본 발명은 전동화 차량의 구동력 제어 장치 및 방법에 관한 것으로, 차량의 구동륜에 장착되어 구동륜 속도를 측정하는 휠속 센서, 상기 차량의 발진 상황에서 요구토크에 따른 실제 차량 거동과 차량 거동 모델을 기반으로 상기 구동륜 속도에 따른 추정된 차량 거동을 비교하여 1차 외란을 추출하는 외란관측기, 상기 1차 외란으로부터 기설정된 주파수 범위의 2차 외란을 추출하는 필터, 상기 2차 외란을 상쇄하기 위한 보상토크를 연산하는 보상기, 상기 보상토크에 기반하여 상기 요구토크의 보상 여부를 결정하는 히스테리시스 회로 및 상기 요구토크 및 상기 보상토크를 이용하여 보상요구토크를 연산하는 연산기를 포함한다.

    A system and a method are configured to control a traction force of a vehicle, for example, an electrified vehicle. The system includes wheel speed sensors mounted on drive wheels, respectively, of the vehicle to measure a drive wheel speed, a disturbance observer for extracting a primary disturbance by comparing an actual vehicle behavior based on a required torque with a vehicle behavior estimated based on the drive wheel speed using a vehicle behavior model in an acceleration situation of the vehicle, a filter for extracting a secondary disturbance in a preset frequency range from the primary disturbance, a compensator for calculating a compensation torque for cancelling the secondary disturbance, a hysteresis circuit for determining whether to compensate for the required torque based on the compensation torque, and a calculator for calculating a compensated required torque using the required torque and the compensation torque.
