Abstract The theory about dynamical model of the clutch engagement and the shift quality was discussed. During the start-up process, the three-parameter fuzzy control strategy was proposed because the jerk or the slide friction work increased during the clutch engagement. The simulated experiment was carried out with Simulink for the vehicle starting process. Three parameters, including the accelerator aperture, the accelerator aperture changing rate and the road resistance, were the fuzzy controller＇ s input, which indicated the road condition of the external environment during the start-up process and the driver＇ s intention. The clutch joint speed was controlled by the three parameters. The simulated results indicate that the road resistance added as a controller parameter can improve the quality of the clutch engagement during the start-up process.
