The impetus is provided by the Army’s and TARDEC’s emphasis on Vehicle Power and Energy systems. It’s driven by the need for fuel efficient tactical vehicles operating in the modern battlefield where endurance and resilience is one of the key parameters. In order to assure the technological advantage while maintaining the cost effectiveness of the future combat vehicles the cutting edge technology has to be deployed. An analysis of the novel hybrid propulsion systems can identify those opportunities, preselect the candidate vehicle configurations and accelerate their development.
The specific goals of this task are to:
- Develop a unified hybrid electric vehicle simulation framework for a series hybrid electric vehicle to be shared across the board. Including physics-based control oriented electric motor model for next-generation military medium trucks.
- Continue collaboration with the Prof. Hofmann (UM) and integrate computationally-efficient Finite-Element based models of Electric Machines into the Series-HEV simulation.
- Optimize electric motor sizing and design based on efficiency and hot-spot temperature predictions from the scalable physics-based e-motor model under real-world driving conditions.
- Investigate the impact of a demanding military vehicle driving missions on component duty cycles critical for new hybrid architectures control and design decisions
- Support the effort of Prof. Wagner (CU) in component thermal modeling and cooling system analysis. Integrate selected electrified accessories loads into the Vehicle Power and Energy System.
- Develop advanced supervisory control algorithms using approaches based on policy optimization and principles of self-learning. Enable optimization with multiple objectives.
