Vehicle control device and vehicle control method

Abstract

To enable suppressing the deterioration of convenience during automatic driving with no monitoring obligation.SOLUTION: The vehicle controller comprises: a guidance presence / absence determination unit 103 configured to determine whether or not an own vehicle is performing occupant-set-route guidance that is guidance for a route to a destination that is set by an occupant of the own vehicle; and a notification control unit 100 configured to cause to perform, at a predetermined timing, attention attracting notification upon the guidance presence / absence determination unit 103 determining, during automatic driving with no monitoring obligation, that the own vehicle is not performing the occupant-set-route guidance, wherein the attention attracting notification is at least one of confirmation notification for prompting confirmation relating to setting of the route, and state notification for notifying of a traveling state.SELECTED DRAWING: Figure 2

Claims

1. A vehicle control device that can be used in vehicles that perform autonomous driving without monitoring obligations, which is autonomous driving without the obligation to monitor the surroundings, A guidance status determination unit (103) that determines whether or not the vehicle is providing route guidance to a destination set by the occupants of the vehicle, The system includes a notification control unit (100, 100a, 100b, 100f, 100g, 100h) that, when the vehicle is in the state of automatic driving without monitoring obligations and the guidance presence / absence determination unit determines that it is not currently providing route guidance, causes the system to issue a notification at a predetermined timing, which is a notification that prompts confirmation related to route setting and a status notification that informs the driving status. The notification control unit (100h) is configured to, when the vehicle is in the state of automatic driving without monitoring obligation, perform a non-route guidance transition, which is a transition from a state in which route guidance is being performed to a state in which route guidance is not being performed, as a confirmation notification, and to perform a notification to confirm whether or not automatic driving without monitoring obligation is continuing. The vehicle is equipped with a repetition identification unit (104) that identifies whether or not it is traveling on a route that it has traveled on a predetermined number of times or more in the past. The aforementioned notification control unit, even if the guidance presence / absence determination unit determines that the vehicle is not currently providing route guidance during the vehicle's automated driving without monitoring obligations, will not issue the alert notification at the predetermined timing if the repetition determination unit determines that the vehicle is traveling on a route that it has traveled repeatedly in the past.

2. A vehicle control device according to claim 1, A vehicle control device comprising a continuation determination unit (109) that determines whether to continue the unsupervised automatic driving when the vehicle transitions to non-route guidance during the unsupervised automatic driving of the vehicle, in accordance with at least one of the driver's operations related to a second task which is an act other than driving permitted to the driver of the vehicle, and the driver's steering operations.

3. A vehicle control device according to claim 2, The continuation determination unit determines to continue the automated driving without monitoring duty if the driver performs an operation related to the second task, and continues the automated driving without monitoring duty if the driver performs a steering operation, and determines not to continue the automated driving without monitoring duty, and transitions to a driver change.

4. A vehicle control device according to any one of claims 1 to 3, The notification control unit is a vehicle control device that, when the vehicle is in the state of automatic driving without monitoring obligations, and the guidance presence / absence determination unit determines that it is not in the state of route guidance, causes the notification to be issued at a predetermined timing, which is the time when the elapsed time from the start of the state of automatic driving without monitoring obligations reaches a predetermined time.

5. A vehicle control device according to any one of claims 1 to 3, The notification control unit, when the vehicle is in the state of automatic driving without monitoring obligation, determines that the guidance presence / absence determination unit is not in the state of route guidance, and causes the notification control unit to issue the alert notification at a predetermined timing, which is the distance timing at which the vehicle has traveled since the start of automatic driving without monitoring obligation has reached a predetermined distance.

6. A vehicle control device according to any one of claims 1 to 3, The notification control unit, when the vehicle is in the state of automatic driving without monitoring obligation, determines that the guidance presence / absence determination unit is not in the state of route guidance, causes the notification control unit to notify information of predetermined points that the vehicle is scheduled to pass as status notification at predetermined time intervals from the start of the state of automatic driving without monitoring obligation, as a predetermined timing.

7. A vehicle control device according to any one of claims 1 to 3, The notification control unit is a vehicle control device that, when the vehicle is in the state of automatic driving without monitoring obligation, and the guidance presence / absence determination unit determines that it is not in the state of route guidance, causes the notification to be issued at a predetermined timing, which is the timing when the vehicle reaches a predetermined location, which is a predetermined area or point.

8. A vehicle control device according to claim 7, The system includes a speed control instruction unit (108) that, when the distance between the vehicle and the predetermined location falls below a threshold, causes the vehicle's speed to be reduced to a specified value or less. The notification control unit (100f) is a vehicle control device that, when the vehicle is in the state of automatic driving without monitoring obligation, and the guidance presence / absence determination unit determines that it is not in the state of route guidance, causes the vehicle to perform the status notification at the timing of when the vehicle reaches the predetermined location.

9. A vehicle control method that can be used in vehicles that perform autonomous driving without monitoring obligations, which is autonomous driving without the obligation to monitor the surroundings, Run by at least one processor, A process to determine whether or not the vehicle is currently providing route guidance to a destination set by the occupants of the vehicle, During the automated driving of the vehicle without the obligation to monitor, if the guidance presence / absence determination process determines that the vehicle is not currently providing route guidance, the vehicle includes a notification control process that causes the vehicle to issue a notification at a predetermined timing, which is at least one of a confirmation notification prompting confirmation related to route setting and a status notification informing of the driving status. In the notification control process, when the vehicle is in the state of automatic driving without monitoring obligation, if a transition to a non-route guidance transition occurs, which is a transition from a state identified as being in route guidance in the guidance presence / absence determination process to a state identified as not being in route guidance, at least one of the following is performed: a setting prompt notification prompting the setting of a destination as a confirmation notification, and a notification confirming whether or not automatic driving without monitoring obligation will continue. This process also includes a repetitive identification step to determine whether the vehicle is currently traveling on a route that it has previously traveled on more than a predetermined number of times. In the notification control step, even if the guidance presence / absence determination step determines that the vehicle is not currently providing route guidance while the vehicle is in automatic driving mode without monitoring obligations, if the repetition determination step determines that the vehicle is traveling on a route that it has traveled repeatedly in the past, the vehicle control method prevents the notification from being made at the predetermined timing.
