Dig into wide-ranging technical topics about modern vehicle technology with industry leaders, hosted by Sanjay Khatri, Head of Product Marketing, Sonatus.
Welcome to another episode of
the Driving Innovation Podcast.
Modern vehicles are
amazing feats of design and
engineering, but they're
also increasingly complex to
develop, test and validate.
Today, we're diving into how one
of the world's leading automakers
is revamping its pre-production
validation process through a
data driven and AI-aided
approach to simplify that
complexity, gain efficiency
and ultimately save costs.
I'm your host, Sanjay Khatri,
and I'm thrilled to introduce
our guest, Sarah Dorey,
Senior Engineer for e-Planning,
Coding and Cybersecurity at
the Nissan Technical Center Europe.
Sarah is here to discuss how
the center is solving major
validation challenges and
accelerating its vehicle
development programs with the
help of Sonatus Collector AI
and AI Technician.
We'll explore the power of
event driven data collection,
the insights unlocked by
connecting data across
complex vehicle subsystems,
and how an iterative closed
loop workflow is fundamentally
changing how they conduct
root cause analysis.
Sarah, thanks for joining
me on this podcast.
Hi, great to meet you. It's
lovely to be here again.
Thank you. Yeah, so
let's get right into it.
Your organization is at the
center of Nissan's vehicle
development program
for, I should say,
award winning and popular
models like the Nissan LEAF and
Juke.
By the way, congratulations on Nissan
LEAF getting all sorts of awards.
What were the validation
challenges your teams were
running into that made you
look for a different approach?
Yeah, thank you.
Great question, because it's something
that's been challenging us and many
OEMs through the
development phase.
We tend to find difficulties
when it comes to root cause
investigation in all of
our standard developments.
It's nothing unusual
within the industry,
but with the distances where
our manufacturing plant
is at two R&D centers in Europe,
one in the UK and one in Spain,
gathering data can
be really difficult.
You have to be on the spot or at
least have somebody with the skills,
knowledge and capability in the
right place at the right time.
And that's not always the case.
Quite often you're
gathering data, you go back,
you analyze the data.
And even after that analysis,
you want to do some more
data collection to really dig deep
into the data, really analyze
what ECU is having what
problem with what scenario
or what CAN connection.
So more data logs are required,
which if you've already left
the site is a bit of a problem.
Also, it comes to our
development cycle and we're
adding vehicles go down
the production line,
we have problems come
up as they're produced.
The traditional model is that the
data loggers go on as the
twelve volt battery
is connected.
But we don't find out what's
on that data logger until it
reaches the end of the
line, somebody collects it,
they upload the data and then
notifies us that it's available
in the cloud so that we can
go into that data again.
So this kind of slows down
the investigation process
and makes it quite lengthy.
We want to speed up
with what we're doing.
We have such great products.
We want to be able to get them out
to our customers a lot quicker.
The products are a lot
more complex as well.
So there's a lot of development
concerns that we need
to have a look at,
which are standard concerns.
But we want to make sure that the
customer doesn't get to see these.
The software is so complex.
You've got cybersecurity
on top of that.
There's a lot to dig into and
we want to make sure that by
the time we release
that product,
that the customer is getting the best
of what our products can deliver.
So it's really been
able to speed it up and
reinforce the quality that
we offer our customers.
Yeah, so I hear you
describing something
which maybe I can characterize
it as digitalizing or
virtualizing the process
so that it's more dynamic,
it's more real time without
having to wait on assets,
wait on test vehicles, do a lot of
sort of manual transfers and so forth.
So I mean, it's reducing a lot
of the friction in that process.
So you've adopted a more sort of
digitalized and AI enabled
workflow with Collector AI and
AI Technician. What sorts
of results have you seen?
Yeah, it's really
quite promising.
We're obviously going through our
proof of concept project at the moment,
but the engineers are really
enthusiastic about the
opportunities.
As I said, traditionally we're having
to travel to go and collect data.
With the remote
deployment of policies,
we don't need to
be able to do that.
And then with the redeployment
of policies, again,
it's very quick and very easy.
We can see results
really quickly.
When we then turn around
that data into AI Technician,
then we can start to go
through the FTA (fault tree
analysis) really quickly.
We can start using
our experience and our
education to be able to ask
the questions that go into the data
that AI Technician connects
all the dots for us.
So we're not having to sift
through different SharePoints
and different files to pull all
that knowledge together or go
and speak to people across the
business because we've pooled
all of our Nissan knowledge
and using AI Technician,
we can bring it all together.
So it's really exciting that the
speed that we can be able to do this.
And we need all of our
engineers still within our
business to be able to
make these decisions,
but they can at least do
it quicker with more access to
data and real
reliable data as well.
So it's a real bonus for us.
So I hear you saying,
number one, it allows
your engineers to work on
vehicles without having
physical access to vehicles.
So you sort of remove
that dependency of
contention with resources in
terms of your test vehicles.
And then the other one is being
able to sort of dynamically do
things potentially even in a
test drive, I would assume,
so that you're not having to kind
of bring the vehicle back, refit it,
adjust the loggers
that are in the
vehicle and so forth.
So is that how you
would characterize it?
And how is
that helping sort of,
you talked about kind of a
global team with multiple
sites, presuming you have
interactions with folks in
Japan as well. How is that
all helping you collectively?
Yeah, it gives us a
lot of flexibility and agility to
react to situations.
This ability to remotely deploy
the policies means that we can
have a car going around to test
track in Barcelona, but
I can be accessing it
here my home.
I can be doing it
from the office.
Somebody from Japan could be
checking the dashboard data as well.
So this one car and one
data set with access for
all really opens up
the opportunities for us to
go quite wide across our test
fleet when we're testing in a
way that we haven't
necessarily done before.
Normally, test cars are allocated
to a particular function and a
particular test.
So it really does mean that
we have more resources for all of
the engineers to be able to
use across the globe if we're
adding this remote access.
So that's really quite exciting.
Let's talk about the analysis.
As I mentioned early
on, vehicles are
amazing these days, including
the ones that I mentioned.
But they're also very
complex, a lot of electronics,
a lot of what I would call sort
of cross domain dependencies,
features span
multiple subsystems.
And oftentimes
what I would assume
is that connecting a lot
of those dots across those
subsystems can be challenging,
especially when
you're looking at
one particular data silo.
How has AI Technician, in
conjunction with Collector AI,
helped your engineers connect
the dots across these domains?
And what sort of insights and
time savings has that unlocked?
The engineers, their
skills are exceptional,
but they can't be an expert
in absolutely every ECU and
every system across
such complex vehicles.
And as I said before,
once you add cybersecurity
on top of that,
then it really does add a new
level to what we're working on.
To bring in AI Technician that
links with the Nissan Knowledge
Data Lake, AI Technician can
bring that knowledge together.
It can make everybody an expert.
You don't have to be waiting for an
email from somebody for a few days.
We've essentially gone
for if we're root cause
investigation on a
particular technical
concern, we can see
where the opportunity is.
During our proof of
concept delivery,
we've seen that we can go from
two weeks to two days for a
root cause investigation.
And that's massive.
But because it breaks
through that complexity,
because it can join all of
those dots for our engineers,
that's really exciting.
I absolutely love how it comes
back with my Nissan knowledge
because I'm an engineer.
I don't trust anybody.
If you're going to give me
an answer, I want proof.
And you've got to go really
deep to make me believe it. And
the Technician Solution
does It
comes back to me
in my own language.
It starts quoting documents
at me that I probably wrote at
some point and it goes into
all of that depth that actually
says, this is why you
should believe me.
But it also tells me why
it discounted other things.
That feels like a conversation
that I'm having with our engineers.
And that therefore makes me
believe that it's really gone
into the depth of the knowledge
that we have at Nissan and we
have many years to be able
to call on to give me a good
quality response back so that
engineers go into that decision
making process with a real
rich knowledge backing up
their decision making, which
is where we want to be.
That's what we do. But
now it's time consuming.
With the Sonatus AI we can get
that through that so much quicker.
Interesting.
Yeah, I like how it's
it's augmenting the work
that engineers are doing
by giving them almost an
assistant on the side who can
go out and get that information
that they may not
have access to,
or they're not sort of
inherently knowledgeable about.
It sounds to me also that
there's some sort of of an
iterative process, right?
So rather than sort of a static
linear, you get some data,
you do some analysis,
you go back and test,
and it's sort of a
sequential process.
Can you describe to me some
of the sort of the closed loop
workflow aspects of how
sort of this dynamic data,
the analysis of AI Technician,
and then potentially kind of
going back and iterating on it?
Can you give me a
little bit of insight in
how prevalent something like
that is and how much of that is
actually helping you?
Yeah, and engineers are the kids
that always grew up saying, "Why".
Why, why does this happen?
So whenever a problem comes up,
a concern needs investigating,
that's what they're going to do.
You give me some data, but then
I've got more whys to go into.
We set our policies on that.
It can be quite broad,
so we can just ask it to look
for any DTCs that come up
on an ECU.
And it will flag that and it will
collect that data automatically.
That's really cool.
But what we can also do is
pick up CAN signals that we
specifically want to target.
So if I know I'm
looking for something
related to that is
on the CAN network,
then I can set that and it
can bring that back to me as well.
So I can have these
simultaneous data collections
to really cover everything
that I'm looking to do.
It'll upload all of those
data logs into AWS for me.
So then it sat up
there into the AWS
with our Nissan knowledge and
they sit there side by side.
And with AI Technician, we
can then start interrogating that.
The cool bit after that is
that we can take that FTA
knowledge, all of that "why",
and put it back into
a policy and redeploy.
So from our user interface
that here in my garden
or the guys in Spain
or Japan globally,
we can just redeploy that.
And we can keep
going on this loop.
With the closed loop system,
then we've got that
additional safety.
And Nissan knowledge isn't
sat in somebody else's cloud.
So there's no vulnerability
when it comes to that element.
So we can feel quite secure that all
of our knowledge is held together,
whilst being able to really
deep dive into our knowledge.
So it's really cool, really.
You talked a little bit about those
better alignment across global teams.
As you expand these tools to
programs like the upcoming
Juke and the LEAF Models,
what do you see as the next
step in the smart testing AI
assisted validation?
Yeah, thank you.
It's a real opportunity
now to take more of our
digitalization work and feed that
back into this whole process.
And in the proof of concept,
we can see where the
advantages are, and off we go.
We can then get those
recommendations from the [AI]
Technician that give
us other opportunities,
whether it's seeing trends
across the business where our
fleet is flagging
certain anomalies.
Or if we're just looking
to secure that data across our
whole fleet, can do one vehicle,
we can do many vehicles.
So we can then begin to look where
we can do simultaneous testing.
So it might be me
needing a data set.
It might be two or three of
my colleagues that also need a
data set from the same car.
We can set our policies
onto that one vehicle.
We don't need three
different vehicles.
So that's where we've been
able to look at that reduction
in the test vehicles.
The cost is high, they're
prototype vehicles.
So any advantage for us to be
able to do that is always going
to be a win.
Well, has been really
helpful, Sarah.
And I really want
to thank you for
sharing your precious time.
I know you're very busy,
but this has really
been helpful.
And I've learned a lot.
I thought I knew a lot about
project that we have going on,
but I've also certainly learned
a lot and you've added a lot
more color to it.
So I really want to
thank you for joining us.
Thank you. Thanks for having me.
It's always great to
chat with you guys.
That brings us to the end of
another insightful episode of the
Driving Innovation Podcast.
We've seen how Nissan Technical
Center Europe with the help of
Sonatus Collector AI and
AI Technician is fundamentally
changing pre-production
testing and validation.
By leveraging event driven data
collection and closed loop AI
assisted workflows,
Nissan Europe is accelerating
vehicle development,
reducing costs, and achieving
better global team alignment.
A huge thanks to Sarah Dorey
for sharing how this smart
testing approach is shaping the future
of models like the Juke and the LEAF,
And we look forward to bringing
you more of what's next in the
evolution of AI assisted
vehicle development and
validation in future episodes.
