Toyota and DENSO Transition Mass Production Engineering to MATLAB R2015a Release

Successful Transition Program Reinforces Commitment for reducing the Model-Based Design running cost and model-based incremental development

Tokyo, Japan - (12 Oct 2015)

MathWorks today announced that Toyota and DENSO CORPORATION, Toyota’s primary automotive electronics supplier, have chosen to transition their automotive mass-production programs from MathWorks R2010b to R2015a release. This release of the MATLAB and Simulink product families includes a wide range of productivity enhancements, including in the areas of automatic code generation and verification.

Toyota and DENSO both use MathWorks modeling, simulation and C code generation products in their ECU production software development. With the spread of Model-Based Design, both companies have been able to realize benefits such as;
- Enhancement of Productivity: enhance the productivity of operation by improving workflow efficiency and product usability in every MBD process.
- Incremental development adoption: support incremental development from existing models, which engineers spent more than 90% of their daily work in MBD.
- Continuous feature improvement: improved features of key MBD products such as Embedded Coder for automatic C code generation, and Simulink Design Verifier™ for enhanced model verification capabilities

During the past five years, MathWorks has improved product usability such as improving the Simulink and Stateflow editor to enable productivity improvements of Model-Based Design. The R2015a MATLAB and Simulink products have improved usability with an enhanced editor, increased performance with fast simulation restart capability, added incremental development support with the Model Slicer feature of Simulink Design Verifier, and simulation testing with Simulink Test.

Using R2015a as a common platform enables Toyota and DENSO engineers to realize efficiency and productivity benefits of model based incremental development in current and future production vehicle development.

According to Shigeru Kuroyanagi, head of Toyota’s motor control system infrastructure development group, "Toyota, Denso and MathWorks began cooperative development activities in 2003 to address the industry’s need in the vehicle development field. Using R2010b as a third-generation toolset, we were able to apply automatic code-generation for mass production, and with R2015a we are able to further improve incremental development and design verification. Having the enhanced feature for vehicle development, the result is a positive impact on our productivity."

“Toyota and DENSO’s commitment to Model-Based Design shows how MathWorks software continues to be used by the automotive industry around the world for product design and development,” said Andy Grace, vice president of engineering for design automation at MathWorks. “We have been building our close relationship with Toyota and DENSO for nearly 20 years as part of a collaborative effort to develop the engineering tools required by the automotive industry. During the past 12 years, we’ve focused on meeting specific needs for production use at Toyota and DENSO. We are pleased that our efforts to create high-quality software for mass-production usage have been recognized by Toyota and DENSO.”
