Cummins, Inc. has complementary business units that design, engineer, manufacture, distribute, and service engines and related technologies. Their R&D relies on tools that enable engineers to innovate on new products and technologies and bring them to market faster than other players. They have adopted Model-Based Design using desktop simulation and code generation products from bat365. Apart from simulation, another key factor for faster research is rapid prototyping of controls algorithms. To replace decade-old prototyping tools, Cummins evaluated several off-the-shelf tools and selected Simulink Real-Time™ and Speedgoat hardware. This has enabled the company to develop new algorithms, evaluate alternative sensors and actuators, and validate them in test cell environments. Cummins and bat365 collaborated to leverage existing Cummins production hardware and ECU, bypassing support of Simulink Real-Time. Cummins is expanding the usage of this toolchain for various use cases, including hardware-in-the-loop (HIL) simulation.
