Hybrid powertrains are also being used increasingly in the commercial-vehicle segment to achieve maximum system efficiency. Particularly in urban transport with its many accelerating and braking cycles, hybrid powertrains can help to cut fuel consumption and CO2 emissions by recuperating braking energy. As one of the leading system integrators for hybrid vehicles, we can provide comprehensive expertise in all of the disciplines involved and offer our clients the full range of hybrid development services.
Topology (serial, parallel, power-split or plug-in hybrid), configuration of the energy storage system (electric, hydraulic, mechanical) and associated components are key aspects in developing and defining concepts for a hybrid powertrain. This makes simulating the hybrid powertrain one of the focal aspects in developing hybrid commercial vehicles. Our efficient simulation tools enable us to find the ideal solution for the particular vehicle operating strategy and energy management system. This includes the hybrid manager for synchronizing combustion engine, electric motor (or alternative drive), transmission and powertrain, battery management as well as optimizing driving strategies (gear selection, load point, battery state of charge etc.).
