Toyota Uses MathWorks Tools to Increase Quality, Reduce Costs, and Speed Time to Market of New Vehicles Challenge Speed up design, increase quality, and reduce R&D costs by finding an alternative to traditional design methods Solution Use 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. Akira Ohata Toyota Link to user story 4
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 Link to user story 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 Corporation A Toyota engine. Simscape modeling helps Toyota ensure more precise control of sophisticated engine components such as turbochargers and after-treatment systems 5
