본 발명은 도로구배에 따라 제동에너지 회생단계를 가변하는 제어시스템 및 제어방법에 관한 것으로, 본 발명에 따른 제동에너지 회생단계 가변 제어시스템은 운전자가 패들 시프트로 수동 설정한 회생단계에 따라 정해진 감속도로 평지에서 타력주행 중 강판로나 등판로 진입으로 도로구배에 따른 감속도 차이가 발생하면, 상기 감속도 차이에 따른 보상토크를 반영하여 회생단계를 가변 제어하는 시스템으로서, 상기 시스템은 동작조건 판단부, 경사부하 기반 FF 제어부, 감속도 기반 FB 제어부, 및 코스팅 토크 반영부를 포함하는 것을 특징으로 한다. 또한, 본 발명에 따른 제동에너지 회생단계 가변 제어방법은 동작조건 판단 단계, 경사부하 기반 FF 제어값 출력 단계, 감속도 기반 FB 제어값 출력 단계, 및 코스팅 토크 반영 단계를 포함하는 것을 특징으로 한다.

    A system variably controls braking energy regeneration in a vehicle by reflecting a compensation torque depending on a difference in deceleration based on a road gradient when the vehicle travels over a downhill section or an uphill section of a road. The system includes a longitudinal sensor to receive the road gradient and compare the road gradient to a specific grade, and then compensate for the road gradient using a grade resistance value and a deceleration based value depending on a difference between deceleration manually set by a driver using a paddle shift and an actual vehicle deceleration. The system may include a controller to output a coasting torque as a correction torque that is a sum of the grade resistance value and the deceleration based value.
