본 발명은 하이브리드 차량의 엔진 시동 제어 장치 및 방법에 관한 것으로, 엔진과 벨트로 연결되는 HSG, HSG 속도를 측정하는 센서, 및 상기 엔진 시동 시 상기 HSG에 시동 토크 인가 후 인가된 시동 토크에 기반하여 추정된 HSG 속도와 상기 HSG 속도를 이용하여 상기 벨트의 슬립량을 연산하고, 연산된 슬립량에 기반하여 토크 변화율 보정치를 연산하고, 상기 토크 변화율 보정치를 기반으로 상기 시동 토크의 변화율을 보정 제어하는 프로세서를 포함한다.
An engine start controller for a hybrid vehicle and a method thereof are provided. The engine start controller includes a hybrid starter generator (HSG) that is connected to an engine by a belt, a sensor that is configured to measure an HSG speed, and a processor that applies a starting torque to the HSG. When starting the engine, the processor calculates an HSG speed estimated based on the applied starting torque and calculates an amount of slip of the belt using the HSG speed. In addition, the processor calculates a torque change rate correction value based on the calculated amount of slip, and corrects a rate of change rate in the starting torque based on the torque change rate correction value.
