Energy consumption estimation apparatus, the energy consumption estimation method, energy consumption estimating program and recording medium

A precisely estimate the energy consumption in traveling section, and accurately estimate to be the travelable range of the vehicle. A travel distance estimation apparatus 100, predetermined segment of travel of the moving body (hereinafter, referred to as "travel section") estimates the traveling distance of the moving body in. Current position acquisition unit 101 acquires the current position of the moving body. Variable acquiring unit 102 acquires the information on the velocity of the moving body in the travel segment. Estimating unit 103, based on the energy expenditure estimating equation to estimate the energy consumption and the travel distance when traveling the travel section. Correcting unit 104 corrects the information related to the mobile for use as a variable of the energy consumption estimation equation. Storage unit 105 stores information about the road according to the travel history of the vehicle. Display unit 110 displays the map data including information about the travel distance calculated by the estimation unit 103. .FIELD 1
