1. A travel assistance method for a vehicle, the method comprising:
determining whether a route-following lane change along a set travel route can be assisted with autonomous lane change control;
in response to a determination that the route-following lane change can be assisted with the autonomous lane change control, autonomously controlling the vehicle to make the route-following lane change in a first direction; and
in response to a determination that the route-following lane change cannot be assisted with the autonomous lane change control, notifying a driver that the route-following lane change cannot be made with the autonomous lane change control, and prohibiting the autonomous lane change control from assisting a lane change in a second direction opposite to the first direction even in a case where an operation by the driver would otherwise cause the autonomous lane change control to assist with the lane change in the second direction.
