Abstract: A travel plan generation device generates a travel plan in which a vehicle passes through a first supply facility for supplying energy for travel of the vehicle, acquires supply availability information on the energy of the first supply facility at a predetermined timing after the vehicle starts traveling based on the generated travel plan, determines whether or not supply of energy is available at the first supply facility based on the supply availability information, when determining that the supply of the energy is not available at the first supply facility, identifies a second supply facility different from the first supply facility, and generates the travel plan in which the vehicle passes through the second supply facility instead of the first supply facility.

Abstract: An information processing method, an information processing system, an information processing device, and an information terminal of the present invention, accepts a destination for the vehicle, then searches for the travel route to the destination and sets as a first travel route, and sets a travel start time to start traveling on the first travel route. Then, vehicle information is acquired for the vehicle in advance of the travel start time by a prescribed time after the setting of the first travel route; and a travel route to the destination is searched again and a second travel route is set based on the vehicle information.

Abstract: An information processing method, an information processing system, an information processing device, and an information terminal are configured to set a first time at which a vehicle will start traveling on a travel route based on an operation accepted from a user via a terminal, and set a second time at which a notification to the user will be issued based on a position of the terminal, a position of the vehicle, and the first time.

Abstract: An information providing system (1) for providing a passenger with information includes an in-vehicle device (30) installed in an electric vehicle (EVn), wherein the passenger is provided with the information via the in-vehicle device (30). The in-vehicle device (30) includes a notifier (38) for notifying the passenger of a congested state of a charge station candidate (CS1). The notifying is implemented by estimating (42) of the congested state of the charge station candidate (CS1) at a time point when an own electric vehicle (EV1) reaches the charge station candidate (CS1) which is a charge station (CS) reachable with a state-of-charge (SOC) of the own electric vehicle (EV1), and the estimating (42) is implemented based on: position information and the state-of-charge (SOC) of the own electric vehicle (EV1), and position information and a state-of-charge (SOC) of another electric vehicle (EV2-EVn) which is present around the charge station candidate (CS1).

Abstract: A battery charge amount increase facility information provision device provides information relating to a battery charge amount increase facility to a vehicle installed with a battery (60) that is charged using an external power supply. The device includes a current position sensor (51) which detects a current position of the vehicle, a charge amount sensor (52) which detects a battery charge amount (SOC), a database (20) which registers the formation relating to the battery charge amount increase facility, and a controller (10). The controller (10) registers the current position of the vehicle in the database (20) as a location of a battery charge amount increase facility when the SOC has increased under a predetermined condition (S113). As a result, an amount of information relating to the locations of usable battery charge amount increase facilities is increased.

Abstract: A driving support system including: a vehicle location detector which detects current location and velocity vector of a vehicle; a traffic and road information database which stores point information of points on a route of the vehicle; a point information acquisition unit which acquires, from the database, the point information of the approaching points located in a given distance from the vehicle current location, based on the detected vehicle current location and velocity vector; a display device which provides displays of the acquired point information on a horizontally long screen thereof along a windshield of the vehicle; and a display control unit for controlling the display device. The display control unit determines display positions on the screen to display the point information, based on a positional relationship between the current location of the vehicle and the points where the point information related thereto are displayed.

Abstract: A curvature radius calculator employs point sequence data of map information representing a road shape, for calculation to determine a curvature radius of a curved interval of a travel path of a vehicle, a shape pattern decider employs the point sequence data to decide a shape pattern of the curved interval, a curvature radius corrector corrects the curvature radius, commensurately with a decision result of the shape pattern decider, and a curved interval extractor selects prescribed intervals of the travel path as targets, and extracts therefrom an interval meting preset conditions on an average of link lengths representing spacings between sequential two points of the point sequence data, respectively; an extreme as a maximum or minimum of the link lengths, and an average of link angles representing angles between adjacent two links, respectively, allowing the curvature radius calculator to use point sequence data of the extracted curved interval, to acquire a curvature radius of the curved interval.
