“…Examples of this trend are the extension of conventional powertrains with start-stop systems, electrical brake energy recuperation, electrical auxiliary units, hybrid configurations of all kinds, all the way to pure battery or fuel cell powered electric vehicles. Defining the variety of electrical systems as part of the powertrain, in combination with mechanical and thermal domains, is a major challenge for the design of the overall system and the dimensioning of the individual components (Wurzenberger et al 2012a;Kastler et al 2015). The objective of system simulation is to simulate and compare topologies such as the one shown in Fig.…”

System simulation is a part of the overall field of systems engineering and provides quantitative results to verify and validate the architecture and parameters of a system under development. In the meantime, system simulation is a wellestablished activity in the automotive development area and covers a broad range of applications over the whole development process from system architecture definition, component dimensioning up to virtual testing and calibration. In all of these steps, simulation helps the systems engineer find the best choice of system architectures, evaluate the component target characteristics, define the control logic and parameters, and support the individual tests. Thanks to system simulation, proper system function can be confirmed in early phases of development, which minimizes the number of cost-intensive development loops. In addition, verification and validation and calibration tasks can be frontloaded to reduce overall development time. This chapter focuses on the setup of different physical domain models and how they are linked together. The modeling approaches of the individual domains and simulation management are discussed.
