According to the present invention, an apparatus for preventing shutdown comprises: an engine clutch; a hybrid control unit (HCU) controlling a vehicle by dualizing normal traveling control and limp-home traveling control and decelerating the speed of a vehicle and performing control transition in accordance with a state of the engine clutch; and an engine control unit (ECU) controlling an engine to enable a current engine revolution per minute(RPM) to reach the target engine RPM by comparing the current engine RPM with the target engine RPM in accordance with control transition. The present invention prevents RPM drop during limp-home traveling to prevent shut-down of a vehicle.

    본 발명에 따른 셧다운 방지 장치는, 엔진 클러치; 정상 주행 제어와 림폼(limphome) 주행 제어로 이원화하여 차량을 제어하며, 림폼 주행제어이면 상기 차량의 속도를 감속하고 상기 엔진 클러치의 상태에 따라 제어권 천이를 수행하는 HCU(Hybrid Control Unit); 및 상기 제어권 천이에 따라 현재 엔진 RPM(Revolution Per Minute)과 목표 엔진 RPM를 비교하여 상기 현재 엔진 RPM가 상기 목표 엔진 RPM에 도달하도록 엔진을 제어하는 ECU(Engine Control Unit);를 포함하는 것을 특징으로 한다.
