  • Publication number: 20210276559
    Abstract: On a road on which a first lane, a second lane, and a third lane or a road shoulder are adjacent to each other, a vehicle control device executes an automatic lane change from the first lane to the second lane. In the case that a traffic regulating object that regulates passage of traffic in the third lane or on the road shoulder is placed in the third lane or on the road shoulder, and an external environment recognition unit recognizes the traffic regulating object, a lane change control unit restricts the automatic lane change.

  • Publication number: 20210276558
    Abstract: A lane change control unit restricts an automatic lane change in the case of predicting that a user's own vehicle after having made the automatic lane change will be adjacent to another vehicle that exists inside of a third lane or on a third lane dividing line, and executes the automatic lane change without restriction in the case of predicting that the user's own vehicle after having made the automatic lane change will be adjacent to another vehicle that exists inside a fourth lane or inside of a road shoulder.

  • Patent number: 11097734
    Abstract: A vehicle control device includes: an operation detection unit that detects an operation input of a user for an operation input unit; a speed setting unit that sets travel speed of a host vehicle on the basis of the operation input that is detected by the operation detection unit; and a lane change control unit that controls lane change. If the operation input that decreases, by more than or equal to a predetermined degree, setting travel speed that is the speed set by the speed setting unit, or the operation input that decreases the setting travel speed to be lower than current travel speed of the host vehicle, is performed after the lane change is started, the lane change control unit cancels the lane change.

  • Patent number: 11059486
    Abstract: A vehicle control unit includes: a lane change control unit that performs lane change control in which a host vehicle changes lanes on the basis of a surrounding situation of the host vehicle; and a lane change control suppression unit that allows the lane change control in a case where there is no operation history indicating that an operation of a notification unit for notifying a direction to which a traveling direction of the host vehicle is changed is not normal, and suppresses the lane change control in a case where the operation history indicating that the operation of the notification unit is not normal is present.

  • Patent number: 11054833
    Abstract: In the present invention, automated driving control of a vehicle during automated driving is fundamentally performed by referring to a medium-term trajectory which is generated in a medium period having a relatively long computation period and in which emphasis is placed on the smoothness of driving behavior changes. As an exception, in cases in which reference-excluding conditions are matched, the medium-term trajectory is ignored, and automated driving control of the vehicle is performed using only a short-term trajectory generated in a short period having a shorter computation period than the medium period. Thus, a vehicle control device is provided which ensures adaptability without diminishing responsiveness.

  • Patent number: 11027728
    Abstract: An integrated object formation unit of a vehicle control device forms integrated objects, which are integral objects, the boundaries of the integrated objects being determined from the positional relationship between two or ore objects in a prescribed distance range. An interference prediction unit of the vehicle control device predicts the probability of the integrated objects, instead of each of the objects, coming into contact with, or near, a vehicle.

  • Publication number: 20210101600
    Abstract: A vehicle control device includes: a recognizer configured to recognize surrounding conditions of a host vehicle; a driving controller configured to control one or both of speed and steering of the host vehicle on the basis of the surrounding conditions recognized the recognizer; and an outside notifier configured to notify an outside of the host vehicle of a lane change destination of the host vehicle. The driving controller is configured to change a time or a distance until lane change from a host vehicle travel lane in which the host vehicle is traveling to a neighboring lane which is adjacent to the host vehicle travel lane is stopped depending on whether the outside of the host vehicle is notified of the lane change destination by the outside notifier when stopping conditions of the lane change are satisfied at the time of starting of the lane change.

  • Patent number: 10946872
    Abstract: In the present invention, a short-term route (provided at a timing for starting automatic driving) for automatic driving control that uses local environment map information generated constantly by a local environment map generation unit is generated continuously even when automatic driving is not set to an on state by an automatic driving switch. As a result, it is possible to instantly control the automatic driving of a vehicle by the continuously generated short-term route after transitioning to the on state of the automatic driving switch.
