Abstract
A travel control device acquires subject vehicle information including the position of a subject vehicle, acquires object information including the position of an avoidance object which the subject vehicle should avoid, plans a target route for avoiding the avoidance object in accordance with the position of the subject vehicle and the position of the avoidance object, and outputs command information for driving the subject vehicle on the target route. The planning function is used to reduce the distance from the subject vehicle to a turning point as a margin distance decreases. The margin distance is the distance between the subject vehicle and a lane marker on a road on which the subject vehicle is traveling and is along a width direction of the road. The turning point is a point at which the location of the target route along the width direction varies by a predetermined distance or more.
