Abstract
The vehicle detection apparatus includes a communication unit, a magnetic sensing unit, a calibration information generation unit, a vehicle detection unit, and a control unit. The communication unit receives information about movement of a reference vehicle from a central management center. The magnetic sensing unit senses the change in a magnetic field attributable to the movement of a vehicle, and generates a magnetic signal. The calibration information generation unit generates calibration information. The vehicle detection unit calibrates the change in the magnetic signal attributable to movement of an actual vehicle based on the calibration information, and detects the movement of the actual vehicle. The control unit controls the above units, and sets the mode to calibration information generation mode in order to generate the calibration information and to vehicle detection mode in order to sense the movement of the actual vehicle.
