Information providing system, server, onboard device, and information providing method

A server comprising:

• one or more communication modules configured to transmit information to and receive information from an onboard device or a mobile terminal;
• and
• one or more processors configured to
• acquire captured image data which is transmitted from the mobile terminal and position information corresponding to the captured image data, to extract a power source price from the captured image data,
• generate information of the power source station including the power source price and the position information,
• acquire a current position and an output mode which are transmitted from the onboard device,
• prioritize power source stations which are located within a predetermined range from the current position based on the output mode,
• provide information of the prioritized power source stations as recommendation information of the prioritized power source station to the onboard device.

An information providing method which is performed by an onboard device and a server configured to transmit information to and receive information from the onboard device, the information providing method comprising:

• storing, by the server, information of power source stations including position information of the power source stations and power source price information which are detected from captured images of the power source stations that are captured by a mobile terminal;
• acquiring, by the onboard device, a current position and an output mode and to transmit the acquired current position and the acquired output mode to the server;
• prioritizing, by the server, power source stations which are located within a predetermined range from the current position based on the output mode and to provide information of the prioritized power source stations as recommendation information of the power source stations to the onboard device;
• generating, by the server, the information of the power source stations including the power source price information and position information corresponding to the captured image data;
• and
• outputting, by the onboard device, the recommendation information of the power source stations which is received from the server.
