  • Patent number: 11262753
    Abstract: In a vehicle control system, a control unit of the vehicle control system executes a stop process by which the vehicle is parked in a prescribed stop area when it is detected that the control unit or the driver has become incapable of properly maintaining a traveling state of the vehicle. In the stop process, the control unit determines a plurality of available stop areas according to the vehicle surroundings and map information, and computes, for each available stop area, a cumulative travel risk obtained by accumulating a travel risk involved in traveling from a position of the vehicle when the stop process is initiated to each available stop area and a stop risk in stopping in each available stop area, the control unit determining a final stop area by comparing the cumulative travel risk with the stop risk in each available stop area sequentially from the nearest one.

  • Patent number: 11142197
    Abstract: In this vehicle control device, a low-level short-term 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 (environmental 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.

  • Publication number: 20210284148
    Abstract: There is provided a travel control apparatus. A control unit executes, based on a recognition result of the division line by a recognition unit, first control to perform lane keeping of the self-vehicle. In a case in which the recognition result ceases to be satisfied a predetermined condition, the control unit will switch, at a first timing. Even in a case in which the recognition result ceases to be satisfied the predetermined condition, if the predetermined condition ceases to be satisfied due to a recognition result of a width of a travel lane of the self-vehicle, the control unit will switch the control to be executed from the first control to the second control at a second timing earlier than the first timing.

  • Publication number: 20210284236
    Abstract: A moving body control apparatus includes a cancel control section performing control to cancel a lane change when a first cancel condition and a second cancel condition for cancelling the lane change are satisfied. When the first cancel condition is satisfied with the grip of an occupant on a manipulator being a prescribed level or greater, if a distance in a vehicle width direction between a moving body and a lane marker is a first distance threshold value or greater, the cancel control section judges that the second cancel condition is satisfied and cancels the lane change, and when the first cancel condition is satisfied with the grip being less than the prescribed level, if the distance is not less than a second distance threshold value greater than the first distance threshold value, the cancel control section judges that the second cancel condition is satisfied and cancels the lane change.

  • Publication number: 20210284149
    Abstract: There is provided a travel control apparatus. A recognition unit recognizes a division line of a road on which a self-vehicle is traveling. A control unit executes lane maintenance control to perform lane maintenance of the self-vehicle based on a recognition result of the division line by the recognition unit. If the recognition unit has become unable to recognize the division line in a case in which a first control state for executing the lane maintenance control without issuance of a steering wheel gripping request is set, the control unit will allow preceding vehicle following control, for following a preceding vehicle of the self-vehicle, to be executed after switching the lane maintenance control to manual driving.
