Abstract:
1. A route setting device comprising: a current location detecting section configured to detect a current vehicle location of a host vehicle; a transit point setting section configured to set a user selected transit point based on a user setting instruction from a user; a recommended route calculating section configured to calculate a first recommended route from the current vehicle location to a destination via the user selected transit point; and a transit point determining section configured to determine, based on the user setting instruction, whether the user selected transit point set by the transit point setting section is a disposable type of transit point through which a subsequently recommended route, that is calculated after the first recommended route, is not required to pass, and to determine, based on the user setting instruction, whether the transit point set by the transit point setting section is a substitutable type of transit point in for which an alternative transit point can be substituted so that the subsequently recommended route can pass through the alternative transit point, the recommended route calculating section being further configured to calculate as the subsequently recommended route a non transit point recommended route from the current vehicle location to the destination without requiring the user selected transit point to be located along the non transit point recommended route when the user selected transit point is determined to be the disposable type by the transit point determining section, and being further configured to calculate as the subsequently recommended route an alternative transit point recommended route from the current vehicle location to the destination with the alternative transit point being located along the alternative transit point recommended route when the user selected transit point is determined to be the substitutable type by the transit point determining section.
