Patent Images
1. An apparatus for detecting a vehicle, comprising:
- a magnetic sensor that continuously obtains a magnetic signal varied due to movement of a vehicle;
a gradient detecting unit that detects a gradient of the magnetic signal based on the obtained magnetic signal;
a vehicle status transitioning unit that generates status transition information of the vehicle based on the detected gradient; and
a vehicle coming-in/out determining unit that determines coming-in or coming-out of the vehicle based on the vehicle status transition information.
