One important task of electrification of vehicle powertrain is the functional integration of all new systems in respect of the performance, comfort and emission restrictions. In this particular case, starting from a mass produced vehicle platform in the small vehicle segment, the requirement was to keep the originally installed powertrain largely unchanged, but on the other hand enabling hybrid operating functions such as boosting and recuperating and additionally providing some torque vectoring features, under all relevant driving situations. The paper describes and explains the possibilities and limitations of an electrically supported four wheel drive system: first in simulation by use of a mathematical model and then, the experiences gained in the actual development of a prototype car, will be reported. A special focus will be put on the methodology of the development of a model based hybrid controller.
The paper shows how different possibilities of electrified propulsion can bring more benefit into the vehicle regarding driving comfort, driving safety and driving pleasure without additional components. Complex control functionalities of electric motors in the propulsion system and their effects on the vehicle behavior are explained. It is shown, how advanced control functions can influence steering behavior, movements in the vehicle structure and the response behavior of component operation in a positive way. The shown robust technology with the cross-linked functions is versatile with different potentials for diverse drivetrain configurations. The paper demonstrates how to let the physical propulsion system untouched and takes into account the interaction of all components of the entire vehicle. First tests, simulation and validation results are presented.This increases safety and comfort aspects but also more fun to drive and generate 'the electric smile' on the customers face.
