SELF-POSITION CORRECTION METHOD AND SELF-POSITION CORRECTION DEVICE FOR DRIVE-ASSISTED VEHICLE

In lane selection control in which a lane in which a host vehicle travels is selected based on the map information and information acquired by an external sensor that acquires periphery information of the host vehicle, a self-position correction object in an intended travel route is identified based on the map information. When the host vehicle reaches a correction point where the self-position correction object is present, a determination is made as to whether or not the self-position correction object can be recognized by the external sensor from the lane in which the host vehicle travels. Upon determined that the self-position correction object cannot be recognized from the center lane in which the host vehicle travels, a lane change to a leftmost lane where the self-position correction object can be recognized is made before the host vehicle reaches the correction point.
