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.
A limp-home control method for a hybrid vehicle may include: a fault determination step for determining, by a controller, whether a solenoid valve battery short circuit fault occurs in a transmission; a first limp-home step for controlling, by the controller, solenoid valves to implement a limp-home gear stage while maintaining a state where power is suppliable to the solenoid valves involved in shifting gears when it is determined that the solenoid valve battery short circuit fault exists; an engine necessity verification step for verifying, by the controller, whether engagement of an engine clutch is needed; and a second limp-home step for driving, by the controller, a solenoid valve controlling the engine clutch to engage the engine clutch, implementing limp-home driving by engine power when the engagement of the engine clutch is needed.
