This control method is for a travel control device 100 which is provided with a first detector 110 for detecting obstacles around the local vehicle traveling in a first lane and a second detector 110 for detecting a second lane adjacent to the first lane, and which, in a lane change target position in the second lane, configures a first range of a size no less than that occupied by the local vehicle on the road surface, detects, as a second area, an area in the second lane which is located to the side of the local vehicle and in which no obstacles are present, and permits the local vehicle to change lanes if the second area includes the first area; this control method involves a first step for determining the travel scene of the local vehicle on the basis of the travel state of the local vehicle, a second step for acquiring the degree of necessity of a lane change determined in advance in the travel scene, and a third step in which, if the degree of necessity is greater than or equal to a first determination value, correction is performed to reduce the first area or enlarge the second area to a greater degree than would be the case if the degree of necessity were less than the first determination value. |
