A driving assistance method for performing a lane change of an own vehicle by an automated lane change function causes a controller to perform processing including: when a vehicle permitted to travel in, of a first lane and a second lane, the first lane is limited, the first lane and the second lane being a plurality of lanes on a road on which the own vehicle travels, the plurality of lanes being adjacent to each other and having a same travel direction, determining whether or not the own vehicle is traveling in the first lane in which a vehicle permitted to travel in the first lane is limited; and when determining that the own vehicle is traveling in the first lane, not performing a lane change from the first lane to the second lane by the automated lane change function.

Driving assistance method and driving assistance device for performing a lane change

A controller: determines whether a current position of an own vehicle is within a high-definition map-available region in which high-definition map information is available; when the current position is within the map-available region, performs acceleration/deceleration of the own vehicle, based on specified speed information acquired by recognizing a speed sign in a captured image or acquired from the high-definition map information and also notifying a driver of the specified speed information; and when the own vehicle is predicted to leave the high-definition map-available region, terminates the acceleration/deceleration control based on the specified speed information and also acquires specified speed information from road map information, the road map information having lower precision than the high-definition map information, based on the current position of the own vehicle and notifies the driver of the acquired specified speed information before a point at which the own vehicle leaves the map-available region.

Vehicle control method and vehicle control device

A processor determines whether a construction related item has been detected or not ahead of a subject vehicle based on vehicle surrounding information obtained by a sensor and determines that a point separated by a predetermined distance ahead of the subject vehicle from the construction related item is an end point of the road construction section when determining that the construction related item has been detected. The predetermined distance when the construction related item is detected and another vehicle is not detected around the detected construction related item is shorter than the predetermined distance when the construction related item is detected and the other vehicle is detected around the detected construction related item.

Construction zone determining method and construction zone determining device

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.
