Abstract:
(EN) An ultrasonic sensor module for detecting and reporting a nearby object during the travel or parking of a vehicle according to the present invention comprises: two or more ultrasonic sensors which are mounted on the vehicle and are for transmitting ultrasonic signals and receiving ultrasonic signals that are reflected back from the object; a driving unit for driving the ultrasonic sensors; a control unit which controls the overall operation of the ultrasonic sensor module and uses the ultrasonic signals received by the two ultrasonic sensors to calculate the vertical distance between the object and the vehicle by means of a triangulation method. According to the present invention, there is an effect in that the distance to the object can be more accurately calculated using the triangulation method to improve the accuracy of a distance measurement.
(FR) Un module de capteurs ultrasonores pour détecter et signaler un objet proche pendant le déplacement ou le stationnement d'un véhicule selon la présente invention comprend: au moins deux capteurs ultrasonores qui sont montés sur le véhicule et qui sont destinés à transmettre des signaux ultrasonores et à recevoir des signaux ultrasonores qui sont réfléchis par l'objet; une unité d'entraînement pour entraîner les capteurs ultrasonores; une unité de commande qui commande le fonctionnement global du module de capteurs ultrasonores et utilise les signaux ultrasonores reçus par les deux capteurs ultrasonores pour calculer la distance verticale entre l'objet et le véhicule au moyen d'un procédé de triangulation. Selon la présente invention, l'effet obtenu est que la distance à l'objet peut être calculée plus précisément à l'aide du procédé de triangulation pour améliorer la précision d'une mesure de distance.
(KO) 본 발명의 차량의 주행 및 주차 시에 주변의 물체를 감지하여 알려주는 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, 삼각 측정법을 이용하여 물체와의 거리를 보다 정확하게 계산하여, 거리 측정의 정확도를 향상시킬 수 있는 효과가 있다.
