Our objectives are:

• Develop and integrate hybrid components within the flexible simulation framework and enable studies of new hybrid architectures.

• Explore optimal configurations (component location and matching) and energy conversion options for high performance, efficient and clean propulsion of military and dual-use vehicles.
  
• Extend the choice of architectures to include a systematic investigation of the power-split system.

In addition to developing advanced models, simulations and methodologies for optimal design and control, we plan to assist the Army in evaluating hybrid propulsion options for the High Mobility Multipurpose Wheeled Vehicle (HMMWV) and its future replacement Joint Light Tactical Vehicle (JLTV). A synergistic collaboration with an industry partner Bosch-Rexroth will enable transitioning of basic research and quantification of the benefits that can be expected from a patented hydraulic infinitely variable transmission (IVT) with/without energy storage. Future direction will include consideration of electric alternatives and on-board power generation.
