MathWorks Provides Software Development Support for Toyota and DENSO

12/16/2003 - The MathWorks announced it has signed an agreement with Toyota and DENSO, Toyota’s primary automotive supplier, to provide extended support services for use in their software development for automotive production programs. This agreement provides Toyota and DENSO with focused technical support services that will enable the companies to utilize automatic embedded code generation technology to accelerate their production software processes. Specifically, Toyota and DENSO will use The MathWorks simulation, modeling, and code generation products in a number of their software development for production programs, including powertrain control and other electronics control units.

“Toyota has a ‘kaizen’ way of always pursuing evolution and innovation, and challenging the improvement,” said Kazuhiko Hayashi, General Manager, Integrated System Planning Department from Toyota. “I think that The MathWorks and Cybernet Systems have understood our ‘kaizen’ way, and then provided these extended support services, which we expect will continue for a long time. We have various efforts underway to promote more efficient vehicle development. Toyota believes that this agreement will contribute a great deal to these efforts.”

The agreement is a four-party contract that includes Cybernet Systems Company of Tokyo, Japan, the MathWorks distributor for Japan. Cybernet will provide local, front-line support to Toyota and DENSO, with direct assistance from The MathWorks. The agreement provides extended support services for MATLAB®, Simulink®, Stateflow®, and other key control design products. Of particular significance is the capability provided by Real-Time Workshop® Embedded Coder, which is used to generate, test, and deploy production C code for complex, real-time embedded systems.

“DENSO is improving our production processes using advanced software tools,” said Shinji Shirasaki, Director, Electronics Product Division, from DENSO. “We expect that our consistent use of these tools will allow us to accelerate our ability to bring DENSO products to the market more quickly. The commitment of The MathWorks to responsive service of its products that are used in our production process is a key component of this agreement, which gives us the confidence to use automatic code generation in our production design stage. By partnering with both MathWorks and Toyota, we expect to be able to move our products from the advanced design stage to the production design stage to installation in delivered vehicles much more quickly.”

“We are pleased to be working with Toyota and DENSO in extending our tools and support services from their advanced design departments into the production design process,” said Richard Rovner, Vice President of Marketing at The MathWorks. “Our goal is to combine our expertise in control system design with the extended support required to assist Toyota and DENSO to use our tools throughout their advanced design and production design processes. This agreement is a major step in our long-term strategic commitment to the use of our products in a production environment.”

Every major automotive OEM and supplier in the world uses products from The MathWorks throughout the design, development, analysis, calibration, and test processes. The Company’s model-based design tools enable automotive engineers to address the challenges of vehicle-level modeling, rapid prototyping, real-time simulation, and production code generation in a productive and efficient manner.
