Abstract

An input of a destination and an input of a desired number of power supply facilities via which a vehicle travels on a route from a present location to the destination until an amount of power available becomes 0 are received. The number of facilities are selected and the route to the destination via the number of facilities is specified, the number of facilities being selected such that an amount of power with which the vehicle is able to travel a distance obtained by adding a margin distance to a distance to a farthest facility is less than the amount of power available when the route is specified. An alert is reported when the amount of power available is less than an amount of power required to travel the distance obtained by adding the margin distance to the distance to the farthest facility of the selected facilities.

First claim

What is claimed is:

1 . An alerting device of an electrically powered vehicle including a power storage device that supplies power to be used for traveling, the alerting device comprising:
an input unit that receives an input of a destination from a user and that receives, from the user, an input of a desired number of power supply facilities via which the electrically powered vehicle travels on a route from a present location to the destination until an amount of power available in the power storage device becomes 0; a controller that selects the desired number of power supply facilities and that specifies the route to the destination received by the input unit via the selected desired number of power supply facilities in order from a power supply facility nearest to the present location, the desired number of power supply facilities being selected such that an amount of power with which the electrically powered vehicle is able to travel a distance obtained by adding a margin distance to a distance to a farthest power supply facility is less than the amount of power available in the power storage device when the route is specified; and a reporting unit that reports an alert to the user when, during traveling on the route specified by the controller, the amount of power available in the power storage device is less than an amount of power required to travel the distance obtained by adding the margin distance to the distance to the farthest power supply facility of the power supply facilities selected by the controller.

2 . The alerting device of the electrically powered vehicle according to claim 1 , wherein the margin distance is able to be set by the user.
