An autonomous travel controller detects whether a host vehicle is carrying out a first course change for changing a course in a direction indicated by a turn indicator. Upon detecting that the host vehicle is carrying out the first course change, detecting whether there is a road that enables a second course change for changing the course of the host vehicle that branches from the road after the first course change. When a road that enables the second course change is detected, the autonomous travel controller turns the turn indicator off.

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.

Lane recognition method and lane recognition device

A travel assistance method and device, when performing a first lane change with autonomous lane change control and then performing a second lane change for traveling along a set travel route, determines whether or not a distance from a position at which the first lane change has concluded to a position at which the second lane change can be started is a predetermined distance or less. When it is determined that the distance is the predetermined distance or less, whether assistance with the autonomous lane change control is enabled for the second lane change is determined. When assistance with the autonomous lane change control is enabled, whether a lane change can be made from a subject vehicle lane to an adjacent lane is determined. When the lane change to the adjacent lane can be made, the second lane change is made with the autonomous lane change control.

Vehicle travel assistance method and vehicle travel assistance device

A driving assistance method for performing a lane change of an own vehicle by autonomous travel control includes: calculating a target route along which the own vehicle is caused to travel to a destination; determining whether or not multiple lane changes are required to be performed successively for the own vehicle to travel in accordance with the target route; determining whether or not the lane change is performed by the autonomous travel control; and when a determination that, in a second or later lane changes among the multiple lane changes, a lane change is not performed by the autonomous travel control is included, not performing a first lane change by the autonomous travel control.

An autonomous speed control function for autonomously controlling a traveling speed of the vehicle and an autonomous steering control function for autonomously controlling steering of the vehicle include executing first autonomous control where, when an external situation of the vehicle is recognizable from a captured image by a camera on the vehicle, the vehicle is autonomously controlled using information recognized from the captured image; executing second autonomous control in which information indicating the external situation of the vehicle is acquired from stored map information provided in the vehicle and the vehicle is autonomously controlled using the acquired information; specifying an unrecognizable area in which the external situation of the vehicle is unrecognizable from the captured image; and when the unrecognizable area is present on a travel route of the vehicle, switching from the first autonomous control to the second autonomous control before the vehicle enters the unrecognizable area.

Vehicle travel control method and vehicle travel control device

A driving assist method executes a lane change assist based on a generated target travel route. Upon determining the host vehicle is traveling in a road having several lanes, an determination is made as to whether or not the host vehicle is traveling in a first area where an autonomous lane change can be executed. Next, upon determining that the host vehicle is traveling in the first area, an determination is made as to whether or not the host vehicle is traveling in a predetermined range from an area border, which is a boundary between the first area and a second area where the autonomous lane change cannot be executed. Upon determining the host vehicle is traveling in a predetermined range from the area border, a control for the autonomous lane change is performed so that the host vehicle travels in a traveling lane.

Driving assist method and driving assist device

A driving assist method is performed by a controller that performs a lane change assist based on a generated target route. A determination is made as to whether or not the lane change has been executed. Next, it determines whether or not the lane change is in a direction toward a preset location due to a driver's operation when the lane change has been executed. Then, a determination is made as to whether or not a position index value from the host vehicle to the preset location is equal to or less than a first threshold value when the lane change is in a direction toward the preset location due to the driver's operation. The lane change assist in a direction away from the preset location is restricted when the position index value is equal to or less than the first threshold value.

In a system trigger mode and a driver trigger mode, when a start condition for an automated lane change function by autonomous travel control is satisfied, lane change information as to whether to accept execution of the automated lane change function is presented; when an acceptance input of accepting the execution is detected, a determination is made as to whether the lane change is possible; and the automated lane change function is executed when it is determined possible. In the driver trigger mode, when a predetermined lane change instruction operation is performed, a determination is made as to whether the lane change is possible, and when a determination is made that lane change is possible, the automated lane change function is executed. The time for the lane change determination by the driver trigger mode is set shorter than the time for the lane change determination by the system trigger mode.

A system trigger mode and a driver trigger mode are provided. In the system trigger mode, when a start condition for an automated lane change function of performing a lane change of a vehicle by autonomous travel control is satisfied, lane change information as to whether or not to accept execution of the automated lane change function is presented, and when an acceptance input of accepting the execution of the automated lane change function is detected in response to presentation of the lane change information, the automated lane change function is executed. In the driver trigger mode, the automated lane change function is executed when a lane change instruction operation different from the acceptance input is performed. When the lane change instruction operation is performed after the presentation of the lane change information, the automated lane change function by the driver trigger mode is executed.

Vehicle travel control method and travel control device

A travel control method for a vehicle includes: presenting a vehicle traveling on a route to a preliminarily set destination with overtaking information as to whether to accept execution of an overtaking assist function for overtaking a preceding vehicle by changing lanes through autonomous travel control; and executing the overtaking assist function when an acceptance input of accepting the execution of the overtaking assist function is detected in response to presentation of the overtaking information. This method further includes: detecting a position of the vehicle on the route; and detecting whether or not there is a traveling direction change point on the route ahead of the position of the vehicle, a point at which the vehicle must change its traveling direction. When the distance from the vehicle to the traveling direction change point is shorter than a preliminarily set distance, the presentation of the overtaking information is not performed.

An automated lane change control detects a preceding vehicle that is traveling in a same travel lane as a host vehicle, determines whether a predetermined condition is satisfied between the host vehicle and the preceding vehicle, and executes an automated lane change in the host vehicle after a first predetermined time has elapsed from determining that the predetermined condition is satisfied. The automated lane change of the host vehicle is executed after a first predetermined time has elapsed after determining that the predetermined condition has been satisfied. A second predetermined time is set that is longer than the first predetermined time as a time for prohibiting the automated lane change upon assessing the presents of a previous driver lane change. The automated lane change is prohibited in an interval that starts when a prohibiting condition is satisfied and ends when the second predetermined time elapses.
