Abstract

Provided is an automatic driving control device advantageous for a vehicle or the like in which a route can be changed during movement to a destination. An automatic driving control device, wherein a navigation device is provided with a route generation unit for generating a second route which is difference from a first route on the basis of predetermined conditions, and a determination unit for determining whether to change from the first route to the second route when an automatic driving permissible interval included in the second route is different from the automatic driving permissible interval included in the first route. When the route has been determined by the determination unit to be changeable from the first route to the second route, a control unit executes an automatic driving mode in the automatic driving permissible interval included in the second route.

First claim

What is claimed is:

1. An automated driving control device comprising:
a navigation device configured to store a road map and an automated driving allowed section on the road map, and configured to set a first route to a destination including the automated driving allowed section on a basis of a current position of a vehicle; and
one or more first processors functioning as an automated driving mode control unit configured to perform an automated driving mode in which acceleration/deceleration and steering of the vehicle are automatically controlled in the automated driving allowed section included in the first route,
wherein the navigation device comprises one or more second processors functioning as:
a route generation unit configured to generate a second route which is different from the first route on a basis of a predetermined condition; and
a route change determination unit configured to determine whether it is possible to change the first route to the second route in a case that the automated driving allowed section included in the second route is different from the automated driving allowed section included in the first route,
wherein in a case that route change determination unit has determined that it is possible to change the first route to the second route, the automated driving mode control unit is configured to perform the automated driving mode in the automated driving allowed section included in the second route,
wherein the one or more first processors function as a mode changing unit configured to facilitate changing from the automated driving mode to a manual driving mode where an occupant of the vehicle performs a manual operation or configured to start the manual driving mode, in a case that the second route is generated by the route generation unit in a state that the automated driving mode control unit is performing the automated driving mode, and
wherein the route change determination unit is configured to determine that it is possible to change the first route to the second route when the mode changing unit has completed changing the automated driving mode to the manual driving mode.

2. The automated driving control device according to claim 1 , wherein the route change determination unit is configured to determine that it is not possible to change the first route to the second route when the mode changing unit has not completed changing the automated driving mode to the manual driving mode within a predetermined time.

3. The automated driving control device according to claim 2 , wherein in a case that the route change determination unit has determined that it is not possible to change the first route to the second route, the automated driving mode control unit is configured to continue to perform the automated driving mode on a basis of the first route.

4. The automated driving control device according to claim 2 , wherein in a case that the route generation unit generates the second route in a state that the automated driving mode control unit is performing the automated driving mode, the automated driving mode control unit is configured to start to decelerate the vehicle,
in a case that the route change determination unit has determined that it is not possible to change the first route to the second route, the automated driving mode control unit is configured to stop traveling of the vehicle.

5. The automated driving control device according to claim 1 , comprising:
a display device or a sound output device configured to report to an occupant of the vehicle that a condition to start the automated driving, which is for performing the automated driving mode in the automated driving allowed section, is satisfied; and
a switch configured to confirm whether the occupant of the vehicle has an intention to start automated driving in accordance with a report from the display device or the sound output device,
wherein in a case that the switch has confirmed the intention to start the automated driving, the automated driving mode control unit is configured to perform the automated driving mode.

6. The automated driving control device according to claim 1 , comprising a display device or a sound output device configured to notify the occupant that, in a case that the automated driving allowed section included in the second route is not different from the automated driving allowed section included in the first route, a route other than the automated driving allowed section included in the second route is changed.

7. An automated driving control device comprising:
a navigation device configured to store a road map and an automated driving allowed section on the road map, and configured to set a first route to a destination including the automated driving allowed section on a basis of a current position of a vehicle; and
one or more first processors functioning as an automated driving mode control unit configured to perform an automated driving mode in which acceleration/deceleration and steering of the vehicle are automatically controlled in the automated driving allowed section included in the first route,
wherein the navigation device comprises one or more second processors functioning as:
a route generation unit configured to generate a second route which is different from the first route on a basis of a predetermined condition; and
a route change prohibiting unit configured to prohibit changing of the first route to the second route, in a case that the automated driving allowed section included in the second route is different from the automated driving allowed section included in the first route.

8. An automated driving control device comprising:
a navigation device configured to store a road map and an automated driving allowed section on the road map, and configured to set a first route to a destination including the automated driving allowed section on a basis of a current position of a vehicle; and
one or more first processors functioning as an automated driving mode control unit configured to perform an automated driving mode in which acceleration/deceleration and steering of the vehicle are automatically controlled in the automated driving allowed section included in the first route,
wherein the navigation device comprises one or more second processors functioning as a route generation prohibiting unit configured to prohibit generation of a second route which is different from the first route, in a case that the first route includes the automated driving allowed section.
