<p>PURPOSE: A method and a system for ranking fuel efficiency influenced by drivers are provided to consider environmental factors and traffic factors. CONSTITUTION: As to a method for ranking fuel efficiency influenced by drivers, several factors influencing to fuel efficiency are selected as categories, and the other factors influencing to the fuel efficiency are selected as variables. While a certain driver drives for the time from turning on an ignition switch to turning off the ignition switch, vehicle data including fuel efficiency and the variables is collected. And a process of driving for the time from turning on the ignition switch to turning off the ignition switch is called one trip. When the trip is finished, the fuel efficiency and variables of the trip are decided by outputting the average of the fuel efficiency and variables. The fuel efficiency and variables of the trip are classed as the category, in which the driver is affiliated(S40). The fuel efficiency of the trip is normalized Based on the average of the fuel efficiency and the standard deviation of the fuel efficiency. The normalized fuel efficiency is called GAP. Cumulative averages of the GAP of each driver is ranked in the order, in which the cumulative average is higher(S60).</p> |
