Abstract: A vehicle controller determines whether the position of a detected travel lane relative to an edge of a road being traveled by a vehicle may differ from an actual position; estimates a first required time for an action, which is required before the vehicle reaches a predetermined location, for the case that the position of the detected lane relative to the edge of the road is correct; estimates a second required time for the action for the case that the position of the detected lane differs from the actual position by a predetermined number of lanes; and sets start timing of the action, based on the second required time, so that the action will finish before the vehicle reaches the predetermined location, when the position of the detected lane may differ from the actual position and the second required time is longer than the first required time.

Abstract: A post-heating treatment device includes a detecting device for a height variation of a surface of the rail at every, predetermined pitch along a length direction of the rail, a control unit for defining a position of the rail to be a starting point of the welded section when the height variation detected by the detecting device at every predetermined pitch exceeds a predetermined threshold for the number of a predetermined times consecutively and defining a position of the rail to be an end point of the welded section when the height variation detected by the detecting device at every predetermined pitch is below the predetermined threshold for the number of the predetermined times consecutively, and a heating unit for heat treatment based on a position of the welded section detected by the detecting device. A post-heating treatment method using the post-heating treatment device is provided.

Abstract: A post-heating treatment device performs a post-heating treatment for a welded section of a rail, after an induction heating coil is automatically disposed at a predetermined position based on the welded section. The device includes welded section detecting unit for detecting the position of a welded section on a rail, a first coil and a second coil that form an induction heating coil, first coil moving unit for moving the first coil to a position spaced apart from the rail at a predetermined distance, second coil moving unit for moving the second coil to a position separated from the rail at a predetermined distance, where the second coil is contacted to the first coil, clamping unit for pressing against the contact portion between the first coil and the second coil, and current applying unit for applying a predetermined current to the formed induction heating coil.
