Model-based Development and Calibration of Hybrid Powertrains

Hybrid vehicles are characterized by a combination of mechanical, electrical and control components. The complexity of this mechatronic system requires new methods and tools for a successful development of new hybrid vehicle concepts. It is now possible to accomplish certain tasks earlier in the development projects using virtual prototypes of the powertrain components and the vehicle. The process called “frontloading” integrates simulation, optimization and validation in earlier development phases of a vehicle and prevents from having cost intense problems in later development phases. Besides the reduction of emissions and fuel consumption also the subjective impression of the vehicle driveability are main goals for the optimization of hybrid powertrains. The paper gives an overview of the new Hybrid Development Platform from AVL and shows that the consequent introduction and realization of integrated development and testing solutions including the efficient and comprehensive optimization and validation of the vehicle characteristics on test beds can contribute to successful hybrid vehicles in the global market.
