Claim:
1. A shift control apparatus of an automatic transmission, comprising: a data detector configured to detect driving data to perform a shift control; and a vehicle controller configured to determine a shift gear stage based on the driving data and control a transmission based on the shift gear stage, wherein the vehicle controller sets driver's demand acceleration based on the driving data, sets a gear stage range which arrives at the driver's demand acceleration, and sets a target gear stage, at which fuel consumption is minimized, in the gear stage range to instruct a shift, wherein the vehicle controller sets a basic demand acceleration map representing a demand acceleration for a vehicle speed and a position of an accelerator pedal and applies weight values for a change rate of the position of the accelerator pedal and a road gradient condition, respectively, of the driving data to the basic demand acceleration map to define a driver's demand acceleration map, and wherein the vehicle controller extracts the demand acceleration matching the vehicle speed and the position of the accelerator pedal of the driving data from the driver's demand acceleration map to set the driver's demand acceleration.
