본 발명은 차량의 고장 진단 장치 및 그 방법에 관한 것으로, 차량의 전장부하가 작동하지 않는 상태(OFF 상태)에서 상기 전장부하의 전압에 기초하여 상기 전장부하와 상기 전장부하에 연결된 전원 공급라인(Circuit)에서 발생하는 고장 여부를 진단함으로써, 차량의 전장부하를 작동시키지 않고도 상기 전장부하와 상기 전장부하에 연결된 전원 공급라인에서 발생하는 단락(Short circuit) 또는 단선(Open circuit)을 정확도 높게 진단해 낼 수 있는 차량의 고장 진단 장치 및 그 방법을 제공하고자 한다. 이를 위하여, 본 발명은 차량의 고장 진단 장치에 있어서, 차량 내 전장부하를 구동시키는 구동부; 및 상기 전장부하가 작동하지 않는 상태에서, 상기 전장부하와 상기 구동부 사이의 전압을 측정하고, 상기 측정된 전압에 기초하여 단락(Short circuit) 또는 단선(Open circuit)을 진단하는 제어부를 포함한다.
The present invention relates to an apparatus for diagnosing a failure of a vehicle and a method thereof, which diagnoses whether the failure occurs at an electric field load of a vehicle and a power supply circuit connected to the electric field load based on voltage of the electric field load in a state that the electric field load of the vehicle is not operated (OFF state), thereby being able to diagnose a short circuit or an open circuit generated at the electric field load and the power supply circuit connected to the electric field load even though the electric field load of the vehicle is not operated. To this end, the present invention provides an apparatus for diagnosing the failure of a vehicle, comprising: a driving unit driving the electric field load within the vehicle; and a control unit, in a state of the electric field load is not operated, measuring voltage between the electric field load and the driving unit and diagnosing the short circuit or the open circuit based on the measured voltage.
