Abstract:
1. A fuel efficiency information management method comprising steps of: determining, by a processor, a fuel efficiency and a travel state factor serving as a variation factor of the fuel efficiency in a predefined period for each of a plurality of vehicles, the variation factor including at least a vehicular model, a manipulated amount of an accelerator, a manipulated amount of a brake pedal, a frequency of idling, number of boarding passengers, and an active amount of time of an air conditioner; storing a map information of a road which includes slop angle or type of up or down, or a road traffic information of a road which includes traffic flow or frequency of occurrence of traffic jams; calculating the fuel efficiency when a value or content of a specified travel state factor, which is defined through operations on a predefined terminal device by a user, in a plurality of actual travel state factors is altered to a different value or content; determining, by a processor, a frequency of ups and downs or an average slope angle of a road traveled by the vehicle on the basis of a temporal position of the vehicle with reference to the map information stored in the data base; correcting the fuel efficiency to be higher than an actual value as the frequency of the ups and downs becomes higher or the average slope becomes greater; transmitting an eco-information containing the specified travel state factor and a ranking corresponding to a corrected fuel efficiency to the predefined terminal device; and displaying the eco-information of each vehicle containing a ranking corresponding to a level of the fuel efficiency and the travel state factor via the predefined terminal device.
