  • Patent number: 11932252
    Abstract: A vehicle control device has a processor configured to decide on standby time for waiting until a vehicle that is capable of automatic control for at least one vehicle operation from among driving, braking and steering is to begin the operation for the lane change, based on either first information indicating the degree to which the driver contributes to control of the vehicle or second information representing the extent to which manual control of the vehicle by the driver is possible, the greater the degree to which the driver contributes to control of the vehicle, represented by the first information, or the extent to which manual control of the vehicle by the driver is possible, represented by the second information, the shorter the standby time.

  • Patent number: 11920936
    Abstract: A vehicle controller determines whether the position of a detected travel lane relative to an edge of a road being traveled by a vehicle may differ from an actual position; estimates a first required time for an action, which is required before the vehicle reaches a predetermined location, for the case that the position of the detected lane relative to the edge of the road is correct; estimates a second required time for the action for the case that the position of the detected lane differs from the actual position by a predetermined number of lanes; and sets start timing of the action, based on the second required time, so that the action will finish before the vehicle reaches the predetermined location, when the position of the detected lane may differ from the actual position and the second required time is longer than the first required time.

  • Publication number: 20230418290
    Abstract: When a subject vehicle reaches a first position of an interflow zone within an interflow lane, it is judged whether a condition for automatic interflow is satisfied. When it is judged that the condition for automatic interflow is not satisfied at the first position, a notification for urging manual interflow by a driver is stated to execute. When it is judged that the condition for automatic interfiow is satisfied at the first position, the automatic interflow is stared to execute.

  • Publication number: 20230373535
    Abstract: A vehicle controller detects a travel lane on which a vehicle is traveling, and determines whether the position of the detected travel lane relative to an edge of a road may differ from an actual position. The vehicle controller further identifies first control of the vehicle required on the travel lane and second control of the vehicle required on an adjoining lane. The vehicle controller transfers control of the vehicle to a driver in the case where the position of the detected travel lane may differ from the actual position and where both the first control and the second control may compromise safety of the vehicle or prevent completion of a predetermined action to be completed before reaching a predetermined distance.

  • Patent number: 11703876
    Abstract: An autonomous driving system acquires information concerning a vehicle density in an adjacent lane that is adjacent to a lane on which an own vehicle is traveling, when the own vehicle travels on a road having a plurality of lanes. The autonomous driving system selects the adjacent lane as an own vehicle travel lane, when the vehicle density in the adjacent lane that is calculated from the acquired information is lower than a threshold density that is determined in accordance with relations between the own vehicle and surrounding vehicles. The autonomous driving system performs lane change to the adjacent lane autonomously, or propose lane change to the adjacent lane to a driver, when the adjacent lane is selected as the own vehicle travel lane.

  • Patent number: 11681290
    Abstract: When conditions have not been satisfied from a timing at which a first position of the interflow zone was set to a timing at which the subject vehicle reaches the first position, the first position is set as a start position where a notification for urging a handover of a central player of the subject vehicle is performed. When the condition for automatic interflow is satisfied for the first time at the timing at which the subject vehicle reaches the first position, a second position between the first position and a distal end of the interflow zone is set as the start position.

  • Patent number: 11623646
    Abstract: An autonomous driving system includes a lane change control device that performs lane change control for making a lane change from a first lane to a second lane during autonomous driving of a vehicle. The lane change control device is configured to: determine, from start to completion of the lane change control, whether or not a driver's operation is performed as an abort request operation that requests to abort the lane change control; when the abort request operation is performed, determine whether or not an abort permission condition is satisfied; when the abort permission condition is not satisfied, continue the lane change control; and, when the abort permission condition is satisfied, abort the lane change control and make the vehicle travel in the first lane. The lane change control device changes ease of satisfaction of the abort permission condition depending on the situation.
