  • Publication number: 20200172100
    Abstract: This vehicle control device is provided with: a detection unit; and an external environment recognition unit that extracts a target object and left and right recognition lines of a traveling path. Additionally, a local environment map creation unit of the vehicle control device calculates an area of activity of an own vehicle and left and right border lines which indicate a limit of non-interference with the target object. Furthermore, the local environment map creation unit calculates left and right recommended border lines during traveling of the own vehicle by adding a margin interval that narrows the left and right border lines toward the inside.

  • Publication number: 20200086869
    Abstract: The present invention relates to a vehicle control device for automatically controlling at least a part of the drive control of the host vehicle. If an external condition detecting unit detects a first other vehicle subject to following control and a second other vehicle which exhibits the traveling movements of cutting in between the first other vehicle and the host vehicle, a deceleration limiter sets limits that differ depending on whether or not the relative speed of the host vehicle vis-a-vis the second other vehicle exceeds a speed threshold having a positive value.

  • Publication number: 20200057447
    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.

  • Publication number: 20200047753
    Abstract: In this vehicle control device, a low-level short-terra trajectory generating unit generates a short-term trajectory by using the newest dynamic external environment recognition information while also using the same static external environment recognition information (lane shape information, or the like) as the static external environment recognition information used by a high-level medium-term trajectory generating unit. Performing such control prevents inconsistency between the external environment information (environment information) used by the low-level short-term trajectory generating unit and that used for a medium-term trajectory, which is a high-level trajectory, and makes stable trajectory output possible.
