摘要

With trends towards increasing electrification and popularity of SUVs (Sport Utility Vehicles), electric SUVs with new design features lead to a need for reassessment of the trade-off between vehicle dynamics, ride comfort and rollover stability. In order to increase efficiency, this trade-off has to be assessed in the early stage of vehicle development, within a virtual environment. In this paper a model from former work is extended and the simulation accuracy is improved. Subsequently, the differences between conventional and battery electric SUVs are described. Especially the influence of the battery, e.g. changes of CoG (Center of Gravity) and inertial properties, is discussed in detail. Through analysis in simulation, the effects of various properties of electric SUVs at full vehicle level are analyzed. At subsystem level, an example of design trade-off is studied in more detail and conclusions, as well as an outlook onto further work are derived.
