A control unit for outputting a shifting signal for shifting down by one step from the current shifting stage when the operation is performed; The deceleration control apparatus for an automatic transmission vehicle, which includes a shift drive unit configured to change a shift stage by inputting a shift signal output from the control unit, does not upshift even if a driver presses the accelerator pedal while driving, for a predetermined time. When the brake pedal is operated while maintaining the current shift stage, the shift stage is shifted to obtain the effect of the engine brake, thereby preventing accidents by increasing the braking force, and providing a control method thereof.
