The present invention provides a travel assistance method and a travel assistance device (19) for a vehicle in which, when performing a first lane change with autonomous lane change control that makes a lane change with autonomous travel control and then performing a second lane change for traveling along a set travel route, a determination is made as to whether or not a distance (D1) from a position at which the first lane change has concluded to a position at which the second lane change can be started is a predetermined distance or less. When a determination is made that the distance (D1) is the predetermined distance or less, a determination is made as to whether or not assistance with the autonomous lane change control is enabled for the second lane change. When a determination is made that the assistance with the autonomous lane change control is enabled, a determination is made as to whether or not a lane change can be made from a subject vehicle lane in which the vehicle travels to an adjacent lane that is adjacent to the subject vehicle lane. When a determination is made that the lane change from the subject vehicle lane to the adjacent lane can be made, the second lane change is made with the autonomous lane change control. When a determination is made that the lane change from the subject vehicle lane to the adjacent lane cannot be made, the driver is notified that the lane change with the autonomous lane change control cannot be made. When a determination is made that the assistance with the autonomous lane change control is not enabled, the driver is notified that the lane change with the autonomous lane change control cannot be made.
