Professor of Mechanical and Aerospace and Electrical and Computer Engineering and Director, Center for Automotive Research, The Ohio State University.
Mobility is undergoing dramatic transformations that will radically change the way we move and access work and leisure time. This presentation presents a broad overview of the technologies and challenges ahead of us in the medium and long term, touching on various topics related to smart cities and smart mobility. The city of Columbus, winner of the US DOT Smart City program, is implementing a number of programs related to mobility, data exchange and EV adoption, which will be reviewed in the presentation. Looking more closely at vehicle technology, the seminar also includes an overview of the ARPA-E NEXTCAR program, describing how vehicle connectivity and automated driving capabilities can considerably enhance the fuel economy of a light-duty passenger car. Finally, the talk closes with some considerations on the challenges that we face in the adoption and implementation of these new technologies.
Biography: Giorgio Rizzoni, the Ford Motor Company Chair in ElectroMechanical Systems, is a Professor of Mechanical and Aerospace Engineering and of Electrical and Computer Engineering at The Ohio State University (OSU). He received his B.S. (ECE) in 1980, his M.S. (ECE) in 1982, his Ph.D. (ECE) in 1986, all from the University of Michigan. Since 1999 he has been the director of the Ohio State University Center for Automotive Research (CAR), an interdisciplinary university research center in the OSU College of Engineering. His research activities are related to modeling, control and diagnosis of advanced vehicles, energy efficiency, alternative fuels, the interaction between vehicles and the electric power grid, vehicle safety and intelligence, and policy and economic analysis of alternative fuels and vehicle fuel economy. He is currently serving as PI on a 2017-2020 ARPA-E NEXTCAR program that aims to tied vehicle automation and connectivity to powertrain control and fuel economy. He has contributed to the development of graduate curricula in these areas, and has served as the director of three U.S. Department of Energy Graduate Automotive Technology Education Centers of Excellence: Hybrid Drivetrains and Control Systems (1998-2004), Advanced Propulsion Systems (2005-2011, and Energy Efficient Vehicles for Sustainable Mobility (2011-2016). Between 2011 and 2016 he served as the OSU Site Director for the U.S. Department of Energy China-USA Clean Energy Research Center - Clean Vehicles. Prof. Rizzoni is a Fellow of SAE (2005), a Fellow of IEEE (2004), a recipient of the 1991 National Science Foundation Presidential Young Investigator Award, and of numerous other technical and teaching awards.

E-Motors can easily operate at high speeds of 30.000 rpm or even more. An E-Motor with a peak torque of 100 Nm between stand still and 10.000 rpm and a constant power of 100 kW between 10.000 rpm and 30.000 rpm needs only small space. But such a Motor needs speed reduction with a total ratio of about 20. That could be done in two gear stages but with a high input speed in the first stage. To limit the noise excitations it is necessary to reduce the variations of the stiffnesses in the gearset as much as possible. For that purpose we found a layout of a planetary gearset with nearly constant stiffness that should be used in the first stage with the rotor of the e-motor connected to the sun gear.
Biography: Prof. Dr.-Ing. Peter Johannes Tenberge since 2012 is Chair of industrial and automotive drivetrains at Ruhr-University Bochum. He has previously served (1994- 2012) as professor for machine elements at Chemnitz University; (1992-1994) general manager for development and sales of INA Motorenelemente Schaeffler KG; (1989-1992) head of R&D of INA Wälzlager Schaeffler KG; and (1986-1989) as a project engineer at Zahnradfabrik Friedrichshafen AG. Tenberge has, in his career thus far, proposed for automotive applications several transmission concepts for AT, DCT, CVT and Hybrids, and in 2012 was awarded the SAE/Timken Howard Simpson Automotive Transmission and Driveline Innovation Award. He also keeps busy working on various industrial applications in which he works on design, development and simulation tools for a more precise and quicker layout of transfer gears, worms gear, bevel gears and planetary gears. Tenberge is also the holder or co-holder of more than 200 national and international patent applications.
