Provided are a limp-home controlling method and a system for a hybrid vehicle, which can improve operability by minimizing vehicle vibration (JERK), wherein when high voltage is not applied to an inverter as a high voltage system of a hybrid vehicle is out of order, a counter electromotive force of a motor is used to operate an engine and when difference between an engine speed and a motor speed is the minimum, an engine clutch is connected.

    하이브리드 차량의 고전압 계통의 고장으로 인버터에 고전압이 인가되지 않는 상황에서 모터의 역기전력을 이용하여 엔진을 구동하고 엔진속도와 모터속도의 차이가 최소가 된 상태에서 엔진클러치를 접합시킴으로써, 차량 진동(JERK)을 최소화하여 운전성을 향상시킬 수 있는 하이브리드 차량의 림프홈 제어방법 및 시스템이 소개된다.
