Toyota Uses MathWorks Tools to Increase
Quality, Reduce Costs, and Speed Time to
Market of New Vehicles
ChallengeSpeed up design, increase quality, and reduce R&D
costs by finding an alternative to traditional design methods
SolutionUse MathWorks tools for control design to prototype,
model, test, and refine control strategies in an integrated
design environment
Results Deliver a better product to market faster — and at a
lower cost
Reduce time to embedded code
Forge a pathway to innovation
“MATLAB, Simulink, and
Stateflow… have become the de
facto standard at Toyota for
simulation, data processing, and
controls design. It would be
impossible to list all of the
applications for these tools at
Toyota.”

Toyota Front-Loads Development of Engine
Control system Using Comprehensive
Engine Models and SIL+M
Challenge
Accelerate the development of complex engine
control system software
Solution
Develop a comprehensive engine model and combine
it with SIL+M testing to frontload the development
process
Results Comprehensive engine model developed
Designs verified early in development
Difficult-to-test conditions simulated
“Simscape enables us to create a
comprehensive model of the engine
appropriate for our design tasks that
is easily understood by all teams.
Closed-loop simulations of the ECU
and engine performed in Simulink,
completed as early as possible, are
essential to our front-loaded
development process.”
Dr. Hisahiro Ito, Toyota Motor

helps Toyota ensure more precise control
of sophisticated engine components such
as turbochargers and after-treatment
systems

Nissan Develops Emission Reduction
System for Mass-Production Vehicles
ChallengeDesign an emission reduction system certified by the
California Air Resources Board (CARB) for the Partial Zero
Emission Vehicle (PZEV) Standard
SolutionUse MathWorks tools for Model-Based Design to design
an emission reduction system that was certified by CARB
for the PZEV standard
Results Development time reduced by 50%
Environmental Protection Agency award received
Number of sensors reduced
“Model-Based Design with
MATLAB and Simulink is fully
proven and indispensable to our
engineering process, and gives us
an edge over our competition.”

Source of savings for OEM/Suppliers
- Reduced number of design iterations
- Increased spec quality
- Automation in verification, code generation, documentation

Mazda Speeds Next-Generation Engine
Development of SKYACTIV TECHNOLOGY
ChallengeOptimize the efficiency of SKYACTIV engines while
meeting strict emissions standards worldwide
SolutionUse Simulink and Model-Based Calibration Toolbox to
accelerate the generation and development of optimal
calibration settings, ECU-embeddable models, and
engine models for HIL simulation
Results Engine calibration workload minimized
Model complexity cut in half
Model accuracy improved
“Model-Based Calibration Toolbox not
only enabled us to identify optimal
calibration settings for the SKYACTIV-
D engine, it greatly reduced the
engineering effort required. The
models it generated accelerated
control logic development, provided
valuable insights, and made it easy to
try new ideas.”
