a
huge time saver it also made the vehicle
really accurate and so it's not a
simulation of one of our vehicles it's
actually our vehicle that's running
there in your driver display in real
time the r1t on screen actually has a
budget of about 500 000 polygons pretty
crazy that we can get away with it on
embedded hardware
i think the the main advantage that
unreal engine brought us is really
velocity from a development standpoint i
mean once we have the three-year
presentation of the car the speed of
development really allows us to enable
more and more use cases in a very fast
way one example that we iterated on in
blueprints a lot was the lanes
drawing a spline on screen that
represents the road curvature there's a
lot of math involved to convert the data
that you receive from the cameras into
the engine we had to go through multiple
iterations until we got it right we
couldn't have figured that out if we
weren't using blueprints to prototype
this is really
the first use case of android engine we
have the advantage of having a deep
over-the-air update solution so there's
more and more exciting updates coming
whether it's in the driver display or in
the center display for safety for
entertainment all of that headroom that
unreal affords us is a real gift i'm
super proud with what the team has done
we're not only thinking about the auto
as it is today we're thinking about the
future the stuff that we are now
imagining it's something that you will
have never seen in a vehicle before and
that's exciting to me
