Abstract
A travel control method for a vehicle detects a target trajectory along which a subject vehicle should travel and controls the subject vehicle to travel in an autonomous manner along the detected target trajectory. This method includes provisionally setting a forward gaze point distance from the subject vehicle to a forward gaze point, estimating a traveling trajectory in which the subject vehicle coincides with the target trajectory at the forward gaze point, detecting a maximum value of a lateral displacement between the estimated traveling trajectory and the target trajectory during travel from a current position of the subject vehicle to the forward gaze point, and definitely setting the forward gaze point distance when the maximum value of the lateral displacement is a predetermined value or less as an actual forward gaze point distance and controlling the subject vehicle to travel on the basis of the definitely-set forward gaze point distance.
