Zusammenfassung:	The present invention relates to an emergency driving system and method for a hybrid vehicle with a damaged engine bearing, which is able to, when damage to a bearing installed in an engine is detected, drive the hybrid vehicle while preventing the damaged bearing from getting worse by a driving motor (20) and an HSG (30). According to the present invention, the emergency driving method for a hybrid vehicle with a damaged engine bearing comprises: (S110) a bearing damage detection step to detect damage to an engine (10) bearing and determine the information; (S120) an engine driving maintaining step to maintain the driving of the engine (10) in a preset limp home mode; (S140) a first SOC comparison step to compare to see if the state of charge (SOC) of a high-voltage battery (51) is higher than or equal to a preset first reference value (TH1) to drive the hybrid vehicle (1) with the engine (10); and (S150) a first emergency driving step to, if the SOC is higher than or equal to the first reference value (TH1), drive the hybrid vehicle (1) just by the driving force of the engine (10). 본 발명은 엔진에 설치된 베어링의 손상을 감지한 경우 구동모터와 HSG에 의해 상기 베어링의 손상이 더 심해지는 것을 방지하면서 하이브리드자동차를 구동시킬 수 있도록 한 엔진의 베어링이 손상된 하이브리드자동차의 비상구동시스템 및 방법에 관한 것이다. 본 발명에 따른 엔진의 베어링이 손상된 하이브리드자동차의 비상구동방법은, 엔진(10)에 설치된 베어링의 손상을 감지하고, 이를 확정하는 베어링손상감지단계(S110); 상기 엔진(10)을 미리 설정된 림프홈모드로 구동을 유지시키는 엔진구동유지단계(S120); 고전압배터리(51)의 SOC(State Of Charge)가 상기 하이브리드자동차(1)를 상기 엔진(10)으로 주행시키는 것으로 미리 설정된 제1기준값(TH1)보다 높거나 같은 지를 비교하는 제1SOC비교단계(S140); 및 상기 SOC가 상기 제1기준값(TH1) 보다 높거나 같으면, 상기 구동모터(20)와 상기 HSG(30)는 정지시키고, 상기 엔진(10)의 구동력만으로 상기 하이브리드자동차(1)를 구동시키는 제1비상구동단계(S150);를 포함하는 것을 특징으로 한다.
