The present invention relates to technique for decelerating a vehicle by equally generating vehicle deceleration with respect to an amount of stepping on a brake pedal during braking operation and, more specifically, provides a method for compensating regenerative braking torque, wherein when a brake pedal is stepped on, actual deceleration of the vehicle is compared with target deceleration using a predetermined deceleration map in accordance with the amount of stepping on the brake pedal to additionally generate regenerative braking torque of a motor up to compensation torque required for the actual deceleration to follow the target deceleration. 본 발명은 브레이크 조작시, 브레이크 페달 답입량에 대한 차량 감속도를 동일하게 발생시켜 차량을 감속하는 기술에 관한 것으로, 브레이크 페달 답입시 차량의 실제 감속도와 브레이크 페달의 답입량에 따라 미리 설정된 감속도맵을 이용한 목표 감속도를 비교하여 실제 감속도가 목표 감속도를 추종하기 위해 필요한 보상토크만큼 모터의 회생제동토크를 추가적으로 발생시키는 차량용 회생제동토크 보상하는 것이 소개된다.
