<p>An acquiring unit (711) of each of vehicle-mounted devices (7101, 7102, ...) acquires information relating to vehicle speed, information relating to operations such as acceleration, foot braking, and handling by the driver, and information relating to charging and discharging of a battery unit for each predetermined period of time. The acquisition results are reported to a server device (720), and histories of traveling record information are generated. When a planned travel path is searched by a searching unit (713) of each vehicle-mounted device, planned traveling information is set to the server device (720). A retrieving unit (723) of the server device (720) retrieves information relating to optimum driving in which energy supplied from the battery unit is used most efficiently for each divided sections of the planned travel path from the history of the traveling record information corresponding to the planned traveling information. The optimum driving information is transmitted from a transmitting unit (724) to the vehicle-mounted device that set the planned traveling information. When the vehicle-mounted device receives the optimum driving information, a presenting unit (715) presents driving support information relating to the planned travel path for the vehicle.</p> |
