Case Study: Delphi halves transmission modeling time with MathWorks (Simulink & Simscape Driveline)

Delphi Cuts Transmission Modeling Time by 50%

Delphi Powertrain Systems faced the challenge of developing production-intent controls for diverse six-, seven-, and eight-speed transmissions, each with unique mechanical architectures and ever-shorter shift events. To shorten development cycles and adapt quickly to OEM specs, Delphi partnered with MathWorks and used its Model-Based Design tools, including MATLAB, Simulink, Stateflow, and Simscape Driveline, to model mechanics and develop control algorithms.

Using MathWorks tools, Delphi rapidly assembled physical transmission models, automatically generated real-time code with Simulink Coder, and validated controllers via hardware-in-the-loop tests (using Fixed-Point Designer for numeric issues and OPAL-RT test hardware). The result: transmission modeling time was cut by about 50% (a six-speed model built in six weeks instead of months), earlier algorithm validation, and a unified, reusable tool chain that lets Delphi support multiple customers more quickly.
