Disclosed are a device and a method to sense a vehicle by using a terrestrial magnetism sensor. The vehicle sensing device of the present invention recognizes a vehicle by sensing a change in terrestrial magnetism by the vehicle, passing through a passage. At this point, the vehicle sensing device is capable of accurately calculating the number of passing vehicles by using an additional distance sensor even when a change of the terrestrial magnetism is not distinguished for each vehicles since the vehicles consecutively pass.
지자기 센서를 이용한 차량 감지장치 및 그 감지방법이 개시된다. 본 발명의 차량감지장치는 차량통행로를 통과하는 차량에 의한 지구자기장의 변화를 감지하여 차량을 인식한다. 이때, 차량감지장치는 별도로 거리센서를 사용하여 차량이 연이어 통과함에 따라 지구자기장의 변화가 차량별로 구분되지 않는 상황에서도 통과한 차량의 개수를 정확하게 계산할 수 있다.
