1. A travel assistance method for a vehicle using a processor that executes autonomous lane change control based on a travel route to a destination acquired from a navigation device, the processor operating to:
when performing a first lane change with the autonomous lane change control and then performing a second lane change for traveling along the travel route, determine whether or not a distance 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;
determine whether or not assistance with the autonomous lane change control is enabled for the second lane change;
when determining that the assistance with the autonomous lane change control is not enabled for the second lane change, unless the distance is the predetermined distance or less, not perform the second lane change with the autonomous lane change control and not notify a driver that a lane change with the autonomous lane change control cannot be made; and
even when determining that the assistance with the autonomous lane change control is not enabled for the second lane change, when determining that the distance is the predetermined distance or less, not perform the second lane change with the autonomous lane change control and notify the driver that the lane change with the autonomous lane change control cannot be made.
