Hybrid Powertrain Engineering and Driveability Evaluation with AVL-DRIVEMarket RequirementsIncreased crude oil prices and legislations have paved the way for the market introduction of Hybrid Electric Vehicles (HEV). Meanwhile, a wide selection of various hybrid configurations is on the market or under development. Customer expectations do not only concern better fuel consumption; they also apply to performance and driving enjoyment. This leads to enhanced functionality and complexity of hybrids compared to conventional powertrains. Thus, an intensive evaluation and calibration of driveability-relevant criteria is required.
AVL ApproachAVL is committed to integrating and optimizing HEV powertrains by combining its know-how in engine and transmission engineering, simulation technologies and test systems. AVL acts in very close cooperation with OEMs and hybrid component suppliers to develop hybrid-specific criteria concerning driveability. This strength is utilized to create an objective driveability evaluation. Various assessments and benchmarks have been carried out to validate the requirements.
AVL Offer PackageAVL provides a tool for objective analysis of driveability in HEV powertrains. AVL-DRIVE for Hybrids is based on the conventional version of AVL-DRIVE and allows a hybrid-specific vehicle evaluation. Additionally AVL offers the Hybrid Development Platform (HDP) (a unique platform for virtual test driving with real hybrid components in the loop), HEV engineering, testing and calibration.
