报告内容简介：
This talk focuses on the current status and trend of technological developments of various types of automotive power transmission systems. 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 then be presented afterwards, using an 8-speed production AT as the case study. In addition to technologies of conventional automatic transmissions, the torque transmission and ratio control mechanisms for continuously variable transmissions (CVT) will be another highlight 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 clutch torque formulation and control of dual clutch transmissions. The contents of the seminar will be based on summarizing the research results of the speaker and other researchers in the public domain.
