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.

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.

Traction electric motors and power electronic drives are called electric machine system, which has decisive impacts on energy consumption for HEV, PHEV and BEV etc. Different electric powertrains and the energy consumption of their corresponding vehicles are compared. The induction motors(IM) and interior permanent magnet (IPM) motors for the application of powertrains for BEVs are discussed. This presentation is focus on IPM motor design, manufacturing and validation & testing etc. The state of arts and their forward development trends of key components and materials for the PM motors and e-powertrains are summarized. High efficiency, more compact, low vibration and noise, safety and comfortability as well as the high ratio of performance to cost are compound requirements, which drive the integration of e-motor, power electronics and speed reducer/transmission. The algorithm and software on system performance are also discussed, and some conclusions and useful suggestions are given finally.

Electrification is one of the most effective ways to reduce energy consumption and emission of conventional vehicles. Powertrains for electric vehicles may consist of two electric driving inputs and automated transmissions with multiple speed ratios in order to obtain higher traction force and power propulsion efficiency. This presentation gives a brief comparison of performance of various EVs with powertrains equipped with transmissions of difference gear ratios; and a comparison between the energy efficiency of EVs with single driving input and that of EVs with dual driving inputs. Case studies on the gear shift control of EVs with a two speed AMT and a two speed AT using novel clutches and control methods; and driving mode control of EVs with dual driving inputs for better drivability and smoothness by employing different control algorithms are also provided and discussed.
