The present invention relates to an ultrasonic sensor system which includes: an ultrasonic sensor which emits a first ultrasonic wave when an input voltage is applied and generates an output voltage when a second ultrasonic wave returning after being reflected by an external object is received; a determination unit for determining a defect if a duration for the voltage of the ultrasonic sensor right after the first ultrasonic wave is emitted is greater than the sum of a previously known normal duration and a critical duration; and a notification providing unit for providing a notification if the defect is determined. Accordingly, it is possible to normally operate the ultrasonic sensor system even if the defect is generated due to deterioration.

    본 발명은 입력전압이 인가되면 제1초음파를 방사하고, 외부물체에 반사되어 되돌아오는 제2초음파를 수신하면 출력전압을 생성하는 초음파센서;와 제1초음파가 방사된 직후, 초음파센서의 전압에 대한 일 시간이 미리 알고 있는 정상시간과 임계시간의 합보다 크면 고장임을 판단하는 판단부; 및 고장임이 판단되면, 알림을 제공하는 알림제공부를 포함하는 초음파센서 시스템에 관한 것이다.
