Vehicle Travel Control Method and Travel Control Device

A travel control method for executing autonomous lane change control of a vehicle includes, before performing two or more successive lane changes, presenting the driver with first lane change information as to whether or not to accept execution of autonomous control of the successive lane changes; when detecting a first acceptance input made by the driver indicating that the driver accepts the execution of the autonomous control, executing first autonomous lane change control; then presenting the driver with second lane change information as to whether or not to accept execution of the autonomous lane change control after the first lane change; and when detecting a second acceptance input made by the driver, executing the autonomous lane change control after the first lane change. An action load of the second acceptance input is set smaller than an action load of the first acceptance input.
