Toyota and DENSO Transition Mass Production Engineering To MathWorks R2010b Release

Successful Transition Program Reinforces Commitment to MathWorks Tools for Model-Based Design and Fixed-Point Automotive Production Programs

Natick, Mass. - (1 Jun 2011)

MathWorks today announced that Toyota and DENSO CORPORATION, Toyota’s primary automotive electronics supplier, have chosen to transition their automotive mass-production programs to the MathWorks R2010b release. This release of the MATLAB and Simulink product families includes efficiency enhancements to ROM and RAM code generation for fixed-point automotive control systems that reduce mass-production costs.

The transition builds on the shared commitment of Toyota and DENSO to Model-Based Design, which incorporates technology for automatic embedded code generation. Both companies use MathWorks modeling, simulation, and code-generation products in their production software development programs for mass-production software. Adopting R2010b enables Toyota and DENSO engineers to apply Model-Based Design in current and future production vehicle programs and to use automatically generated, fixed-point production C code for complex, real-time embedded systems.

“The joint development efforts with MathWorks that began in 2003 have matured significantly over the last eight years,” said Shigeru Kuroyanagi, General Manager, Automotive Software Engineering Division, Toyota. “MathWorks continues to make advancements towards our quality-cost-delivery (QCD) initiative requirements. Their R12.1 release satisfied delivery of toolset capability and support, R2006b provided sufficient quality for production use, and the latest version, R2010b, delivers cost reduction. By using R2010b as a third-generation toolset, we can apply R2010b’s enhanced code-generation efficiency for fixed-point ECUs to deliver cost reduction for mass-production. We also expect a significant reduction in development costs through the increased use of automatic code generation for fixed-point ECUs.”

Over the last three years, MathWorks has worked closely with Toyota and DENSO to provide the advanced capabilities required in Simulink, Stateflow, and  Embedded Coder for powertrain production programs. Additionally, DENSO developed comprehensive modeling guidelines, supplemental tools, and materials to prepare Toyota and DENSO engineers for moving their production work from R2006b to R2010b.

“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 more than 15 years as part of a collaborative effort to develop the engineering tools required by the automotive industry, with the last 8 years 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.”
