Abstract

The following article describes the development and evaluation of alternative concepts to improve the energy budget of an existing vehicle by using a total vehicle simulation. Based on extensive measurements, the behavior and all relevant elements of the vehicle have been analyzed, modeled and validated. The simulation results enable an integral quantification of improvement potential. One of the essential results is the influence of hybrid driving functions on the thermal behavior of the vehicle as well as the impact on the fuel consumption. By dint of simulation experiments, the maximum fuel saving potential has been calculated for various driving cycles, control strategies and configurations.
