Research on Analyse for Shifting Process of Automatic Transmission

Abstract

The author establish the dynamic model of vehicle power transmission, taking three gear to four gear as an example, Simulate the vehicle acceleration, Research the change of clutch control oil pressure and torque transmission. In order to improve the power performance and comfort performance of the whole vehicle in the shifting process, the control parameters of the shifting process are optimized to minimize the acceleration fluctuation of the whole vehicle in the shifting process
