Method of predicting energy consumption, apparatus for predicting energy consumption, and terminal apparatus
First Claim
1. A method of predicting energy consumption by a system for predicting energy consumption, the system having an energy consumption prediction apparatus and at least one terminal apparatus, wherein the energy consumption prediction apparatus delivers data for route search to the terminal apparatus and the terminal apparatus performs route displaying, based on the delivered data, the method comprising:
- by the energy consumption prediction apparatus,calculating geographic characteristic values of each of links that form a road, based on energy consumptions collected from probe vehicles, wherein geography of the each link affects consumption energy thereof with the geographic characteristic values;
calculating a predicted energy consumption of each link selected as a prediction target, based on the geographic characteristic values; and
delivering the each predicted energy consumption having been calculated to the terminal apparatus;
and by the terminal apparatus,outputting route guide information from an output section, based on the predicted energy consumptions having been delivered.

Abstract
An object of the invention is to predict energy consumptions of a vehicle, using geographic characteristic values which are independent from particular driving patterns and vehicle parameters and unique to respective links. A navigation server predicts energies which are consumed when a vehicle runs on links. The navigation server calculates geographic characteristic values of respective links, the geography of the each link affecting the consumption energy with the geographic characteristic values, the calculation being based on energy consumptions collected from probe vehicles, and calculates predicted energy consumption of each link selected as a processing target, based on the geographic characteristic values. A navigation terminal obtains these predicted energy consumptions and performs route search with the obtained predicted energy consumptions as costs.
