While the basic working principle and the mechanical construction of automatic transmissions in vehicles has not changed significantly, increased requirements for performance, fuel economy, and drivability, as well as the increasing number of gears has made it more challenging to design the systems that control modern automatic transmissions. New types of transmissions—continuously variable transmissions (CVT), dual clutch transmissions (DCT), and hybrid powertrains—have presented added challenges. A book from SAE International – “Dynamic Analysis and Control System Design of Automatic Transmissions” – relays how the fundamental principles of hydraulics and control systems are applied to today’s automatic transmissions. It opens with coverage of basic automatic transmission mechanics and then details dynamics and controls associated with modern automatic transmissions. Dynamic analysis helps to understand gear shifting mechanics and supports creation of the best design for gear shift control systems in passenger cars, trucks, buses, and commercial vehicles.
Topics covered include: gear shifting mechanics and controls, dynamic models of planetary automatic transmissions, design of hydraulic control systems, learning algorithms for achieving consistent shift quality, torque converter clutch controls, centrifugal pendulum vibration absorbers, friction launch controls, shift scheduling and integrated powertrain controls, continuously variable transmission ratio controls, dual-clutch transmission controls, and more.
Authors include Dr. Shushan Bai, Joel M. Maguire and Dr. Huei Peng.
Dr. Bai earned his B.S. degree in Mechanical Engineering from Huazhong University of Science and Technologies, China, and his M.S. and Ph.D. degrees in Electrical Engineering from Hokkaido University, Japan, both in the field of Automatic Controls. In his 23 years with GM Powertrain, he extensively worked on advanced development of automatic transmissions. Bai is also an adjunct faculty member in the Mechanical Engineering Department at the University of Michigan. He is the author of 30 technical publications and 35 patents.
Mr. Maguire received his undergraduate BSME degree from Michigan Technological University with an emphasis on design. He earned a graduate degree from Rennsselaer Polytechnic Institute in Troy New York. He began his automotive career in 1985 at General Motors Engineering Staff as an Associate Engineer, and currently is the Global Innovation Leader in GM Powertrain’s Advanced Hybrid Group.
Dr. Peng received his Ph.D. from the University of California, Berkeley. He is currently a Professor in the Department of Mechanical Engineering at the University of Michigan. His research interests include adaptive control and optimal control, with emphasis on their applications to vehicular and transportation systems. Dr. Peng’s current research focuses include design and control of hybrid vehicles and vehicle active safety systems. He has more than 200 technical publications, including 85 in referred journals and transactions, and three books.
