NAVIGATION DEVICE, NAVIGATION METHOD, NAVIGATION PROGRAM AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To precisely estimate energy consumption in a travel section and a travelable range of a vehicle.

SOLUTION: A navigation device 100 performs guidance of a route to a destination by using a guide image arranging a plurality of guide signs indicating guidance directions at respective predetermined guidance spots, from a near side in order of proximity to a current position. The navigation device 100 comprises a setting unit 101, an extraction unit 102, a calculation unit 103 and a display control unit 104. The setting unit 101 presets a first predetermined distance from the current position. The extraction unit 102 extracts a predetermined guidance spot on the route. The calculation unit 103 calculates a distance from the current position to the predetermined guidance spot extracted by the extraction unit 102. When the distance to the predetermined guidance spot that is calculated by the calculation unit 103 becomes equal to or less than the first predetermined distance, the display control unit 104 changes a color of the guide sign at the guidance spot in a different color from what has been displayed.
