| Abstract: | The shift schedule is the basic of the automatic transmission system. From the point of view of enhancing the output power of a vehicle, a new shift schedule was developed in which the parameters of throttle position, pump speed and turbine speed were taken as variables. The points of intersection of turbine power-output in different shifts were taken as the shift points. In order to verify the shift schedule,the dynamic model of the vehicle powertrain was established and the simulation system of automatic transmission was developed by using a software package of Matlab/Simulink. The simulation results proved that the shift schedule was correct and the power-output of the turbine, through shifting-up or shifting-down, could be heightened immediately. |
