FKFS has been working on hybrid vehicle operating strategies for almost two decades now. While the degree of freedom for conventionally-powered vehicles is essentially limited to gear selection, when different drive types are used, further questions arise about the choice of drive path and the drive power distribution. As well as minimum-CO2 coordination of the drivetrain, a central focus of our work at FKFS is to develop operating strategies for the simultaneous optimization of pollutant emissions and noise behavior (NVH) of hybrid structures. Because the energy converted from the fuel can be stored temporarily in the battery, it is possible to chronologically decouple the motor power from the currently-required drive power. This also gives rise to other opportunities for optimization using predictive cartographic information. FKFS has published a variety of papers on these topics in the course of our diverse research activities.
