Provided is an ultrasonic sensor module in a parking assisting device detecting and informing surrounding objects when traveling and parking a vehicle, which comprises: at least two ultrasonic sensors mounted on a vehicle, for transmitting an ultrasonic signal and receiving an ultrasonic signal reflected by an object; a driving unit for driving the ultrasonic sensor; and a control unit for controlling the overall operation of the ultrasonic sensor module and calculating a vertical distance between the object and the vehicle in a triangular measurement method by using the ultrasonic signals received from the two ultrasonic sensors. According to the present invention, by using the triangular measurement method in the parking assisting device, the distance to the object can be more accurately calculated, thereby improving the accuracy of the distance measurement method.

    본 발명의 차량의 주행 및 주차 시에 주변의 물체를 감지하여 알려주는 주차 보조 장치에서의 초음파 센서 모듈에서, 차량에 장착되어, 초음파 신호를 송신하고, 물체에 반사되어 돌아오는 초음파 신호를 수신하기 위한 둘 이상의 초음파 센서, 상기 초음파 센서를 구동하기 위한 구동부 및 초음파 센서 모듈의 전반적인 동작을 제어하며, 두 개의 초음파 센서에서 수신한 초음파 신호를 이용하여, 삼각 측정법으로 물체와 차량 간의 수직거리를 계산하는 제어부를 포함한다. 본 발명에 의하면, 주차 보조 장치에서 삼각 측정법을 이용하여 물체와의 거리를 보다 정확하게 계산하여, 거리 측정의 정확도를 향상시킬 수 있는 효과가 있다.
