Mobile-object information acquiring apparatus, mobile-object information acquiring method, mobile-object information acquiring program, and recording medium

A mobile-object information acquiring apparatus comprising:

• a current-information acquiring unit that acquires energy consumption (hereinafter, “actual energy consumption”) accompanying travel of a mobile object;
• a setting unit that sets for each factor of a plurality of factors causing energy consumption of the mobile object to change, information related to the mobile object having the factor;
• an estimating unit that based on the information related to the mobile object for a reference point in time and set by the setting unit, estimates energy consumption consequent to travel (hereinafter, “reference energy consumption”);
• and
• a calculating unit that for each of the factors, calculates an amount of change of the actual energy consumption with respect to the reference energy consumption.

A mobile-object information acquiring apparatus comprising:

• a current-information acquiring unit that acquires energy consumption (hereinafter, “actual energy consumption”) accompanying travel of a mobile object;
• an estimating unit that based on the actual energy consumption and for each factor causing energy consumption of the mobile object to change, respectively estimates information related to the mobile object affected by the factor;
• a recording unit that records the information that is related to the mobile object and estimated by the estimating unit;
• and
• a calculating unit that calculates for each factor and with respect to information that is related to the mobile object and recorded by the recording unit at a past given point in time, an amount of change of the information that that is related to the mobile object and estimated by the estimating unit.

A mobile-object information acquiring method of a mobile-object information acquiring apparatus that acquires information of a mobile object, the method comprising:

• acquiring actual energy consumption accompanying travel of the mobile object;
• separating the actual energy consumption according to factors causing energy consumption of the mobile object to change and estimating actual energy consumption caused by each factor;
• acquiring for each factor, reference energy consumption accompanying the travel of the mobile object at a reference point in time;
• and
• calculating for each factor, an amount of change of the actual energy consumption with respect to the reference energy consumption.
