"Energy Efficient Powertrain Controls from Laboratory to Production"

Xubin Song, Eaton Corp.

Since the world is becoming more serious concern about global warming, it is our responsibility as a citizen on the earth to save energy and preserve the living environment while modernizing the world and our life. Energy efficient technology becomes a critical and essential part of green transportation systems. This presentation focuses on application of control technologies to address vehicular energy consumption to deliver the best vehicle performance of such as fuel economy and comfort from laboratory to production. This challenging perspective will be illustrated through my own experience from the ground vehicle industry.

Controls become necessity for modern vehicles. Exploring control solutions for vehicle mass production truly poses a great challenge for engineers. Control engineering involves mechanical, electrical, and software engineering for key-turn production solution. My decade long experience in the vehicle industry focuses on developing the energy efficient control technologies to meet the criteria of system robustness and performance consistency for the ground vehicle applications. This presentation shows some design examples of developing superior powertrain systems from engine, transmission to brake/wheel assembly, for example, applying semi-active clutch control to mitigate driveline torsional vibrations for commercial vehicles, using energy harvesting motor control to smooth the engine shutdown for HEV, and monitoring the power line resistance to assess the on-board vehicular power quality. In the end, I will briefly talk about concurrent intelligent powertrain controls we are working on to further promote the fuel economy performance for commercial vehicles.

Xubin Song received his PhD from Virginia Tech in 1999 and MSME from North Carolina A&T State University in 1996 in USA, with B.S. from Nanjing University of Aeronautics & Astronautics in 1986 and M.S. from China Academy of Launch Vehicle in 1988 in China. With the background of aerospace industry in China and vehicle industry in USA, his research interest focuses on nonlinear and non-smooth dynamics and control and energy efficient powertrain systems for ground vehicles, holding 6 USA and 1 European patents and publishing more than 50 papers.

He worked as engineer for the China Academy of Launch Vehicle from 1988 to 1994 in Beijing. His industry experience in USA includes development of iBOT human transporter (1999-2000) for Johnson & Johnson, and chassis system controls with Visteon Corp (2000-2004). Since 2004, Dr. Song, as a principal engineer at Eaton Corp, has focused on advanced powertrain controls for commercial vehicles.

He is an active member of IEEE, ASME and SAE, holding membership of several technical committees. Currently he is working as a founding editor-in-chief of International Journal of Powertrains under the Indersceince publisher, and also serves as an associate editor of the ASME Journal of Dynamic Systems, Measurement and Control.
