The integration of electric components into the automotive powertrain enables completely new powertrain architectures and configurations to be designed. These components also enable new powertrain functions such as engine start-stop operation or recuperative braking with new interfaces to the driver and other vehicle systems such as the braking system. Advanced driver assistant systems (ADAS) are either under development or already on the market and require new interfaces to the vehicle. In summary, these trends lead to a high diversity of powertrain systems in terms of hardware, controls, and software functionality. This in turn results in higher powertrain system complexity and increased overall development effort. This chapter outlines the most relevant powertrain architectures along with their corresponding powertrain functions and powertrain elements. An overview of other non-powertrain vehicle systems shows the interlinking of the powertrain with them. A summary of development challenges resulting from this powertrain system diversity is given.
