Method for Generating Magnetic Field, Method for Detecting Lane by Using Magnetic Field, and Vehicle Using Same

A method for generating a magnetic field, a method for detecting a lane by using a magnetic field, and a vehicle using same are disclosed. According to the present invention, magnetic fields outputted from lanes coated with road-marking paint containing magnetic particles are detected with a magnetic sensor attached to a vehicle, and a plurality of lanes can be detected on the basis of the detected magnetic fields.
