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: 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 mounted on a vehicle includes: a vehicle behavior control device configured to perform vehicle behavior control that controls behavior of the vehicle; and an awareness level calculation device configured to calculate an awareness level of a driver of the vehicle. A low awareness state is a state where the awareness level is lower than a normal state. The vehicle behavior control device performs the vehicle behavior control such that another vehicle around the vehicle predicts or recognizes the behavior of the vehicle more easily in a case of the low awareness state than in a case of the normal state.

Abstract: The lane change intention discrimination portion executes intention discrimination processing when it receives from the vehicle control ECU an instruction for controlling the blinker. The intention discrimination processing is processing to discriminate what type of pattern for the lane change operation was demanded in the instruction for controlling the blinker. The start and exit timing setting portion executes timing setting processing based on a discrimination result of the intention discrimination processing. The timing setting processing is processing to set a start timing and an exit timing of the lighting operation of the blinker.

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. From start to completion of the lane change control, the lane change control device determines whether or not a driver's operation is performed as an abort request operation that requests to abort the lane change control. Specifically, the lane change control device: calculates abort necessity level indicating necessity to abort the lane change control, based on driving environment information indicating driving environment for the vehicle; sets criterion for determination such that the criterion becomes more easily satisfied as the abort necessity level increases; and when the driver's operation satisfies the criterion for determination, determines that the driver's operation is performed as the abort request operation.

Abstract: A traveling lane planning device has a processor configured to determine whether or not a branching terrain exists that has a first lane and a second lane adjacent to the first lane wherein the first lane branches into a third lane and a fourth lane at a branching start location in the traveling direction of the vehicle within a driving zone, when the branching terrain exists and the vehicle is located before the branching start location, to acquire lane movement information for movement between the first lane and second lane came off in the past, and based on the lane movement information, to select one lane from among the third lane and fourth lane as the lane to be taken at the branching start location and generate a traveling lane plan that indicates a scheduled traveling lane for traveling of the vehicle in the driving zone.

Abstract: A vehicle control device has a processor configured to determine whether a first road exists where the vehicle is to exit from the traveling road, and when a first road exists, to set a lane change schedule zone based on a first connecting location, to determine whether a second road located on the same side of the traveling direction of the vehicle as the first road exists between the current location of the vehicle and the first connecting location, to change a start location of the lane change schedule zone based on a second connecting location, when a second road exists and the start location of the lane change schedule zone is at a second connecting location, or before the second connecting location, and to notify the driver of the plan to move the vehicle between lanes while the vehicle is traveling in the lane change schedule zone.

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.

Abstract: An autonomous driving system includes: a Human Machine Interface; and a control device configured to control autonomous driving of a vehicle, present a first operation instruction to a driver of the vehicle during the autonomous driving, the first operation instruction requesting the driver to perform a first response operation performed in response to a first request or a first proposal by presenting the first request or the first proposal to the driver via the Human Machine Interface, and prohibit presenting a second operation instruction different from the first operation instruction until the first response operation is completed or until a timing at which the first response operation is predicted to be completed, the second operation instruction requesting the driver to perform a second response operation performed in response to a second request or a second proposal by presenting the second request or the second proposal.

Abstract: A passing restraint flag for restraining a host vehicle from passing a preceding vehicle ahead is established by a passing restraint determination unit of the vehicle control device. In addition, when the passing restraint flag is established, a traveling plan for the host vehicle not to pass the preceding vehicle ahead is generated by a traveling plan generation unit of the vehicle control device. The passing restraint determination unit establishes the passing restraint flag when there is the possibility of an inappropriate operation of passing occurring such as when a distance between a merging point of a traveling lane along which the host vehicle travels and a merging lane merging into the traveling lane, and a position of the preceding vehicle having passed through the merging point is equal to or less than a third threshold.
