VEHICLE TRAVEL CONTROL METHOD AND TRAVEL CONTROL DEVICE

A travel control method for executing autonomous lane change control of a vehicle (Vo) is provided. This method 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, in response to presentation of the first lane change information, a first acceptance input made by the driver indicating that the driver accepts the execution of the autonomous control of the successive lane changes, executing first autonomous lane change control; after executing the first autonomous lane change control, 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, in response to presentation of the second lane change information, a second acceptance input made by the driver indicating that the driver accepts the execution of the autonomous lane change control after the first lane change, 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.
