Abstract
A travel control device acquires subject vehicle information including the position of a subject vehicle, acquires lane marker information including positions of lane markers, sets control areas with reference to the lane markers, and controls a travel position of the subject vehicle so that the subject vehicle travels between a pair of control areas set at right and left of the subject vehicle. The lane markers include a change-point lane marker and includes a course change point. When the pair of control areas set with reference to the change-point lane marker comprises one of the pair at a course change side of the subject vehicle and the other of the pair, the ratio of a width of the other to a width of the one is set larger than the ratio of the widths of control areas set with reference to a lane marker other than the change-point lane marker.
