Disclosed are a failure detection apparatus for a vehicle and a control method thereof. According to one embodiment of the present invention, the failure detection apparatus for a vehicle includes: a battery installed in a vehicle; a plurality of electronic control units (ECU) each electrically connected to the battery; and a master ECU connected to the plurality of ECUs over a network and configured to perform a controller area network (CAN) communication with the plurality of ECUs. The master ECU is configured to send a request, to the plurality of ECUs, for battery voltage information that a voltage of the battery is monitored after a vehicle is started, to receive the battery voltage information, and to determine whether there is a failure in the battery or in a wire harness electrically connecting the battery to the plurality of ECUs, by using a result from the comparison between each of the received battery voltages and a reference voltage. Accordingly, the present invention aims to provide a failure detection apparatus for a vehicle and a control method thereof capable of effectively detecting a failure of a battery or a wire harness.
차량용 이상검출장치 및 그 제어방법이 개시된다. 본 발명의 일실시예에 따른 차량용 이상검출장치는 차량에 마련된 배터리와, 배터리와 전기적으로 각각 연결된 복수의 ECU 및 복수의 ECU와 네트워크로 연결되어 복수의 ECU와 캔 통신하는 마스터 ECU를 포함하고, 마스터 ECU는 차량 시동 후 복수의 ECU에 배터리의 전압을 모니터링한 배터리전압정보를 요청하여 수신하고, 수신된 각 배터리전압을 기준전압과 비교한 결과를 이용하여 배터리의 이상 또는 배터리와 복수의 ECU를 전기적으로 연결하는 와이어 하네스의 이상을 판단한다.
