Vehicle Travel Control Method and Vehicle Travel Control Device

A travel control method for a vehicle having an autonomous travel control function includes: detecting an oncoming vehicle travelling in the opposite lane of the travel lane in which the subject vehicle travels; predicting whether or not the oncoming vehicle enters into the travel lane in which the subject vehicle travels; when it is predicted that the oncoming vehicle enters into the travel lane in which the subject vehicle travels, setting initial deceleration of the subject vehicle in a case of time until the subject vehicle and the oncoming vehicle pass each other being relatively long to a smaller value than the initial deceleration in a case of the time being relatively short, and executing deceleration travel control of the subject vehicle.
