The present invention relates to a driving assistance system, including: a detector configured to detect a forward vehicle, positioned in front of a drivers own vehicle, or a driving lane on which the drivers own vehicle or the forward vehicle runs based on image data outputted by a camera for sensing the front; a first calculator configured to calculate a first forward vehicle width with respect to the forward vehicle detected by the camera, and a second forward vehicle width with respect to the forward vehicle based on a first driving lane width about the driving lane and a second driving lane width about a predetermined driving lane; and a second calculator configured to calculate a distance to the forward vehicle based on the focal plane distance of the camera, the first forward vehicle width and the second forward vehicle width. Accordingly, the present invention aims to provide a driving assistance technology for precisely detecting a distance to a forward vehicle regardless of actual driving environment.
