<p><P>PROBLEM TO BE SOLVED: To provide an on-board apparatus and a method executed by the apparatus, capable of changing the start timing of an operation according to the lane that a vehicle is traveling in. <P>SOLUTION: Based on edge images obtained by performing an edge detection process on images taken in the direction of travel of one's own vehicle, a lane marker recognizing portion 102 recognizes an edge of a lane marker captured in the images. When recognizing the edge of the lane marker, the lane marker recognizing portion 102 counts the number of lane markers on the right and left of the lane of the own vehicle according to the edges recognized. A passing lane determining portion 103 determines whether or not the lane in which the vehicle is traveling is a passing lane according to the number of lane markers counted by the lane marker recognizing portion 102. A change instruction unit 104 creates determination information if the lane is determined by the passing lane determining unit 103 as a passing lane, and a device included in a support device 2 having acquired the determination information varies the start timing of the operation to make it earlier. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
