This thesis deals with the description, implementation and application of a numeric simulation approach for efficient energy demand analysis of vehicles while (driving. The simulation approach uses in automotive industry established highly specialized simulation environments and combines them for energy demand analyses. In order to couple simulation environments a simulation platform is created. It is based on MATLAB/Simulink and is designed as an open system. This means, the simulation platform uses - depending on the simulation target - always only a customized range of highly specialized and optimal simulation environments. Currently the simulation platform contains the simulation environments MATLAB/Simulink, CATIA V5, SIMPACK and the Microsoft Office products ACCESS 2010 and EXCEL 2010. The functionality of the simulation platform can be upgraded at any time by involving further simulation environments and can be expanded according to individual needs. On the one hand the coupling of simulation environments already introduced which is used here can reduce the effort for development. At the same time it creates new challenges in the development process. One of the advantages of the chosen simulation approach is the absence of new simulation environments which exclusively focus on energy demand analyses. Another advantage emerges form the possibility to use existing simulation models from other disciplines - for example the classic longitudinal, lateral and vertical driving dynamic development of vehicles. This particularly reduces the effort during model preparation. The key challenges while implementing and applying the simulation platform are the communication options and limitations of the individual simulation environments as well as the data consistency of the simulation models. The realized simulation platform uses available interfaces for the communication between the simulation environments. The data consistency is ensured by integration of large databases. The data-based approach enables for example the automated parameterization of simulation models. Additional synergies are created by the organization of vehicle and vehicle component models in expandable modular systems. Depending on the target of simulation vehicle and vehicle component models - which are available in the modular systems - can be freely scaled and combined. This means, simulation models can be set up, further developed and used depending on individual needs and development progress. Potential application possibilities start with basic calculations and simulation models of lowest detail level. These are necessary for analysis of potential at the start of every vehicle and vehicle component development. They include simulations with modular expendable simulation models of higher detail level for the phase of concept selection. Finally, they also allow the analysis of detailed effects and complex interactions during an advanced stage of development using simulation models with high level of detail.
