Abstract:
1. A fuel efficiency ranking method for a vehicle driver, comprising: selecting as a category one or more factors and selecting as a variable another one or more factors, among a plurality of factors affecting fuel efficiency; collecting, by a communications device, a vehicle data including the variable and the fuel efficiency associated with a trip whenever a specific vehicle driver performs a trip; calculating, by the communications device, an average of the fuel efficiency and an average of the variable to set the averages as a fuel efficiency and a variable of the trip upon completion of the trip; classifying, by a first server, the fuel efficiency and variable of the trip into the category corresponding to the vehicle driver to store them; statistically processing, by a second server, the fuel efficiency of the trip corresponding to the category corresponding to the vehicle driver for every coordinate point of the variable to calculate an average of the fuel efficiency and a standard deviation of the fuel efficiency; regularizing, by the second server, the fuel efficiency of the trip based on the standard deviation of the fuel efficiency and the average of the fuel efficiency (hereinafter, the regularized fuel efficiency is referred to as GAP), wherein GAP=(corresponding fuel efficiencies−average values of fuel efficiencies)/(standard deviation of fuel efficiencies); ranking, by the second server, each vehicle driver in the order of a magnitude of an accumulated average of the GAP, based on the order in which the corresponding driver's GAP value appears on a GAP list; and transmitting, by the communications device, the resultant ranking evaluation to each vehicle driver via a communications network, wherein the second server of data center stores a previous GAP value of a previous driver in the GAP list prepared for each trip, and calculates the accumulated average values of GAP for a predetermined term whenever the GAP value is obtained for each trip thereby renewing the GAP list, and wherein the renewing is performed for other driver's GAP values and a corresponding driver's GAP value, and a latest GAP lists obtained is listed in the order of the GAP values.
