1. A driving support device comprising:
- image acquisition means for acquiring an image of an area around a vehicle on which the image acquisition means is disposed;
driving assistance means for assisting a driver in driving the vehicle based on the image that is acquired by the image acquisition means;
mark information storage means for storing location information for a road surface marking that is formed on a road surface;
road surface marking detection means for detecting the road surface marking that is formed on the road surface on which the vehicle is traveling, based on the image that is acquired by the image acquisition means; and
object distance computation means for computing an on-road distance from the vehicle to a control object that is associated with the detected road surface marking, based on the road surface marking detected by the road surface marking detection means and on the location information that is stored in the mark information storage means, whereinthe driving assistance means assists the driving of the vehicle based on the computed on-road distance from the vehicle to the control object.

Abstract
In a case where it is determined that a road surface marking exists within a specified range from a vehicle 2 (YES at S2), the road surface marking is recognized based on an image that has been acquired by a rear camera 3 (S3), an on-road distance from the vehicle 2 to a control object that is associated with the recognized road surface marking is computed (S5 to S7), and in a case where it has been determined that the on-road distance to the control object has become a specified distance (YES at S8), driving guidance and the vehicle control are performed in accordance with the type of the associated control object (S11).
