Powertrain Blockset contains a range of ready-to use reference application models of petrol, diesel, hybrid, and electric powertrains. It includes a component library for simulating engine subsystems, transmission assemblies, traction motors, battery packs, and controllers. The software also includes a dynamometer model for virtual testing.

It provides a standard model architecture that can be reused throughout the development process and can be used for design tradeoff analysis and component sizing, control parameter optimization, and hardware-in-the-loop (HiL) testing. Engineering teams can customize models by parameterizing components in a reference application with their own data or by replacing a subsystem with their own model.

The simulation software also includes reference applications for common electrified powertrains such as electric and multimode hybrid electric. These reference applications are open so the designer can configure and parameterize the electrified powertrain components, including motors, generators, and energy storage.

For system and control development, including HIL testing, these blocks provide a balance of realistic closed-loop behaviour and simulation speed and the model can be customised for more detailed analyses, for example, including the effects of power electronics switching by using blocks from Simscape Power Systems. The system designer can also predict electrical efficiencies and losses using blocks from Simscape Electronics.
