Method for Controlling Travel and Device for Controlling Travel of Vehicle

In a travel control method for a vehicle in which a certain target inter-vehicle distance is set from among a plurality of settable target inter-vehicle distances and a subject vehicle is controlled to follow, in an automated or autonomous manner, a traveling trajectory of a preceding vehicle traveling ahead of the subject vehicle, when a trajectory-following travel mode for following the traveling trajectory of the preceding vehicle in the automated or autonomous manner transitions from an OFF state to an ON state, the target inter-vehicle distance between the subject vehicle and the preceding vehicle is set to a relatively small value from among the settable values.
