HEV (Hybrid Electric Vehicle ) technology will be one essential element of future mobility to reduce fuel consumption and emissions. The key enablers for hybrid technology during the last decade were improvements of the battery, the power electronics and the e-motor. Combustion engine technology as well has made significant development steps. The challenges are now to identify optimal system designs and to integrate them successfully with respect to mechanical, electrical and thermal interfaces. It is also necessary to balance the achievable benefits with required effort and related costs. This paper presents a combined 'Design of Experiments' and simulation approach towards system optimality. Design as well as control parameters are taken into account. The interactions of optimization and integration are discussed, indicating the challenges of system integration. It is demonstrated, that necessary tools and processes are in place to support the development of complex hybrid systems.A complete system approach is required when designing a hybrid electric vehicle in order make the most out of this promising technology. This system approach is represented by the utilization of sophisticated CAE (Computer Aided Engineering) technologies to identify trade-off relations and to find improved solutions under fixed performance and cost targets. Such an advanced engineering technique is e.g. the 'Design of experiments' approach which is used to reduce the number of general system simulation runs. Successful hybrid electric vehicle integration has to merge many individual components into a customer safe and properly operating vehicle. The successful system integration of the hybrid electric vehicle powertrain requires extensive expertise in a wide range of vehicle related technologies. The challenges of hybrid vehicle system integration are packaging, cooling and safety of system as well as the individual components. Although the optimization and integration work is complex, a proven tool chain is available to solve all challenges and find custom specific cost effective solutions.
