Shift schedule has an important influence on the performances of the auto with automated manual transmission (AMT). It will affect fuel economy, dynamic and emission performance of vehicle. According to the numbers of the control parameters, shift schedule can be roughly divided into threemain categories: single parameter, two parameters, and three parameters schedule.This paper introduces how to simulate and generate the shift schedule in the auto with AMT on the basis of two parameters shift schedule which is widely used in the real auto engineering by using the Gear Shift Program (GSP) module of the Cruise software.The result shows that this method could generate the shift schedule accurately and quickly.These works could be used in the effective calibration of transmissions and shorten thevehicle development cycle.
