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.

A self-location estimation method includes detecting a traffic sign in a vicinity of a vehicle; determining a current location of the vehicle; acquiring height information of the detected traffic sign from map data in which two-dimensional coordinate information and height information of a traffic sign existing in a vicinity of a road are recorded, based on a relative location of the detected traffic sign with respect to the vehicle and the current location; and estimating a height at which the vehicle is present according to the height information acquired from the map data.

A vehicle control method executed by a processor for controlling a subject vehicle includes: acquiring, from a sensor for detecting a state of surroundings of the subject vehicle, detection data of another vehicle traveling in an adjacent lane adjacent to a travel lane in which the subject vehicle is traveling, and setting, on the adjacent lane, a target point for the subject vehicle to change a lane from the travel lane to the adjacent lane based on a position relationship between the subject vehicle and the other vehicle, specifying the other vehicle that is located behind the target point as a rear vehicle, and starting blinking of the direction indicator of the subject vehicle when a rear end of the subject vehicle is located ahead of the front end of the rear vehicle.

A driving assist method reduces a possibility of missing an opportunity to correct a host vehicle position set on map data. In the driving assist method using a controller that sets a target inter-vehicular distance from a host vehicle to a preceding vehicle, whether there is a request to execute a correction of a host vehicle position set on electronic map data is determined based on a result of comparing position information on a road sign described on the electronic map data with position information on the road sign acquired by using a camera installed in the host vehicle. If an execution request has not been made, the target inter-vehicular distance is set to a preset first target inter-vehicular distance. If an execution request has been made, the target inter-vehicular distance is set to a second target inter-vehicular distance, which is longer than the first target inter-vehicular distance.

A self-position correction method and/or a self-position correction device use a coordinate of the axis parallel to a front-rear direction of a vehicle as a longitudinal coordinate, calculate a corrected vehicle speed by adding a vehicle speed to a correction amount set based on a longitudinal correction amount obtained by subtracting a value of the longitudinal coordinate of a position of a target object detected by a detection unit from a value of the longitudinal coordinate of a position of a target object registered on a map data, and correct a position of the vehicle on the map data by estimating a position of the vehicle based on sequential integration of a calculated movement amount of the vehicle based on the corrected vehicle speed and a yaw rate of the vehicle.

An autonomous driving control method carried out by an autonomous driving control system having an autonomous driving control unit that executes an autonomous driving control for causing a host vehicle to travel along a target travel route generated on a map, comprising setting one or a plurality of target passage gates through which the host vehicle is scheduled to pass during passage through a toll plaza, determining the presence or absence of a preceding vehicle that has the predicted passage gate that matches the target passage gate of the host vehicle from among a plurality of preceding vehicles, and carrying out following travel using the preceding vehicle that has the predicted passage gate that matches the target passage gate as a follow target.

A direction indicator control unit obtains a position of an entry road and a position of an exit road of a roundabout determined to be present on a presumed traveling route of a vehicle, and determines a necessity of directional indication when entering the roundabout in accordance with a relationship between the position of the entry road and the position of the exit road.

Direction indicator control method and direction indicator control device

A direction indicator control unit inhibits direction indicators of a host vehicle from making a directional indication when the host vehicle enters a roundabout determined to be present along a presumed traveling route on which the host vehicle is presumed to travel. A direction indicator control method also inhibits direction indicators.

A travel-lane determination unit determines whether a vehicle is going to enter a traffic lane on which a toll booth is provided. After it is determined that the vehicle is going to enter the traffic lane, a travel control unit stops the vehicle at a position before the toll booth in a travel direction of the vehicle.

Vehicle travel control method and vehicle travel control device

A travel-lane determination unit determines whether a vehicle has entered a traffic lane on which a toll booth is provided. After it is determined that the vehicle has entered the traffic lane, a travel control unit pulls the vehicle to a position shifted from the center of the traffic lane toward the toll booth in a traffic-lane width direction, by the time when the vehicle reaches the toll booth.

In lane selection control in which a lane in which a host vehicle travels is selected based on the map information and information acquired by an external sensor that acquires periphery information of the host vehicle, a self-position correction object in an intended travel route is identified based on the map information. When the host vehicle reaches a correction point where the self-position correction object is present, a determination is made as to whether or not the self-position correction object can be recognized by the external sensor from the lane in which the host vehicle travels. Upon determined that the self-position correction object cannot be recognized from the center lane in which the host vehicle travels, a lane change to a leftmost lane where the self-position correction object can be recognized is made before the host vehicle reaches the correction point.
