The present invention provides a system and a method for preventing a false alarm of an ultrasonic sensor. The system for preventing a false alarm of an ultrasonic sensor comprises: a ground height detection sensor to measure a distance between a bumper of a vehicle and the ground, and compare the measured distance with a reference distance to transmit a signal notifying a change of a height of the vehicle from the ground if the difference between the measured distance and the reference distance exceeds a prescribed level; and a sensor control unit to adjust a reference value which is a warning reference of an object detection sensor if the signal notifying the change of the height of the vehicle is received from the ground height detection sensor.

    본 발명은 초음파센서의 오경보 방지 시스템 및 그 방법을 제공한다. 상기 초음파센서의 오경보 방지 시스템은 차량의 범퍼와 지면 사이의 거리를 측정하고, 상기 측정된 거리를 기준거리와 비교하여 상기 측정된 거리와 상기 기준거리의 차가 일정수준을 초과하면 지면으로부터의 상기 차량의 높이가 변화되었음을 알리는 신호를 송신하는 지상고감지센서 및 상기 지상고감지센서로부터 상기 차량의 높이가 변화되었음을 알리는 신호를 수신하면 물체감지센서의 경보기준이 되는 레퍼런스(Reference) 값을 조정하는 센서제어부를 포함한다.
