Abstract
Disclosed herein are a method and a system for recognizing a space of a road shoulder using an ultrasonic wave sensor, a radar and an imaging device. The method includes: controlling the radar to transmit a radar beam within a preset range based on the vehicle location; detecting a fixed object located within the preset range using a reflective wave of the radar beam received by the radar; calculating a distance between the fixed object and the vehicle using the radar when the fixed object is located within the preset range; detecting a solid line lane marking in a front image of a travel lane obtained from the imaging device; and recognizing the calculated distance between the fixed object and the vehicle as a space width of the road shoulder when the solid line lane is in the front image of the travel lane.
