摘  要:
Based on the automatic shift method with the excellent characteristics of dual-parameter( vehicle speed and throttle position) combined automatic transmission shift,its shift regulation is designed. The kinetic equations of the relevant parts( engine,automatic transmission and vehicle driving Kinetics),which affect the dynamic shift regulation of automatic transmission are analyzed. The kinetic simulation model of each component is established by the SIMULINK software and the simulation control model of dual-parameter dynamic shift is established by the STATEFLOW software. Lastly,the designed automatic shift regulation is analyzed in detail by using the working condition of rapid speeding-up,and good automobile dynamic property is obtained.
