본 발명은 차량용 이중대역 초음파 감지장치 및 그 제어방법이 개시된다. 본 발명의 차량용 이중대역 초음파 감지장치는, 제1 중심주파수 대역의 초음파를 송신하고 수신하는 제1 파형 송수신부; 제1 중심주파수 대역보다 높은 제2 중심주파수 대역의 초음파를 송신하고 수신하는 제2 파형 송수신부; 제1 파형 송수신부와 제2 파형 송수신부를 통해 순차적으로 초음파를 송수신하고, 중심주파수의 차에 따른 신호감쇄를 보상하여 송수신한 결과를 기반으로 각각 거리를 계산하며, 각각 계산된 거리를 통해 장애물 감지여부를 판단하여 최종 거리를 계산하는 제어부; 및 제어부에서 계산된 최종 거리를 출력하는 출력부;를 포함하는 것을 특징으로 한다.

    A dual-band ultrasonic sensing apparatus for vehicles and a control method thereof. The dual-band ultrasonic sensing apparatus includes a first waveform transceiver configured to transmit and receive ultrasound in a first center frequency band, a second waveform transceiver configured to transmit and receive ultrasound in a second center frequency band higher than the first center frequency band, a processor configured to sequentially transmit and receive ultrasonic waves through the first and second waveform transceivers, to calculate each distance based on the result of transmission and reception by compensating for signal attenuation due to a difference in center frequency, and to calculate a final distance by determining whether to detect an obstacle through each calculated distance, and an output unit configured to output the final distance calculated by the processor.
