Disclosed is a method to prevent an engine stall using a virtual crank signal which uses a cam position sensor to prevent an engine stall before controlling an engine. According to the present invention, the method to prevent the engine stall using the virtual crank signal comprises: a first stabilization determination step of measuring an operating time of an engine to determine stability of the engine; a virtual crank signal storage step of using a crank position sensor to store a crank signal during one revolution of a crank shaft when the stability of the engine is determined to be maintained; a step of determining whether the crank position sensor fails; and an idle drive step of using the crank signal stored during the virtual crank signal storage step to control an RPM of the engine to allow idle drive of a vehicle when the crank position sensor fails.

    가상크랭크신호를 이용한 엔진 시동 꺼짐 방지 방법이 소개된다. 이를 위해 본 발명은, 엔진의 가동시간을 측정하여 엔진의 안정성을 판단하는 제1안정화여부판단단계; 엔진의 안정성이 유지된다고 판단시 크랭크포지션센서를 이용 크랭크 샤프트가 1회전하는 동안 크랭크 신호를 저장하는 가상크랭크신호저장단계; 상기 크랭크포지션센서의 고장 여부를 판단하는 단계; 및 상기 크랭크포지션센서의 고장시 차량의 아이들 구동이 이루어지도록 상기 가상크랭크신호저장단계에서 저장된 크랭크 신호를 이용 엔진의 회전수를 제어하는 아이들구동단계를 포함한다.
