Case Study: Mitsuba Corporation cuts reversing wiper development from 16 weeks to 3 weeks with MathWorks

Mitsuba Accelerates Development of Reversing Wiper System

Mitsuba Corporation needed to accelerate development of an innovative reversing wiper system whose embedded controller required more complex controls than a conventional wiper. Their prior paper-based requirements and handwritten-code workflow forced most debugging and tuning on hardware, causing late defect discovery, significant rework, and long development cycles. Mitsuba turned to MathWorks for a model-based development approach using MathWorks tools such as Simulink, Simscape Multibody, Stateflow, and Embedded Coder.

Using MathWorks tools, Mitsuba modeled, simulated, verified, and generated production C code (including software-in-the-loop, processor-in-the-loop, and hardware-in-the-loop testing), standardized practices through training and guidelines, and reused plant and control models across projects. MathWorks-enabled development cut a specific feature’s timeline from 16 weeks to 3 weeks, reduced design review time and paper documentation by 90%, minimized rework through earlier verification, and supported a product now shipping 20,000–30,000 units per month.
