Abstract

A route guidance system, a route guidance method, and a computer program are provided that enable a user to understand in advance a section where automated driving control is interrupted. The route guidance system is configured to: when a recommended route from a departure point to a destination including an automated driving section where automated driving control of a vehicle is performed is searched for, acquire candidate routes that are candidates for the recommended route; specify, for each of the candidate routes, an interruption section where the automated driving control is interrupted in the automated driving section included in the candidate route; and provide guidance, for each of the candidate routes, in a manner distinguishing a section that corresponds to the interruption section from a section that does not correspond thereto in the automated driving section included in the candidate route.

First claim

1 . A route guidance system comprising:
route acquisition code for acquiring a planned traveling route of a vehicle including an automated driving section where automated driving control of the vehicle is performed; interruption section specifying code for specifying an interruption section where the automated driving control is interrupted in the automated driving section included in the planned traveling route; and route guidance code for providing guidance for the planned traveling route in a manner distinguishing a section that corresponds to the interruption section from a section that does not correspond thereto in the automated driving section included in the planned traveling route.

2 . A route guidance system comprising:
route acquisition code for acquiring a planned traveling route of a vehicle including an automated driving section where automated driving control of the vehicle is performed; interruption-predicted section specifying code for specifying an interruption-predicted section where there is a possibility that the automated driving control will be interrupted in the automated driving section included in the planned traveling route; and route guidance code for providing guidance for the planned traveling route in a manner distinguishing a section that corresponds to the interruption-predicted section from a section that does not correspond thereto in the automated driving section included in the planned traveling route.

3 . The route guidance system according to claim 1 , further comprising interruption information acquisition code, based on the interruption section specified by the interruption section specifying code, acquiring interruption information indicating that the automated driving control is interrupted in the automated driving section included in the planned traveling route, wherein
the route guidance code provides guidance about the planned traveling route and also about the interruption information acquired by the interruption information acquisition code.

4 . The route guidance system according to claim 3 , wherein the interruption information contains any of number of times, a duration, and a distance of the interruption of the automated driving control and a reason for the interruption.

5 . The route guidance system according to claim 2 , further comprising interruption-predicting information acquisition code, based on the interruption-predicted section specified by the interruption-predicted section specifying code, acquiring interruption predicting information indicating that the automated driving control is predicted to be interrupted in the automated driving section included in the planned traveling route, wherein
the route guidance code provides guidance about the planned traveling route and also about the interruption predicting information acquired by the interruption-predicting information acquisition code.

6 . The route guidance system according to claim 5 , wherein the interruption predicting information contains any of number of times, a duration, and a distance of the predicted interruption of the automated driving control and a reason for the interruption.

7 . The route guidance system according to claim 3 , wherein the planned traveling route includes a plurality of routes as candidates for a recommended route from a departure point to a destination, and
the route guidance code provides guidance for, out of a plurality of the planned traveling routes, a planned traveling route with a higher priority in a prioritized manner based on the interruption information or the interruption predicting information.

8 . The route guidance system according to claim 3 , wherein the planned traveling route includes a plurality of routes as candidates for a recommended route from a departure point to a destination, and
the route guidance code displays the interruption information or the interruption predicting information on a display device in a manner sorted in a table for each planned traveling route.

9 . The route guidance system according to claim 2 , further comprising interruption-probability acquisition code for acquiring an interruption probability that is a probability that the automated driving control will be interrupted in the interruption-predicted section, wherein
the route guidance code provides guidance about the section that corresponds to the interruption-predicted section in the automated driving section included in the planned traveling route in a manner depending on the interruption probability of the interruption-predicted section.

10 . The route guidance system according to claim 1 , wherein the route guidance code provides guidance about a section that corresponds to the interruption section or the interruption-predicted section and guidance about a section that does not corresponds thereto in the automated driving section included in the planned traveling route in different guidance manners.

11 . The route guidance system according to claim 1 , further including control content setting code, for a section in the automated driving section included in the planned traveling route from which the interruption section or the interruption-predicted section is excluded, setting control contents of the automated driving control that is performed on the vehicle.

12 . A route guidance system comprising:
route acquisition code for acquiring a planned traveling route of a vehicle including an automated driving section where the vehicle is allowed to perform automated driving control in addition to manual driving; manual-interruption section specifying code for specifying a manual-driving interruption section where the manual driving is interrupted and the automated driving control is performed in the automated driving section included in the planned traveling route; and route guidance code for providing guidance for the planned traveling route in a manner distinguishing a section that corresponds to the manual-driving interruption section from a section that does not correspond thereto in the automated driving section included in the planned traveling route.

13 . A route guidance system comprising:
route acquisition code for acquiring a planned traveling route of a vehicle including an automated driving section where the vehicle is allowed to perform automated driving control in addition to manual driving; manual-interruption-predicted section specifying code for specifying a manual-driving-interruption-predicted section where there is a possibility that the manual driving will be interrupted and the automated driving control will be performed in the automated driving section included in the planned traveling route; and route guidance code for providing guidance for the planned traveling route in a manner distinguishing a section that corresponds to the manual-driving-interruption-predicted section from a section that does not correspond thereto in the automated driving section included in the planned traveling route.

14 . A route guidance method comprising:
a step of, by route acquisition code, acquiring a planned traveling route of a vehicle including an automated driving section where automated driving control of the vehicle is performed; a step of, by interruption section specifying code, specifying an interruption section where the automated driving control is interrupted in the automated driving section included in the planned traveling route; and a step of, by route guidance code, providing guidance for the planned traveling route in a manner distinguishing a section that corresponds to the interruption section from a section that does not correspond thereto i
