A method for determining whether a vehicle detector is disclosed. The method includes the steps of: outputting a sensor signal proportional to the sensing result of a magnetic field sensor; determining whether a change in frequency of the sensor signal exceeds a first standard; and when the change exceeds the first standard, determining whether the vehicle is parked in a parking space corresponding to the vehicle detector based on the determination result of an adjacent comparison vehicle detector. Therefore, it is possible to accurately determine whether the vehicle is parked in the parking space.

    본 발명의 일 실시 예는, 자기장센서의 센싱 결과에 비례하는 센서신호를 출력하는 단계, 상기 센서신호의 주파수의 변화량이 제1기준을 초과하는지 여부를 판단하는 단계 및 상기 변화량이 상기 제1기준을 초과하면, 인접한 비교차량탐지기의 판단결과를 기초로 상기 차량탐지기에 대응되는 주차공간에 차량이 주차되었는지 여부를 판단하는 단계를 포함하는, 차량탐지기의 주차여부 판단 방법을 개시한다.
