an automated driving determiner section configured to determine whether the vehicle is provided with an automated driving function to perform an automated driving, wherein

in response to the automated driving determiner section determining that the vehicle is not provided with an automated driving function, the display processor section prevents the information on the manual driving amount represented by the numerical value with respect to each of the plurality of routes from being displayed in the route selection screen view.

3. The navigation system according to claim 1 , wherein

the display processor section displays, as the information on the manual driving amount represented by the numerical value with respect to each of the plurality of routes in the route selection screen view, at least either (i) the automated driving enabled distance or (ii) a manual driving distance that is a distance, which is within each of the plurality of routes and is needed by the user to perform the manual driving.

4. The navigation system according to claim 1 , wherein

the display processor section displays,

as the information on the manual driving amount represented by the numerical value with respect to each of the plurality of routes in the route selection screen view,

(a) a full length of each of the plurality of routes and

(b) at least either (i) the automated driving enabled distance or (ii) a manual driving distance that is a distance, which is within each of the plurality of routes and is needed by the user to perform the manual driving.

5. The navigation system according to claim 1 , wherein

the display processor section displays, as the information on the manual driving amount represented by the numerical value with respect to each of the plurality of routes in the route selection screen view, at least either (i) a manual driving period of time that is a predicted value of a period of time for performing the manual driving in each of the plurality of routes, or (ii) an automated driving period of time that is a predicted value of a period of time for performing an automated driving in each of the plurality of routes.

6. The navigation system according to claim 1 , wherein

the display processor section is configured to display a minimum route selection button in the route selection screen view,

in response to the minimum route selection button being actuated, the display processor section is further configured to display a route from the plurality of routes with a minimum distance or minimum period of time for performing the manual driving.

7. The navigation system according to claim 1 , wherein

the display processor section displays, as the information for the manual driving amount represented by the numerical value with respect to each of the plurality of routes in the route selection screen view,

(a) a full length of each of the plurality of routes, and

(b) a manual driving distance within each of the plurality of routes, and wherein

the numerical value includes the full length of each of the plurality of routes and a corresponding manual driving distance for each of the plurality of routes, and wherein

the full length of each of the plurality of routes is displayed side by side with a corresponding manual driving distance for each of the plurality of routes to provide a comparison of each of the plurality of routes.

8. The navigation system according to claim 1 , wherein

the display processor section is further configured to display a minimum route selection button in the route selection screen view in addition to the information on the manual driving amount with respect to each of the plurality of routes and represented by the numerical value, and

in response to the minimum route selection button being actuated, the display processor section is further configured to display a route from the plurality of routes with a minimum distance or minimum period of time for performing the manual driving.

9. A navigation system that displays candidates of routes to a destination, which is designated by a user, on a display in a vehicle, the navigation system comprising:

a destination acquirer section configured to acquire the destination;

a departure place acquirer section configured to acquire a departure place of the vehicle;

a route calculator section configured to calculate a plurality of routes as route candidates from the departure place acquired by the departure place acquirer section to the destination acquired by the destination acquirer section;

an automated driving compliant road memory configured to store data that indicate automated driving compliant roads on which driving by an automated driving is permitted;

an automated driving distance calculator section configured to calculate an automated driving enabled distance that is a distance of automated driving compliant roads that are included in each of the plurality of routes calculated by the route calculator section, based on the data stored in the automated driving compliant road memory;

a minimum route identifier section configured to identify a load minimum route among the plurality of routes based on the automated driving enabled distance with respect to each of the plurality of routes calculated by the automated driving distance calculator section, the load minimum route being a route in which either a distance or a period of time for performing a manual driving is minimum among the plurality of routes; and

a display processor section configured to display on the display a route selection screen view for the user to select a route adopted as a planned travel route from the plurality of routes calculated by the route calculator section, the display processor section being further configured to display a minimum route selection button in the route selection screen view, and in response to the minimum route selection button being actuated, the display processor section is further configured to display the load minimum route identified by the minimum route identifier section among the plurality of routes.

10. The navigation system according to claim 9 , wherein

the route selection screen view displayed by the display processor section on the display includes information on the plurality of routes in addition to the minimum route selection button.

11. The navigation system according to claim 10 , wherein

the information in the route selection screen view is represented by a numerical value for a manual driving amount with respect to each of the plurality of routes, the information represented by the numerical value for the manual driving amount being determined depending on the automated driving enabled distance calculated by the automated driving distance calculator section with respect to each of the plurality of routes, the information represented by the numerical value for the manual driving amount for displaying a distance or a period of time for performing a manual driving in each of the plurality of routes.
