Thrust Area 4: Advanced and Hybrid Powertrains
Internal Combustion Engine & Fuels

Projects presenting:
1. Fuel Surrogates Studies and their Relation to Advanced Engine and Vehicle Development
Dr. André Boehman, Professor of Mechanical Engineering, University of Michigan

        The pursuit of effective surrogate fuel mixtures remains an important task for engine and fuels researchers. In this presentation, we will survey some recent efforts to improve the surrogate formulation for describing the combustion of JP-8 fuels. Also, other recent surrogates and fuel composition studies will be surveyed. Then the presentation will cover the role that these surrogates studies played in the recent DOE-funded "SuperTruck" program, in the development of an engine concept to achieve 55% BTE. Finally, the presentation will briefly highlight some accomplishments of the Volvo SuperTruck team.

2. Thermal Barrier Coatings for Reduction of Cooling Loads in Military Vehicles (project link)
Dr. Marcis Jansons, Associate Professor of Mechanical Engineering, Wayne State University

        Significant under-armor volume of a military vehicle is devoted to the thermal management system comprising ballistic grilles, fans, ductwork and radiators. Reductions in cooling load are therefore sought to make greater under-armor volume available for mission-critical sub-systems or crew and to improve mobility and fuel efficiency by diminishing vehicle weight. While the commercial automotive sector has recently implemented thermal barrier coatings to increase efficiency, TBCs have military applications as a means of re-distributing energy from the cooling load to engine exhaust. Titanium-based coatings applied with a novel aqueous electro-deposition process show promise in overcoming the durability issues of previously researched materials. This presentation will introduce a simulation and experiment-based project that evaluates durability and thermal shock response of TiO2-based and other potential TBCs, and examines their thermal properties and in-cylinder behavior using optical diagnostic techniques.

Thrust Area 4: Advanced and Hybrid Powertrains

Projects presenting:
1. A Smart Thermal Bus for Ground Vehicle Cooling Applications (project link)
Dr. John Wagner, Professor of Mechanical Engineering, Clemson University
Dr. Richard Miller, Associate Professor of Mechanical Engineering, Clemson University

        Designing an efficient cooling system with low power consumption is of high interest in the automotive engineering community. Heat generated due to the propulsion system and the on-board electronics in ground vehicles must be dissipated to avoid exceeding component temperature limits. In addition, proper thermal management will offer improved system durability and efficiency while providing a flexible, modular, and reduced weight structure. Traditional cooling systems are effective but they typically require high energy consumption which provides motivation for a paradigm shift. This presentation will examine the integration of passive heat rejection pathways in ground vehicle cooling systems using a “thermal bus.” Potential solutions include heat pipes and low-weight advanced materials with high thermal energy transfer rates to move heat from the source to ambient surroundings. An initial case study focuses on the integration of heat pipes into both a “cradle” (thermal connector between heat load and bus) and the thermal bus to transfer heat from the thermal load (e.g., internal combustion engine, electric motor, battery pack, power electronic, etc.) to the heat exchanger. A bench-top experimental component is being constructed to facilitate model validations.

2. Thermal Management Strategies Based on Active Monitoring and Control (project link)
Dr. Lin Ma, Professor of Aerospace & Ocean Engineering, Virginia Tech

        This talk describes our ongoing efforts to study battery thermal management in electric or hybrid powertrain systems, with a particular focus on the thermal behavior in a relatively large pack. An experimental platform was developed by combining dummy and real prismatic cells so that controlled tests can be performed in a battery pack consisting of 16 or more cells, and corresponding instrumentation developed to monitor fundamental thermal and fluid properties of the pack. Results have shown the effectiveness of this platform to study key aspects of cooling in a large pack, including both fundamental aspects such as model development/validation and applied aspects such as the design of active monitoring and control algorithms. A control strategy based on the model developed based on this platform was demonstrated to significantly reduce the parasitic power consumption of the cooling system.

        Dr. Ma started his faculty career after completing his PhD work in 2006 from the Department of Mechanical Engineering at Stanford University. His research focuses on the study of thermal-fluid systems, with a unique strength on the development and application of novel diagnostic techniques. He has authored over 70 archival journal papers in these research areas, and his work has been recognized by various awards, including the National Science Foundation’s CAREER award, SAE Ralph Teetor award, and Dean’s Award for Excellence in Research.

Thrust Area 2: Human Centered Modeling and Simulation

Projects presenting:
1. Teleoperation with Semi-Autonomous Behaviors and Latency (project link)
Mr. Justin Storms, Ph.D. Student, University of Michigan
Dr. Dawn Tilbury, Professor of Mechanical Engineering, University of Michigan

        Teleoperation of unmanned ground vehicles (UGVs) in distant environments is plagued with difficulties including communication delay and poor perception of the UGV’s environment. This project has explored the impact of delay on teleoperation performance, as well as methods for automating portions of the UGV operation. We have considered navigation for tasks involving path following and less structured exploration of environments. Operation modes ranging from pure teleoperation to semi-autonomous control have been tested with human subjects. One key finding has been that while semi-autonomy can improve teleoperation performance, the improvement is highly dependent on operation conditions. For example, semi-autonomy offers little improvement over teleoperation at low delay, however there are significant improvements at high delay.

        Justin Storms is a PhD candidate in the Department of Mechanical Engineering at the University of Michigan (UM). He has been working with TARDEC in the Automotive Research Center at UM since 2014. His research focuses on understanding the impact of communication latency and semi-autonomous control on the performance of teleoperated unmanned ground vehicles.

2. Quantifying the Benefits of Haptic Shared Control for Remotely Controlled and Semi- Automated Ground Vehicles (project link)
Dr. Amirhossein Ghasemi, Research Fellow, Mechanical Engineering, University of Michigan
Dr. Brent Gillespie, Associate Professor of Mechanical Engineering, University of Michigan

        Haptic shared control promises to improve performance in remote control of unmanned ground vehicles by combining the best attributes of human and automatic control. In this framework, the driver remains bodily in the loop, monitoring the automation’s behavior with a minimum of conscious attention. While a fluid definition of authority can ensure smooth transitions between automatic and human control, a risk arises when rules are not imposed to ensure that only one agent functions as leader at any given time. When rules involving role adoption are not imposed, the human and automation may attempt to impose differing control actions simultaneously that may cancel each other out. In this talk we present results from a series of experiments designed to investigate and resolve the question of role and authority negotiation in a haptic shared control task. In particular, we consider situations in which the negotiation over control authority is essential to avoid misinterpretation between the two collaborating partners. We manipulate leader/follower roles and investigate the effect on obstacle avoidance and lane following performance.
