1. A vehicle energy management device used in a vehicle including a plurality of vehicle instruments driven by different energy sources, the vehicle energy management device comprising:

  • a processor to execute a software program; and

    a memory to store the program which, when executed by the processor, performs processes of;

    calculating a traveling route of said vehicle;

    dividing said traveling route into a plurality of traveling sections, and setting for each of the traveling sections a road category corresponding to road characteristics of each of the traveling sections;

    acquiring energy consumption related information that is information related to energy consumption of said vehicle in each of the traveling sections;

    acquiring own vehicle traveling characteristic information that is an actually measured value of traveling characteristics when said vehicle travels on a road of each road category and general vehicle traveling characteristic statistical information that is a statistical result acquired by statistically processing traveling characteristics of a plurality of general vehicles for each road category when the plurality of general vehicles travels on the road of each road category, and correcting said energy consumption related information of each of the traveling sections based on a result of comparing said own vehicle traveling characteristic information and said general vehicle traveling characteristic statistical information of each of the traveling sections;

    calculating an estimated value of an energy consumption amount by each of said plurality of vehicle instruments when said vehicle travels in each of the traveling sections, based on said corrected energy consumption related information;

    producing a control plan for said plurality of vehicle instruments for each of the traveling sections based on the estimated value of the energy consumption amount by each of said plurality of vehicle instruments in each of the traveling sections; and

    controlling said plurality of vehicle instruments according to said control plan.
