VEHICLE TRAVEL CONTROL METHOD AND VEHICLE TRAVEL CONTROL DEVICE

A travel control method for a vehicle having an autonomous travel control function, comprising: detecting an oncoming vehicle (V2) travelling in the opposite lane (L2) of the travel lane (L1) in which the subject vehicle (V1) travels; predicting whether or not the oncoming vehicle (V2) enters into the travel lane (L1) in which the subject vehicle (V1) travels; when it is predicted that the oncoming vehicle (v2) enters into the travel lane (L1) in which the subject vehicle (V1) travels, setting initial deceleration of the subject vehicle (V1) in a case of time until the subject vehicle (V1) and the oncoming vehicle (V2) 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 (V1).
