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

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.”

complete design and

verification during this

phase. No delay due

to waiting.

Using MBD

Traditional MethodGreen: Function Design

Orange: Detailed Design

Pink: Implementation

Blue: Verification

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.”
