An autonomous driving control apparatus may include an image capturing unit configured to capture a driving road image of an ego vehicle; and a control unit configured to generate virtual lanes on a road with no lines, the virtual lanes corresponding to the number of lanes which are decided based on the width of the road with no lines, when the road with no lines is detected in front of the ego vehicle through the driving road image captured by the image capturing unit, and control autonomous driving of the ego vehicle to drive on one of the generated virtual lanes. When a front object is detected from the driving road image, the control unit may control the autonomous driving of the ego vehicle to avoid the front object and drive on the road with no lines.
