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.

Abstract: A lane change planning device has a processor configured to assess whether or not it has been planned to carry out multiple lane changes within a single road, based on a traveling lane plan that represents a lane on which a vehicle is scheduled to travel within a predetermined zone of a traveling route toward the destination location of the vehicle, and to create a lane change plan such that a first scheduled lane change zone that the vehicle has been assigned for a lane change to be carried out afterwards, is shorter than a second scheduled lane change zone that has been assigned for a lane change to be carried out beforehand, when it has been planned to carry out multiple lane changes within a single road.

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.

Abstract: A vehicle control device has a processor configured to assess whether or not a lane change is necessary based on a scheduled route and surrounding environment information for a vehicle and select a traffic lane of the road, to produce a driving lane plan showing the scheduled driving lane, determine the notification priority representing the priority for notifying the driver of the planned lane change, based on at least one item from among the scheduled route, and the result of assessing whether or not the planned lane change is included in a plurality of continuous planned lane changes to be executed for a common purpose, when it has been planned to execute a lane change and suppress notification to the driver of planned lane changes with low notification priority compared to notification to the driver of planned lane changes with high notification priority, using a notification unit.

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.

Abstract: An autonomous driving system controls autonomous driving of a vehicle and calculates an interest level of a driver of the vehicle for the autonomous driving. In a driver-oriented mode, the autonomous driving system gives priority to at least one of setting by the driver, will of the driver, and ride quality. In a performance-oriented mode, the autonomous driving system gives priority to at least one of increase in a safety margin, reduction in a time to arrive at a destination, improvement in fuel economy, improvement in motion performance, and reduction in a frequency of notification to the driver. The autonomous driving system controls the autonomous driving in the driver-oriented mode in a case of a normal state, and controls the autonomous driving in the performance-oriented mode in a case of a low interest state where the interest level is lower than the normal state.

Abstract: An autonomous driving system includes: a driver information acquisition device that acquires driver information indicating an action and a state of a driver of a vehicle; and a control device that performs autonomous driving control that controls autonomous driving of the vehicle. The autonomous driving control includes: deactivating action detection processing that detects, based on the driver information, a deactivating action of the driver to deactivate the autonomous driving; ready state detection processing that detects, based on the driver information, a ready state indicating that the driver is ready for manual driving; and deactivation processing that deactivates the autonomous driving when the ready state is detected after the deactivating action is detected.

Abstract: An autonomous driving system includes: an information acquisition device that acquires surrounding situation information indicating a surrounding situation around a vehicle; and a lane change control device that controls lane change of the vehicle. An influence degree represents influence of the lane change on traffic flow around the vehicle. The lane change control device performs: acceptable range setting processing that sets an acceptable upper limit of the influence degree as a function of a position along a travel lane in which the vehicle travels; influence degree calculation processing that calculates the influence degree based on the surrounding situation information; and lane change determination processing that prohibits the lane change when the influence degree is greater than the acceptable upper limit while executes the lane change when the influence degree is equal to or less than the acceptable upper limit.
