Abstract: From the point of view of saving energy, a new shift schedule
and auto-controlling strategy for automatic transmission are
proposed. In order to verify this shift schedule, a simulation
program using a software package of Matlab/Simulink is developed.
The simulation results show the shift schedule is correct. This
shift schedule has enriched the theory of vehicle automatic
maneuvering and will improve the efficiency of hydrodynanic
drive system of the vehicle.
