The present invention relates to a lamp driving system having a fail-safe function, and a method thereof. The lamp driving system of the present invention comprises: a fault diagnosis unit mounted on an ICU for performing control of supplying or blocking a battery power supplied from a battery of a vehicle to a lamp, and diagnosing an abnormal operation or fault of an MCU by monitoring a PWM signal of the MCU provided in the ICU; and a lamp driving unit having an IPS and the lamp connected to an output terminal, and forcibly driving the lamp by outputting a turn-on signal of a high level to the IPS connected to the output terminal when a multi-function (M/F) switch having a request for lamp driving is turned on while the abnormal operation or fault of the MCU is diagnosed by the fault diagnosis unit. Accordingly, a fail-safe function of preventing a problem of driving a vehicle by forcibly driving the lamp to be operated by a driver can be implemented even if a situation where the ICU or the MCU of IGPM for lamp driving is abnormally operated occurs.

    본 발명은 fail-safety 기능을 구비하는 램프 구동 시스템 및 그 방법에 관한 것이다. 또한, 본 발명은 차량의 배터리로부터 공급되는 배터리 전원을 램프에 공급하거나 차단하는 제어를 수행하는 ICU에 탑재되고, ICU에 구비된 MCU의 PWM 신호를 모니터링하여 그 MCU의 비정상 동작 또는 고장 여부를 진단하는 고장 진단부 및 IPS와 램프가 출력단에 연결되고, 고장 진단부로부터 MCU의 비정상 동작 또는 고장이 진단된 상태에서 램프 구동을 요청하는 멀티 펑션 스위치(M/F Switch)가 턴온되면, 출력단에 연결된 IPS에 하이 레벨의 턴온 신호를 출력하여 램프를 강제적으로 구동시키는 램프 구동부를 구비하므로, 램프 구동을 위한 ICU 또는 IGPM의 MCU가 정상적으로 동작하지 못하는 상황이 발생하더라도, 운전자가 조작하고자 하는 램프를 강제 구동시켜서 차량 주행에 문제가 없도록 하는 fail-safety 기능을 구현할 수 있다.
