A vehicle control method as executed includes acquiring surrounding information of the subject vehicle by a sensor includes, specifying an entry position located on a second lane adjacent to a first lane where the subject vehicle travels in accordance with the surrounding information of the subject vehicle, specifying a front vehicle located front the entry position and a rear vehicle located rear the entry position, determining the travel state of each of the front vehicle and the rear vehicle, determining whether there is a space for the subject vehicle to enter at the entry position, predicting whether the front vehicle starts to travel when the front vehicle and the rear vehicle are determined to be stopped and no space is determined at the entry position, and starting to move the subject vehicle to the entry position when the front vehicle is predicted to start traveling.

A lane information management method for managing lane information using a processor is provided. This method includes acquiring road map information and information on a travel history that is represented by a travel trajectory on a road map, determining, using a plurality of the travel histories, whether or not a lane connected to an intersection is in a multiple lane form in which two or more lines of vehicles are formed on a single lane, and managing the lane information, including a result of determination of the multiple lane form in the lane information.

A vehicle control method for executing a lane change of a subject vehicle includes acquiring surrounding information of the subject vehicle; specifying an entry position indicating a position of an entry destination of the subject vehicle, the entry position being located on a second lane adjacent to a first lane in which the subject vehicle is traveling; when operating a blinker, decelerating the subject vehicle, and executing a lane change; determining that there is a following vehicle which follows the subject vehicle in a predetermined area located behind the subject vehicle on a first lane; setting a preparation time longer than the preparation time when determining that there is not the following vehicle, the preparation time indicating a time from operating the blinker to decelerating the subject vehicle and starting the lane change; and controlling a travel position of the subject vehicle on the first lane within the preparation time.

A controller performs: trajectory generation processing of generating a target travel trajectory in such a way that, when a distance between a turning position of an own vehicle and a parked vehicle satisfies a predetermined condition, the own vehicle passes beside the parked vehicle at a predetermined side position with a predetermined interval interposed between the parked vehicle and the own vehicle on one side of the parked vehicle and a turning end position in a case of turning at a position before a position of the parked vehicle or a turning start position in a case of turning after having passed beside the parked vehicle on the route coincides with the predetermined side position in a width direction of a road on which the parked vehicle is parked; and processing of performing travel control, based on the target travel trajectory.

A pedestrian crosswalk through which a subject vehicle is expected to pass is specified as a target pedestrian crosswalk. Road configurations close to the target pedestrian crosswalk are detected. Traffic lines of moving objects crossing the target pedestrian crosswalk are estimated on the basis of the road configurations. An area including the estimated traffic lines is set as a detection area of a detector detecting objects around the subject vehicle. The moving objects are detected by the detector in the detection area. Travel of the subject vehicle is controlled on the basis of a detection result of the detector.

Method for controlling travel of vehicle, and device for controlling travel of vehicle

A method of storing a travel history uses a controller to store the travel history of a vehicle in a storage device for each link of a traveling path. The method includes determining that one or more travel histories in a link are one type or two or more types of travel histories on the basis of a predetermined determination condition and storing the two or more types of travel histories in the link in the storage device so as to be sorted for the determined two or more types.

A driving assistance method includes extracting an interference traffic line that is a route along which another vehicle can move and that interferes with a planned travel route of a subject vehicle. The method also includes determining a necessary length of the extracted interference traffic line of the other vehicle, which length is necessary for determining a driving action of the subject vehicle, on the basis of at least one of a shape of a road, a traffic rule, and a traffic situation. The method further includes determining the driving action of the subject vehicle to respond to the other vehicle moving along the interference traffic line using a range of the determined necessary length of the interference traffic line as a determination object.

Driving assistance method and device

A driving assistance apparatus comprises a processor for: determining whether or not a preceding vehicle is traveling outside an area including an intersection and vicinities of the intersection; when the preceding vehicle is traveling outside the area, determining whether or not a direction indicator of the preceding vehicle on a road shoulder side is lighting; and when the direction indicator is lighting, performing second driving assistance different from first driving assistance for following the preceding vehicle.

Driving assistance device and driving assistance method

A driving assistance method of causing a host vehicle to travel by following a preceding vehicle includes: determining whether the preceding vehicle of the host vehicle is present or absent and, upon determining that the preceding vehicle is present, performing a preceding vehicle type determination of determining whether the preceding vehicle of the host vehicle is a four-wheeler or a two-wheeler; upon the preceding vehicle being a four-wheeler, performing both a control of inter-vehicle distance to the four-wheeler and a route following based on the four-wheeler; and upon the preceding vehicle being a two-wheeler, performing a control of inter-vehicle distance to the two-wheeler without performing a route following based on the two-wheeler.

A drive planning processor plans a driving operation plan for a subject vehicle traveling on a route. The drive planning processor determines an action for each of a plurality of events which the subject vehicle encounters in a time-series manner when traveling on a first route and plans a series of driving operation plan for a scene which the subject vehicle encounters using content of each action determined for each of the plurality of events.

An extension process of extending an area of at least one of the first pedestrian crosswalk and the second pedestrian crosswalk is performed. When a determination is made that at least a part of the first pedestrian crosswalk and the second pedestrian crosswalk overlap each other, an area including the first pedestrian crosswalk and the second pedestrian crosswalk is set as a detection area of a detector detecting an object around the subject vehicle. A moving object is detected in the detection area using the detector. Travel of the subject vehicle is controlled on the basis of a detection result of the detector.

A scene determination device includes a determination configured to, when determining a driving action of a subject vehicle traveling on a route, determine a scene which the subject vehicle encounters. The determination processor extracts a plurality of events which the subject vehicle traveling on a first route encounters, on the basis of relationships between the first route on which the subject vehicle travels and second routes having points of intersections with the first route and determines the scene using a relationship between each of the extracted events and the subject vehicle.
