摘要：This talk is focused on the current status and trend of technological developments of automotive transmissions of various types. The talk will first introduce concurrent designs of multiple ratio automatic transmissions, including the layouts of planetary gear trains, clutch arrangement and sequencing. Powertrain system dynamics and control strategies will also be presented in the talk, using an 8-speed production AT as the example. In addition to technologies of conventional automatic transmissions, the torque transmission and ratio control mechanisms for continuously variable transmissions (CVT) will also be highlighted in the talk. Furthermore, the system dynamics and operation control of hybrid and electric vehicles will be presented, using production hybrid vehicle models as case studies. The seminar ends with the dynamic modeling and control of dual clutch transmissions.
