  • Publication number: 20220307842
    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: 20220113735
    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.

  • Publication number: 20220075374
    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 a handover of a central player of the subject vehicle is stated to execute. When it is judged that the condition for automatic interflow is satisfied at the first position, the start of the execution of the notification is temporarily suspended.

  • Patent number: 11215992
    Abstract: When a subject vehicle reaches a position PNO in a middle of an interflow zone, it is judged whether conditions for automatic interflow are satisfied. When it is judged that the conditions for automatic interflow are not satisfied at the position PNO, a notification for urging manual interflow by a driver is started. Otherwise, the notification for manual interflow is not started. In a case where the notification for manual interflow was not started, when the subject vehicle reaches the position PGU between a distal end of an interflow zone and the position PNO, the notification for manual interflow is started.

  • Patent number: 11091170
    Abstract: An autonomous driving system issues an operation instruction to a driver of a vehicle during autonomous driving. The operation instruction is an instruction that makes a request or a proposal to the driver and urges the driver to perform a response operation responding to the request or the proposal. An attention desire degree is a degree of the driver's desire to pay attention to a situation surrounding the vehicle, and an attention event is an event that increases the attention desire degree. A delay condition is that the attention desire degree exceeds a threshold or the attention event exists. When the operation instruction is necessary and the delay condition is satisfied, the autonomous driving system performs delay processing that waits without issuing the operation instruction. When a delay end condition is satisfied after start of the delay processing, the autonomous driving system issues the operation instruction.

  • Publication number: 20210245760
    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.
