A vehicle travel control method including: determining whether or not a target travel route of a vehicle traveling on a first road is a route leading to a second road, the second road branching off from the first road; when the target travel route is a route leading to the second road, calculating a first trajectory linking a branch point at which a second link representing a lane shape of a second lane on the second road, branches off from a first link representing a lane shape of a first lane on the first road, and a point on the second link, the point being located a predetermined distance away from the branch point along the second link, and setting a target travel trajectory, based on the first trajectory; and controlling the vehicle to travel along the target travel trajectory.

Vehicle travel control method and vehicle travel control device

A driving assistance method uses a controller to perform automated lane change to control the own vehicle in such a way that the own vehicle makes a lane change under a condition that the passenger is at least in contact with the steering wheel, the driving assistance method causing the controller to perform processing including: selecting a target lane; and when automated lane change from a current lane to the target lane includes a first automated lane change from a first lane to a second lane and a second automated lane change from the second lane to a third lane, performing lane-keeping assistance under a condition that the passenger is at least in contact with the steering wheel from an end of control of the first automated lane change until a start of control of the second automated lane change.

Driving assistance method and driving assistance device

A vehicle travel assistance method and a travel assistance device for a vehicle include determining whether or not a route-following lane change that is a lane change for traveling along a set travel route can be assisted with autonomous lane change control, and when determining that the route-following lane change cannot be assisted with the autonomous lane change control, notifying a driver that a lane change with the autonomous lane change control cannot be made, and prohibiting the autonomous lane change control from assisting a lane change in a direction opposite to a direction in which the vehicle moves during the route-following lane change.

Travel assistance method and travel assistance device for vehicle

A lane recognition method and a lane recognition device operate such that when a travel lane of a vehicle is recognized by performing cross-check between first boundary information about a boundary dividing lanes acquired from map information and second boundary information about the boundary dividing the lanes acquired from a detection device of the vehicle, a movable center line is detected from at least one of the first boundary information and the second boundary information. The movable center line is a center line that can move in a width direction of a road on which the vehicle travels. When the movable center line is detected, the cross-check between the first boundary information and the second boundary information is not performed on one of a right side and a left side of the vehicle on which the movable center line is detected.
