The present invention relates to a limp-home control method for a hybrid vehicle to improve running stability. The limp-home control method of the present invention includes: a failure determination step of determining, by a controller, a short circuit failure of a solenoid valve battery of a transmission; a first limp-home step of controlling, by the controller, solenoid valves involved in shifting to implement a limp-home shift stage while maintaining a state capable of supplying power to the solenoid valves when the short-circuit failure of the solenoid valve battery is determined; an engine necessity checking step of determining, by the controller, whether an engine clutch is required to be coupled; and a second limp-home step of driving, by the controller, a solenoid valve which controls the engine clutch to couple the engine clutch so as to implement limp-home driving by engine power when the engine clutch is required to be coupled.

    본 발명은 컨트롤러가 변속기의 솔레노이드밸브 배터리 단락 고장을 판단하는 고장판단단계와; 솔레노이드밸브 배터리 단락 고장이 판단되면, 상기 컨트롤러가 변속에 관여하는 솔레노이드밸브들에 전원을 공급할 수 있는 상태를 유지하면서, 상기 솔레노이드밸브들이 림프홈 변속단을 구현하도록 제어하는 1차림프홈단계와; 상기 컨트롤러가 엔진클러치의 체결이 필요한 상황인지 판단하는 엔진필요확인단계와; 엔진클러치의 체결이 필요한 상황이면, 상기 컨트롤러가 엔진클러치를 제어하는 솔레노이드밸브를 구동하여 엔진클러치를 체결함으로써, 엔진 동력에 의한 림프홈 주행을 구현하는 2차림프홈단계를 포함하여 구성된다.
