AutoPartsAsia | OCTOBER 2017 | 27any other system in an automotive,
there is an electronic control unit
(ECU). In Simulink he can simulate
the entire control system and if
satisfied with the performance he can
automatically generate the code using
an Embedded Coder, another product
of MathWorks.
“In Simulink, once you are satisfied
with the developed system, you can
automatically generate code using
the Embedded Coder. Then it can
be embedded in a processor that
is on the vehicle. It gets the end
C-code. Instead of someone manually
writing C-code, where there can
be so many errors. In MATLAB and
Simulink we provide all the building
blocks and a rough architecture.
Customers can customise those
into their own environment as their
vehicle architecture could vary. Wealso provide a reference model. Using
these tools they can quickly build their
own vehicle architecture. We provide
lots of basic tools in the software
itself,” he said.New Products
MathWoks releases at least two
new products every year. The latest
products are Automated Driving
System Toolbox, and Powertrain
Blockset. The Automated Driving
System Toolbox provides algorithms
and tools for designing and testing
ADAS and autonomous driving
systems. OEMs can automate
ground-truth labelling, generate
synthetic sensor data for driving
scenarios, perform multi-sensor
fusion, and design and simulate
vision systems. It supports multi-
sensor fusion development with
Kalman filters, assignment algorithms,
motion models, and a multi-object
tracking framework. Algorithms for
vision system design include lane
marker detection, vehicle detection
with machine learning, including
deep learning, and image-to-vehicle
coordinate transforms.
The Powertrain Blockset provides
fully-assembled reference application
models of automotive powertrains,
including gasoline, diesel, hybrid,
and electric systems. It provides
a standard model architecture
that can be reused throughout the
development process and can be
used for design trade-off analysis and
component sizing, control parameter
optimisation, and hardware-in-the-loop
testing. OEMs can customise models
by parameterising components in a
reference application with their own
data or by replacing a subsystem with
own model.
“Systems are getting more and more
complex. For a hybrid vehicle you
have a traditional powertrain coupled
with a battery. So, again it is multi-
domain. There are electrical systems,
mechanical systems and then you are
talking of alternate fuel, or hydrogen
based systems, and then you bring
in a different domain. MATLAB, and
Simulink, along with the model-based
design, allow you to model these
multi-domain systems. That is why our
tools are extensively used by almost
all the automotive OEMs; right from
Toyota to Fiat Chrysler, from BMW
to Tata Motors to Ashok Leyland to
Mahindra. We have a very strong
customer base in the automotive
industry,” Rao said.
MathWorks tools are very
efficient in facing the challenge ofKishore Rao
