본 실시예에 의하면, 차량에 장착된 복수의 초음파 센서 내의 각각의 초음파 센서를 순차적으로 작동시켜 각각의 출력 신호를 생성하는 신호 송신부; 상기 각각의 출력 신호를 생성하는 상기 각각의 초음파 센서에 대한 인접 초음파 센서의 수신값을 획득하는 신호 감지부; 상기 수신값의 이상 여부를 판정하는 이상 판정부; 및 상기 이상 여부를 판정한 결과에 따라 상기 각각의 초음파 센서에 대한 조치를 실행하는 판정결과 처리부를 포함하는 센서 무결성 결정장치를 제공한다. An apparatus for determining integrity of a sensor includes a signal transmission unit configured to sequentially operate each of a plurality of ultrasonic sensors mounted on a vehicle to generate respective output signals. The apparatus also includes a signal sensing unit configured to acquire a received value of an adjacent ultrasonic sensor adjacent to each of the plurality of ultrasonic sensors which generate the respective output signals. The apparatus further includes an anomaly determining unit configured to determine whether the received value is abnormal. The apparatus additionally includes a determination-result processing unit configured to perform a response for each of the ultrasonic sensors according to a result of determining anomaly.
