A method for controlling deceleration of a vehicle includes: controlling a feed forward torque output unit to output feed forward torque stored in a map table, which corresponds to a current velocity of the vehicle and a deceleration target velocity of the vehicle when a deceleration event for the vehicle occurs; outputting feedback torque corresponding to the deceleration target velocity based on a vehicle velocity difference; controlling an adjustment factor output unit to adjust an application ratio of the feed forward torque stored in the map table, which corresponds to the vehicle velocity difference and a residual distance up to the deceleration event; and controlling a final control torque output unit to calculate final control torque for decelerating the vehicle based on the output feed forward torque and feedback torque and the adjusted application ratio and output the calculated final control torque to a powertrain of the vehicle.
