Abstract:
1. A method for computing fuel consumption for a plurality of speed ranges of a route interval for a vehicle running from a departure point to a destination and for displaying a minimum fuel consumption route from the departure point to the destination, the method comprising: receiving actual fuel consumption data reported by a plurality of probe vehicles for a first portion of the plurality of speed ranges, wherein a second portion of the plurality of speed ranges lacks actual fuel consumption data; determining from the actual fuel consumption data of the first portion of the plurality of speed ranges, using a computer processor, a fuel consumption initial value formula and a trend line associated with the fuel consumption initial value formula; determining, using a computer processor, for each speed range of the first portion of the plurality of speed ranges, an average fuel consumption value based on the fuel consumption initial value formula and the trend line; determining, using a computer processor, for each speed range of the second portion of the plurality of speed ranges, an average fuel consumption value based on the fuel consumption initial value formula and the trend line; determining the minimum fuel consumption route using the average fuel consumption values of the first and second portions of the plurality of speed ranges; and displaying on a computer display unit the minimum fuel consumption route.
