Study on Shift Schedule and Auto-Controlling Simulation of Automatic Transmission

New shift schedule and auto controlling strategy for automatic transmission were proposed from the point of view of saving energy. In order to verify this shift schedule, a simulation program using a software package of Matlab/Simulink was developed. The simulation results show that the shift schedule is correct, and the efficiency of the torque converter, through shift schedule expressions, can be completely limited in an idealized range at any working condition. This shift schedule has enriched the theory of vehicle automatic maneuvering and will improve the efficiency of hydrodynamic drive system of vehicle.
